The LK I was a German light tank that was designed to be simple and easy to produce.
Its designer was Joseph Vollmer. Vollmer also had a hand in the creation of the A7V Sturmpanzer-Kraftwagen.
Designed in 1918, the LK I, or Leichte Kampfwagen I, had a layout like that of a typical car. It had the chassis of a Daimler car. The car’s axles were used in the tank’s sprocket and idler wheels.
The LK I carried a crew of three men. It weighed almost seven tons. It had a single weapon – a 0.312 inch (7.92 mm) machine gun.

The Armistice took place before the LK I could see active service. Therefore, it only existed as a prototype.
