On 12 November 1944, RAF Bomber Command dispatched 30 Avro Lancaster heavy bombers from No. 9 Squadron RAF and No. 617 Squadron RAF (including a film unit aircraft from No. 463 Squadron of the Royal Australian Air Force) from RAF Lossiemouth to Tirpitz's mooring in Tromsø, Norway. Each bomber carried a single 5.4-ton Tallboy bomb.
At least two bombs hit Tirpitz, which suffered a violent internal explosion. The battleship capsized and remained bottom upwards. Approximately 1,000 of the 1,900 men on board were killed or injured.
The destruction of Tirpitz meant that the threat from German surface ship attack against the Allied Arctic convoys supplying the Soviet Union was considerably lessened, and several British capital ships could therefore be moved from the Atlantic to support the war in the Pacific.
