British Bulwarks: The King George V Class Battleships

HMS King George V

This is the third in a series of five 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. This article covers the British Royal Navy King George V Class battleships. Part one covered the Italian Vittorio Veneto class entitled The Pride of the Regina Marina: The Vittorio Veneto Class Battleships. Part two French Firepower Forward: The unrealized potential of the Dunkerque and Richelieu Class Battleships covered the French Dunkerque class and Richelieu class Battleships. Part Four the American North Carolina and South Dakota Classes. 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.

HMS King George V in 1941

In the wake of the First World War the major naval powers entered into an agreement restricting the construction of capital ships and limiting the numbers that treaty signatories were allowed to keep. As a result numerous ships were scrapped or disposed of and the majority of planned ships were either cancelled while building or never laid down. In some cases to comply with treaty restrictions ships such as the Royal Navy’s Nelson Class which was a compromise design which sacrificed speed for protection and firepower.  By the late 1920s the Royal Navy’s battle force was comprised of the Nelson’s, the fast Battlecruisers Hood, Renown and Repulse and 10 ships of the Queen Elizabeth and Revenge classes all designed before the First World War.

King George V Class Quad Turret being built

The Royal Navy began planning for a new class of battleships in 1928 but the plans were shelved with the signing of the London Naval Treaty which continued the “building holiday” on capital ship construction as well as size and armaments until 1937.  With the realization that its battle force was becoming dated as other nations laid down new classes of battleships the Royal Navy recommenced planning in 1935.  The Navy planned to build to the maximum of the 35,000 displacement limitation and placed a great measure of emphasis on armor and protection. The ships were designed to achieve a 28 knot speed which made them faster than all British battleships although slower than the Battlecruisers. The planners had alternative designs to use 14”, 15” or 16” guns with the Navy favoring the 15” models which had equipped all of their other ships with the exception of the Nelson’s. However the Admiralty to use 14” as the government was endeavoring to negotiate with other powers to impose a 14” limitation on armament for new battleships.  While the Americans and French agreed to the limit neither the Japanese nor Italians followed suit and as a result all new battleships of other powers had larger guns than the King George V Class ships with the French and Italians opting for 15”on the Vittorio Veneto Class, the Americans 16” on the North Carolina, South Dakota and Iowa Classes and the Japanese 18” guns for their Yamato Class. The Germans who were not a signatory built their Scharnhorst Class with 11” although they were planned as 15” ships and would equip the Bismarck Class with 15” guns.  The Royal Navy attempted to rectify this by placing more guns on the ships than those of other navies but the planned armament of twelve 14” guns mounted in quadruple turrets but this was impossible on the 35,000 platform without compromising protection or speed.  Thus the Admiralty compromised on 10 guns mounted in 2 quadruple and 1 twin turret.

ONI Drawing of King George Class

The ships displaced a full load displacement of 42,237 tons in 1942 which had increased to 44,460 tons in  1944. The were 745 feet long had a beam of 103 feet, a top speed of 28 knots with a cruising range of 5,400 nautical miles at 18 knots. Their relatively poor endurance limited their operations in the Pacific and even nearly caused King George V to have to abandon the chase of the Bismarck in May 1941.

The main batteries of the ships proved problematic in combat with the quadruple turret design causing all the ships problems. This was demonstrated in the engagement of the Prince of Wales against the Bismarck as well as the King George V in its duel with the German behemoth when A turret became disabled and completely out of action for 30 minutes and half of the main battery being out of action for most of the engagement for mechanical reasons.  The Duke of York achieved excellent results against the Scharnhorst but even in that engagement the main battery was only able to be in action 70% of the time.  One of the other drawbacks of the design was that in order to replace a gun due to wear that the turret itself had to be dismantled in order to remove and replace the guns.

The main secondary armament of 5.25” dual purpose guns in twin mounts suffered from poor rate of fire and slow traverse well below their designed standards.

The mounting of the armament was designed to provide protection against turret explosions which could potentially detonate the ship’s magazines.  The main side and underwater protection scheme was sound and protected the ships well in combat.  The vertical protection was also sound as was the protection afforded to the turret barbets and placement of the magazines to shield them from plunging fire.  Only the Prince of Wales was lost due to enemy action had later examination of her wreck revealed that the culprit was a torpedo which detonated in a propeller shaft outside of the armored belt which caused uncontrolled flooding when she was attacked by Japanese aircraft on 8 December 1941.

The propulsion systems developed problems after 1942 when fuel oil quality was decreased because of the need for aviation gas.  The new mixtures which were higher viscosity and contained more water than the boilers could effectively burn increased maintenance costs and decreased efficiency. To compensate the Admiralty designed new higher pressure fuel sprayers and burners which returned the boilers to full efficiency.

The lead ship of the class the King George V was laid down on 1 January 1937, launched on 21 February 1939 and commissioned on 11 December 1940.  As the flagship of the Home Fleet she took part in the unsuccessful search for the Scharnhorst and Gneisenau and in the hunt for the Bismarck in which she earned lasting fame in helping to sink that ship.  She took part in the Murmansk convoy protection as well as Operation Husky, the invasion of Sicily before sailing to the Far East for operations against the Japanese. She finished the war with the British Pacific Fleet and was present at the Japanese surrender in Tokyo Bay.  She returned as flagship of Home Fleet until she was decommissioned in 1949. She was subsequently sold for scrap in 1957.

