Operation Paravane was a British air raid of World War II that inflicted heavy damage on the German battleship Tirpitz, at anchor in Kaafjord in the far north of German-occupied Norway. The attack was conducted on 15 September 1944 by 21 Royal Air Force heavy bombers, which flew from an airfield in the north of the Soviet Union. The battleship was struck by one bomb, and further damaged by several near misses. This damage rendered Tirpitz unfit for combat, and she could not be repaired as it was no longer possible for the Germans to sail her to a major port.
