When the T-54M was abandoned, he and his design team started working on a new tank, called Ob'yekt 140. The new tank had a suspension with six light road wheels made of aluminium. The turret was cast and armed with the same D-54TS tank gun and included the Molniya two-plane stabilization system. The tank carried 50 rounds and was powered by a V-36 diesel engine developed by engineer Artiemejev. The engine was placed on the bottom of the hull, a solution that reduced the height of the engine compartment. The Ob'yekt 140 weighed 37.6 tonnes.
