German submarine U-968 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 14 May 1942 by Blohm & Voss, Hamburg as yard number 168, launched on 4 February 1943 and commissioned on 18 March 1943 under Oberleutnant zur See Otto Westphalen.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-968 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[2] She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two Brown, Boveri & Cie GG UB 720/8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[2]
The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph).[2] When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-968 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and one twin 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.[2]
The boat's career began with training at 5th U-boat Flotilla on 18 March 1943, followed by active service on 1 March 1944 as part of the 13th Flotilla for the remainder of her service.
In seven patrols she sank two merchant ships, for a total of 14,386 gross register tons (GRT), damaged one other.
U-968 took part in seven wolfpacks, namely:
U-968 surrendered on 9 May 1945 at Narvik, Norway. She was subsequently transferred to Loch Eriboll in Scotland on 19 May 1945, and later to Loch Ryan as part of Operation Deadlight. She was eventually sunk by Allied forces on 29 November 1945 in the North Atlantic in position 55°24′N 06°22′W / 55.400°N 6.367°W / 55.400; -6.367.
