Friends of Padre Steve’s World

A couple of days ago I reposted an article about the sinking of the HMS Hood by the German Battleship Bismarck. The story of the Bismarck is an epic saga of naval warfare and history. It is tragedy played out as if scripted by a playwright in three parts. The first was the sinking of the illustrious “Mighty” Hood by the Bismarck on May 24th 1941. 

The second, which I deal with today, was the pursuit and search for Bismarck by the British Home Fleet and the desperate attempt of the British to find a way, any way, to slow Bismarck down and bring her to battle, before she could return to the safety of Nazi occupied France.  The final chance to stop the mighty German Leviathan came as night fell on May 26th. 

I hope you appreciate the heroism of the men who flew the hopelessly obsolete aircraft who dealt the blow which crippled Bismarck. This is a re-write of past articles and I will post the final article about the sinking of the Bismarck tomorrow. 

There is one other thing to mention. I cannot imagine what it would have been to be a crewman on the Bismarck, knowing that nightfall would bring them safely unter the protection of the Luftwaffe, and then discover that there was no escape from death and destruction.

On May 24th 1941 the German Battleship Bismarck had sunk the celebrated Battlecruiser HMS Hood in the Denmark Strait and had seriously damaged the new Battleship HMS Prince of Wales. The news of the disaster stunned the Royal Navy. Fighting a war on multiple fronts and now standing alone against Hitler’s Germany the British deployed every warship available to find and sink Bismarck.

On the evening of the 24th of May Bismarck was being shadowed by the heavy cruisers HMS Norfolk and HMS Suffolk. To the east the ships of the Home Fleet, Britain’s last line of defense under the command Admiral John Tovey was making the fastest speed to intercept the Bismarck.  Far to the southeast, Vice Admiral James Sommerville’s  “Force H” comprised of the carrier HMS Ark Royal, the fast but elderly battlecruiser HMS Renown, and the light cruiser HMS Sheffield were ordered to leave the vital convoy which there were escorting and proceed to the northwest to join the hunt for the German battleship.

The Admiralty knew that the disaster could not be covered up, and within three hours of the battle sent out a press release detailing the situation: “British naval forces intercepted early this morning, off the coast of Greenland, German naval forces, including the battleship Bismarck. 

The enemy were attacked, and during the ensuing action H.M.S. Hood (Captain R. Kerr, C.B.E., R.N.) wearing the flag of Vice-Admiral L. F. Holland, C.B., received an unlucky hit in the magazine and blew up. The Bismarckhas received damage, and the pursuit of the enemy continues. It is feared there will be few survivors from H.M.S. Hood.

With Bismarck loose the North Atlantic Convoys on which Britain depended for her survival were vulnerable. The previous year the commander of the Bismarck task force Admiral Günther Lütjens with the Battlecruisers Scharnhorst and Gneisenau had wreaked havoc on the convoys. Now of Britain was on edge with the news of Bismarck’s break out into the Atlantic. Churchill was furious with the Navy when the Mighty Hood, the largest and most powerful ship in the Royal Navy destroyed with the loss of all but three crew members. Now every effort was directed to find and sink the Bismarck.

Swiftly ships were redeployed to find, sink, and prevent Bismarck intercepting and destroying any of the eleven convoys then at sea. HMS Rodney and the Sixth Destroyer Flotilla made up the Tribal Class Destroyers Somali, Tartar, Mashona, and Eskimo, was west of Ireland escorting the passenger liner RMS Britannic which was serving as a troopship even as Rodney made her way to Boston for a major refit, including her notoriously unreliable engineering plant. Leaving the Eskimo behind to escort, Rodney and the other three destroyers steamed to join Tovey and King George V. Likewise, HMS Ramillies was detached from Convoy HX-127 South of Cape Farewell, to intercept Bismarck from the west, and her sister ship HMS Revenge was dispatched from Halifax, Nova Scotia with the same mission. The elderly Ramillies and Revenge would have have stood little chance in an engagement with Bismarck, but they were better than nothing.

Accompanying the Home Fleet was the brand new Aircraft Carrier HMS Victorious with 824 Naval Air Squadron embarked under the command of LCDR Eugene Esmond. The squadron, like many in the Fleet Air Arm was equipped with Fairey Swordfish Torpedo Bombers. The squadron had seen action aboard other carriers in the North Atlantic, the Norway Campaign and in the Mediterranean before being assigned to the Victorious. On the night of 24 May 1941, in foul North Atlantic weather the Victorious launched nine Swordfish from a range of 120 miles in a desperate attempt to slow the Bismarck down. Esmond’s squadron scored one hit amidships on the Bismarck which did no damage except to scratch and dent the armor plate of Bismarck’s main belt.

824 Squadron Swordfish on HMS Victorious

About 6 hours after the attack by Victorious’s Swordfish, Bismarck shook her pursuers and disappeared into the mists of the North Atlantic, while her consort, the Heavy Cruiser Prinz Eugen escaped to the northwest in order to conduct independent raiding operations. Not knowing the location or course of the Bismarck the Royal Navy frantically searched for the German Leviathan. Most of the ships nearest to Bismarck’s last reported position, like Victorious and Repulse were low on fuel, others like Prince of Wales damaged, and others, like Force H seemed too far away to be of any importance in the search.

However the British were able to intercept and decode some German communications which indicated that Lütjens had orders to steam to Brest, in German occupied France for repairs. Brest had good repair facilities and both Scharnhorst and Gneisenau were undergoing repairs there. However, as far as the British knew, Lütjens might have doubled back through the Denmark Strait to Norway.

Though the British believed that the Bismarck could be headed toward Brest they could not be sure, as each hour passed the chances of finding and bringing Bismarck to battle diminished. For nearly 36 hours the British searched in vain for the Bismarck, and for much of the 25th Tovey’s squadron was searching in the wrong direction.

For over 30 hours the British had no idea where Bismarck was or might be heading. Winston Churchill was livid. He was angry at the loss of Hood and Bismarck’s evasion of ships shadowing her. Then at 1030 on the 26th of May the luck of the British changed.

After breaking clear of Prince of Wales, Norfolk, and Suffolk, the crew of the Bismarck believed with every hour that they would soon Be safe. They expected that by the morning of the 27th they would under the protection of Herman Goering’s Luftwaffe and safely in France. But, the good fortune of the British was the worst thing that could happen to the 2200 men aboard Bismarck.

On that morning a Royal Air Force Coastal Command PBY Catalina co-piloted by US Navy Ensign Leonard Smith found the Bismarck. The aircraft was holed by anti-aircraft fire, but sent out the following message:

One battleship, bearing 240º, distance 5 miles, course 150º. My position 49º 33′ North, 21º 47′ West. Time of transmission 1030/26.”

Once Smith transmitted Bismarck’s location every available ship converged on her location,  but unless something could be done to slow the Bismarck down, the chances bringing her to battle diminished by the hour.

The only heavy forces close enough to successfully engage Bismarck, Tovey’s battleships HMS King George V and HMS Rodney were over 120 miles behind Bismarck, too far away to intervene unless Bismarck changed course or could be slowed down. Ramillies and Revenge were far to the west and too slow to intercept.

This left Somerville’s Force H to the south, but it did not have the combat power to survive a surface engagement with the Bismarck should they encounter her without the support of other heavy fleet units. Even so Sommerville was willing to risk the Renown in a suicidal action to bring Bismarck to battle if it would allow Tovey to catch her before she could escape. Desperation was the order of the day for both sides.

The situation was desperate. If Bismarck could not be slowed down before dark she would be in range of heavy Luftwaffe Air support as well as support from U-Boats and destroyers based in France. Unless something akin to a miracle occurred Bismarck, would join the Scharnhorst and Gneisenau in Brest and with the addition of Bismarck’s sister-ship Tirpitz form a surface squadron strong enough to devastate British shipping in the Atlantic.

Ark Royal’s aircraft were the last hope of slowing down Bismarck before she could effect her escape and emerge from the Atlantic after having dealt the Royal Navy a devastating blow.

The strike aircraft available on Ark Royal were the most unlikely aircraft imaginable to successfully carry out such a mission. Ark Royal’s 820 Squadron, like Victorious’ 825 Squadron it was equipped with Fairey Swordfish Mk 1 Torpedo Bombers. These were biplanes with their crew compartment exposed to the weather.

The Swordfish entered service to the Navy in 1936. By all standards these aircraft were antique compared with most aircraft of its day. Likewise, the Mark XII 18” torpedo carried by the aircraft was smaller or slower and equipped with a less powerful warhead than comparable torpedoes used by other navies. Despite their limitations the venerable Swordfish had performed admirably during the early part of the war sinking or damaging three Italian battleships at Taranto in November 1940. Their success against the Italians at Taranto gave inspiration to the Japanese for their attack against the U.S. Pacific Fleet at Pearl Harbor the following year. But now, in the face of foul weather and a powerful opponent 820 Squadron’s Swordfish were all the Royal Navy had left to stop Bismarck before she could make her escape.

Bismarck steering erratically after the torpedo hit to her stern

With that in mind  Sommerville in sent his light cruiser, the  HMS Sheffield ahead to shadow Bismarck while Ark Royal closed in to launch her Swordfish against the German ship.  The first wave of aircraft strike were unaware Sheffield was near Bismarck mistakenly attacked the British cruiser. Thankfully, the new design magnetic detonators On the torpedoes failed to detonate,  saving Sheffield from destruction. With little daylight left the aircraft returned to Ark Royal where they rearmed with torpedoes equipped with contact fuzes and refueled by the flight deck crew, that labored in rain and 50 knot winds blowing across the carrier’s flight deck. Just before 8 p.m. 15 Swordfish of 820 Squadron took off for what they knew was the very last chance to attack Bismarck before night fell. If they failed Bismarck would most certainly escape.

As darkness began to fall the 15 Swordfish from 820 Squadron descended through the clouds to attack the German ship. Just fifteen obsolete aircraft and thirty men were attacking the most powerful warship afloat. They dispersed and attacked from all points of the compass. Bismarck twisted and turned and fired all of her guns at the attacking aircraft. The Germans fired with every weapon available, even the 15″ guns of her main battery, which she fired her into the ocean ahead of the Swordfish. It appeared for a moment that Bismarck had successfully avoided serious damage. All but two torpedoes missed.  One torpedo struck the German midships and barely dented her massive armor. However a second torpedo, launched by a Swordfish piloted by Lieutenant John Moffat hit Bismarck in her weakly protected stern. The target angle from the aircraft to Bismarck was poor and those aboard the battleship who saw the torpedo approach believed that it was certain to miss, but it hit.

The hit jammed Bismarck’s port rudder at a 12 degree angle, and destroyed her steering gear. Repair crews and divers were dispatched but the weather was such that German damage control teams could not repair her steering gear. This was mainly due to the most critical design flaw in the class and most other German Capital Ships, and Heavy Cruisers. The structure of the stern was inherently weak. Likewise, the design of the ship’s propulsion system used a three screw system with dual rudders. This was designed to save weight when most other capital ships used a four screw arrangement. The steering gear were hopelessly jammed and the three screw arrangement did not give Bismarck the ability to steer herself and main control just using her screws. The game was now over, except for the final engagement. Escape was now impossible.