Prince of Wales pulling into Singapore

The second ship the Prince of Wales laid down on 1 January 1937, launched on 3 May 1939 and commissioned 19 January 1941 although she was not officially completed until March 1941. Her initial operation came in May 1941 when she sailed with the HMS Hood to intercept the Bismarck. When she sailed she still had shipyard technicians aboard.  Damaged in the action she did score an important hit on Bismarck which cut a fuel line making her forward tanks inaccessible and causing her to make her run for Brest which she did not complete. Another hit damaged her aircraft catapult and a third an electric dynamo.

Church Service on Prince of Wales at Argentia Bay with Churchill and Roosevelt in attendance

Following repairs she carried Winston Churchill to the Argentia Bay Newfoundland where he met with Franklin D. Roosevelt and together drafted the Atlantic Charter. She accompanied the HMS Repulse to Singapore to bolster the British presence in the Far East but without air cover was sunk by Japanese aircraft which struck her with 4 torpedoes and a bomb, the key hit being a lucky hit on her propeller shaft which caused flooding that caused a loss of power to pumps and anti-aircraft defenses.

Prince of Wales sinking and being abandoned

The third ship the Duke of York was laid down 5 May 1937, launched on 28 February 1940 and commissioned 4 November 1941. She provided convoy escort for the Lend Lease convoys to the Soviet Union as well the sinking of the Scharnhorst on 26 December 1943 during the Battle of North Cape. She was transferred to the Pacific in 1944 and served at Okinawa.  She was decommissioned in 1949 and scrapped in 1957.

Duke of York

The fourth ship of the class the Howe was laid down on 1 June 1937, launched 9 April 1940 and commissioned on 29 August 1942.  She served with the Home Fleet and in the Mediterranean until she was transferred to the Pacific in August 1944. She was stuck by a Kamikaze in May 1945 and Howe was sent for refit at Durban South Africa. She was still in refit when the war ended. She returned home and was placed in reserve in 1950 and scrapped in 1958.

HMS Howe

The last of the class the Anson was laid down 20 July 1937, launched 24 February 1940 and commissioned on 22 June 1942. She operated in the Mediterranean and the North Atlantic and was sent to the Pacific in 1945 where she accepted the surrender of the Japanese Forces at Hong Kong. She returned to Britain and was decommissioned in 1941 and scrapped in 1957.

HMS Anson

The ships had rather unremarkable careers for the most part with the exception of the Prince of Wales and King George V in the hunt for the Bismarck and the Duke of York sinking the Scharnhorst. They had a number of technical problems which limited their operations in the war. However they and their brave crews deserve to be remembered as helping to hold the line against the Axis in the early years of the war and sank two of the four German Battleships lost during the war.  This alone was as remarkable achievement as of their contemporaries only the USS Washington sank an enemy battleship in combat.

The Pride of the Regina Marina: The Vittorio Veneto Class Battleships

Vittorio Veneto and Littorio

This is the first in a series of five 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. 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.

Technically many 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 them most were officially listed as complying with the treaty restrictions.

The Washington Treaty placed a limit on the displacement and armament of battleships. The London Treaty continued them 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 had been bound by the much more stringent Treaty of Versailles restrictions 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 Royal Italian Navy had not completed a battleship design since the Andria Doria Class which were constructed between 1912 and 1915 and modernized given an extensive modernization between 1937 and 1940.  A subsequent class the Francesco Caracciolo class was started during the First World War but no ships of the class were completed.

In the 1930s a new naval arms race was underway in the Mediterranean as 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. Mussolini saw the new French ships as a threat to the control of the Mediterranean 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, large, fast and heavily armed 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. Armed with a main battery of 9 15” guns in triple turrets and a secondary armament of 12 6” and 12 3.5” guns along with 20 37mm and 30 20mm anti-aircraft guns and capable of 29 knots in service and with a relatively short range of 3900 miles at 20 knots they were formidable ships for operations in the Mediterranean. They were well protected although their Pugliese torpedo defense system proved inferior to traditional designs.

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. The high muzzle velocity led to a barrel life of only about half that of their counterparts and inconsistent shell fall patterns.  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

Vittorio Veneto: The Vittorio Veneto was laid down 1934 along with her sister the Littorio and was launched on 25 July 1937 and commissioned on 28 April 1940. 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 Vittorio Veneto she was interred in the Great Bitter Lake and was returned to Italy where she was decommissioned and scrapped beginning in 1948.

Roma

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 discovering the ruse launched air attacks by 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 soon after by a second Fritz-X which hit in the forward engine room causing catastrophic damage and igniting the number two turret magazine blowing the turret off the ship and causing the ship to capsize and break in two as 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.

The Fritz-X Radio Guided Bomb

Impero: Impero was laid down but never completed and scrapped after the war.

