German submarine U-775 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 22 January 1943 by Kriegsmarinewerft Wilhelmshaven as yard number 158, launched on 11 February 1944 and commissioned on 23 March 1944 under Oberleutnant zur See Erich Taschenmacher.
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-775 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. 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 Garbe, Lahmeyer & Co. RP 137/c 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).
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). 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-775 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), one 3.7 cm (1.5 in) Flak M42 and two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.
Service history
The boat's career began with training at 31st U-boat Flotilla on 23 March 1944, followed by active service on 1 November 1944 as part of the 11th Flotilla for the remainder of her service.
In two patrols she sank one merchant ship, for a total of 1,926 gross register tons (GRT), one warship sunk (1,300 tons) and one merchant ship damaged (6,991 GRT).
Wolfpacks
U-775 took part in no wolfpacks.
Fate
U-775 surrendered on 9 May 1945 in Trondheim, Norway. She was later sunk by gunfire on 8 December 1945 as part of Operation Deadlight.