After the hit Bismarck steamed in circles, unable to maneuver. This enabled Tovey with King George VRodney, the heavy cruisers Norfolk and Dorchester, as well as a number of destroyers to catch up with the hitherto elusive German battleship.

Bismarck’s senior surviving Engineering Officer, Korvettenkapitänen Gerhard Junack recalled the damage and attempts to restore maneuverability to the stricken ship:

    One torpedo which hit amidships caused no damage, but the second affected the rudders disastrously, jamming the port-side rudder at a 15º angle. Immediately, the Bismarck became no longer manoeuvrable.

  • The torpedo-hit on the rudder shook the ship so badly that even in my zone of action in the turbine-room, the deck-plates were thrown into the air, and the hull vibrated violently. Shortly after the blow, water flooded through the port-side gangways into the turbine-room, and clouds of gas and smoke filled the room until the forced ventilation cleared it.
  • The stern compartments of the ship were now flooding, but the men who had been stationed there could still be saved, and soon the carpenters and repair-crew came through, making their way aft. But the ship pitched so violently in the strong sea swell that it was impossible to keep a foothold in the turbulent water surging through the companion-way.
  • All possibilities were now being considered to restore the ship’s manoeuvrability – even if only temporarily. The Commander, Kapitän zur See Lindemann, considered reports from Chief Engineer Lehmann, who was in continual contact with the repair and rescue teams. There was much gesticulation, and at one point the Chief Engineer stepped out of the circle, walked away, turned about, and made a sign of complete refusal. What this was about I am not certain, but eventually it was found possible to connect the hand rudder. But the old rudder would not budge, and to attempt to cut it away with underwater saws was quite impossible because of the heavy swell. A proposal to force the rudder out from below with the help of explosives was rejected, because of the proximity to the propellers. Thus all experiments with the auxiliary rudder were given up as completely hopeless, with the old one immovable.”

The attacks of the antiquated Swordfish on the Bismarck achieved results that no one in the Royal Navy expected. When reports indicated that Bismarck had reversed course following the torpedo attack Tovey could not believe them. It was only when lookouts aboard Sheffield confirmed the reports from the Swordfish about Bismarck’s erratic movements that Tovey realized that Bismarck must have been damaged and was unable to maneuver.

It was a dramatic and unexpected turn of events. The German crew sank into gloom as the night went on and they dealt with torpedo attacks from the British Destroyers as Tovey’s battleships moved in for the kill. As darkness descended the destroyers of Captain Phillip Vians’s 4th Flotilla, the Tribal Class destroyers Cossack, Maori, Zulu, Sikh and the Free Polish Navy destroyer Piorun, closed with Bismarck subjecting her to a Lilliputian torture. The ships harassed and attacked the German ship with guns and torpedoes. Though their attacks did not succeed they kept the bulk of the Bismarck’s crew up and awake all night. They launched 16 torpedoes without a hit, but a star shell landed on Bismarck’s bow forcing damage control teams to race to the forecastle to extinguish the flames in order to prevent heavier ships nearby from shooting at her. As daylight arrived, Admiral Lütjens, his staff, and Bismarck’s Captain and watch standers prepared the ship for the inevitable confrontation with the British battleships and heavy cruisers.

Until tomorrow,

Peace,

An Experiment in Failure: The Beautiful, Flawed, Expensive, and Expendable Alaska Class Large Cruisers

Line drawing of Alaska in 1945

Friends of Padre Steve’s World,

The three ships of the Alaska Class were among the most confusing and curious designs of warships ever built for the US Navy. They had their genus in the early 1930s when the Germans deployed the Deutschland Class Pocket Battleships, which in reality were heavy cruisers with 11” guns designed for long range commerce raiders. Both the Americans and French began to design something larger and faster. The French produced the excellent Dunkerque Class which could be classed as as either a Battlecruiser, or Fast Battleship. The American designs languished on the drawing board due to bureaucratic conflicts between those who believed a specialized ship to track down commerce raiders was necessary, and those who thought such designs were a waste of money and resources.

Alaska and Guam Together 

However in the late 1930s a rumor of Japanese “super cruiser” put them back into the planning stage  with President Franklin Roosevelt being a supporter of the concept. In truth the Japanese had no such ship on the drawing board, but still the process of trying to figure out what the ship and its mission would be perplexed designers. Add this to political pressure and  the resulting confusion had nine different designs underway at the same time, everything from a 6,000 ton modification of the Atlanta Class anti-Aircraft cruiser, an enlarged heavy cruiser, to a 38,000 ton fast battleship. Eventually the Naval General Board Chose in essence what was a greatly enlarged, up-armored and up-gunned modification of the Baltimore Class heavy cruisers.

The confusion even manifested in what the Navy decided to call the class. Based on their size, speed and armament they looked like Battlecruisers, but if you compared them to other battlecruisers they had severe deficiencies in armor and anti-torpedo defenses when compared the the old but still effective British Hood, Repulse, and Renown, the French Dunkerque Class, the German Scharnhorst Class, and the Japanese Kongo Class, which were all battlecruisers or fast battleships.

The Navy classed them as Large Cruisers and deigned them as CB. The Navy designated Heavy Cruisers as CA, Light Cruisers as CL, and the US Navy’s one attempt to build large Battlecruisers, the Lexington Class were designated as CC before they were cancelled with two of the four ships , Lexington and Saratoga completed as Aircraft Carriers. Likewise the naming of the class straddled the line between States and Cities. Battleships were named after States, cruisers were named after cities, but the Alaska Class were named after territories. While Alaska and Hawaii became states later, they were not states at the time. The ambiguity of their names reflected the confusion of their design and mission.

They were designed to hunt and kill the German Pocket Battleships, the imagined large Japanese Cruisers, and as a counter the battlecruisers Scharnhorst and Gneisenau which in 1939 and 1940 had created havoc in the Atlantic raiding convoys and sinking the Royal Navy Aircraft Carrier HMS Courageous.


USS Missouri (Top) with USS Alaska (below) at Norfolk Naval Station 1944

As designed the ships were 809 feet long and 91 feet wide, displaced 27,000 tons, and mounted 9 12” guns in three turrets, and and were capable of 33 knots.  They used the expanded hull design of the Baltimore Class, and used the same propulsion system as the Essex Class Aircraft Carriers. The ships mounted a large anti-aircraft battery of twelve 5” 38 caliber Dual Purpose guns, fifty-six 40mm cannons in quad and twin mounts, and thirty four 20mm light anti-aircraft guns. But even this was less than they could have mounted. That was because instead of placing the ship’s aviation facilities on the fantail as was done on the Brooklyn Class Light Cruisers, the Heavy Cruiser Wichita, the Cleveland Class Light Cruisers, the Baltimore Class, and all the modern battleships, to the earlier midships aviation facilities including port and starboard catapults. The Navy’s experience in combat during the Guadalcanal Campaign showed this arrangement to be a vulnerability in surface actions. Despite this the design was not changed.

Their armor protection was proof against 8” and 11” shells but could not withstand the heavier shells of battleships. In addition, to keep the ships at their designed displacement, no below the waterline torpedo protection was provided. The lack of that would have made them vulnerable That being said they had a good anti-aircraft battery, could keep pace with the fast carriers, and conduct shore bombardment operations against the Japanese mainland. None engaged any type of ship that they were designed to fight. The Alaska and Guam were the only two ships of the class completed and which saw service in the war. They were both decommissioned having served barely two and a half years active service each. Hawaii was launched but construction was suspended when she was 84% complete, and she was never commissioned.

The Scharnhorst: She and the Gneisenau were the threat that the Alaska’s were designed to counter

Alaska was laid down in December 1941 shortly after Pearl Harbor, launched 15 August 1943 and commissioned on 17 June 1944. Her sister ship, Guam was launched on 12 November 1943 and commissioned 17 September 1944.  The final ship of the class to be built the Hawaii was launched after the war in November 1945 with her construction halted when she was 84% complete in 1947. Three planned ships, the Philippines, Puerto Rico and Samoa were never laid down.

Aerial View of USS Alaska

While fast and large with more than adequate firepower the purpose that they created for no longer existed by the time that they were commissioned.  Of the German Pocket Battleships, Graf Spee had been scuttled in 1939, while Lützow the former Deutschland, and Admiral Scheer were bottled up in the Baltic. The Scharnhorst had been sunk by a 12 ship British task force led by the HMS Duke of York on December 26th 1943 after mounting an attack on a Murmansk convoy at the Battle of North Cape.  Her sister Gneisenau had been heavily damaged in the “channel dash” and bombing in Kiel. While being refitted to replace her nine 11” guns with six 15” guns the work was discontinued after the sinking of the Scharnhorst. Her main battery and secondary armament were removed and used to reinforce the Atlantic Wall, mostly in Norway.

The USS Guam in 1945

With their natural opponents no longer a factor in the war the Alaska and Guam were sent to the Pacific where they spent their time escorting fast carrier task forces, conducting naval gunfire support missions off Okinawa and conducting sweeps in Japanese waters as part of the initial blockade of Japan.  Following the war Alaska and Guam were active in Operation Magic Carpet the return of US servicemen from the Far East to the United States. Alaska and Guam were decommissioned in February 1947 remaining in reserve until stricken from the Naval List. Alaska was scrapped in 1960 and Guam being in 1961. The fate of Hawaii was be debated for years. Suggestions included to complete here her as the first guided missile cruiser (CG) and later a Command Cruiser (CC) were rejected as too expensive and she was sold for scrap in 1959.

Incomplete and undervalued the Hawaii being towed to the breakers in 1959

The era of the Battle Cruiser which began with the launching of the HMS Invincible in 1907 culminated in with launching of the HMS Hood, or arguably the  Dunkerque or Scharnhorst Classes, but not with the Alaska Class. They looked a lot like battlecruisers, but that is where the similarity ended.  It was an ignominious ending for expensive and practically unused ships being broken up. But it had to be. Their lack of underwater protection, barely average armor protection, ill designed aviation facilities, and main battery which was unique, expensive, and had a tendency to break down ensured that they could not have another mission. Instead, for a much more affordable cost, Baltimore Class cruisers were converted into guided missile cruisers or retained as naval gunfire support ships. Likewise, Cleveland Class light cruisers were converted to guided missile cruisers. One of the Baltimore Class, the Norfolk was converted into a Command Cruiser, and two others converted into the light fleet carriers, and later command ships, Wright and Saipan. 

In light of the need for a combination of substantial naval gunfire support, on a platform large enough to support the latest Aegis air defense radars and missiles to protect an Expeditionary Strike Group, capable of ballistic missile defense, and equipped with combat proven 6”, 8”, or 16” guns for naval gunfire support missions, Tomahawk Cruise missiles, and the latest anti-ship missiles and close in protective missiles and guns is needed. The existing Zumwalt Class, Arleigh Burke Class, and Ticonderoga Class, are incapable of fulfilling such a role. The ships would have to be cable of independent operations, and have the capacity to incorporate new technologies including laser weapons, newly developed combat drones capable of ship to shore, ship to ship, and ASW operations, are needed. The ships would have to be capable of extended independent operations, and have substantial protection against current anti-ship weapons, and torpedoes. It seems  to me that a new class of Battle Cruisers, in effect a new, enlarged and much improved Alaska Class would be in order.

