Udarniy

USSRUSSR·Heavy TankHeavy Tank·HT break

In June 1945, the Design Bureau of Factory No. 100 started designing the second tank designated IS-7. Compared to the preliminary variant—the Object 257—armoring and mobility requirements increased. In September 1945, four draft designs were developed for the tank. The Udarniy was a project with enhanced armor, the KCh-30 engine, and an electromechanical transmission.
