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

were preceded by the shorter Type VIIB submarines. U-482 had a displacement of when at the surface and while submerged. She had a total length of, a pressure hull length of, a beam of, a height of, and a draught of. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of for use while surfaced, two Siemens-Schuckert GU 343/38–8 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to.
The submarine had a maximum surface speed of and a maximum submerged speed of. When submerged, the boat could operate for at ; when surfaced, she could travel at. U-482 was fitted with five torpedo tubes, fourteen torpedoes, one SK C/35 naval gun,, one Flak M42 and two twin C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.

Service history

U-482 carried out two war patrols from Bergen in Norway, having sailed briefly to Horten Naval Base, 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 for a total of. It was the single most successful war patrol by a Type VII U-boat in 1944.
U-482 mounted a second patrol beginning 18 November, but was sunk with all hands a week later by the British frigate

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 . 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. In 2005 U-boat researcher Axel Niestlé determined that U-482 was probably sunk by the British frigate west of the Shetland Islands.
