Nuclear-Proof Tank, Object 279 (1959):
In the cold war era, Soviet Union built this experimental nuclear explosion proof heavy tank called Object 279 in 1959. It was one of the last Soviet prototypes of heavy tanks before Kruschev banned any tank heavier than 37 tons. Only one unit of Object 279 was built at Kirov Industrial Plant in Leningrad. It weighs 132,277 lbs or 60 metric tons. It had a running gear consisting of four-tracks and a 1000 hp 2DG-8M diesel engine that could power the tank to achieve a speed of 55 kmph with an active range of 300 km per refueling.
The hull of Object 279 had 182-319mm thick armor with CBRN or chemical, biological, radiological and nuclear protection. It was also covered by a thin, elliptical shaped shield protecting it against Armor piercing projectiles and shaped charge ammunition. The elliptical shield also protected it from overturning due to shockwaves of possible nuclear explosions.
