Used T-34/76 D chassis and was designed at the development bureau of General F. F. Petrov. Based on the SU-85 and started to replace it in production in September 1944. The 100 mm gun was a naval gun and it was targeted by a TSch-19 targeting scope. The gun was placed in a ball mounting. A raised cupola was added for the commander. Had external fuel tanks. Sometimes extra ammunition was carried externally on the rear of the tank, however this was quite hazardous. HE shells had an effective range of 20,000 m.

The 100 mm gun fired a 34.5 lb AP shell at a muzzle velocity of 2,950'/sec.⁵
