German submarine U-854

German submarine U-854 was a Type IXC/40 U-boat built for Nazi Germany's Kriegsmarine during World War II.

U-854 was ordered in June 1941 from DeSchiMAG AG Weser in Bremen under the yard number 1060. Her keel was laid down on 29 September 1942 and the U-boat was launched the following year on 5 April 1943. She was commissioned into service under the command of Kapitänleutnant Horst Weiher (Crew 36) in 4th U-boat Flotilla.

While training in the Baltic Sea, U-854 rescued survivors of GS U-983 on 9 September 1943 and brought them to Hela. On 4 February 1944 the U-boat was on its way back to Swinemünde, when she struck a mine - one of a barrage 'Geranium', that had been laid by the British Royal Air Force. 51 crew members died, seven survived.
