German submarine U-645 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II.

She was laid down on 1 December 1941 by Blohm & Voss, Hamburg as yard number 621, launched on 3 September 1942 and commissioned on 22 October 1942 under Leutnant zur See Otto Ferro.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-645 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 Brown, Boveri & Cie GG UB 720/8 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-645 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 one twin {{convert|2|cm|in|sp=us|abbr=on}} C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.{{sfn|Gröner|1991|pp=43-46}}

Service history

This boat's career began with training at 5th U-boat Flotilla on 22 October 1942, followed by active service on 1 May 1943 as part of the 3rd Flotilla for the remainder of her service. In three patrols she sank two merchant ships, for a total of {{GRT|12,788|disp=long}}.

Wolfpacks

U-645 took part in eight wolfpacks, namely

Without name (5–10 May 1943)
Isar (10–15 May 1943)
Donau 1 (15–26 May 1943)
Leuthen (15–24 September 1943)
Rossbach (24 September – 9 October 1943)
Coronel 2 (13–14 December 1943)
Coronel 3 (14–17 December 1943)
Borkum (18–24 December 1943)

Fate

U-645 was sunk on 24 December 1943 in the North Atlantic in position {{coord|45|20|N|21|40|W}}, by depth charges from {{USS|Schenck|DD-159|6}}. All hands were lost.
