German submarine Wilhelm Bauer (originally designated U-2540) is a Type XXI U-boat of Nazi Germany's navy (Kriegsmarine), completed shortly before the end of World War II. It was scuttled at the end of the war, having never gone on patrol. In 1957, it was raised from the seabed off Flensburg Firth, refurbished, and recommissioned for use by the West-German Bundesmarine in 1960. Finally retired fully in 1983, it is the only floating example of a Type XXI U-boat. It has been modified to appear in wartime configuration and exhibited at the German Maritime Museum in Bremerhaven, Germany.^[2]
