T-64 was accepted oin service in December, 1966. It has become the first tank of the second generation, The T-64, introduced in the late 1960s, was the first of a sophisticated new family of Soviet main battle tanks developed as successors to the T-54/55/62 family. Retaining the low silhouette of the T-54/55/62 series of tanks, the T-64 featured an innovative design incorporating both an autoloader and advanced armor.
In the early 1950s the tank designers began searching for new ideas, as the Soviet Army needed a radically new tank. As had been so often the case, when radical tank design changes were required, the Tank Design Bureau of Kharkiv led the way by introducing an unconventional if not revolutionary approach to tank design. The new tank design concepts were embodied in the T-64 tank, which was designed in Kharkiv in the early 1960s under the leadership of Aleksandr A. Morozov and became the first vehicle of the new generation of Soviet-designed tanks. The T-64 was the first in the world to feature an automatic loader enabling the crew to be cut from four to three - commander, gunner and driver. Other advanced features included a sophisticated multi-layer protection, NBC protection system, new layout of the power pack compartment, etc.
The T-64 has greater mobility than the T-62. The 5-cyllinder, opposed-piston, diesel engine has an estimated output of 700 to 750 hp. Although the engine is smaller than that of the T-72, the lighter (38 mt) T-64 is believed to have approximately the same road speed and cruising range as the T-72. Two 200-liter auxiliary fuel drums can be fitted on the rear of the hull.
The T-64 has better armor protection than the T-62. The hull and turret are of cast and welded steel armor incorporating both conventional steel armor and ceramic inserts, called Combination K, which provide superior protection against HEAT attack. Besides having greatly increased frontal armor protection due to the use of improved layered armor, the T-64 can also attach track protection plates or full-length skirts. Low- flash fuel storage also offers protection to the sides. The front-mounted shovel enables the tank to dig itself in within a few minutes and also increases the armor protection of the lower hull front when it is folded upwards.
Besides the PAZ radiation detection system and an antiradiation liner, the T-64 also has a collective NBC filtration and overpressure system.
The T-64 has the same integral smoke generating capability as earlier T-54/55/62 tanks, and variants have the same type of turret-mounted smoke grenade projectors as have been observed on the T-72 and T-80.
The main armament comprises a 125mm smooth bore gun which power-elevates from -6? to +14? in a powered turret capable of traversing throughout 360?. The 125-mm smoothbore main gun fires a hypervelocity, armor-piercing, fin-stabilized, discarding-sabot (HVAPFSDS) round believed to have a muzzle velocity of over 1,750 meters per second and an effective range of at least 2,000 meters. The 40-round basic load would typically include 12 HVAPFSDS rounds, 6 HEAT rounds, and 22 HE rounds. The cartridges are semi-combustible with stub-cases. An automatic loader allows the crew to be reduced to three (commander, gunner, and driver), and an automatic spent-cartridge ejection system similar to that of the T-62 is employed.
The 125-mm gun also fires the AT-8 Songster ATGM, and normally carries six AT-8 Songsters plus 36 rounds (projectile and charge) of 125-mm ammunition.
It has an automatic loader, similar to that installed in the T-72, which delivers eight rounds a minute. The incorporation of this innovative automatic loader allowed for a three-man crew.
The commander is capable of operating all weapons in the tank from his position. The T-64 has an improved, integrated fire control system. It probably has an onboard computer, and some variants may have a laser rangefinder.
Since a 1969 was issued improved T-64A from 125-mm smoothb. gun 2A46-1, AD complex new sight.Ammo up to 37 shots have decreased, a mass a little has increased, and the speed has decreased to 60.5 km.
In a 1976 T-64B equipped with a complex of controlled arms «COBRA». It is produced from a trunk of a gun a rocket shell with uncovered in flight wings. A system of its induction - radiocommand, distance of shooting up to 4000 m. T-64B has received a laser sight range finder and new night sight, the combat mass has increased up to 39 tons. The tanks T-64BV are equipped with a system of dynamic guard (POSES). Production O-64 was stopped in a 1987, but the upgraded machines remain in build.