The Alaska Class was a failure in design and practice. By the time they were completed their primary mission no longer existed, and the compromises in their design ensured that they would be incapable of any real modernization that would make them effective components of a modern Navy. It was not the first or last time the US Navy, the Royal Navy, or any other Navy has design and built a lemon.

Until tomorrow,

Peace

The Vittorio Veneto Class Battleships: The Pride of Italy and Victims of Changing Technology


Vittorio Veneto and Littorio

Friends of Padre Steve’s World,

Once again I have decided to destress and not write about COVID 19, politics, or the Holocaust and instead write about an interesting, and even fascinating class of warships which have been often forgotten.

This is the first in a series of six articles on the battleships built under the provision of the Washington and London Naval Treaty limitations in the 1930s. I am not including the ships which were completed in the immediate aftermath of the Washington Treaty limitations. This series looks at the modern battleships that the World War II combatants would produce in the 1930s which saw service in the war.

Part one covers the Italian Vittorio Veneto class, Part Two the French Dunkerque and Richelieu Classes, Part Three the British King George V Class and Part Four the American North Carolina and South Dakota Classes. The thing that I find interesting about all of these ships is who inventive each Navy building them was considering treaty restraints and their own adherence to, disregarding of, or the technical issues that they faced as none had designed or built a new battleship since the end of the First World War. In the case of Italy they did not even complete their most modern design after the war, thus the building of large and fast battleships was something new to each party. Had the economic effects of the First World War been so difficult, and the following Great Influenza of 1918-1919 so devastating, all of the navies involved might have completed ships that would have influenced the next generation.

I have already published the final part which covers the German Scharnhorst Class entitled Power and Beauty the Battle Cruisers Scharnhorst and Gneisenau The German Bismarck, Japanese Yamato, British Vanguard and American Iowa Classes will be covered in a subsequent series.

Most of these ships were constructed after the expiration of the treaties, but since most of the navies at least attempted to maintain a façade of compliance with the treaty limitations, most were officially listed as complying with the treaty restrictions. The fact that nations frequently lie about their adherence to treaty limitations, is nothing new, or surprising.

The Washington Naval Treaty placed a limit on the displacement and armament of battleships. It also stipulated the tonnage of capital ships allowed for each Navy, as well as limits on the displacement of cruisers, and destroyers. The only country not effected by the treaty was Germany, which until 1935 was required to observe much stricter limitations than Great Britain, the United States, France, Italy, or Japan.

The Washington Naval Treaty led to the scrapping or cancellation of nearly all the super Dreadnoughts, and fast battleships, sometimes known as Battlecruisers of the United States, Great Britain, Japan, France, and Italy. However, its restrictions opened up the development of large aircraft carriers by the United States and Japan which each were allowed to complete two of their new battleships or Battlecruisers into aircraft carriers, specifically the IJN Akagi and Kaga, and the American USS Lexington and Saratoga.

The London Treaty continued the restrictions of the Washington Treaty which limited the displacement of new ships to 35,000 tons with the main battery being limited to 16” guns. Each of the treaty signatories as well as the Germans, who were bound by the much more stringent Treaty of Versailles restriction, endeavored to build to the limit of the treaty and if possible skirt the limitations in terms of displacement which allowed them to increase protection as well as more powerful engineering plants. The Germans, now Hitler’s Third Reich, were aided in this by a bi-lateral Naval Agreement with Britain in 1935. The treaty not only allowed them a legal way to avoid the Versailles restrictions and gain international respect.

The Royal Italian Navy, or the Regia Marina had not completed a battleship design since the Andria Doria Class which were constructed between 1912 and 1915. These ships were provided  an extensive modernization between 1937 and 1940.  The modernization allowed them to serve as first line ships throughout the war. A subsequent class the Francesco Caracciolo class was started during the First World War but no ships of the class were completed. Italy’s war debts, overall financial condition, as well as the similar situation of the French, Italy’s main rival in the Mediterranean Sea, ensured that the Regina Marina had little money for new ships or modernizing old ships during the 1920s and 1930s. Even the accession of Mussolini did little to help the Navy until the 1930s. Even then competing ideas of how to build a new Navy were present in the Italian Naval High Command. Some placed their emphasis on large numbers of battleships, others a mix of aircraft carriers, fast battleships, cruisers and destroyers, while other sought a middle ground.

However, the Italians were forced to act as in the 1930s a new naval arms race was underway in the Mediterranean. The French Navy had begun a new class of Fast Battleships, the Dunkerque class which were designed to defeat the German Deutschland class “pocket battleships” and the follow on Richelieu Class of fast battleships. Mussolini saw the new French ships as a threat to the his control of the Mediterranean, or as the Italians and their Roman ancestors called it Mare Nostrum (our Sea), and ordered the construction of a new class of battleships to help Italy achieve naval dominance in the Mediterranean.

The new ships were of a breathtaking design. They were  large, fast and heavily armed. While they were officially listed as meeting the prescribed treaty limit of 35,000 tons they actually would displace 41,177 tons standard displacement, and 45,963 tons full load. They were armed with a main battery of 9 15” L/50 guns in triple turrets. They had a secondary armament of 12 6” and 12 3.5” dual purpose guns, and a powerful light anti-aircraft battery of 20 37mm and 30 20mm anti-aircraft guns. They were capable of a top speed of 30 knots. Although they had a relatively short range of 3900 miles at 20 knots, they were formidable ships for operations in the constrained waters of the Mediterranean where they would not be required to operate at long ranges from Italian bases in Italy, Sicily, or Libya. They were well protected from shellfire, although their Pugliese torpedo defense system proved inferior to traditional designs, because it did not hold up well to direct hits, or close aboard explosions which resulted in massive flooding when hit by a torpedo or by a near miss from a heavy bomb or shell.

Their main armament though formidable was not without its flaws. The 15” guns had a very long range of 42 km or 26.6 miles and high muzzle velocity of 2900 fps. This meant that they had a long reach, however, their high muzzle velocity led to a barrel life of only about half that of their counterparts, and led to inconsistent shell fall patterns, which lessened to probability of hitting targets at long range. The guns also suffered from a slow rate of fire of only 1.3 rounds per gun a minute.

The Ships

Vittorio Veneto in 1943

The Vittorio Veneto was laid down 1934 along with her sister the Littorio, and was launched on 25 July 1937. She was commissioned on 28 April 1940, barely a month before Italy declared war on France and Britain. She would see action numerous times and give a good account of herself against the British taking part in 56 war missions. She fought at the Battle of Cape Spartivento (Teulada) where she fired 19 salvos to drive off a 7 ship British cruiser squadron in a pitched battle that also included the battleship HMS Ramillies and battle cruiser HMS Renown. In 1941 she took part in the Battle of Cape Matapan where she was damaged by an aerial torpedo after driving off a British cruiser squadron. After repairs she was back in action and on 15 June 1942 participated in the Battle of Mid-June, where she and her sister ship Littorio successfully fenced off a large British convoy from Alexandria by their mere presence at sea.  She was also the first Italian battleship equipped with radar. She surrendered with the Italian fleet to the Allies on 8 September 1943 surviving furious German air attacks. She was interred at the Great Bitter Lakes in the Suez Canal. After the war she taken as war compensation and was returned to Italy and scrapped beginning in 1948.


Littorio

Littorio (later Italia): Littorio was laid down in 1934 and launched on 22 August 1937 and commissioned on 6 May 1940.  She participated in 43 operations including the Battle of Sirte and several actions against British convoys.  Following the Battle of Mid-June she was struck by an aerial torpedo dropped by a Wellington bomber. She was repaired and upon the removal of Mussolini from power was renamed Italia and surrendered with the Italian Fleet on 8 September 1943 being damaged by a Fritz-X radio controlled bomb. With her sister the ex Vittorio Veneto, now Italia, she was interred in the Great Bitter Lake and was returned to Italy where she was decommissioned and scrapped beginning in 1948.


Roma

 Roma was laid down 18 September 1938, launched on 9 June 1940 and commissioned 14 June 1942.  Despite her addition to the fleet she was not deployed due to a fuel shortage. She sailed with the Italian Fleet to surrender on 8 June under the guise of the fleet sailing to attack the Allied invasion fleet off Salerno. The Germans discovered the ruse and the Luftwaffe launched air attacks against the Italian Fleet. Luftwaffe Dornier Do-217s armed with Fritz-X radio controlled bombs attacked the fleet as it transited the Strait of Bonafacio.


Roma exploding after being hit by Fritz-X radio guided bomb 

Roma was hit by two of the missiles the first which flooded two boiler rooms and the aft engine room.  She was hit again by a second Fritz-X which hit in the forward engine room causing catastrophicdamage. The explosions ignited the number two turret magazine blowing the turret off the ship and causing the ship to capsize and break in two. She sank, carrying 1255 of her crew including Admiral Carlo Bergamini to their death. Roma was the first ship sunk by a radio controlled bomb, the forerunner of our current air launched anti-ship missiles. In the years since, lightly constructed surface ships have not faired well against air or sea fired anti-ship missiles.


The Fritz-X Radio Guided Bomb

The fourth and final ship of the Class, Impero, was was laid down and launched, but never completed. When Italy surrendered the Germans used her incomplete hull as a target sinkinrn her. She was raised and scrapped after the war.

Impero Being Launched in 1939

The Vittorio Veneto class was a sound design and operationally successful against the Royal Navy. Her design was explored by the Soviet, Dutch, and Spanish navies in their attempts to build moderner battleships or battlecruisers, although none came to fruition. The fact that the two surviving ships, as well as the newest most modern were scrapped was a travesty as the Cold War began. Their loss left Italy with the remaining two Andrea Doria class battleships, completed in 1915 and 1916 as the battle force of the Italian Navy, until they were scrapped in the late 1950s and early 1960s.

The brave sailors of the Regina Marina who manned these fine ships should not be forgotten.

Until tomorrow,

Peace,

Power, Beauty and Tragedy at Sea: The Battlecruisers Scharnhorst & Gneisenau

Scharnhorst

Friends of Padre Steve’s World,

I was too tired last two nights to write anything. Thursday I had a long but good day at work and had to clean out much of my private email last night before I could do anything else because I was at over 90% of my email storage capacity. And it took forever to sort through it and get it down to almost 50%. Likewise, I did very little on social media. I finally caught up on my comics from the last couple of days and replied to some correspondence that I needed to do and began to work on this last night, but again found that I was too tired to complete it. So when it appeared that I wouldn’t complete it until after midnight I simply said “what the hell” and put it off until now.

