German submarine U-287 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 8 August 1942 at the Bremer Vulkan yard at Bremen-Vegesack as yard number 52. She was launched on 13 August 1943 and commissioned on 22 September under the command of Oberleutnant zur See Heinrich Meyer. She did not sink or damage any ships.
Official records report that she was sunk by a mine in May 1945 in the Elbe estuary. But late interviews with crew members support that she was scuttled. According to these sources[1] the remaining four crew members convinced British investigators they were struck by a mine. This version avoided the whole crew for being charged for destroying the sub which was supposed to be handed over to allies forces according to German Instrument of Surrender.[2]
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-287 had a displacement of 769t when at the surface and 871t while submerged. She had a total length of 67.1m (220.1feet), a pressure hull length of 50.5m (165.7feet), a beam of 6.2m (20.3feet), a height of 9.6m (31.5feet), and a draught of 4.74m (15.55feet). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of NaNPS for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750PS for use while submerged. She had two shafts and two 1.23abbr=onNaNabbr=on propellers. The boat was capable of operating at depths of up to .
The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-287 was fitted with five 53.30NaN0 torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.82NaN2 SK C/35 naval gun, 220 rounds, and two twin 2sp=usNaNsp=us C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.
U-287 served with the 24th U-boat Flotilla for training from September 1943 to February 1945 and operationally with the 31st flotilla from 1 March.
The boat's only patrol was preceded by two short voyages from Kiel in April 1945 to Horten Naval Base and Kristiansand in Norway (the former being located northeast of Kristiansand).[3]
The boat departed Kristiansand on 29 April 1945 and was stayed in the Elbe estuary. The whole crew but four evacuated on lifeboats to Altenbruch before the remaining crew scuttled the ship near Schelenkuhlen in the Elbe river on 16 May. They testified that they were sunk by a mine, which was documented as the official reason of loss.
