A draft project of a heavy tank destroyer, developed in 1947–1948 under the influence of the Jagdpanther. The vehicle was to feature a 120 mm gun as the main armament. The distinctive feature of the vehicle was three 20 mm MG 151/20 machineguns, mounted on top of the fighting compartment and rear. Existed only in blueprints.

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.

In 1944 the Construction Bureau of the Ural Heavy Machinery Plant developed the SU-101 with the D-10S gun and the SU-102 with the D-25S gun. Both vehicles were designated as Uralmash-1. Prototypes were manufactured in April 1945. The vehicles never entered mass production nor saw service.