The Vittorio Veneto class was a sound design and operationally successful against the Royal Navy and the brave sailors of the Regina Marina who manned these fine ships should not be forgotten.

Four of a Kind: The Illustrious Class Aircraft Carriers

HMS Illustrious in 1944

In the mid-1930s the Royal Navy recognized the need to develop and built new Fleet Carriers. The Illustrious Class of four ships was ordered as part of the 1936 Naval Program.  The four ships of the class HMS Illustrious, HMS Formidable, HMS Victorious and HMS Indomitable were some of the most important ships to see service in the Royal Navy in the Second World War and would see action in the Atlantic, Arctic, Mediterranean, Indian Ocean and Pacific.  They were tough ships and all sustained serious damage at least once in their careers that might have sunk other ships.  Different in concept than the Royal Navy’s only modern carrier the Ark Royal they displaced more than the U.S. Navy Yorktown Class and just somewhat less than the following Essex Class ships although they were over 100 feet shorter in length as compared to the American ships.

The class was built with an armored flight deck which covered the hangar deck with both as an integral part of the ship’s structure and defense.  The American ships hanger and flight deck were part of the superstructure with the armored deck being that of the hangar deck itself.  This provided advantages in protection against bombs and later Kamikazes but there was a trade off in both aircraft capacity and the ability for the ships to handle the larger aircraft that came into service following the Second World War.  As designed the ships carried just 36 aircraft as compared with the 80-100 aircraft of the American ships and the 72 that the Ark Royal was rated at.  Later in the war the Royal Navy adopted the American practice of an air park on the flight deck which increased their capacity to up to 70 aircraft. The last ship of the class, the Indomitable was built to a modified deign with an expanded two deck hangar with increased aircraft capacity similar to that of the Ark Royal.  An additional drawback to the design was that any bomb which penetrated the armored flight deck exploded inside the hangar causing deformation to the actual ship’s structure.

British defensive doctrine for these carriers was focused on the passive protection provided by the armored flight deck and by a far heavier anti-aircraft battery than the Yorktown Class and comparable to the Essex Class. This was a different doctrine than that of the Americans and the Imperial Japanese Navy which embarked large air groups believing that the aircraft were integral to the defense of the ship.

The ships displaced 28,919 tons full load and were capable of steaming at 30.5 knots with an operational range of 11,000 nautical miles at 14 knots, far more than any previous Royal Navy carrier but far less than the Essex class which could steam 20,000 nautical miles at 15 knots. The Essex Class ships were had a greater displacement as well as a higher top speed of 33 knots.  The Illustrious class was best suited for operations in the Atlantic and Mediterranean and less suited to the vast expanse of the Pacific where they would spend the last year of the war.

Illustrious under attack by German Bombers

HMS Illustrious: Illustrious was laid down in April 1937, launched in April 1939 and commissioned in May 1940. Upon commissioning she and her air group deployed to the Mediterranean where in the dark days following the fall of France they escorted vital convoys, supported the Royal Army in the war in North Africa and conducted strikes against Italian shore installations and fleet units.  Illustrious launched the first major raid against an enemy shore base by carrier aircraft on 11 November 1940. Her aircraft from number 813, 815, 819 and 823 Squadrons made a night attack on the Naval Base at Taranto sinking the battleship Conte di Cavour and heavily damaging the battleships Andrea Doria and the new battleship Littorio and moderate damage to the Caio Dulio This strike helped cripple Italian naval power and helped give the Japanese inspiration for the Pearl Harbor attack.    On 10 January she suffered severe damage from 6 bomb hits while escorting a convoy near Malta. She was attacked again at Malta causing more damage and she was withdrawn from action and sent to Norfolk Naval Shipyard for repairs. The damage was severe enough to keep her out of the war until May of 1942.  One of her shafts was so badly damaged that it had to be cut away and could not be replaced which reduced her speed to 23 knots. On her return to action she covered the landings against the Vichy French island of Madagascar and the Sicily landings. In 1944 she was in action with the Far East Fleet conducting raids against Japanese held islands in Indonesia and in 1945 was in action as part of the British Pacific Fleet where she saw action at Okinawa where she was hit by two Kamikazes and Formosa where a near miss close aboard by a Kamikaze caused severe damage below her waterline.  She sailed home where she underwent repair until 1946 when she was returned to duty as a training carrier in which capacity she served until she was decommissioned and scrapped in 1954.

Grumman Marlett (F4F Wildcat) on flight deck of HMS Formidable

HMS Formidable: Formidable was laid down in June 1937, launched in August 1939 and commissioned in November 1940.  She actually “launched herself” a half hour before her Christening ceremony which gave her the nickname “The ship that launched herself.”  Formidable saw action in the Mediterranean in 1941 and was heavily damaged by two 1000 kg bombs while escorting a Malta Convoy. This put her out of action for 6 months as she was repaired at Norfolk Naval Shipyard.  On her return she saw service first in the Indian Ocean and then in the invasions of North Africa, Sicily and the Italian Campaign. She also saw service in the Arctic sinking U-331 and in raids against the German Battleship Tirpitz.  She was in action in 1945 against the Japanese with the British Pacific Fleet where she relieved Illustrious after that ship was withdrawn from action. On 4 May 1945 while supporting operations off Okinawa she suffered massive damage from a Kamikaze, temporary repairs kept her in action until hit by another Kamikaze on 9 May. She was withdrawn from action and a fleet review determined that she was not economically repairable in the austere post war years. She was placed in reserve in 1947 and sold for scrap in 1953 with the scrapping taking place in 1956.

