The T-80 is a third-generation main battle tank (MBT) designed and manufactured in the Soviet Union. A development of the T-64, it entered service in 1976. The T-80U was last produced in a factory in Omsk, Russia, while the T-80UD and further-developed T-84 continue to be produced in Ukraine. The T-80 and its variants are in service in Belarus, Cyprus, Egypt, Kazakhstan,Pakistan, Russia, South Korea, and Ukraine. The chief designer of the T-80 was the Russian engineer Nikolay Popov.
The project to build the first Soviet turbine powered tank began in 1949. Its designer was A. Ch. Starostienko, who worked at the Leningrad Kirov Plant (LKZ). The tank was never built because available turbine engines were of very poor quality. In 1955 two prototype 1,000 hp (746 kW) turbine engines were built at the same plant under the guidance of G. A. Ogloblin. Two years later a team led by the famous heavy tank designer Josef Kotin constructed two prototypes of the Ob'yekt 278 tank. Both were hybrids of the IS-7 and the T-10 heavy tanks, powered by the GTD-1 turbine engine, weighing 53.5 tonnes and armed with the M65 130 mm tank gun. The turbine engine allowed the tank to reach a maximum speed of 57.3 km/h (35.6 mph) but with only 1950 liters of fuel on board, range was a mere 300 km (190 mi). The two tanks were considered experimental vehicles and work on them eventually ceased. In 1963, the Morozov Design Bureau designed the T-64 and T-64T tanks. They used a GTD-3TL turbine engine which generated 700 hp (522 kW). The tank was tested until 1965. At the same time at Uralvagonzavod a design team under the guidance of L. N. Kartsev created the Ob'yekt 167T tank. It used the GTD-3T turbine engine which supplied 801 hp (597 kW).
