Object 780

Developed in the first half of the 1960s, this tank represented a modification of the Object 775 rocket tank prototype. The tank was to have been provided with a 125 mm rifled gun/launching device that could fire both standard shells and rockets. Another unique feature of the tank's design was the placement of the driver in the center of the turret in an immobile cabin that would remain stationary during turret rotation. Existed in blueprints. Some full-size prototypes were manufactured.