HMS Indomitable

HMS Indomitable: Indomitable was built to a modified design which allowed her to operate far more aircraft than her sisters. She was laid down in November 1937, launched in March 1940 and commissioned in October 1941. She was slated to accompany the HMS Prince of Wales and HMS Repulse to the Far East and the defense of Singapore but ran aground on a coral reef during her shakedown cruise in the Jamaica which prevented that deployment.  After repairs she operated with the Far East Fleet in the Indian Ocean and took part in the invasion of Madagascar in November 1942.  In July of 1942 she took part in the Malta resupply mission Operation Pedestal where she was heavily damaged by two 500 kg bombs which penetrated her flight deck. She was withdrawn to the United States for repairs which lasted until February 1943 when she returned to the Mediterranean.  She took a torpedo hit from a German Ju-88 bomber on 15 June 1943 during the build up to the invasion of Sicily and again returned to the United States for repairs which were completed in February 1944. She then took part in operations with the Far East Fleet in the Indian Ocean before joining the British Pacific Fleet in 1945. She received minor damage from a Kamikaze hit on 4 May 1945 while operating near Okinawa. She finished the war in good shape compared to Illustrious and Formidable but was damaged by an internal fire and explosion in 1947 the damage from which was never repaired. She remained in service until she was placed in unmaintained reserve in 1953 and scrapped in 1955.

HMS Victorious

HMS Victorious: The Victorious was probably the most celebrated aircraft carrier in the history of the Royal Navy. Her World War Two service was remarkable by any standard and she was the only ship of her class to be modernized to carry jet aircraft following the war being refitted in much the same way as the American Essex Class ships were in the 1950s with an angled flight deck.  She was laid down in May 1937, launched in September 1939 and commissioned on 14 May 1941. Within 10 days of her commissioning she was taking part in the Hunt for the Bismarck and her Swordfish torpedo bombers scored one torpedo hit on that ship.  She saw much action in the North Atlantic and Arctic escorting convoys and deterring forays of German raiders into the Atlantic. She served in the Mediterranean during some Malta operations including Operation Pedestal and the Operation Torch landings in North Africa.  Due to the shortage of U.S. Carriers from heavy combat in the South Pacific in 1942 Victorious was “loaned” to the U.S. Navy deployed to operate with the U.S. Pacific Fleet following refits to operate U.S. built aircraft. She operated in the South Pacific from March to September of 1943 with the USS Saratoga in operations against the Japanese to include the New Georgia landings. She returned home and took part in raids against the Tirpitz which put that ship out of action for several months. She deployed to the Far East in 1944 and support operations in the Indian Ocean before being transferred to the British Pacific Fleet.

Victorious on Fire off Okinawa

She was involved in extensive Pacific operations including Okinawa and the raids on mainland Japan. She was stuck on a number of occasions by Kamikazes but remained in action.  After the war she was modernized and remained in service until 1969 when the Royal Navy decided that it was going to end its fixed wing operations and decommission its remaining attack aircraft carriers. She was broken up at Faslane beginning in 1969.

The modernized HMS Victorious

The Illustrious Class ships were great ships which performed admirable work in the Second World War. They and their brave crews continued the proud tradition of the Royal Navy. It is my hope that at least the new Queen Elizabeth Class carriers will be renamed for a ship of this class, preferably Victorious.

Peace

Early British Aircraft Carriers: HMS Argus, Furious, Eagle, Courageous, Glorious, Hermes and Ark Royal

The British Royal Navy was the first to grasp the importance of the aircraft carrier and the first to embark on a carrier construction program and establish a Fleet Air Arm. Between the end of the First World War and the beginning of the Second the Royal Navy would build 7 carriers.  These ships in almost all cases were somewhat experimental as the Royal Navy experimented with flight deck and island designs, arresting systems, catapults and designs. The initial ships were all converted from other types with only two the Hermes and Ark Royal being built from the keel up as carriers.

HMS Furious

HMS Furious: Furious was built as a Courageous class large light cruiser and mounted two 18” guns in single turrets. A flying off platform was added as was a second flight deck aft following the removal of those guns. She operated Fleet Air Arm Sopwith Pups but aircraft that attempted to land on her aft deck encountered severe turbulence caused by the air currents coming around the superstructure and funnel gasses. She was the first ship to land an aircraft underway on August 2nd 1917 during her trials however the pilot Squadron Commander Edwin Dunning was killed when his Pup’s engine choked on a later attempt. After the war Furious was laid up until she was taken in hand for conversion to an Aircraft Carrier between 1921 and 1925.  When she was completed she could operate a 36 aircraft air group. Between the wars she supported Fleet operations and was used in the testing and evaluation of aircraft. She conducted the first night landing on a carrier when she landed a Blackburn Dart on 6 May 1926. She received a number of overhauls and modernizations. During the war she supported numerous fleet operations including the North Africa landings, operations in the Mediterranean and operations against German fleet units in Norway including the Battleship Tirpitz. Her limitations began to show and she was placed in reserve in September 1944 and paid off in April 1945. She was subsequently used to evaluate the effects of explosives on her structure. She was sold for scrap in 1948.

