German submarine U-825 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II.

She was laid down on 19 July 1943 by Schichau-Werke, Danzig as yard number 1588, launched on 16 February 1944 and commissioned on 4 May 1944 under Oberleutnant zur See Gerhard Stoelker.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-825 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-825 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), one {{convert|3.7|cm|in|abbr=on}} Flak M42 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 Flotilla on 4 May 1944, followed by active service on 1 December 1944 as part of the 11th Flotilla.

Wolfpacks

U-825 took part in no wolfpacks.

Fate

U-825 surrendered on 13 May 1945 at Loch Eriboll. She was then sunk on 3 January 1946 at {{coord|55|31|N|07|30|W|display=inline, title}} as part of Operation Deadlight.
