  • T-64 Main Battle Tank

    The T-64 was said to have been plagued by mechanical problems, leading to a short production life.

    The natural progression of Soviet tank design during the years following World War 2 eventually produced the T-64 Main Battle Tank. The T-64 showcased qualities already having been proven in the war time T-34's successor - the T-54. The T-54 was evolved into the NBC-capable T-55 to which the T-62 was then created as a more advanced option. However, the T-62 failed to surpass the T-54/T-55 series in both combat exposure and sheer production numbers - totaling 22,000 examples to the original's grand estimation of 85,000 to 100,000 units produced. As such the T-55 was remained in production while the T-62 line was discontinued. The T-64, therefore, is what could be considered the Soviet Union's first true "Main Battle Tank" (as the M60 as was to the Americans). Development stemmed from the early 1950s until approximately 1962 to which the type was adopted for service in the Red Army with production beginning in 1963. Production would last until 1987 to which roughly 8,000 to 13,000 examples were delivered. However, the T-64 was never offered up formally for export sales thusly limiting its use to the Red Army. Operators eventually went on to include Moldova, Ukraine and Uzbekistan - mainly due to the fall of the Soviet Empire and stationed Soviet Army tanks being passed on to successor host states. The arrival of the T-64 directly influenced the arrival of the improved American M60A3 production mark in response prior to the development of the failed MBT-70.

    The T-64 was born of a prototype not unlike the T-54/55/62 series before it. There were many notable exceptions in its design to help differentiate it from the former examples. The five large road wheels consistent with earlier Soviet tanks were dropped in favor of six small road wheels to a track side. While the previous designs all lacked track return rollers, the T-64 prototype involved as many as four along the upper track region. The drive sprocket was now relocated to the rear of the hull with the track idler at the front. The hull was suspended by an effective and advanced torsion bar suspension system. The driver's position was now centered at the front hull as opposed to front left. The turret was largely reminiscent of the one featured on the T-62 and original armament was the same 115mm smoothbore main gun (the preceding T-62 design was the first combat tank anywhere in the world to showcase a smoothbore main gun). The T-64's gun was the D-68 (2A21 series) while a pair of snorkels could be erected prior to entering bodies of water for amphibious crossings. The ammunition count totaled 36 x 125mm projectiles and included APFSDS, HEAT-FARG and HE-FRAG types as needed. There was provision at the front hull for the adding of a mine clearing plow. Anti-infantry defense was handled by the 7.62mm PKT coaxial machine gun in the turret. To counter low-flying aerial threats, the crew managed a turret-roof-mounted 12.7mm NSVT series heavy machine gun. Standard NBC protection was afforded to the crew as was a fire extinguishing system. Armor protection ranged up to 450mm in thickness and involved a mix of glass, plastic and steel. Overall weight was roughly 42 short tons. An electro-hydraulic autoloader managed the reloading function of the main gun while reducing the crew to three personnel - the commander, driver and gunner. This not only saved on wait but increased internal volume and allowed for a smaller turret design and, thusly, shallower external profiles. As with the T-62, the T-64 incorporated two-axis stabilization of the main gun. Protection was afforded by the aforementioned composite armor designed to counter the new 105mm guns of Western tanks (explosive reactive armor blocks were eventually added in later T-64 production marks).