HMS Argus 1918

HMS Argus: The Argus was converted from the Italian Ocean Liner Conte Rosso which was purchases by the Royal Navy with the intent of converting her into an Aircraft Carrier.  She was built with a flush unobstructed flight deck after the Royal Navy’s unsuccessful divided flight deck experiment used on the HMS Furious following her conversion from a Light Battle Cruiser to a carrier. Argus was launched in 1917 and commissioned just prior to the end of the war on September 19th 1918.  Argus was small (15,775 tons) She was only capable of 20 knots and carried 18 aircraft. Like the USS Langley she was not a true frontline though she was used in that role as well as a training ship until the end of the 1920s when she was withdrawn from frontline service. Since she was built before the Washington Naval Treaty she was considered an experimental ship and not counted against Britain.  By the 1930s she was regulated to serving as a tender for remote controlled DH.82B Queen Bees.  During the early part of World War II the Royal Navy suffered heavy losses and the Argus assumed front line duties escorting convoys in the Atlantic and Mediterranean and ferrying badly needed aircraft to Malta for the Royal Air Force. She finally was withdrawn from service in 1944 and used as an accommodation ship until scrapped in 1946.

HMS Eagle 1942

HMS Eagle: Eagle was laid down as the Chilean Battleship Admirante Cochrane prior to World War I and her construction was suspended until the Royal Navy purchased her for completion as a through deck Aircraft Carrier. She was 667.5 feet long and displaced 26,000 tons full load and carried up to 21 aircraft.  She conducted sea trials but was taken back to the shipyard for improvements including an all oil-fired plant, anti-torpedo bulges and a longer island structure. She was commissioned in 1924 an saw much service through the 1920s and 1930s serving in the Mediterranean and the Far East until the outbreak of the Second World War.  With the outbreak of hostilities she was recalled from the Far East where she spent most of her time in the Mediterranean escorting convoys, launching airstrikes against Italian bases and fleet units sinking the submarine Iride and the depot ship Monte Gargano in the Gulf of Bomba on 22 August 1941.

HMS Eagle burning and sinking

She was damaged by near misses by Luftwaffe bombers in October returned to England for repairs before returning to the Mediterranean in February 1942. She and her aircraft were very important in the defense of Malta until she was sunk during another Malta relief mission Operation Pedestal by the German U-Boat U-73 on 11 August 1942.  Hit by 4 torpedoes she sank in 4 minutes with the loss of 160 officers and crew.

HMS Hermes

HMS Hermes: The Hermes was the first carrier built as such from the keel up using a cruiser type hull.  The design of the Japanese carrier Hosho was influenced by Hermes which was launched before Hosho was laid down although Hosho commissioned earlier. Hermes was a pioneer design with a full length flush flight deck and starboard side island structure. She was limited by her small size and slow speed although she could embark almost as many aircraft than could the much larger Eagle. She did have significant limitations including protection, endurance, only 6,000 miles at 18 knots and small air group size which varied from 15-20 aircraft. She primarily served on the China Station until placed in reserve in 1937. In 1939 she was reactivated briefly serving with the Home Fleet before being assigned to the South Atlantic Station. She sailed with HMS Prince of Wales for the Far East in late 1941 but did not accompany the Prince of Wales and Repulse to Singapore where they would be sunk when trying to intercept a Japanese convoy on December 8th 1941.

HMS Hermes sinking after Japanese air attack new Ceylon

She remained at Ceylon and escaped from the harbor before the Japanese carrier’s arrived, however returning to port she was spotted by a Japanese reconnaissance aircraft and attacked by 70 Japanese attack planes which hit her 40 times sinking her with the loss of 307 of her 664 man crew on 9 April 1942.

HMS Glorious: The Glorious was one of the three Courageous class Battlecruisers designed and built in World War One. Her sister ship HMS Furious had already been taken in hand for complete conversion to an aircraft when the Washington Naval Treaty was ratified. Under the terms of the treaty the Royal Navy had to significantly reduce its number of capital ships.  With their large size and high speed the Courageous class ships, like the American Lexington class were ideal candidates for conversion to aircraft carriers.  Glorious underwent conversion from 1924 until 1930 when she was recommissioned.  With an overall length of 786 feet and full load displacement of 27,859 tons she could carry 48 aircraft and steam at 30 knots. She would spend much of her career in the Mediterranean and undergo modernization from 1934-1935.  At the outbreak of the war she was in the Mediterranean and would take part in the hunt for the German Pocket-Battleship Admiral Scheer in the Indian Ocean until being brought back to the Home Fleet for operations in the Norwegian Campaign.

