The boat began training on 22 March with the 5th U-boat Flotilla but moved on to the 11th flotilla for operations.
She was one of nine Type VIIs that the Kriegsmarine fitted with an experimental synthetic rubber skin of anechoic tiles known as Alberich, which had been designed to counter the Allies' asdic/sonar devices.
Her remains were positively identified in March 2013 after they were found during oil exploration operations off the coast of Norway, not far from the remains of .
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-486 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-486 was fitted with five torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one SK C/35 naval gun, (220 rounds), one Flak M42 and two twin C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.
Service history
The submarine moved to Horten Naval Base in Norway between 6 and 9 November 1944 and then Egersund, (also in Norway, on the southwest coast, between Stavanger and Kristiansand), arriving there on 20 November.
First patrol
She departed Egersund on her first patrol on 26 November 1944, taking a circuitous route around the British Isles to the Western Approaches. The U-boat claimed her first victim south of the Eddystone Lighthouse by sinking the Silverlaurel on 18 December. She then attacked the on 24 December five miles off the coast of Cherbourg, France. This resulted in the death of over 750 Allied soldiers (819 total deaths). The Leopoldville sank about two hours later. She crippled the US-built but British manned frigate on the 26th. She also sank , another frigate, on the same day.
She was unsuccessfully attacked by a Canadian Vickers Wellington of 407 Squadron, RCAF on 30 December.
She returned to Norway, this time to Bergen, on 15 January 1945.
