LK-III was to be an improved and redesigned version of LK-II tank with front mounted turret and rear mounted engine. It was to be no longer based on Daimler car chassis but on specially designed components. The main armament was to be either Russian 57mm Sokol gun or 20mm Becker Flieger Kanone. 1000 were ordered but not even the prototype was completed before November of 1918.