As the British withdraw was completed her Commander requested to steam independently to Scapa Flow to hold a courts martial proceeding against his former Air Group Commander. Sailing with two escorting destroyers Glorious was sighted by the German Battlecruisers Scharnhorst and Gneisenau on June 8th 1941.  Unprepared with no Combat Air Patrol up or aircraft at the ready Glorious and her two escorting destroyers were sunk by the German warships. Only 43 of her complement and air group of nearly 1400 men survived.

HMS Courageous: Courageous like her sister HMS Glorious was taken in hand for conversion to an aircraft carrier in 1924 was recommissioned as such in 1928.  She would serve primarily with the Atlantic and Home Fleets between the wars and upon commencement of hostilities.

He became part of a U-Boat Hunter Killer Group and on the 17th of September 1939 barely 2 weeks after the start of the war she was sunk by two torpedoes fired by the U-29 taking with her 518 of her crew including her Captain.  Her loss sent a shudder through the Admiralty and resulted in Fleet Carriers being pulled from this type of duty.

HMS Ark Royal

HMS Ark Royal: Ark Royal was the first truly modern Royal Navy carrier. Designed from the keel up as such she incorporated arresting gear and steam catapults. She also was built with two hangar decks as well as elevators that were integral to the hull and thus protected by the ship’s armor belt. Designed to operate 72 aircraft she normally operated 50-60 as the size and weight of aircraft had increased during the time of her construction and commissioning. Displacing 27,800 tons fully loaded she was 800 feet long and had a top speed of 31 knots and range of 7600 nautical miles (8700 miles) at 20 knots being the only British carrier of the era to compare favorably with her American and Japanese counterparts.  Commissioned in December of 1938 Ark Royal which was intended for service in the Far East was deployed with the Home Fleet and in the Mediterranean until the outbreak of the war. Initially employed on Hunter Killer duty she and her escorting destroyers sank the U-39 on 14 September 1939 followed by the hunt for the Pocket Battleship Graf Spee. She saw action in Norway and was a bulwark of British strength in the Mediterranean where she took part in the attack on the French Fleet at Mes-el-Kébir following the French surrender to Germany and the refusal of the French Commander to either scuttle the fleet or bring to British controlled waters.  She was engaged in numerous engagements and operations including the support of Malta, operations against the Italian Fleet and air strikes on Italian shore installations. She survived frequent air attacks by the Luftwaffe during these operations.  When the Bismarck broke out into the Atlantic Ark Royal was dispatched with Force H to assist in the hunt. Ark Royal’s Fairly Swordfish torpedo bombers found the Bismarck on 26 May 1941 and on their last chance to damage the German behemoth stuck her with a torpedo which jammed the Bismarck’s rudders allowing British Battleships to sink her the following day. She returned to the Mediterranean after this where she was again engaged in protecting convoys bound for Malta. While returning with Force H to Gibraltar following one of these runs on 10 November 1941 she was attacked by U-81 which scored a hit with one torpedo. A combination of poor command response, for which her Captain was found guilty of at court-martial as well as design flaws related to her electric power plant which made damage control nearly impossible once power was lost were responsible for her sinking.

The Royal Navy helped pioneer the development of the aircraft carrier but most of their early ships had significant limitations in design, obsolescent aircraft and poor employment which were responsible for the losses of several of the ships.  However they did contribute to Britain’s ability to survive during the early years of the war.  The ships officers and men of these ships company as well as their air groups helped maintain the sea lanes which kept her in the war and allowed her forces to continue to fight in North Africa during the darkest days of the war.  One can never minimize their service or sacrifice in the especially in the early days of the war.

Today the Royal Navy has no Aircraft Carriers in commission. The last the Ark Royal was paid off this year and it will be nearly a decade before the new Queen Elizabeth class enters service. Until then the Royal Navy will have no capability to project air power in support of any contingency.  Let us hope for Britain that no such contingency arises.

The Treaty Cruisers: A Warship Review

Note: Since childhood I have loved naval history and the study of various types of warship design throughout history. My favorite period is really from the Spanish-American War through the mid 1970’s.  I find the leaps in Naval design and architecture, weapons and fire control systems and the diversity of the types of ships built absolutely fascinating.  Not only initial designs but the various modifications and modernizations of various ships or classes of ships went through during their service careers. The cruisers of the inter-war period were some of the most ascetically pleasing warships to ever grace the high seas. They were well proportioned, and graceful while still looking every part the warship.  This is something that many ships in our modern era lack, despite the fact that their armament despite limited gun power is formidable. With VLS launchers and Harpoon Missile tubes they pack a punch, but unlike the old cruisers, their offensive teeth are hidden. I had the privilege of serving aboard the USS HUE CITY CG-66 which is about the same size and displacement of the Chester Class

