Summary
German submarine U-481 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 6 February 1943 at the Deutsche Werke yard in Kiel, launched on 25 September 1943, and commissioned on 10 November 1943 under the command of Oberleutnant zur See Ewald Pick.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-481 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-481 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.
U-481 left Kiel on 19 June 1944 under the command of Kapitänleutnant Klaus Andersen, and sailed to Reval (now Tallinn, Estonia) via Helsinki. She departed Reval on her first war patrol on 5 July and sailed east into the Gulf of Finland to Soviet waters. On 30 July she attacked a group of Soviet Navy coastal minesweepers with torpedoes, sinking two (KT-804 and KT-807) and damaging another (KT-806). On the same day the U-boat was attacked while in Narva Bay by two Ilyushin Il-2 Shturmovik aircraft from the 35th Assault Air Regiment (35. ShAP), and managed to damage one enough to force the pilot to ditch his aircraft. The U-boat arrived back at Reval on 4 August.
