German submarine U-656 was a German Type VIIC U-boat built for the Nazi Germany's Kriegsmarine for service during World War II. She was ordered on 9 October 1939 and the keel laid on 4 September 1940. Construction on U-656 was carried out by Hamburg company Howaldtswerke as yard number 805. She was launched on 8 July 1941 and commissioned on 17 September 1941.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-656 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[1] 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 Siemens-Schuckert GU 343/38–8 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).[1]
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).[1] 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-656 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 a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.[1]
U-656 went into service initially with 5th U-boat Flotilla for training from 17 September 1941 until 31 December 1941. She moved into operational service with 1st U-boat Flotilla on 1 January 1942, and was commanded by Kapitänleutnant Ernst Kröning.
U-656 made two patrols, but did not sink any ships. Her first patrol lasted almost two weeks: after departing Kiel on 15 January 1942, she put in at Brest, France on 28 January. The submarine departed Brest on 4 February, but never completed her second patrol. She was sunk with all hands by depth charges dropped by a United States Navy PBO-1 Hudson of Patrol Squadron 82 (VP-82) on 1 March 1942 south of Cape Race, Newfoundland. U-656 became the first U-boat to be sunk by the U.S. Navy in World War II.
