Design
Used T-34/76 D chassis and was designed at the development bureau of General F. F. Petrov.2 The Uralmashzavod took a SU-85 and placed a 100 mm D-10S M1944 naval gun in it.1
Crew
The commander had a raised cupola.6 There was a panoramic periscope in the rotating hatch of the cupola.6 There were also five episcopes.6
The gunner had a rotating periscope in his hatch.6
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.2 The gun was placed in a ball mounting.2 The breech block was horizontal sliding and semi-automatic.6 When the gun is fired, the recoil moves it back to the forward position and the breech is open for the next round.6 Above the gun are the recuperator and hydraulic buffers.6
