Object 268, A Soviet Assault Gun.

The Object 268 prototype at the Kubinka tank museum.

In the summer of 1952 development began on Object 268 (Obiekt 268) at the Kirov Plan in Leningrad. The project was overseen by Joseph Kotin. The basis for the project was the T-10 (IS-10) heavy tank. A prototype was produced in 1956 and successfully underwent trials but the vehicle never saw mass production (“Object 268.”). The vehicle featured a 152 mm M-64 main armament; which fired a shell weighing 43.5 kg.  The vehicle possessed a stereoscopic rangefinder on the roof and an experimental V-12-5 engine producing 750 hp (“Obiekt 268 Tank .”).
