German submarine U-750

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 t when at the surface and 871 t while submerged. She had a total length of 67.10 m, a pressure hull length of 50.50 m, a beam of 6.20 m, a height of 9.60 m, and a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2800 to 3200 PS for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 PS for use while submerged. She had two shafts and two 1.23 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 17.7 kn and a maximum submerged speed of 7.6 kn. When submerged, the boat could operate for 80 nmi at 4 kn; when surfaced, she could travel 8500 nmi at 10 kn. U-750 was fitted with five 53.3 cm torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm SK C/35 naval gun, 220 rounds, and two twin 2 cm 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.
