Object 770

In 1956, the USSR was working on a new type of heavy tank. The Object 770 was an experimental heavy tank project developed in Chelyabinsk Tractor Plant under the leadership of Pavel Isakov.[1][2]

The hull of the Object 770 had a sloped front like the T-54. The tank was manned by a crew of 4. The Object 770 had a NBC protection system. The turret was mounted in the front while the engine is located at the rear.

The Object 770 had a dome-shaped 3 man turret. The turret houses the 130 mm towed field gun M1954 (M-46). The gun had a gun stabilizer and an autoloader. Day and night sighting devices were also installed in the turret. Ammunition consists of 37 rounds. A 1x 14.5mm KVPT machine gun is located in a mount behind the rear of the turret for anti-aircraft defense.

The Object 770 had seven roadwheels and no support rollers. The tank had a hydropneumatic suspension for crew comfort and better accuracy. The tank was powered by a 10-cylinder, four-stroke, DST-10 experimental diesel engine. The engine also had a supercharger. The engine can output 1000 hp and allow the tank to cruise at 55 km/h. [1][2]

In the 1960s, the Soviets embraced the main battle tank (MBT) concept and replaced heavy tanks with mobile medium tanks. All works on the Object 770 was discontinued and only a prototype of the Object 770 was built.[1][2]
