History
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]
Description
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 M-65 gun). 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]
Development
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]
