Sister ship to Bismarck, the Tirpitz had been a thorn in the side of the Allies since its arrival in Norwegian waters in January 1942. The presence of such a powerful battleship so close to the Russian convoy routes required the Royal Navy to keep a large naval force in northern waters, to guard against the threat posed by Tirpitz.
