The Object 770 was a prototype Soviet heavy tank that was designed in 1956 by Pavel Isakov at the Chelyabinsk Tractor Plant. It was one of the last heavy tanks ever produced by the Soviet Union and featured many advanced technologies such as hydropneumatic suspension, hydromechanical transmission and a powerful 130mm M-65 cannon.
The Object 770 was developed alongside two other heavy tank projects: the Object 277 and the Object 279. However, all three projects were cancelled in 1960 by Nikita Khrushchev who ordered to stop production of all heavy tanks weighing over 37 tons. Only one prototype of the Object 770 was built and it is currently displayed at the Kubinka Tank Museum.
