German submarine U-482 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down on 13 February 1942 at Deutsche Werke in Kiel as yard number 317 and went into service on 1 December 1943 under the command of Hartmut Graf von Matuschka, Freiherr von Toppolczan und Spaetgen.^[1]

U-482 began her service by training with the 5th U-boat Flotilla. She then transferred to the 9th, followed by the 11th flotillas.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-482 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.^[3] She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two Siemens-Schuckert GU 343/38–8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).^[3]

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph).^[3] When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-482 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, (220 rounds), one 3.7 cm (1.5 in) Flak M42 and two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.^[3]

Service history

U-482 carried out two war patrols from Bergen in Norway, having sailed briefly to Horten Naval Base (also in Norway), both under Matuschka's command. The first, which began on 14 August 1944, took U-482 off the coast of Ireland. Over a nine-day period, she sank two freighters, the two tankers Jacksonville and Empire Heritage as well as the British corvette HMS Hurst Castle for a total of 31,611 gross register tons (GRT) and 1,010 tons. It was the single most successful war patrol by a Type VII U-boat in 1944.^[2]^[4]

U-482 mounted a second patrol beginning 18 November, but was sunk with all hands a week later by the British frigate HMS Ascension

Fate

During the war it was thought that the U-482 was not sunk until 16 January 1945, and that she had damaged the escort carrier HMS Thane (later determined to be the work of U-1172). Credit for her sinking was given to the ships of British Support Group 22. In the 1990s the British Admiralty revised that assessment and declared that U-482 had possibly struck a mine in the North Channel, off Malin Head, in early December 1944.^[4] In 2005 U-boat researcher Axel Niestlé determined that U-482 was probably sunk by the British frigate HMS Ascension west of the Shetland Islands on 25 November 1944.^[1]
