Comparing: SU-152 vs. Krupp-Steyr Waffenträger

Development of a tank destroyer on the basis of the KV-1S heavy tank began on January 4, 1943. The vehicle received the designation KV-14 (Object 236). A prototype underwent field trials at the beginning of February 1943 and entered service on February 14, 1943. In April, the KV-14 was renamed SU-152. By December 1943, 670 vehicles were manufactured. Thanks to its ability to successfully combat German Tiger I and Panther tanks, the SU-152 was dubbed "Hunter" by the troops.

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.
