She sank no ships.She was a member of eight wolfpacks.She was sunk by British warships, near Murmansk on 17 February 1945.German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-425 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10\u00a0m (220\u00a0ft 2\u00a0in), a pressure hull length of 50.50\u00a0m (165\u00a0ft 8\u00a0in), a beam of 6.20\u00a0m (20\u00a0ft 4\u00a0in), a height of 9.60\u00a0m (31\u00a0ft 6\u00a0in), and a draught of 4.74\u00a0m (15\u00a0ft 7\u00a0in). 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\u00a0kW; 2,760 to 3,160\u00a0shp) for use while surfaced, two Siemens-Schuckert GU 343\/38\u20138 double-acting electric motors producing a total of 750 metric horsepower (550\u00a0kW; 740\u00a0shp) for use while submerged. She had two shafts and two 1.23\u00a0m (4\u00a0ft) propellers. The boat was capable of operating at depths of up to 230 metres (750\u00a0ft).The submarine had a maximum surface speed of 17.7 knots (32.8\u00a0km\/h; 20.4\u00a0mph) and a maximum submerged speed of 7.6 knots (14.1\u00a0km\/h; 8.7\u00a0mph). When submerged, the boat could operate for 80 nautical miles (150\u00a0km; 92\u00a0mi) at 4 knots (7.4\u00a0km\/h; 4.6\u00a0mph); when surfaced, she could travel 8,500 nautical miles (15,700\u00a0km; 9,800\u00a0mi) at 10 knots (19\u00a0km\/h; 12\u00a0mph). U-425 was fitted with five 53.3\u00a0cm (21\u00a0in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8\u00a0cm (3.46\u00a0in) SK C\/35 naval gun, 220 rounds, and two twin 2\u00a0cm (0.79\u00a0in) C\/30 anti-aircraft guns.

She was reassigned to the 11th flotilla on 1 January 1944, then the 13th flotilla on 15 September of that year.First patrol[edit]U-425‘s first patrol began with her departure from Kiel on 20 November 1943. Having cleared the Kattegat and Skagerrak, the boat followed the Norwegian coast to Bergen; arriving there on the 25th.Second patrol[edit]The submarine criss-crossed the Norwegian and Barents Seas between the North Cape and Bear Island before docking in Hammerfest on 2 February 1944.Third and fourth patrols[edit]The boat’s third and fourth patrols were relatively uneventful; the latter following short trips from Hammerfest to Bergen, to Narvik. The patrol itself was carried out between Jan Mayen and Bear Islands.Sixth, seventh, eighth and ninth patrols and loss[edit]A regular pattern then emerged between Hammerfest and Narvik. Part of her sixth sortie took U-425 as far north and east as the southern end of Novaya Zemlya in the Pechoskoye More.[4]The boat was sunk by depth charges dropped by the British sloop HMS\u00a0Lark and the corvette HMS\u00a0Alnwick Castle near Murmansk on 17 February 1945.Wolfpacks[edit]U-425 took part in eight wolfpacks, namely:Isegrim (1 \u2013 27 January 1944)Werwolf (29 January \u2013 1 February 1944)Werwolf (7 \u2013 27 February 1944)Trutz (13 May \u2013 6 June 1944)Dachs (31 August \u2013 3 September 1944)Grimm (15 September \u2013 1 October 1944)Panther (17 October \u2013 10 November 1944)Rasmus (6 \u2013 13 February 1945)References[edit]Bibliography[edit]Busch, Rainer; R\u00f6ll, Hans-Joachim (1999).
