In January 1943, Tirpitz emerged from the lengthy overhaul, after which she was transferred to Altafjord. Here, she participated in extensive training operations with Scharnhorst and the heavy cruiser Lützow, which lasted until the middle of the year.[65] In early September, Tirpitz, Scharnhorst, and ten destroyers bombarded the island of Spitzbergen, which served as a British refuelling station.