This is another one of those posts to switch things up and write about a class of warships that I find fascinating, the World War II German Battlecruisers, Scharnhorst and Gneisenau. First and foremost I think that they were among the most beautiful capital ships ever built. That doesn’t mean that they didn’t have design flaws, or were superior to many other capital ships. Gneisenau’s career was cut short by Germany’s inability to protect her while in port, while Scharnhorst was the victim of an ill planned sortie under the command of an admiral who had no experience commanding large ships and who had only assumed command of her task force the day before. So if you are a Naval history or warship  buff, enjoy.

Have a great day, stay inside and if you have to go out wear a mask and keep a safe distance from others to protect you and them.

Peace,

Padre Steve+

 

The naval architects of Germany in the early 1930s designed some of the most beautiful as well as deadly warships of the Second World War.  Following Nazi Germany’s rejection of the provisions of the Treaty of Versailles the Kreigsmarine enacted building program to enlarge and modernize the German Navy.

Gneisenau refueling  from Tanker Westerwald in July 1939 

The first major units constructed were actually begun by the predecessor to the Kreigsmarine, the Reichsmarine of the Weimar Republic.  These were the Deutschland class Armored Ships, Panzerschiffe, sometimes called “Pocket Battleships” and later during the war were reclassified as Heavy Cruisers. These ships were designed to replace the old pre-Dreadnaught battleships which Germany was allowed to retain following the Treaty of  Versailles. The ships incorporated electric welds to reduce displacement, diesel engines for extended cruising range to enable them to serve as commerce raiders and a battery of six 11” guns. It was believed that as surface raiders their speed would allow them to avoid battle with all existing battleships except the three British Battlecruisers Hood, Renown, and Repulse, while being able to outgun any heavy or light cruiser they might encounter on such a mission. While they were an advance over anything in the German inventory they were outclassed by Hood, Renown and Repulse, as well as later French Dunkerque and Strasbourg. 

Gneisenau

The next and first truly capital ships built by the Kriegsmarine were the Scharnhorst and Gneisenau battleships which in reality were battle cruisers because of their light main battery of 11” guns as opposed to the 14”, 15” or 16” batteries of other nations battleships. The Hermans did. plan to rearm them with 15” guns but the war kept that from happening.

Scharnhorst before the War 

Despite the disparity in their main armament, their displacement and armor protection was comparable to other battleships of the era and their designed speed of 31.5 knots was superior to almost all other battleships of the era including the British King George V Class and the US North Carolina class.  Only the British Hood was superior to them in speed. However, their speed came at a cost, they did not have the long cruising range to make them truly effective commerce raiders because they were propelled by steam turbines which consumed large amounts of fuel. Since the Germans did not have a fleet replenishment system like the U.S. Navy, nor the secure network of worldwide bases of the Royal Navy, they could only operate in the Northern Atlantic or Arctic for limited amounts of time. If damaged there were few safe harbors for them which had the capability of repairing them without them being exposed to allied bombers.

Gneisenau Main Battery

As built they displaced 31,000 toms, however at full combat load they both weighed in at nearly 38,000 tons and were 772 feet long.  They had an armor belt that was nearly 14 inches thick.  Armed with a main battery of nine 11” guns and a secondary armament of twelve 5.9 inch guns they also mounted a powerful for the time anti- aircraft battery of fourteen 4.1 inch guns, 16 37mm and 16 20mm anti-aircraft cannons.  Additionally they mounted six 21” torpedo tubes and carried three Arado 196 A3 scout planes.  The main battery was eventually to be replaced by six 15” guns but this never occurred although Gneisenau was taken in hand after being damaged in Operation Cerberus to mount the new weapons but the conversion was never completed.

Scharnhorst in Action Against HMS Glorious

Scharnhorst was laid down on 15 June 1935 and launched 3 October 1936. She was commissioned 7 January 1939.  Her sister Gneisenau was laid down 6 May 1935, launched 8 December 1936 and commissioned 21 May 1938.  Upon the commencement of the Second World War the two sisters began a reign of destruction on British shipping in the North Atlantic. On 23 November 1939 they sank the Armed Merchant Cruiser HMS Rawalpindi while on patrol near the Faroe Islands.

During Operation Weserübung the pair surprised sank the aircraft carrier HMS Glorious and her two escorting destroyers HMS Ardent and Acasta on 7 June 1940. It was the only time a Fleet carrier was caught and sunk by battleships during the war. However, Scharnhorst was hit by a torpedo from Acasta which led to her being withdrawn to Trondheim, for temporary repairs before retiring to Kiel for permanent repairs.

Scharnhorst during Operation Berlin and being Refueled during the Operation

From January to March 1941 they conducted Operation Berlin under the command of Admiral Gunther Lütjens against British merchant shipping in the North Atlantic sinking 22 ships before returning to base. During the action the task force encountered the British Battleships HMS Ramillies and HMS Malaya escorting different convoys which Lütjens refused to engage. After sinking ships from another convoy they encountered HMS King George V and HMS Rodney which they escaped using their superior speed, but by now, Lütjens realize that the danger of continuing the outweighed the potential success and headed for repairs in the port Brest, in occupied France.

While in Brest Scharnhorst needed repairs to a superheater for her boilers, while Gneisenau was damaged during a British air raid and were unable to deploy with Bismarck and Prinz Eugen for Operation Rheinübung, during which Bismarck sank HMS Hood, but was damaged by a 14” shell from HMS Prince of Wales which cut the fuel line from the ship’s forward fuel tanks. Lütjens decided to cut the mission short and escape to Brest, but was damaged by an aerial torpedo from a Swordfish torpedo bomber flying from HMS Ark Royal which wrecked her steering gear and allowed HMS King George V, HMS Rodney, as well as cruisers and destroyers to catch and sink her on May 27th. Prinz Eugen returned safely to Brest to join the Battlecruisers.

While at Brest Gneisenau was again bombed and torpedoed requiring extensive repairs.  Due to the exposed location of the port, the German high command decided to return the ships to Germany along with the Heavy Cruiser Prinz Eugen.  Commanded by Vice Admiral Otto Ciliax,  Operation Cerberus took place from 11-13 February 1942. It involved the Battlecruisers and Prinz Eugen, accompanied by destroyers, E-Boats, and R-Boats. The force was protected heavy Luftwaffe fighter cover, Code named Operation Donnerkeil the air operation was commanded by the legendary Luftwaffe fighter ace, General Adolf  Galland. 

The dash up the English Channel, was unsuccessfully contested by the Royal Air Force and Royal Navy. The German ships successfully broke through the Channel in broad daylight and protected itself from being damaged by aircraft, motor torpedo boats, destroyers, and shore batteries. Once clear of the channel and headed for home both Scharnhorst and Gneisenau struck mines which caused various amounts of damage, but both got through to Kiel.

The success of the daylight passage through the English Channel shocked and infuriated the British public. The Times of London published an editorial on 14 February which fumed:

Vice Admiral Ciliax has succeeded where the Duke of Medina Sidonia failed. Nothing more mortifying to the pride of our sea-power has happened since the seventeenth century. […] It spelled the end of the Royal Navy legend that in wartime no enemy battle fleet could pass through what we proudly call the English Channel.

Despite the fact that then Operation was successful, the high command of the German Navy Their breakthrough was an embarrassment to the Royal Navy and Royal Air Force. The high Command of the German Navy considered it a tactical victory but a strategic defeat, for it had traded a base, albeit exposed from which it could conduct offensive operations, to the defense of Norway, a mission of dubious value at best.

                                    Gneisenau after being Bombed in Floating Dry Dock

While undergoing repairs in a floating dry dock at Kiel Gneisenau was heavily damaged by the Royal Air Force on the night of 26-27 February. The damage was such that the Kriegsmarine High Command decided to elongate her damaged bow section and rearmament to replace her main battery with 15” guns. Once seaworthy she steamed to the port of Gotenhafen for full repairs and rearmament. Although some work was completed the conversion was halted by Hitler who was infuriated by the failure of a German Task Force at the Battle of the Barents Sea, 30-31 December 1942. Hitler fired Grand Admiral Erich Raeder, and and gave an order to scrap what remained of the German surface fleet and concentrate on the U-Boat war. Admiral Karl Donitz prevented the scrapping of the fleet, but most ships were laid up and their crews reassigned to provide crews for U-Boats. Gneisenau was disarmed with her 11” and twin 5.9” removed and installed along the Atlantic Wall. One triple 11” turret, either Bruno or Dora was installed as part of a coastal defense battery in Norway. The battery was taken over by the Norwegians after liberation and remained in commission as Austrått Fort until 1968. Since then it has become a well preserved museum.

When the Red Army approached Gotenhafen her remaining crew moved her to the harbor entrance and sank her as a block ship on 27 March 1945.  Following the war she was raised by the Poles and scrapped in 1951.

Scharnhorst was repaired following Operation Cerberes and in March 1943 was transferred to Norway where along with Tirpitz, Admiral Scheer, Lutzow (the former Deutschland), Admiral Hipper and Prinz Eugen she became part of a “fleet in being” poised to strike the Allied convoys bound for Russia. On Christmas Day 1943 under the command of Rear Admiral Erich Bey the Scharnhorst set sail with several destroyers undertook Operation Ostfront and the ensuing battle became known as the Battle of North Cape. The mission was an attack on two Russia bound convoys. But the orders were intercepted and decoded by the British. Admiral Bruce Fraser planned a trap to intercept and neutralize Scharnhorst. 

Once Scharnhorst sailed the battleship HMS Duke of York, four cruisers and a number of destroyers as she closed on the convoy. However, due to the sea conditions Bey detached his escorting destroyers and ordered them to return to port.  Duke of York and her supporting cruisers and destroyers engaged Scharnhorst. Bey now realized he had no chance of destroying the convoy and attempted to escape.  However, Scharnhorst was damaged and her speed and maneuvering capabilities impaired.  Now virtually defenseless and surrounded the great ship was sunk with the loss of all but 36 of her 1968 man crew. Her wreck was discovered 3 October 2000 some 70 miles north of North Cape Norway.

Survivors of Scharnhorst debark in England 

Thus ended the careers of two of the most beautiful battleships ships to grace the seas. Though their  careers were short they both survived frequent heavy battle damage to return and fight again.  Perhaps  their greatest weakness was the inability of the German Navy to provide them adequate escorts at sea, and the inability of the Luftwaffe to protect them against air strikes while in port. But ultimately their great weakness was the poor naval strategy employed by Hitler and Raeder at the beginning of the war which ensured their destruction. Of the major German surface units only the Pocket Battleships we’re capable of long range commerce raiding operations. The short range of the other heavy German ships, their reliance on steam turbines rather than Diesel engines, lack of air and surface support at sea, and secure overseas bases that that could operate doomed all of them to failure, and resulted in the deaths of far too many brave sailors, fighting for their country in an unrighteousness and evil cause.

