The T-62 is a Soviet main battle tank that was first introduced 1961. As a further development of the T-55 series, the T-62 retained many design elements of its predecessor including low profile. In contrast previous tanks, which were armed with rifled tank guns, while 100 mm HEAT ammo could have accomplished the task, they were much less accurate than APDS shells, and the relatively low flight velocity resulted in poorer accuracy if used on moving targets. It was decided to up-gun the T-55 with a 115 mm smoothbore cannon, experimental trials showed that the T-55 was inherently unsuited to mount the larger new cannon, and work therefore began on a new tank. The bigger gun required a turret and turret ring to absorb the higher recoil. This in turn necessitated a larger hull, as the T-55 hull was too small to accept the new turret. The T-62 thus took shape, marking an improvement upon the T-55. At the time when Alexander Morozov was working on his Obyekt 430 tank and he was responsible for the T-54A and T-54B modernizations of the T-54 main battle tank, the brainchild of Morozov. After work on the T-54M modernization was abandoned, he and his team started working on a new tank. The new tank had a suspension with six road wheels made of aluminum. The turret was cast and armed with a 100 mm D-54TS tank gun with 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 which reduced the height of the engine compartment, the Obyekt 140 weighed 37.6 tonnes. Morozovs Obyekt 430 tank had a hull of welded rolled steel plates, the turret had three-layer armour with an overall thickness of 185 mm to 240 mm. It was armed with the same D-54TS tank gun as Kartsevs Obyekt 140, in 1957, Uralvagonzavod built two Obyekt 140 prototypes which were put on trials soon after. The trials showed that because of the construction of many of the tanks systems, Kartsevs tank would be expensive in serial production. This increased the load carried by the tank to 45 rounds. At the end of 1958, Kartsev decided to modernize the Obyekt 140 turret and he fitted it with a cartridge-case ejector and mounted it onto a stretched T-55 chassis with a new suspension. He also considered that designs based on already produced vehicles had a chance of acceptance
