You are right, Hagar, the Tirpitz was eventually sunk by Lancasters of 617 Sqdn RAF. Here is a snippet from the Fleet Air Arm archives :
"On 30 March 1944, HMS Furious and HMS Victorious of the Home Fleet sailed from Scapa Flow in company with a powerful force of battleships and escort carriers, in Operation Tungsten. Their objective was to attack the German battleship Tirpitz, Germany's last surviving heavy surface unit, moored in the supposedly impregnable anchorage of Altenfjord in northern Norway.
In the early hours of 3 April, having approached to within 120 miles of the Norwegian coast, the carriers launched 42 dive-bombers and 80 fighters in the largest air strike yet undertaken by the Fleet Air Arm.
Tirpitz lay in Kaafjord and was hit by 15 bombs and badly crippled, and although not sunk, was incapable of putting to sea for several months during the crucial Normandy D-Day invasion period of the Allies."
