      • German submarine U-750 was a German Type VIIC submarine U-boat built for Nazi Germany's Kriegsmarine for service during World War II.


      Design


      German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-750 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 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).
      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-750 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 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


      Work on U-750 began on 29 September 1942 as yard number 1560 of the F Schichau GmbH in the former Free City of Danzig. She was commissioned on 26 August 1943, under the command of Tenente di vascello Emerico Siriani and trained with the 8th U-boat Flotilla until 8 September 1943. On 29 September 1943 however, Emerico Siriani was replaced by Oberleutnant zur See Georg von Bitter, then on 1 September 1944 by Oberleutnant zur See Justus Grawert, who would command her for the rest of her service career.
      On 1 April 1945, U-750 was moved to the 5th U-boat Flotilla, but remained as a training boat until she was scuttled on 5 May 1945.
