Maritime History
German submarine U-521 was a Type IXC U-boat of Nazi Germany's Kriegsmarine during World War II. She was built by the Deutsche Werft yard at Finkenwerder, Hamburg with yard number 336. Commissioned in June 1942, she was commanded by Kapitänleutnant Klaus Bargsten. The U-boat was assigned to the 4th U-boat Flotilla for training and the 2nd flotilla for operations. U-521 was sunk on 2 June 1943 by the submarine chaser USS Gilmer. The only survivor was Bargsten himself. This was the second boat under Bargsten's command, and the first that suffered heavy losses. The wreck of the submarine has never been found.
