German submarine U-764 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II.

She was laid down on 1 February 1941 by Kriegsmarinewerft Wilhelmshaven as yard number 147, launched on 13 March 1943 and commissioned on 6 May 1943 under Oberleutnant zur See Hanskurt von Bremen.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-764 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-764 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 {{convert|8.8|cm|in|2|abbr=on}} SK C/35 naval gun, 220 rounds, and two twin {{convert|2|cm|in|sp=us|abbr=on}} C/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 8th U-boat Flotilla on 6 May 1943, followed by active service on 1 November 1943 as part of the 9th Flotilla in Brest, France. On 1 October 1944, she transferred to 11th Flotilla in Bergen, Norway; as the situation worsened in France following the invasion. She remained with 11th Flotilla until her surrender at the end of the war.

In eight patrols she sank one merchant ship, for a total of {{GRT|638|disp=long}}, and 2 warships sunk (1,696 tons).

Wolfpacks

U-764 took part in eight wolfpacks, namely

Eisenhart 3 (9–15 November 1943)
Schill 3 (18–22 November 1943)
Weddigen (22–29 November 1943)
Hinein (26 January – 3 February 1944)
Igel 1 (3–17 February 1944)
Hai 1 (17–22 February 1944)
Preussen (22 February – 13 March 1944)
Dragoner (21–28 May 1944)

Fate

U-764 surrendered on 14 May 1945 at Loch Eriboll, Scotland. She was sunk as a target in position {{coord|56|06|N|09|00|W}} as part of Operation Deadlight on 2 February 1946.
