German_submarine_U-571--Erwin_Meierdress

German submarine U-571 was a Type VIIC U-boat built for the Kriegsmarine of Nazi Germany for service during World War II. U-571 conducted eleven war patrols, sinking five ships totalling 33,511 gross register tons (GRT), and damaging one other for 11,394 GRT. On 28 January 1944 she was attacked by an Australian-crewed Sunderland aircraft from No. 461 Squadron RAAF west of Ireland and was destroyed by depth charges. All hands were lost.
The fictional 2000 U.S. war film U-571 has no relation to this U-boat, but is very loosely based on the British capture of U-110 and her Enigma and cipher keys.
