U-37

German submarine U-37 was a Type IXA U-boat of Germany's Kriegsmarine during World War II. The submarine was laid down on 15 March 1937 at the DeSchiMAG AG Weser yard in Bremen, launched on 14 May 1938, and commissioned on 4 August 1938 under the command of Kapitänleutnant Heinrich Schuch as part of the 6th U-boat Flotilla. Between August 1939 and March 1941, U-37 conducted eleven combat patrols, sinking 53 merchant ships, for a total of 200,124 gross register tons (GRT); and two warships, the British Hastings-class sloop HMS Penzance, and the French submarine Sfax (Q182). U-37 was then withdrawn from front-line service and assigned to training units until the end of the war. On 8 May 1945 the U-boat was scuttled in Sonderburg Bay, off Flensburg. U-37 was the sixth most successful U-boat in World War II.
