move ended with the 1951 establishment of the KB-60M Design Bureau in Kharkiv. During the post-war period, Morozov turned over further development of the T-54/55 to the Kartsev Design Bureau at Uralvagonzavod, and began work on a next-generation main battle tank, which would become the T-64, for which design Alexander Morozov would receive the Order of Lenin. Factory No. 75, renamed Malyshev Plant in 1957, built tank engines, and later took up production of T-54, T-55 (1958, the most-produced tank ever), and T-64 (1967) tanks. The T-64 was also built in the Leningrad Kirov Plant and Uralvagonzavod Plant. In the 1960s the bureau also designed OT-54 and TO-55 flame-thrower tanks, for production at the Omsk Transport Machine Construction Plant. In 1966, the tank design bureau (Department 60) and experimental tank production shop (Shop 190) were combined into the Kharkiv Machine Building Design Bureau (KMDB). In 1979, after the death of Morozov, it was renamed in his honor. KMDB designed the T-80UD, a diesel-engined variant of the gas turbine-powered T-80, in 1985. Production Military products After the break-up of the Soviet Union, KMDB and the Malyshev factory became the main tank design and manufacture enterprise in Ukraine. However, they were highly dependent on manufacture of components in Russian facilities, especially the Uralvagonzavod factory in Nizhny Tagil. In 1996, Ukraine and Pakistan signed a $650 million contract for delivery of 320 T-80UD tanks. Deliveries were hampered by politically motivated problems with supply of Russian components. Ukraine was forced to develop new manufacturing capabilities and the contract was concluded in 1999. KMDB then began supplying Pakistan with the 6TD-2 diesel engine for installation on the Al-Khalid main battle tank, and has assisted with Pakistan's Al-Zarrar tank project. The T-84 entered service with the Military of Ukraine in 1999, and the more advanced Oplot version in 2001. The tank is actively marketed for export, and can incorporate Russian countermeasure systems and a French fire-control system. The T-84-120 and Yatagan has been developed employing an auto-loaded 120mm tank gun which fires NATO ammunition as well as ATGMs. Versions have seen trials in Greece, Turkey, and Malaysia. KMDB also produces military tractors, trainers and simulators, and upgrade packages for Soviet tanks and APCs. KMDB's BTR-4 armoured personnel carrier has been supplied to Iraq. Armoured personnel carriers BTR-3U - developed in 2000-2001 by a consortium comprising KMDB, State Scientific Technical Centre of Artillery & Rifle Arms (Ukraine)
