The Großkampfwagen or "K-Wagen" was a German super-heavy tank, two prototypes of which were almost completed by the end of World War I. The hull of the K-Wagen consisted of six modules that could be transported separately by rail: the control room, the fighting room, the engine room, the transmission room and the two sponsons. The commander could give orders to the crew by means of electric lights: fire control was comparable to that of a destroyer, the Germans seeing the vehicle as a veritable "landship". The drivers would have had to steer the vehicle blindly, directed by the commander. The K-Wagen was to be armed with four 77 mm fortress guns and seven MG08 machine guns and had a crew of 27: a commander, two drivers, a signaler, an artillery officer, 12 artillery men, eight machine gunners and two mechanics.
