Tirpitz in Fættenfjorden 1942, with Langstein in the background

Fættenfjorden is a sidearm of the Trondheimsfjord northeast of the city of Trondheim in Nord-Trøndelag county, Norway. The fjord is located on the border of the municipalities of Stjørdal and Levanger.

The German battleship Tirpitz was moored here from 16 January 1942 to 2 July 1942. During this time the Royal Air Force attacked the Tirpitz four times with limited success. Due to the heavy amount of anti-aircraft weaponry, both on the ship and in the surrounding area, the RAF lost 17 airplanes and 64 crew members in the attempts.
