German submarine U-291 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

The submarine was laid down on 17 October 1942 at the Bremer Vulkan yard at Bremen-Vegesack as yard number 56. She was launched on 30 June 1943 and commissioned on 4 August under the command of Oberleutnant zur See Hans Keerle.[1]

She carried out no patrols and did not sink or damage any ships.

The boat surrendered in May 1945 at Cuxhaven. She was sunk as part of Operation Deadlight in December.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-291 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[3] 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 AEG GU 460/8–27 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).[3]

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).[3] 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-291 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 an anti-aircraft gun. The boat had a complement of between forty-four and sixty.[3]

Service history

U-291 served with the 21st U-boat Flotilla for training from 4 to 31 August 1943 and was a Trials boat with the 23rd flotilla from 1 September 1943 until 1 July 1944. She then worked as a 'school' boat from 1 July 1944 to 28 February 1945 with the 21st flotilla once more. Her last assignment was with the 31st flotilla from 1 March to 8 May 1945.

The submarine capitulated at Cuxhaven on 5 May 1945. She was transferred from Wilhelmshaven to Loch Ryan in Scotland for Operation Deadlight on 24 June and was sunk by the guns of HMS Onslaught[4] off Northern Ireland on 20 December.