The Pinnacle of Naval Superiority or Obsolescence: The Battle Cruisers of 1920 and the Aircraft Carriers of 2020

Artists Depiction of G3 Battlecruiser 

Friends of Padre Steve’s World,

The next few days I will be reflecting on the old year and the coming new year, but tonight I decided to tweak and republish an article from about four years ago dealing with the battle cruisers being built by Great Britain, Japan, and the United States after the First World War. They represented the pinnacle of naval design for their era and would have been far superior to their adversaries had technology and war remained static. As Admiral Ernest King noted:

“Nothing remains static in war or military weapons, and it is consequently often dangerous to rely on courses suggested by apparent similarities in the past.”

As the First World War ended a new Naval Race was heating up. The United States had announced its intention during the war to build a navy second to none while Imperial Japan was making plans for a fleet that would give it superiority in the Western Pacific. The British, though still be far the largest naval power in the world were burdened by the massive costs of war and empire, but also seeking to maintain their naval dominance and to that end they were in the process of building a class of massive super-Dreadnought battleships, and Battle Cruisers.

Much of each powers actions in the coming years would be based on internal politics, foreign policy, and the simple economics of how much each power could afford to spend on their militaries after such a costly war. The result was the Washington Naval Treaty of 1922 which limited the signatories to specific numbers, tonnage, and armaments each Navy would be allowed. Do to those reasons the massive Battle Cruisers planned by Britain, the United States and Japan were canceled. The Japanese and Americans would choose to convert two of their incomplete ships to aircraft carriers, while the British would convert the already completed ships of the Courageous Class battlecruisers (Courageous, Glorious, and Furious) into aircraft carriers as though none of the G3 ships had been laid down.

The ships known as the G3 battle cruisers were first designed by the British Royal Navy as a compliment to the all big gun Dreadnought battleships. The Battle Cruiser concept was for a ship of roughly the same size and firepower as a Battleship, but sacrificed armor protection for greater speed, endurance and range.  The United States and Japan joined in the Battle Cruiser race before and during the war. However, Britain the United States had concentrated on building battleships during the war but following the war began to design and build its own classes of massive battle cruisers.

HMS Invincible Blowing Up at Jutland 

During the war the weaknesses of the battlecruisers as a type were exposed during the Battle of Jutland where three British Battle Cruisers, the HMS InvincibleHMS Indefatigable and HMS Queen Mary blew up with the loss of most of their crews; of the 3311 officers and sailors on the ships only 26 survived. The HMS Lion was almost lost in a similar manner but the heroic actions of her crew saved her from her sisters fate. The British ships had glaring deficiencies in armor protection and the arrangement of their ammunition magazines and hoists which certainly contributed to their loss. Their German counterparts on the other hand proved much tougher and though all sustained heavy damage while engaging British Battleships and Battle Cruisers, only one the Lützow was lost. She absorbed over 30 hits from large caliber shells and only lost 128 crew members. However, though a battle cruiser Lützow, and other German battle cruisers wer designed for relatively short range operations which meant they neither sacrificed armor protection, speed, or firepower as did the British ships which were designed for missions far and wide, needing more displacement for fuel and crew supplies, often sacrificing armor protection in order to maintain their high speed capabilities.

HMS Hood

As the war progressed other Battle Cruisers were built, the British launched the HMS Repulse and HMS Renown and completed the HMS Hood shortly after the war was over. The Japanese built the four ship Kongo class from a British design, the first of which, the Kongo was completed in a British yard, the others Haruna, Hiei, and Kirishima were built in Japanese yards. The Kongo Class would prove to be the workhorses of the Battle Force of the Imperial Japanese Navy, all seeing significant combat action.

As the powers embarked on the next Naval Race planners and naval architects designed ships of massive firepower, better protection and higher range and speed. All would have been better classed as Fast Battleships, a better description of the Kongo Class or the Hood than previous ships.

The British designed and funded the G3 class in 1921, while the Japanese began work on the Amagi Class, and the United States the Lexington Class. However the construction and completion of these ships as Battle Cruisers was prevented by the Washington Naval Treaty.

invincible 490

The treaty, which was ratified in 1922 limited the United States and Great Britain to a maximum of 525,000 tons in their battle ship fleets and 125,000 tons in aircraft carriers.  The Japanese agreed to a limit of 315,000 tons and the French and Italians 175,000 tons each. Tonnage for battleships was limited to a maximum of 35,000 tons with a limitation on guns size to 16 inches.  Since the bulk of the ships planned or being built by the US and Japan exceeded those limits they would be effected more than the British whose post war shipbuilding program had not begun in earnest, in fact the G3 Class had just been approved for construction and there is no proof that construction had begun on any of the ships.

The G3 class would have comprised four ships and been similar to the N3 Class Battleships. They were very well balanced ships and would have mounted nine 16” guns in three turrets on a displacement of 49,200 tons and deep load of 54,774 tons. They had an all or nothing protection plan meaning that the armored belt was concentrated in vital areas around the armored citadel, conning tower, turrets and magazines and engineering spaces. Their armor belt would have ranged from 12-14 inches, deck armor from 3-8 inches, conning tower 8 inches, barbettes 11-14 inches, turrets 13-17 inches and bulkheads 10-12 inches. Their propulsion system of 20 small tube boilers powering 4 geared steam turbines connected to 4 propeller shafts would have produced 160,000 shp with a designed speed of 32 knots.

The four ships, none of which were named were ordered between October and November of 1921. Their construction was suspended on November 18th 1921 and they and the N3 Battleships were cancelled in February 1922 due to the limitations of the Washington Naval Treaty. Many concepts of their design were incorporated in the Nelson Class battleships which were a compromise design built to stay within the limits of the treaty.

Amagi Class as Designed, Akagi as Completed (below)

The four planned Japanese Amagi Class ships would have mounted ten 16” guns on a displacement of 47,000 tons at full load. Their propulsion system 19 Kampon boilers powering four Gihon turbines would have given them a maximum speed of 30 knots, They would have had less protection than the G3 ships being more of a traditional Battle Cruiser design. As a result of the Washington Naval Treaty the Japanese elected to convert two of the ships, the Amagi and Akagi to aircraft carriers. Amagi was destroyed on the ways during the great Tokyo earthquake and Akagi was completed as a carrier. The other two vessels were scrapped on the ways. To replace Amagi the Imperial Navy selected the incomplete Tosa Class battleship Kaga. 

Lexington_battlecruiser_conversion_models

The United States Navy planned the six ship Lexington Class. These ships would have mounted eight 16” guns on a ship measuring 874 feet long and 105 feet in beam, displacing 43,254 tons at full load, or nearly the size of the Iowa Class battleships. They would have had a maximum speed of 33 knots being powered by 16 boilers which drove 4 GE electric turbines producing 180,000 shaft horse power. Theirs was a massive engineering plant and while the class did not have as heavy armor protection as either the G3 or Amagi classes, they were superior to them in speed as well as endurance. Upon ratification of the Washington Naval Treaty four of the six ships were cancelled and the remaining two, the Lexington and Saratoga competed as aircraft carriers.  Had any of the ships been completed as Battle Cruisers it is likely due to their speed that they would have operated primarily with the the carriers that the US Navy built during the 1930s.

g416531

One can only speculate what the navies of World War II would have looked like had the Washington and the subsequent London Naval Treaties not been ratified. One can also only imagine how the war at sea would have been different had the ships completed as carriers been completed as Battle Cruisers. It is certain had the Royal Navy, the Imperial Japanese Navy, and the United States Navy Not Converter These ships, that Naval Aviation would have take years, or maybe more than decades to reach its potential.

However that was not to be, of the planned 14 ships of these three classes only three were completed, all as aircraft carriers, ships that helped to forge the future of naval operations and warfare for nearly a century. Thus the uncompleted ships are an interesting footnote in naval history yet have their own mystique.

                 HMS Queen Elizabeth 

Yet nothing remains static. The carriers have ruled the waves since December 7th 1941. But the massive aircraft carriers which have ruled the seas since the Second World War are not necessarily invincible and depending on how technology progresses could be heading into obsolescence, and may end up serving in support roles or being paid off. Yet that being said the United States is continuing to construct carriers of the Ford Class, the British the Queen Elizabeth Class, while the Chinese and Indian Navies pursue the development of new super carriers, while the French Navy operates the CVN Charles De Gaulle.  

But with the development of more and more relatively cheap, long range, and maneuverable land based anti-ship missile systems, and the capabilities of modern submarines we have to ask the legitimate question, is the aircraft carrier’s reign of the seas in jeopardy? This is a good question, but not the only one because since World War II there have been no carrier versus carrier engagements on the high seas. There are some places that are outside the range of land based anti-ship weapons, although submarines may prove a problem for surface forces to deal with, and for carriers their survival.

But since there have been no carrier versus carrier actions since the Second World War it would be interesting to see how the current carriers now operational or being developed would fare against each other if such an encounter occurred. It would be a test of air wings, ship design, and the protective capabilities of their escorts, as well as the cyber realm, on, above, and below the surface. Until such an engagement occurred all opinions, even those done in computer simulations are at best guesses as most of the weapons systems have never been tried in actual combat against peer competitors. Thus, like the carriers and their escorts designed before the Second World War, they will have to be tested in combat to see if they are still relevant in their designed role, or if they will be relegated to support roles which could be done by less costly alternatives such as the LHA/LHD type ships of the United States, France, Japan, and South Korea, or the the Sea Control Ship derivations in other smaller Navies in Europe and Asia.

Perhaps to meet some missions smaller and cheaper carriers will be developed, or existing platforms modified to carry more capable aircraft as the Japanese are doing with their Izumo and Hyuga Class “Helicopter Destroyers,” and the South Koreans are doing with their two Dokto Class LPH (Landing Platform Helicoptor) both of which may soon begin to operate the F35B fighter aircraft purchased from the United States, the same aircraft with will operate from United States Navy LHAs and LHDs as well as the British Queen Elizabeth Class. 

JMSDF “Helicopter Destroyer” Kaga 

Thus, one might wonder if the large new aircraft carriers currently being built by the United States, Britain, China, India, and other nations will also be displaced by advancing technology as were the battlecrusiers of the 1920s. It is a question that must be asked. There are certainly arguments for them, but what would the effect be on the United States Navy if one of the Nimitz or Ford Class carriers was sunk by the Chinese, or evening the Iranians? My guess is that it would be the same kind of shock that hit the Royal Navy after Jutland, and the U.S. Navy after Pearl Harbor.

I still believe in the aircraft carrier, as a weapon of deterrence, support of operations ashore, and against enemy ships on the high seas. But eight decades is a long run for any weapons system, and it is possible that despite the major power’s investment in carriers, that their reign may be coming to an end, at the same time it may be too early to count out the Super Carriers. Perhaps their mission will be modified to support smaller ships in sea control missions and reserved for potential combat with countries which have no answer to them, or against similar platforms in open ocean battles.

