An in-depth illustrated study of the T-64 Battle Tank, the Soviet Union's most secret and controversial Cold War weapon.The T-64 tank was the most revolutionary design of the whole Cold War, designed to provide the firepower and armour protection of a heavy tank in a medium-weight design. It pioneered a host of new technologies including laminate armour, stereoscopic tank rangefinders, opposed-piston engines, smooth-bore tank guns with discarding sabot ammunition, and gun-fired guided projectiles. These impressive features meant that the Russians were loath to part with the secrets of the design, and the T-64 was the only Soviet tank type of the Cold War that was never exported. Written by an armour expert, this detailed technical history sheds light on the secrets behind the Cold War’s most controversial tank, revealing how its highly advanced technologies proved to be both a blessing and a curse.
