Kugelpanzer concrete tank 3D model

After the First World War, unique concepts to deal with the No Man’s Land issue came by the bucketload. One of more unique ideas being the rolling or ball tank. The Germans were the first to try a working prototype with the Treffas-Wagen in 1917. Another concept came in 1936 with the “Tumbleweed tank”, designed by the Texan inventor A.J. Richardson. It never left the drawing board.

Listed as Item #37 in the Kubinka tank museum, the Kugelpanzer, or Rollzeug (literally meaning “ball tank” and ”rolling vehicle”), is visually similar to its Treffas-Wagen predecessor. It is the only known built example of one of these ball-tanks still in existence. It is a rarity among military vehicles.

The vehicle was captured by the Red Army. The most commonly believed theory is that at some point in the 1940s it was sent to Japan as part of Germany’s technology sharing scheme, and was captured in 1945 in Manchuria. However, another report states that it was captured at the Kummersdorf proving grounds along with the infamous Maus.