I think I actually began reading Naval history back in 2nd or 3rd grade, and it was not uncommon for me to spend hours at the public library going through reference stacks to read old issues of “Jane’s Fighting Ships” and the main collection to check out every book on Naval Warfare and warships that I could find. One of the most interesting types of ship to me was the Heavy Cruisers built under the restrictions of the Washington Naval Treaty. The treaty had several major provisions but today I only deal with the restrictions on Heavy Cruisers, the response of treaty nations to the limitations and the combat summary of each class.  This is all pretty much out of the deep recesses of my sometimes dark mind and tonight I didn’t have to crack a book to write this.  It’s thanks to having one of those phonographic memories that just keeps going around and around. This is another one of the things that I am passionate about.  Anchor’s Away! Peace, Steve+

The Washington Naval Conference of 1921-1922 set a number of limits on warship construction and fleet composition.  One of the ship types limited by the treaties was cruisers, notably heavy cruisers.  These ships, descended from the Armored Cruisers developed by the navies of the great powers prior to the First World War were considered a major part of each of the navies of the signatory nations.  The armored cruisers had 8-10 inch guns and a relatively substantial armored belt.  The type was not particularly successful as with few exceptions they were used in fleet actions where they were under-gunned and under-armored.  They were most successfully used in overseas service against raiders or commerce.  The most famous of the type were the German Scharnhorst and Gneisenau of the German Far East Squadron.  Smaller and faster than a battleship, the type had developed by the 1920s into a ship that could be used for fleet screening and scouting as well as showing the flag in foreign waters where many were found.  The Washington treaty did not limit numbers of these ships as it did Battleships and Aircraft Carriers, but it did place maximums on the gun size and displacement of individual ships.   A heavy cruiser could be armed with 8 inch guns and were limited to 10,000 tons displacement.  Of course this led to compromises in the designs of the ships which frequently gave up protection for speed.

The Americans were the leaders in the development of the treaty cruisers.  The Japanese only built one class of cruiser, the Kako class which complied with the terms of the treaty.  They mounted 6- 8” guns and displaced about 8,600 tons.  They were fast but because of their light displacement were top-heavy.  Subsequent classes, the Nachi and Atago classes violated the tonnage limits by as much as 4,000 tons while the Japanese reported them as 10,000 tons. They were armed with 10-8”guns in five turrets, had good protection and also mounted 12 24” “Long Lance” torpedo tubes.  Two subsequent cruisers of the Kumano and Tone classes were built in the 1930s. The Kumano class of about 13,000 tons were initially classed as “light cruisers” mounting 15- 6” guns prior to being re-armed with 10-8” guns.  The Tone’s mounted 8- 8”guns in 4 turrets all mounted forward leaving the entire aft section for use as a seaplane launching area; the Tone class carried 8 float planes for fleet scouting.

hms exeterHMS Exeter

The British treaty cruisers abided by the limits included the York and Exeter, of the same displacement and armament as the Kako class except they were slower, a common feature of British ships which were generally slower than their American and Japanese counterparts.  The later County class ships were armed with 8- 8” guns and were distinctive looking having three funnels. The County class included such famous ships as the Norfolk, Suffolk and Dorsetshire which played critical roles in the chase and sinking of the German Battleship Bismarck. Australia had two Counties, the Australia and Canberra which did most of their service in the Pacific. The Counties were armed with 8- 8” guns and were distinctive with their three funnels.  They were slower than their Japanese or American counterparts.

uss houstonUSS Houston with President Roosevelt Aboard

The first American treaty cruisers the Pensacola and Salt Lake City of about 9,500 tons with an unusual arrangement of 10- 8” guns mounted in 4 turrets.  However it was the Chester class which was the quintessential U.S. Treaty Cruiser design.  These ships, and the later Astoria class, also displaced 9,500-10,000 tons and mounted 9- 8” guns in three turrets.  A further “treaty” cruiser was Wichita, converted from a St. Louis class light cruiser. All were fast but were lacking in armored protection and none mounted the torpedoes found in Japanese or British ships.  Some of the more notable ships in the U.S. treaty classes included the Houston which served as the Flagship of the Asiatic Fleet which was sunk at the Battle of the Java Sea. The Augusta which took Franklin D Roosevelt to Argentia for the signing of the Atlantic Charter in 1941; The San Francisco which helped stop the Japanese fleet in a point blank encounter in the Naval Battle of Guadalcanal and Indianapolis which with just weeks left in the war having completed the secret mission to deliver the Atomic bomb was sunk by a Japanese submarine.

PrinzEugen-2Prinz Eugen

The Germans did not build true “heavy cruisers” until the late 1930’s and their ships, the Hipper, Blucher and Prinz Eugen mounted 8- 8” guns and displaced about 19,000 tons.  The German “Pocket Battleships” Deutschland, Graf Spee and Admiral Scheer, mounted 6-11” guns on a hull of about 11,000 tons (officially 10,000) in compliance with the Treaty of Versailles restrictions on German battleships.  They were designed to outgun and be more heavily armored than the heavy cruisers and be faster than battleships, much more in the Armored Cruiser tradition.  During the war the German Navy reclassified them as Heavy Cruisers. None of these ships were built under the treaty limits for cruisers.

hms suffolkHMS Suffolk

These ships saw distinguished service throughout the war.  The British ships remained their only heavy cruiser design throughout the war. The ships took part in the sinking of the Graf Spee and Bismarck. They also suffered heavily; York was sunk at Crete and Exeter in the Java Sea. Cumberland and Dorsetshire were sunk by Admiral Nagumo’s carriers which had attacked Pearl Harbor, in the Indian Ocean. Canberra was sunk at the Battle of Savo Island off Guadalcanal.  Some of the British Ships remained in service until the 1950s and all eventually we paid off and sent to the breakers.

