Service history

First patrol

''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.

Second patrol

''U-481'' sailed again from Reval on 10 August 1944, and patrolled Soviet waters with no success, before arriving at Königsberg in East Prussia, on 21 August.

Third patrol

Departing Königsberg on 16 September 1944, the U-boat patrolled the Baltic, and on 15 October sank three small Finnish Galeas sailing barges (''Dan'', ''Endla'' and ''Maria'') off Osmussaar, Estonia, with shell-fire, before arriving at Danzig (now Gdansk) on 26 October.

Fourth patrol

''U-481'' sailed from Danzig on 2 November 1944, returning to the Gulf of Finland, and on 9 November off Cape Pakri she torpedoed and shelled the Soviet 1,000 GRT barge ''112600'', sinking her. On 28 November she sank the Soviet 108 tons coastal minesweeper ''T-387'' in the same area. The U-boat returned to Danzig on 22 December.

Fifth patrol

After returning to Kiel to be fitted with a ' schnorchel' in February 1945, the U-boat sailed for Horten Naval Base in Norway, making her final patrol along the Norwegian coast from 7 April to 4 May, finally arriving at Narvik only a few days before the German surrender. On 12 May all U-boats in the Narvik area were ordered by the Allies to sail to Skjomenfjord. Later transferred to Loch Ryan, ''U-481'' was sunk at position in as part of "Operation Deadlight" on 30 November 1945.
