Teh Obiekt 770ή Αντικείμενο 770, was a prototype heavy tank designed by Pavel Isakov. 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 an 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 KPVT machine gun is located in a mount behind the rear of the turret for anti-aircraft defense. The Object 770 had six 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.

Armament and Protection
- Main Armament: One powerful 130 mm M-65 rifled tank gun (based on a naval gun).
- Autoloader: Features an assisted loading system to handle the heavy ammunition.
- Secondary Armament: One 14.5 mm KPVT heavy machine gun (coaxial).
- Hull Armor: Used a revolutionary one-piece cast hull with extremely sharp angles. Frontal thickness was up to 305 mm, with the severe slope giving exceptional effective thickness.
- Turret Armor: Heavily cast turret with a maximum thickness of 290 mm.
- Protection Concept: The focus was on maximum protection through heavily sloped, thick cast steel, prioritizing survivability over reduced weight.
Powerplant and Mobility
- Engine: V-12 diesel engine (MTD-3) developed by the Kirov Plant.
- Power Output: 1,000 hp.
- Maximum Road Speed: Approx. 55 km/h (34 mph).
- Suspension: Advanced **hydrodynamic individual suspension** on all road wheels, allowing the tank to “kneel” for hull-down firing positions.
- Cancellation Reason: Despite its advanced protection and innovative suspension, the tank was deemed too complex and expensive for mass production, especially as Soviet military doctrine shifted away from dedicated heavy tanks in favor of Main Battle Tanks (MBTs).
