In late September 1943, a British midget submarine raid planted explosives near Tirpitz, causing serious shock damage when they exploded. In February 1944, while she was under repair, the German battleship was the target of a raid by Soviet bombers that produced one near-miss. In early April, as her repairs were completing, Tirpitz was attacked by British carrier-based planes, receiving several hits and serious damage and casualties. Further repairs lasted until June, and she was again attacked by British planes in July and August, though the resulting damage was not serious. In mid-September, she was hit in the bow by very heavy bombs dropped by Royal Air Force heavy bombers. Moved to Tromsø in October, she was the target of further raids. Finally, on 12 November, Tirpitz was hit and near-missed by several very heavy bombs, causing massive damage. She listed heavily, suffered an ammunition explosion and rolled over. Her wreck was largely scrapped in place after the war.
