Comparing: SU-100M1 vs. ISU-152 vs. Object 416

Developed at the UHMP (Ural Heavy Machinery Plant) on the basis of the T-34-85. The fighting compartment was located in the rear. The vehicle superceded by the SU-100M-2, based on the basis of the T-44, and never manufactured.

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.

The development of the Object 416 started at the Construction Bureau of Factory No. 75 in the fall of 1949. The blueprint was developed by March 1950. Due to technical problems with the turret, a working prototype was not ready until April 1952. Improvements were made, and another prototype was built in the summer of 1953, but the vehicle never entered mass production.
