German submarine U-874

German submarine U-874 was a long-range Type IXD2 U-boat built for Nazi Germany's Kriegsmarine during World War II.

She was ordered on 25 August 1941, and was laid down on 17 March 1943 at DeSchiMAG AG Weser, Bremen, as yard number 1082. She was launched on 21 December 1943 and commissioned under the command of Oberleutnant zur See Theodor Petersen on 8 April 1944.

Design
German Type IXD2 submarines were considerably larger than the original Type IXs. U-874 had a displacement of 1610 t when at the surface and 1799 t while submerged. The U-boat had a total length of 87.58 m, a pressure hull length of 68.50 m, a beam of 7.50 m, a height of 10.20 m, and a draught of 5.35 m. The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines plus two MWM RS34.5S six-cylinder four-stroke diesel engines for cruising, producing a total of 9000 PS for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1000 shp for use while submerged. She had two shafts and two 1.85 m propellers. The boat was capable of operating at depths of up to 200 m.

The submarine had a maximum surface speed of 20.8 kn and a maximum submerged speed of 6.9 kn. When submerged, the boat could operate for 121 nmi at 2 kn; when surfaced, she could travel 12750 nmi at 10 kn. U-874 was fitted with six 53.3 cm torpedo tubes (four fitted at the bow and two at the stern), 24 torpedoes, one 10.5 cm SK C/32 naval gun, 150 rounds, and a 3.7 cm with 2575 rounds as well as two 2 cm anti-aircraft guns with 8100 rounds. The boat had a complement of fifty-five.

Service history
On 9 May 1945, U-874 surrendered at Horten, Norway. She was later transferred to Lisahally, Northern Ireland on 29 May 1945. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-874 was one of 116 selected to take part in Operation Deadlight. U-874 was towed out on 31 December 1945, and sunk.

The wreck is located at 55.78333°N, -9.45°W.