USS Gerald R. Ford 

I believe that the future has not been decided in relation to the aircraft carrier and much of that will have to do with how the operators of such vessels adapt to a changing world with many more threats, in order to maximize their capabilities while minimizing the dangers to such expensive national security assets. This is the aspect of war and national security that is within the control of human beings. I think of Admiral Arleigh Burke’s words at times like this:

“For in this modern world, the instruments of warfare are not solely for waging war. Far more importantly, they are the means for controlling peace. Naval officers must therefore understand not only how to fight a war, but how to use the tremendous power which they operate to sustain a world of liberty and justice, without unleashing the powerful instruments of destruction and chaos that they have at their command.”

he other possibility is that the navies that operate them decide that they are too expensive, and that their vulnerabilities outweigh their capabilities. This was the case in the 1920s with the battlecruisers then under construction.

Until tomorrow,

Peace

Sinking Leviathan: The Death of the Bismarck

FinalBattle

Friends of Padre Steve’s World

This is the final part of my rendition of the great naval tragedy in three acts involving the German Battleship Bismarck. The first part was the sinking of the legendary and graceful pride of the Royal Navy, the Battle Cruiser Hood. The second part was the seemingly futile hunt and chase of the Bismarck by units of the British Home Fleet. What seemed hopeless changed when hours from the protection of night Bismarck was discovered and then torpedoed in a last ditch effort by Swordfish torpedo planes from the HMS Ark Royal. Today, the final act, the sinking of the Bismarck. 

I have written about this before and this is an edited version of that article. As I have mentioned before I have long been fascinated with this naval tragedy. I call it that because I have served at sea and in combat ashore; and because I understand that amid all the technology and weaponry that ultimately it is the men who suffer the terrors of war, and who suffer and die who matter. Soldiers, Sailors, Marines and Airmen seldom get a choice in the wars that the leaders of their nations send them to fight. Thus for me, even the Sailors of the Bismarck, the pride of Adolf Hitler’s Kriegsmarine are as much victims of war as the British Sailors aboard the HMS Hood. 

Peace

The torpedo from the Swordfish from the HMS Ark Royal that struck the Bismarck in her stern, jammed her rudders and wrecked her steering gear at last light on May 26th 1941, doomed the remarkable ship and her crew. It was an astounding turn of events, as just minutes before the hit both the Germans and the British were expecting Bismarck to reach safety of German occupied ports in France to fight again.

Just days before Bismarck had sunk the legendary British Battle Cruiser HMS Hood in minutes and had she persisted in her attack could have sunk the new Battleship HMS Prince of Wales. Instead, Vice Admiral Gunther Lutjens in command of the Bismarck and her consort the Heavy Cruiser Prinz Eugen decided to break off contact and make for safety in the French port of Brest.

Bismarck slipped her pursuers and allowed Prinz Eugen to escape. It seemed that nothing that the British could do would stop her from gaining the safety of the French port and with it the knowledge that she had sunk the most powerful ship in the Royal Navy and gotten away. Then out of nowhere Bismarck was spotted by a Royal Air Force Coastal Command PBY Catalina seaplane piloted by an American Naval Officer. Hours later a relatively small and slow torpedo dropped from an obsolescent Swordfish torpedo bomber, a “Stringbag” hit the Bismarck in in her stern, wrecking her rudders and steering gear. Remarkably it was perhaps the only place that such a torpedo could have changed the developing narrative of a great German naval victory into defeat.

As darkness fell on May 26th, Bismarck, unable to steer towards Brest due to her damage and the following seas steered toward the oncoming British armada at a reduced speed. Her crew, now exhausted from countless hours on watch and at their battle stations knew that they were doomed.

Despite this the officers and sailors aboard Bismarck still labored trying in vain for a way to repair and save their their ship. As Bismarck’s engineers and damage control personnel sought at way to repair the damage on that dark night Royal Navy destroyers under the command of Captain Phillip Vian harassed her, closing to fire torpedoes and keep the exhausted crew of the mighty German ship engaged at their battle stations throughout the long night. Knowing that the end was near the Captain of the Bismarck ordered the contents of the ship’s store to be given to crew members.

As light broke on the morning of May 27th the remaining heavy units from the Home Fleet which still had enough fuel in their tanks to continue the action, the Battleships HMS King George V and HMS Rodney along with the Heavy Cruisers HMS Norfolk and HMS Dorsetshire which had broke from its convoy escort duties on the 26th closed in for the kill. Norfolk had been in on the hunt since the beginning when she and her sister ship the HMS Suffolk had discovered Bismarck and Prinz Eugen as the transited the Denmark Strait on the night of May 23rd and 24th.

Warily the British ships closed the crippled but still powerful German battleship. At 0847 Admiral Tovey ordered British Battleships to open fire on Bismarck. The crippled German ship replied with accurate salvos and straddled Rodney. However, the British shells hammered the Bismarck. 16” shells from Rodney destroyed the command center of Bismarck and her main fire control stations. Within 30 minutes the mighty guns of the Bismarck which had sunk the Hooddays before were silenced.  With no opposition from the stricken German ship the British battleships and cruisers pounded Bismarck from point blank range with 16”, 14”, 8” and 6” shells as well as torpedoes.

The end of the Bismarck

The British ships scored at least 400 hits on Bismarck and though they had silenced her and reduced the German ship to smoking ruins, the Bismarck remained afloat, defying her attackers. She was burning and certainly doomed but undaunted. The British battlewagons continued to pound Bismarck at point blank range, until finally, with their adversary obviously doomed and their own fuel supplies were dangerously low.  Admiral Tovey then ordered his battleships to break off the action. As he did this the British cruisers continued to fire their guns and torpedoes at the blazing helpless ship.

Bismarck Survivors being hauled aboard Dorsetshire

The Bismarck’s First Officer, Fregattenkapitan (Commander) Hans Oels ordered her Chief Engineer Korvettenkapitan (Lieutenant Commander) Gerhard Junack to prepare the ship for scuttling and ordered the crew to abandon ship. The watertight doors were opened by Bismarck’s damage control teams and engineers as the scuttling charges fired at about the same time as HMS Dorsetshire launched her torpedoes at Bismarck. 1039 the Bismarck slipped beneath the waves. To this day those who claim the Bismarck sank because her crew scuttled her, and those who believe the the fish fired by Dorsetshire decided the fate of the ship, but truthfully it doesn’t matter. No matter what happened Bismarck was going to sink and no German forces could save her, or her crew.

HMS Dorsetshire 1941

As the great ship slipped beneath the waves into the depths of the North Atlantic, hundreds of survivors bobbed about in the cold Atlantic waters. Of these men, 110 were rescued by British ships, mostly by Dorchester. Then lookouts aboard the cruiser spotted the periscope of a U-Boat, and the British ships broke off their rescue operations leaving hundreds more survivors to die of exposure or their wounds in the Atlantic. In a cruel twist of fate, the U-Boat they believed they spotted had expended all of its torpedoes and was not a threat to them. A few more of the Bismarck’s survivors were rescued later by German ships or U-boats, but about 2200 German sailors went down with their ship or died awaiting rescue that never came. When it was all over just 2 officers and 113 men survived the sinking of the Bismarck, combined with the three men who survived the sinking of the Hood nearly 3700 British and German Sailors perished.

Subsequent investigations of the wreck of the Bismarck would show that all the British shells and torpedoes did not sink the Bismarck, and that it was indeed the scuttling charges that sent the mighty ship to the bottom of the Atlantic. But even had she not been scuttled, she was doomed, and the damage that she had sustained would have sent her to the bottom within 12 to 24 hours had Commander Oels not ordered Lieutenant Commander Junack to scuttle the ship.

Within a year the Ark Royal, Prince of Wales, and Dorsetshire would also lie at the bottom of the seas. Prince of Wales along the HMS Repulse was sunk by Japanese land based bombers off Malaya in 1941, Dorsetshire was sunk near Ceylon by Japanese Carrier aircraft in April 1942, and Ark Royal was torpedoed by the U-Boat U-81 in November 1941 not far from Gibraltar. Of the destroyers that harassed Bismarck the night before her sinking only one, the Polish Destroyer ORP Piorun would survive the war.

The tragedy of mission of the Bismarck is that nearly 3700 sailors died aboard the two mightiest ships in the world, and while legendary the losses of the two ships did not materially alter the course of the war. Hood’s loss though tragic did not alter the strategic equation as more new battleships of the King George V class entered service. Likewise the surfing German capital ships were harassed by RAF bomber sorties and attacks by the Royal Navy’s Fleet Air Arm. With few exceptions these ships remained confined to ports in France, Germany or Norway and slipped into irrelevance as the war progressed as the German U-Boat force took the lead in the Battle of the Atlantic.

As an officer who has served at sea on a cruiser at war which came within minutes of a surface engagement with Iranian Revolutionary Guard patrol boats in the Northern Arabian Gulf in 2002 I have often wondered what would happened in the event of an engagement that seriously damaged or sank our ship. Thus I have a profound sense of empathy for the sailors of both sides who perished aboard the Hood and the Bismarck in the fateful days of May 1941.

I hope that no more brave sailors will have to die this way, but I know from what history teaches that tragedies like this will happen again.

String Bags vs. The German Leviathan: The Crippling Of the Battleship Bismarck

Friends of Padre Steve’s World

A couple of days ago I reposted an article about the sinking of the HMS Hood by the German Battleship Bismarck. The story of the Bismarck is an epic saga of naval warfare and history. It is tragedy played out as if scripted by a playwright in three parts. The first was the sinking of the illustrious “Mighty” Hood by the Bismarck on May 24th 1941. 

The second, which I deal with today, was the pursuit and search for Bismarck by the British Home Fleet and the desperate attempt of the British to find a way, any way, to slow Bismarck down and bring her to battle, before she could return to the safety of Nazi occupied France.  The final chance to stop the mighty German Leviathan came as night fell on May 26th. 

I hope you appreciate the heroism of the men who flew the hopelessly obsolete aircraft who dealt the blow which crippled Bismarck. This is a re-write of past articles and I will post the final article about the sinking of the Bismarck tomorrow. 

There is one other thing to mention. I cannot imagine what it would have been to be a crewman on the Bismarck, knowing that nightfall would bring them safely unter the protection of the Luftwaffe, and then discover that there was no escape from death and destruction.

On May 24th 1941 the German Battleship Bismarck had sunk the celebrated Battlecruiser HMS Hood in the Denmark Strait and had seriously damaged the new Battleship HMS Prince of Wales. The news of the disaster stunned the Royal Navy. Fighting a war on multiple fronts and now standing alone against Hitler’s Germany the British deployed every warship available to find and sink Bismarck.

On the evening of the 24th of May Bismarck was being shadowed by the heavy cruisers HMS Norfolk and HMS Suffolk. To the east the ships of the Home Fleet, Britain’s last line of defense under the command Admiral John Tovey was making the fastest speed to intercept the Bismarck.  Far to the southeast, Vice Admiral James Sommerville’s  “Force H” comprised of the carrier HMS Ark Royal, the fast but elderly battlecruiser HMS Renown, and the light cruiser HMS Sheffield were ordered to leave the vital convoy which there were escorting and proceed to the northwest to join the hunt for the German battleship.

