406 mm. Schnellladekanone C/34

This gun was developed in 1934 by Gustav Krupp and should be the main armament for the new German battleship classes H and J. This battleship class was a continuing vocational development of the smaller Bismarck Class, were both Bismarck and Tirpitz belonged. It was planned to build six ships in the new class, but in 1941 the plans were changed and no ships were ever completed.

The guns thereby came in profits and was instead used as armament in the atlantic wall. Three of the guns were sent to the gun battery Schleswig-Holstein on the peninsula of Hel in Poland, but already in 1942, they were packaged together and sent on to the gun battery Lindemann at the French city of Calais.

Seven guns were sent to Norway four guns to gun battery Trondenes, northwest of Narvik and tree guns to gun battery Dietl southwest of Narvik.

The gun barrel measured approximately 20 meters and the standard shells weighed 1000 kg. With a special grenade of 600 kg. a range of 56 km. was achieved. This range was at the battery in Calais enough to engage targets in southeastern England. The guns were protected by an armored turret, just as if they were on a battleship.
