The Leichter Kampfwagen II (English: light combat car) or "LK II" was a development of the LK I with the same layout, but incorporating a rotating turret on the rear superstructure armed with a 37mm Krupp or Russian 57mm Sokol gun. Its armor was 8 to 14mm thick, which increased its total weight to 8.75 tons. Power was provided by a Daimler-Benz Model 1910 4-cylinder 55-60 hp gasoline engine, giving a maximum speed of 14 to 18 km/h with range of 65–70 km.A version armed with one or two 7.92mm Maxim 08/15 machine guns was also planned but progressed no farther than a project.Only two prototypes were produced by June 1918, and were followed by orders for 580 tanks, which were never completed.
