The Type VIIC U-Boat: The Workhorse of the German Navy

Das Boot 

Friends of Padre Steve’s World,

The beginning of this week has been really busy with something unexpected at work that took up much of my day caring for some of my co-workers. Nobody died or anything like that, but it was pretty traumatic and I am not the person to write about it, though I expect that Thomas Ricks may do so soon. That being said, as always there is much to write about but after today I am kind of taking it easy, besides, Donald Trump’s antics are getting pretty boring as he continues to implode as a serious candidate for President, as are the machinations of the GOP House members, the gang who could’t shoot strait, who are trying once again to torpedo Hillary Clinton. Sorry, but after five years they remind me of Wile E. Coyote trying to get the Road Runner, simply boring. 

So tonight something not very controversial but interesting. Those that know me and have been following my writings from the beginning know that I am fascinated with warships. Today, and the next few days I am going to republish some very old articles about three important types of German U-Boats in the Second World War. Tonight, an article on the Type VII U-Boat, the workhorse of the German Navy during the Battle of the Atlantic, and a tribute to the brave sailors who served aboard them, most of who never returned home.

Have a great night.

Peace

The signature warship of the German Kreigsmarine of the Second World War has to be the U-Boat Type VIIC, the most numerous type of submarine ever produced by any Navy. 568 of these U-Boats would be commissioned beutween 1940 and 1945 as well as 91 of the Type VIIC/41. The Type VIIC was developed from the prewar Type I and Type VIIA and VIIB classes.

Compared to contemporary American submarines of the Gato class they were smaller, mounted fewer torpedo tubes and had a shorter range. However the American boats were designed for the vast expanse of the Pacific while the German boats for the most part were operated in the smaller confines of the Atlantic and Mediterranean.

The boats displaced a mere 769 tons on the surface and 871 tons submerged and were 67.1 meters (220.14 feet) long. The boats had a single pressure hull and the VIIC could dive to a maximum depth of 230 meters (754 feet) and had a crush depth of 250-295 meters (820-967 feet). The VIIC/41 could dive to 250 meters or 820 feet and a crush depth of 275-325 meters (902-1066 feet). This was deeper than any allied submarines of the period and a testament to their sound construction.

The Type VIICs were armed with a C35 88 mm/L45 gun with 220 rounds for surface actions and various types and numbers of anti-aircraft guns. The standard configuration for torpedo tubes was 4 bow mounted tubes and 1 stern mounted tube although a small number only carried 2 forward and none aft. They carried a maximum of 14 torpedoes and could carry 26 TMA Mines which would be laid at approaches to various ports.

The Type VIIC was powered by two supercharged Germaniawerft, 6 cylinder, 4-stroke M6V 40/46 diesel engines on the surface producing between 2,800 to 3,200 horsepower which gave the boats a 17.7 knot maximum speed on surface. For submerged operations the boats were powered by one of a number of different electric motors whose batteries were charged by the diesels. The electric motors produced 750 horsepower (560 kW) and could drive the boats a maximum of 7.6 knots. In 1944 many of the surviving boats were equipped with the schnorkel apparatus which allowed them to use their diesel engines underwater at shallow depths. The had a range of 8190 miles at 10 knots surfaced which gave them a decent amount of operational flexibility for their Atlantic operations.

During the war the German U-Boat force suffered grievous losses many of which were Type VIICs. The VIICs performed excellently in combat and many survived engagements that would have sunk less tough boats. The most famous of the Type VIICs of all variants is probably the U-96 which was featured in the epic submarine film Das Boot. A number had post war careers in several navies and the last active VIIC the U-573 which served in the Spanish Navy as the G-7 was decommissioned in 1970 and sold for scrap over the objections of those that wanted to purchase her as a memorial. The only surviving Type VIIC is the U-995 at Laboe Germany where she is a memorial to all the U-Boat Sailors of the Second World War. Two full sized mock ups one for exterior scenes and one for interior scenes were constructed for Das Boot and the exterior mock up was also used in Raiders of the Lost Ark.

The Enemy Below

 

During the war U-Boats of all types sank nearly 3000 Allied ships including 175 warships among which were the carriers HMS Glorious, HMS Ark Royal and HMS Eagle and the Battleships HMS Barham and HMS Royal Oak. The Germans lost nearly 800 U-Boats of all types and over 28,000 U-Boat Sailors, about 75% of the force.

The films Das Boot and The Enemy Below are excellent reminders of the courage of the men that operated these submarines during the war. Though the Nazi Regime was evil the men of the U-Boat Service often displayed courage and ingenuity in the face of overwhelming odds and they nearly won the war for the Germans.

    The Kriegsmarine U-Boat Navy definitely fought some fiercely contested battles in WW2. Highly trained and brave to a fault (Geeeze man, that 70% plus casualty rate!!!), it’s interesting that the German sailors just weren’t very good Nazis. A closer look at the Laconia Incident provides compelling evidence of the war the German Navy probably wanted to fight. This always made them a little suspect by the German high command, and may have kept them out of the best pickings for resources and war materiel. This is a good thing! As those U-Boats, even in the relatively limited numbers they had, really wrecked the allied shipping lanes. Whew…. if Germany had put in the kind of resources Doenitz wanted for his U-Boats, World War II may have ended very differently.
