 The Admiralty accepted that Barracudas were too slow to be effective against the Kaafjord area following the failure of Operation Goodwood . As a result , the task of attacking the battleship was transferred to RAF Bomber Command . The first heavy bomber raid against Kaafjord ( Operation Paravane ) was conducted on 15 September 1944 , with the bombers flying from staging bases in northern Russia . This attack inflicted irreparable damage on Tirpitz , and she was transferred south to the Tromsø area to be used as an immobile coastal defence battery . The battleship was sunk there with heavy loss of life by another Bomber Command raid on 12 November .
