Comparing: (R) AMX 50 B vs. Object 777 Version II

Developed starting in 1951 by DEFA, the state weapons design bureau. By 1958, the AMX 50 B received a number of improvements, including a low-profile cast hull and torsion-bar suspension. A new oscillating turret with a 120-mm gun was also mounted on the vehicle. Despite the fact that the Maybach engine power provided just 1000 hp, the specialists from the German Gruppe M company were looking for a solution that would allow the vehicle to reach the speed up to 65 km/h. Only one finished prototype of this variant was built.

The Object 777 is a unique project of a heavy tank. The vehicle was developed at the Chelyabinsk Kirov Plant. By 1953, the design plans were made, and the dummy vehicle was built. The prototype was to feature a cast hull and streamlined turret. The 122-mm M-62-T2 gun was to be mounted on the tank. However, development proceeded no further. The Object 777 never entered mass production nor saw service.
