German submarine U-847

German submarine U-847 was a long-range Type IXD2 U-boat built for Nazi Germany's Kriegsmarine during World War II. Laid down in Bremen and launched on 5 September 1942. She was equipped with two stern torpedo tubes and 24 mines.

She was commanded for her short career by four Knight’s Cross recipients, each a U-boat ace in their own right, although she neither sank nor damaged any vessels. They were:-
 * Kapitänleutnant Friedrich Guggenberger
 * Korvettenkapitän Wilhelm Rollmann
 * Kapitänleutnant Jost Metzler
 * Kapitänleutnant Herbert Kuppisch

She joined 4th Flotilla for training on 23 January 1943, where she remained until 30 June 1943. She then joined 12th Flotilla for active service until 27 August 1943 when she was sunk while providing logistical support for other u-boats operating in the area.