With Bismarck loose the North Atlantic Convoys on which Britain depended for her survival were vulnerable. The previous year the commander of the Bismarck task force Admiral Günther Lütjens with the Battlecruisers Scharnhorst and Gneisenau had wreaked havoc on the convoys. Now of Britain was on edge with the news of Bismarck’s break out into the Atlantic. Churchill was furious with the Navy when the Mighty Hood, the largest and most powerful ship in the Royal Navy destroyed with the loss of all but three crew members. Now every effort was directed to find and sink the Bismarck.

Accompanying the Home Fleet was the brand new Aircraft Carrier HMS Victorious with 825 Naval Air Squadron embarked under the command of LCDR Eugene Esmond. The squadron, like many in the Fleet Air Arm was equipped with Fairy Swordfish Torpedo Bombers. The squadron had seen action aboard other carriers in the North Atlantic, the Norway Campaign and in the Mediterranean before being assigned to the Victorious. On the night of 24 May 1941, in foul North Atlantic weather the Victorious launched nine Swordfish from a range of 120 miles in a desperate attempt to slow the Bismarck down. Esmond’s squadron scored one hit amidships on the Bismarck which did no serious damage.

780px-Swordfish_on_HMS_Victorious_before_strike_on_Bismarck

825 Squadron Swordfish on HMS Victorious

About 6 hours after the attack by Victorious’s Swordfish, Bismarck shook her pursuers and disappeared into the mists of the North Atlantic, while her consort, the Heavy Cruiser Prinz Eugen escaped to the northwest in order to conduct independent raiding operations. Not knowing the location or course of the Bismarck the Royal Navy frantically searched for the German Leviathan. Most of the ships nearest to Bismarck’s last reported position were low on fuel and others seemed too far away to be of any importance in the search.

However the British were able to intercept and decode some German communications which indicated that Lütjens had orders to steam to Brest, in German occupied France for repairs.

Though the British believed that the Bismarck could be headed toward Brest they could not be sure, as each hour passed the chances of finding and bringing Bismarck to battle diminished. For nearly 36 hours the British searched in vain for the Bismarck, and for much of the 25th Tovey’s squadron was searching in the wrong direction. Then at 1030 on the 26th of May their luck changed.

Likewise the crew of the Bismarck believed with every hour that they would soon be under the protection of Herman Goering’s Luftwaffe and safely in France, but the good fortune of the British was the worst thing that could happen to the 2200 men aboard Bismarck.

On that morning a Royal Air Force Coastal Command PBY Catalina co-piloted by US Navy Ensign Leonard Smith found the Bismarck. Once Smith transmitted Bismarck’s location every available ship converged on her location but unless something could be done to slow the German down the chances bringing her to battle diminished by the hour.

The only heavy forces close enough to successfully engage Bismarck, Tovey’s battleships HMS King George V and HMS Rodney were over 100 miles behind Bismarck, too far away unless Bismarck changed course or could be slowed down. Somerville’s Force H to the south did not have the combat power to survive a surface engagement with the Bismarck should they encounter the Bismarck without the support of other heavy fleet units. Even so Sommerville was willing to risk the Renown in a suicidal action to bring Bismarck to battle if it would allow Tovey to catch her before she could escape. Desperation was the order of the day for both sides.

The situation was desperate, if Bismarck could not be slowed down she would be in range of heavy Luftwaffe Air support as well as support from U-Boats and destroyers based in France. Unless something akin to a miracle occurred Bismarck would join the Scharnhorst and Gneisenau in Brest and with the addition of Bismarck’s sister-ship Tirpitz form a surface squadron strong enough to devastate British shipping in the Atlantic.

Ark Royal’s aircraft were the last hope of slowing down Bismarck before she could effect her escape and emerge from the Atlantic after having dealt the Royal Navy a devastating blow.

The strike aircraft available on Ark Royal were the most unlikely aircraft imaginable to successfully carry out such a mission. Ark Royal’s 820 Squadron, like Victorious’ 824 Squadron was equipped with Fairy Swordfish Mk 1 Torpedo Bombers. These were biplanes with their crew compartment exposed to the weather.

Introduced to the Navy in 1936 the aircraft was an antique compared with most aircraft of its day. Likewise the Mark XII 18” torpedo carried by the aircraft was smaller or slower and equipped with a less powerful warhead than comparable torpedoes used by other navies. Despite their limitations the venerable Swordfish had performed admirably during the early part of the war sinking or damaging three Italian battleships at Taranto in November 1940. Their success against the Italians at Taranto gave inspiration to the Japanese for their attack against the U.S. Pacific Fleet at Pearl Harbor the following year. But now, in the face of foul weather and a powerful opponent the Swordfish were all the Royal Navy had left to stop Bismarck before she could make her escape.

Bismarck steering erratically after the torpedo hit to her stern

With that in mind  Sommerville in sent his light cruiser, the  HMS Sheffield ahead to shadow Bismarck while Ark Royal closed in to launch her Swordfish against Bismarck. The first wave of aircraft strike, unaware Sheffield was near Bismarck mistakenly attacked the British cruiser. Thankfully, the new design magnetic detonators failed to detonate the torpedoes saving Sheffield from destruction. With little daylight left the aircraft returned to Ark Royal where they rearmed with torpedoes equipped with contact fuzes and refueled by flight deck crew laboring in rain and 50 knot winds blowing across the carrier’s flight deck. Just before 8 p.m. 15 Swordfish of 820 Squadron took off for what they knew was the very last chance to attack Bismarck before night fell. If they failed Bismarck would most certainly escape.

As darkness began to fall the 15 Swordfish from 820 Squadron descended through the clouds to attack the German ship. Just fifteen obsolete aircraft and thirty men attacking the most powerful warship afloat. They dispersed and attacked from all points of the compass. Bismarck twisted and turned and fired all of her guns at the attacking aircraft. The Germans fired with every weapon available, even the 15″ guns of her main battery, which she fired her into the ocean ahead of the Swordfish. It appeared for a moment that the Bismarck had successfully avoided serious damage. All but two torpedoes missed.  One torpedo struck the German midships and barely dented her massive armor. However a second torpedo, launched by a Swordfish piloted by Lieutenant John Moffat hit Bismarck in her weakly armored stern. The target angle from the aircraft to Bismarck was poor and those aboard the battleship who saw the torpedo approach believed that it was certain to miss, but it hit.

The hit jammed Bismarck’s port rudder at a 12 degree angle, and destroyed her steering gear. Repair crews and divers were dispatched but the weather was such that German damage control teams could not repair her steering gear. Bismarck now steamed in circles, unable to maneuver. This enabled Tovey with King George VRodney, the heavy cruisers Norfolk and Dorchester, as well as a number of destroyers to catch up with the elusive German battleship.

The attacks of the antiquated Swordfish on the Bismarck achieved results that no one in the Royal Navy expected. When reports indicated that Bismarck had reversed course following the torpedo attack Tovey could not believe them. It was only when lookouts aboard Sheffield confirmed the reports from the Swordfish that Tovey realized that Bismarck must have been damaged and was unable to maneuver.

It was a dramatic and unexpected turn of events. The German crew sank into gloom as the night went on and they dealt with torpedo attacks from the British Destroyers as Tovey’s battleships moved in for the kill.

Nothing Remains Static: The Never Built G3, Amagi, and Lexington Class Battle Cruisers

Artists Depiction of G3 Battlecruiser 

Friends of Padre Steve’s World,

This weekend I will be reflecting on the old year and the coming new year, but tonight I decided to tweak and republish an article from about four years ago dealing with the battle cruisers being built by Great Britain, Japan, and the United States after the First World War. They represented the pinnacle of naval design for their era and would have been far superior to their adversaries had technology and war remained static. As Admiral Ernest King noted:

“Nothing remains static in war or military weapons, and it is consequently often dangerous to rely on courses suggested by apparent similarities in the past.”

As the First World War ended a new Naval Race was heating up. The United States had announced its intention during the war to build a navy second to none while Imperial Japan was making plans for a fleet that would give it superiority in the Western Pacific. The British, though still be far the largest naval power in the world were burdened by the massive costs of war and empire, but also seeking to maintain their naval dominance and to that end they were in the process of building a class of massive super-Dreadnought battleships, and Battle Cruisers.

The ships known as battle cruisers were first built by the British Royal Navy as a compliment to the all big gun Dreadnought battleships. The Battle Cruiser concept was for a ship of roughly the same size and firepower as a Battleship but sacrificing protection for greater speed, endurance and range.  and Japan joined in the Battle Cruiser race before and during the war. Unlike Britain the United States had concentrated on building battleships but following the war began to design and build its own class of massive battle cruisers.

800px-InvincibleBlowingUpJutland1916

HMS Invincible Blowing Up at Jutland 

During the war the weaknesses of the type were exposed during the Battle of Jutland where three British Battle Cruisers, the HMS InvincibleHMS Indefatigable and HMS Queen Mary blew up with the loss of most of their crews; of the 3311 officers and sailors on the ships only 26 survived. The HMS Lion was almost lost in a similar manner but the heroic actions of her crew saved her from her sisters fate. The British ships had glaring deficiencies in armor protection and the arrangement of their ammunition magazines and hoists which certainly contributed to their loss. Their German counterparts on the other hand proved much tougher and though all sustained heavy damage while engaging British Battleships and Battle Cruisers, only one the Lützow was lost. She absorbed over 30 hits from large caliber shells and only lost 128 crew members.

HMS Hood

As the war progressed other Battle Cruisers were built, the British launched the HMS Repulse and HMS Renown and completed the HMS Hood shortly after the war was over. The Japanese built the four ship Kongo class from a British design, the first of which, the Kongo was completed in a British yard. As the powers embarked on the next Naval Race planners and naval architects designed ships of massive firepower, better protection and higher range and speed. All would have been better classed as Fast Battleships.

The British designed and began construction on the G3 class in 1921, while the Japanese began work on the Amagi Class, and the United States the Lexington Class. However the construction and completion of these ships as Battle Cruisers was prevented by the Washington Naval Treaty.

The treaty, which was ratified in 1922 limited the United States and Great Britain to a maximum of 525,000 tons in their battle ship fleets and 125,000 tons in aircraft carriers.  The Japanese agreed to a limit of 315,000 tons and the French and Italians 175,000 tons each. Tonnage for battleships was limited to a maximum of 35,000 tons with a limitation on guns size to 16 inches.  Since the bulk of the ships planned or being built by the US and Japan exceeded those limits they would be effected more than the British whose post war shipbuilding program had not begun in earnest, in fact the G3 Class had just been approved for construction.

The G3 class would have comprised four ships and been similar to the N3 Class Battleships. They were very well balanced ships and would have mounted nine 16” guns in three turrets on a displacement of 49,200 tons and deep load of 54,774 tons. They had an all or nothing protection plan meaning that the armored belt was concentrated in vital areas around the armored citadel, conning tower, turrets and magazines and engineering spaces. Their armor belt would have ranged from 12-14 inches, deck armor from 3-8 inches, conning tower 8 inches, barbettes 11-14 inches, turrets 13-17 inches and bulkheads 10-12 inches. Their propulsion system of 20 small tube boilers powering 4 geared steam turbines connected to 4 propeller shafts would have produced 160,000 shp with a designed speed of 32 knots.

