Operation Source was a series of attacks to neutralise the heavy German warships – Tirpitz, Scharnhorst, and Lützow – based in northern Norway, using X-class midget submarines.

The attacks took place in September 1943 at Kåfjord and succeeded in keeping Tirpitz out of action for at least six months.
