Comparing: AT 7 vs. Krupp-Steyr Waffenträger

Conceived as an assault breakthrough tank, this design was completed by June 10th, 1943. No complete prototypes were built. However, some parts and components of the AT7 were used in the A39 Tortoise.

A vehicle project by Steyr as a special artillery transporter that would be able not only to transport the gun but also to fire it from the chassis. To keep costs down and reduce complexity, the design used many components of the Raupenschlepper Ost, a tracked artillery mover. The turret and gun were supplied by Krupp. One wooden model and one prototype were manufactured by September 2, 1944.
