Design

Used T-34/76 D chassis and was designed at the development bureau of General F. F. Petrov. The Uralmashzavod took a SU-85 and placed a 100 mm D-10S M1944 naval gun in it.

Crew

The commander had a raised cupola. There was a panoramic periscope in the rotating hatch of the cupola. There were also five episcopes.

The gunner had a rotating periscope in his hatch.

Engine

Had external fuel tanks.

Main Armament

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. The breech block was horizontal sliding and semi-automatic. When the gun is fired, the recoil moves it back to the forward position and the breech is open for the next round. Above the gun are the recuperator and hydraulic buffers.

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.
