German submarine U-268 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II.
Commissioned on 29 July 1942, she served with the 8th U-boat Flotilla for training and later served with the 1st U-boat Flotilla from 1 to 19 February 1943.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-268 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-268 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-268 departed Bergen on 10 January 1943 on her first and only patrol. On 17 January she sank the Norwegian whale factory ship Vestfold, which was laden with 17,386 tons of fuel oil, and three British landing craft - HMS LCT-2239, LCT-2267 and LCT-2344 (each 291 tons) - as deck cargo. Before sinking, Vestfold, which had been abandoned with her engines still running, steamed in circles, almost colliding with another ship.[1]
On 19 February 1943 while returning to her new base in occupied France, U-268 was sunk in the Bay of Biscay, west of Saint Nazaire, at position 47.05°N -61°W by depth charges dropped from a Vickers Wellington bomber of No.172 Squadron RAF. All 44 hands were lost.
U-268 took part in five wolfpacks, namely:
