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 {{convert|769|t|LT}} when at the surface and {{convert|871|t|LT}} while submerged.{{sfn|Gröner|1991|pp=43-46}} She had a total length of {{convert|67.10|m|ftin|abbr=on}}, a pressure hull length of {{convert|50.50|m|ftin|abbr=on}}, a beam of {{convert|6.20|m|ftin|abbr=on}}, a height of {{convert|9.60|m|ftin|abbr=on}}, and a draught of {{convert|4.74|m|ftin|abbr=on}}. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of {{convert|2800 to 3200|PS|kW shp|-1}} for use while surfaced, two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of {{convert|750|PS|kW shp}} for use while submerged. She had two shafts and two {{convert|1.23|m|ft|abbr=on|0}} propellers. The boat was capable of operating at depths of up to {{convert|230|m}}.{{sfn|Gröner|1991|pp=43-46}}

The submarine had a maximum surface speed of {{convert|17.7|kn}} and a maximum submerged speed of {{convert|7.6|kn}}.{{sfn|Gröner|1991|pp=43-46}} When submerged, the boat could operate for {{convert|80|nmi}} at {{convert|4|kn}}; when surfaced, she could travel {{convert|8500|nmi}} at {{convert|10|kn}}. U-775 was fitted with five {{convert|53.3|cm|in|0|abbr=on}} 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), one 3.7 cm Flak 18/36/37/43 and two twin 2 cm FlaK 30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.{{sfn|Gröner|1991|pp=43-46}}

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 {{GRT|1,926|disp=long}}, 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.