The Japanese ships were involved in almost every major action of the Pacific war.  Fast, heavily armed and manned by well trained crews they dominated almost every surface action of the early war in the Pacific.  The were key at the Battle of Java Sea and Savo Island where they annihilated Allied or American cruiser and destroyer squadrons. In action so often they were destroyed leaving only two marginally operational at the end of the war. Three of the four Kako class were lost in the Solomon’s.  They were all involved at Savo Island, and the last survivor, Aoba was lost at in harbor to U.S. air strikes at Yokosuka at the close of the war.  The Nachi class saw considerable service and were the workhorses of the Japanese cruiser force. They were the principle executioners of the ABDA fleet in the Java Sea battles and continued their service until late 1944 and the end of the war. Nachi and Ashigara were sunk in the aftermath of Leyte Gulf while Haguro fought the last surface action of a major Japanese combatant in a surface action of the war against a British force in 1945 and was sunk. and Myoko survived the war in a damaged condition being surrendered in Singapore.  The Chokai class also served throughout the war and three of the four were lost at Leyte Gulf. The Atago and Maya were lost to the U.S. Submarines Darter and Dace, Chokai in the action at Samar to combined U.S. destroyer and air attacks from TAFFY-3. Takao survived the war in a damaged condition having been torpedoed at Leyte Gulf but making port.  Of the later cruisers Mikuma was sunk at Midway and Mogami survived almost unimaginable damage in that battle.  Mogami was sunk by the resurrected Pearl Harbor Battleships at the Battle of Surigo Strait while Kumano and Suzaya were lost off Samar.  Chikuma and Tone also served in many battles, it was Tone’s float plane which was delayed in launching and discovered the U.S. carriers at Midway too late. Chikuma too was lost at Samar; Tone was sunk at anchor at Yokosuka in 1945.  Leyte Gulf in a sense could be described as the “Death Ride” of the Japanese Cruiser force.

The U.S. cruisers fought valiantly in nearly every engagement of the Pacific war and a few in the Atlantic.  Houston was immortalized by her actions with ABDA in the Java Sea against hopeless odds.  Astoria, Vincennes and Quincy were sunk in the Savo Island debacle.  Northampton and Chicago lost also in later actions in the Solomon’s.  San Francisco and Portland fought toe to toe with the Japanese Battleships Hiei and Kirishima in the epic Naval Battle of Guadalcanal, inflicting so much damage on Hiei that she was later sunk by American Aircraft the following day.  Indianapolis met an unlikely fate at the close of the war being sunk by a Japanese submarine after returning from a secret mission delivering the Atomic bomb.  A series of unfortunate events led to her loss not being noted with the result that most of the survivors of the sinking being lost to the elements and shark attacks while waiting days for rescue.   Others survived horrific damage from “Long Lance” torpedoes and Kamikaze attacks.  Following the war the Pensacola’s were expended as targets and the remaining ships placed in “mothballs” until the late 1950s when all were scrapped.  Some artifacts of San Francisco including her mast are at “Land’s End” park in that city.

uss san franciscoUSS San Fransisco Returning After the  Naval Battle of Guadalcanal

Of all the navies involved only the United States Navy and German Kriegsmarine built or attempted to build new classes of heavy cruisers during the war.  The US Navy brought out the Baltimore Class which was highly successful and built upon lessons learned from the Treaty Cruisers and the follow on Oregon City class which incorporated design improvements based on experience with the Baltimore Class.  Some of these ships would be converted into the first US Guided Missile Cruisers. The later Des Moines Class the largest class of all gun cruisers ever built with fully automated 8″ gun systems.  Of these ships only Salem survives in Quincy MA as a museum ship, sadly the Des Moines which had been slated to become a Museum ship in Milwaukee was scrapped in 2007 .

No treaty cruiser survives today.  Their service, heroic, unceasing and tireless service is remembered only by their surviving crews and a few naval historians and buffs.  The epic damage control actions of the San Francisco are still taught at the Naval Surface Warfare School.  They have passed into history, of those sunk some have been rediscovered, the Ballard expedition discovered and photographed the wrecks of Astoria and Quincy and their Australian consort Canberra in the waters of “Iron Bottom Sound” off Guadalcanal.  The German “Prinz Eugen” though not a treaty cruiser survived the war and was expended as a target in the Atomic bomb tests.  Her wreck lies capsized and submerged at Bikini Atoll.  An attempt to salvage her by a German group was abandoned and one of her screws was brought back and placed on display near Kiel, Germany.

Though all had design drawbacks due to the treaties, the American and British ships performed magnificently and without their service, especially in the early days of the war history today might be different.  Here’s to gallant ships and steadfast crews. May they never be forgotten.

Peace,

Steve+
