VS 80 (submarine)

from Wikipedia, the free encyclopedia

VS 80 , also V 80 , was a test submarine that was built between 1938 and 1940 by the Germania shipyardin Kiel in collaboration with Hellmuth Walter for the German Navy .

history

The test boat (attempt = VS) was an unarmed small submarine, which was intended for a crew of three to five people. The boat was launched on April 14, 1940. It was 22.05 m long and 2.10 m wide, had emerged 3.20 m draft and a total height of 5.65 m. The water displacement was 73 t when surfaced and 85.5 t submerged. The revolutionary drive, which consisted of a Walter turbine system , which developed 2,000 hp at a speed of 20,000 revolutions per minute, was remarkable . During sea trials in 1940 and 1941 in the Schlei and the Putziger Wiek (accompanied by the security ship John Rehder and Polyp ), an underwater speed of 28.1 knots was achieved, a value that was only exceeded by the USS Albacore in 1953 . With the existing supply of 21 t of hydrogen peroxide, the boat could travel up to 50 nautical miles underwater at a speed of 28 knots.

The Navy was enthusiastic about the performance of the test boat. But the Walter drive was still in its infancy in 1940/41 and had not yet been sufficiently developed and tested. The further development of the Walter submarines led to the types XVII, XVIII and XXVI. None of these types was ultimately ripe for the front, but this was less due to the technology and more to the lack of available hydrogen peroxide.

The boat was in late 1942 launched in March 1945 in Hela scuttled.
