This caused 1,500 t (1,500 long tons; 1,700 short tons) of water to flood the ship; Tirpitz had again been disabled.[69] A month later, on 15 October, Tirpitz was moved to Håkøya Island off Tromsø to be used as a floating artillery battery. Two weeks later, on 29 October, the British launched Operation Obviate, which consisted of 32 Lancaster bombers. Only a near miss was achieved, though it caused Tirpitz to take in more water.
