[edit] History
Her keel was laid down 21 November 1939, by Blohm + Voss of Hamburg. She was commissioned 23 December 1940, with Kapitänleutnant Karl Thurmann in command. Thurmann commanded her for her entire career.
On 25 April 1941 major engine trouble forced U-553 to return to base.
On 20 January 1943, U-553 sent a radio message: "Sehrohr unklar" (periscope unready for action), and was never heard from again. She had suffered no casualties to her crew until lost with all hands.
