Comparing: Rhm.-Borsig Waffenträger vs. ISU-152

Developed by the Rheinmetall-Borsig company and designed as a special artillery carrier. The vehicle was designed to carry an artillery system as well as to fire from the chassis. The vehicle utilized the suspension of the Hetzer tank destroyer. Development continued from the end of 1942 through the middle of 1944. However, the project was discontinued in favor of the Ardelt project because of a complicated design, high cost, and excessive weight.

Developed on the basis of the IS tank. The ISU-152 was conceived as a replacement for the SU-152, which was based on the KV-1s chassis. A total of 4,635 vehicles were built from November 1943 through June 1945.