The four ships, none of which were named were ordered between October and November of 1921. Their construction was suspended on November 18th 1921 and they and the N3 Battleships were cancelled in February 1922 due to the limitations of the Washington Naval Treaty. Many concepts of their design were incorporated in the Nelson Class battleships which were a compromise design built to stay within the limits of the treaty.

The four planned Japanese Amagi Class ships would have mounted ten 16” guns on a displacement of 47,000 tons at full load. Their propulsion system 19 Kampon boilers powering four Gihon turbines would have given them a maximum speed of 30 knots, They would have had less protection than the G3 ships being more of a traditional Battle Cruiser design. As a result of the Washington Naval Treaty the Japanese elected to convert two of the ships, the Amagi and Akagi to aircraft carriers. Amagi was destroyed on the ways during the great Tokyo earthquake and Akagi was completed as a carrier. The other two vessels were scrapped on the ways.

The United States Navy planned the six ship Lexington Class. These ships would have mounted eight 16” guns on a ship measuring 874 feet long and 105 feet in beam, displacing 43,254 tons at full load, or nearly the size of the Iowa Class battleships. They would have had a maximum speed of 33 knots being powered by 16 boilers which drove 4 GE electric turbines producing 180,000 shaft horse power. Theirs was a massive engineering plant and while the class did not have as heavy armor protection as either the G3 or Amagi classes, they were superior to them in speed as well as endurance. Upon ratification of the Washington Naval Treaty four of the six ships were cancelled and the remaining two, the Lexington and Saratoga competed as aircraft carriers.  Had any of the ships been completed as Battle Cruisers it is likely due to their speed that they would have operated primarily with the the carriers that the US Navy built during the 1930s.

One can only speculate what the navies of World War II would have looked like had the Washington and the subsequent London Naval Treaties not been ratified. One can also only imagine how the war at sea would have been different had the ships completed as carriers been completed as Battle Cruisers.

However that was not to be, of the planned 14 ships of these three classes only three were completed, all as aircraft carriers, ships that helped to forge the future of naval operations and warfare for nearly a century. Thus the uncompleted ships are an interesting footnote in naval history yet have their own mystique. and one might wonder if the new aircraft carriers currently being built by the United States, Britain, China, India and other nations will also be displaced by advancing technology as were these ships.

Until tomorrow,

Stringbags vs. the Bismarck

A couple of days ago I reposted an article about the sinking of the HMS Hood by the German Battleship Bismarck. The story of the Bismarck is an epic saga of naval warfare and history. It is tragedy played out as if scripted by a playwright in three parts. The first was the sinking of the illustrious “Mighty” Hood by the Bismarck on May 24th 1941. 

The second, which I deal with today, was the pursuit and search for Bismarck by the British Home Fleet and the desperate attempt of the British to find a way, any way, to slow Bismarck down and bring her to battle, before she could return to the safety of Nazi occupied France.  The final chance to stop the mighty German Leviathan came as night fell on May 26th. 

I hope you appreciate the heroism of the men who flew the hopelessly obsolete aircraft who dealt the blow which crippled Bismarck. This is a re-wright of past articles and I will post the final article about the sinking of the Bismarck tomorrow.

On May 24th 1941 the German Battleship Bismarck had sunk the celebrated Battlecruiser HMS Hood in the Denmark Strait and had seriously damaged the new Battleship HMS Prince of Wales. The news of the disaster stunned the Royal Navy. Fighting a war on multiple fronts and now standing alone against Hitler’s Germany the British deployed every warship available to find and sink Bismarck.

On the evening of the 24th of May Bismarck was being shadowed by the heavy cruisers HMS Norfolk and HMS Suffolk. To the east the ships of the Home Fleet, Britain’s last line of defense under the command Admiral John Tovey was making the fastest speed to intercept the Bismarck.  Far to the southeast, Vice Admiral James Sommerville’s  “Force H” comprised of the carrier HMS Ark Royal, the fast but elderly battlecruiser HMS Renown, and the light cruiser HMS Sheffield were ordered to leave the vital convoy which there were escorting and proceed to the northwest to join the hunt for the German battleship.

With Bismarck loose the North Atlantic Convoys on which Britain depended for her survival were vulnerable. The previous year the commander of the Bismarck task force Admiral Günther Lütjens with the Battlecruisers Scharnhorst and Gneisenau had wreaked havoc on the convoys. Now of Britain was on edge with the news of Bismarck’s break out into the Atlantic. Churchill was furious with the Navy when the Mighty Hood, the largest and most powerful ship in the Royal Navy destroyed with the loss of all but three crew members. Now every effort was directed to find and sink the Bismarck.

Accompanying the Home Fleet was the brand new Aircraft Carrier HMS Victorious with 825 Naval Air Squadron embarked under the command of LCDR Eugene Esmond. The squadron, like many in the Fleet Air Arm was equipped with Fairy Swordfish Torpedo Bombers. The squadron had seen action aboard other carriers in the North Atlantic, the Norway Campaign and in the Mediterranean before being assigned to the Victorious. On the night of 24 May 1941, in foul North Atlantic weather the Victorious launched nine Swordfish from a range of 120 miles in a desperate attempt to slow the Bismarck down. Esmond’s squadron scored one hit amidships on the Bismarck which did no serious damage.

825 Squadron Swordfish on HMS Victorious

About 6 hours after the attack by Victorious’s Swordfish, Bismarck shook her pursuers and disappeared into the mists of the North Atlantic, while her consort, the Heavy Cruiser Prinz Eugen escaped to the northwest in order to conduct independent raiding operations. Not knowing the location or course of the Bismarck the Royal Navy frantically searched for the German Leviathan. Most of the ships nearest to Bismarck’s last reported position were low on fuel and others seemed too far away to be of any importance in the search.

However the British were able to intercept and decode some German communications which indicated that Lütjens had orders to steam to Brest, in German occupied France for repairs.

Though the British believed that the Bismarck could be headed toward Brest they could not be sure, as each hour passed the chances of finding and bringing Bismarck to battle diminished. For nearly 36 hours the British searched in vain for the Bismarck, and for much of the 25th Tovey’s squadron was searching in the wrong direction. Then at 1030 on the 26th of May their luck changed.

Likewise the crew of the Bismarck believed with every hour that they would soon be under the protection of Herman Goering’s Luftwaffe and safely in France, but the good fortune of the British was the worst thing that could happen to the 2200 men aboard Bismarck.

On that morning a Royal Air Force Coastal Command PBY Catalina co-piloted by US Navy Ensign Leonard Smith found the Bismarck. Once Smith transmitted Bismarck’s location every available ship converged on her location but unless something could be done to slow the German down the chances bringing her to battle diminished by the hour.

The only heavy forces close enough to successfully engage Bismarck, Tovey’s battleships HMS King George V and HMS Rodney were over 100 miles behind Bismarck, too far away unless Bismarck changed course or could be slowed down. Somerville’s Force H to the south did not have the combat power to survive a surface engagement with the Bismarck should they encounter the Bismarck without the support of other heavy fleet units. Even so Sommerville was willing to risk the Renown in a suicidal action to bring Bismarck to battle if it would allow Tovey to catch her before she could escape. Desperation was the order of the day for both sides.

The situation was desperate, if Bismarck could not be slowed down she would be in range of heavy Luftwaffe Air support as well as support from U-Boats and destroyers based in France. Unless something akin to a miracle occurred Bismarck would join the Scharnhorst and Gneisenau in Brest and with the addition of Bismarck’s sister-ship Tirpitz form a surface squadron strong enough to devastate British shipping in the Atlantic.

Ark Royal’s aircraft were the last hope of slowing down Bismarck before she could effect her escape and emerge from the Atlantic after having dealt the Royal Navy a devastating blow.

The strike aircraft available on Ark Royal were the most unlikely aircraft imaginable to successfully carry out such a mission. Ark Royal’s 820 Squadron, like Victorious’ 824 Squadron was equipped with Fairy Swordfish Mk 1 Torpedo Bombers. These were biplanes with their crew compartment exposed to the weather.

Introduced to the Navy in 1936 the aircraft was an antique compared with most aircraft of its day. Likewise the Mark XII 18” torpedo carried by the aircraft was smaller or slower and equipped with a less powerful warhead than comparable torpedoes used by other navies. Despite their limitations the venerable Swordfish had performed admirably during the early part of the war sinking or damaging three Italian battleships at Taranto in November 1940. Their success against the Italians at Taranto gave inspiration to the Japanese for their attack against the U.S. Pacific Fleet at Pearl Harbor the following year. But now, in the face of foul weather and a powerful opponent the Swordfish were all the Royal Navy had left to stop Bismarck before she could make her escape.

Bismarck steering erratically after the torpedo hit to her stern

With that in mind  Sommerville in sent his light cruiser, the  HMS Sheffield ahead to shadow Bismarck while Ark Royal closed in to launch her Swordfish against Bismarck. The first wave of aircraft strike, unaware Sheffield was near Bismarck mistakenly attacked the British cruiser. Thankfully, the new design magnetic detonators failed to detonate the torpedoes saving Sheffield from destruction. With little daylight left the aircraft returned to Ark Royal where they rearmed with torpedoes equipped with contact fuzes and refueled by flight deck crew laboring in rain and 50 knot winds blowing across the carrier’s flight deck. Just before 8 p.m. 15 Swordfish of 820 Squadron took off for what they knew was the very last chance to attack Bismarck before night fell. If they failed Bismarck would most certainly escape.

As darkness began to fall the 15 Swordfish from 820 Squadron descended through the clouds to attack the German ship. Just fifteen obsolete aircraft and thirty men attacking the most powerful warship afloat. They dispersed and attacked from all points of the compass. Bismarck twisted and turned and fired all of her guns at the attacking aircraft. The Germans fired with every weapon available, even the 15″ guns of her main battery, which she fired her into the ocean ahead of the Swordfish. It appeared for a moment that the Bismarck had successfully avoided serious damage. All but two torpedoes missed.  One torpedo struck the German midships and barely dented her massive armor. However a second torpedo, launched by a Swordfish piloted by Lieutenant John Moffat hit Bismarck in her weakly armored stern. The hit jammed Bismarck’s port rudder at a 12 degree angle, and destroyed her steering gear. The weather was such that German damage control teams could not repair the damage. Bismarck now steamed in circles, unable to maneuver. This enabling Tovey with King George V, Rodney, the heavy cruisers Norfolk and Dorchester, as well as a number of destroyers to catch up with the elusive German.

The attacks of the antiquated Swordfish on the Bismarck achieved results that no one in the Royal Navy expected. When reports indicated that Bismarck had reversed course following the torpedo attack Tovey could not believe them. It was only when lookouts aboard Sheffield confirmed the reports from the Swordfish that Tovey realized that Bismarck must have been damaged and was unable to maneuver.

It was a dramatic and unexpected turn of events. The German crew sank into gloom as the night went on and they dealt with torpedo attacks from the British Destroyers as Tovey’s battleships moved in for the kill.
