Landkreuzer P. 1000 Ratte[edit]

A modified version of the 28 cm SK C/28 gun turret was supposed to be the main armament of the German Landkreuzer P. 1000 Ratte, a super-heavy tank design that was never built. The modification consisted of the removal of one of the guns as well as its loading mechanism.
