The T-64BM Bulat is a Ukrainian upgrade of the aging Soviet T-64B main battle tank. Ukraine operates over 2 200 of the old T-64 Main Battle Tanks (MBTs). The Bulat was revealed in 1999. Initially two upgrade variants were proposed - the T-64BM (also referred as the T-64U) and the T-64BM2. The T-64BM2 was fitted with new automatic loader, however it had inferior fire control system. Eventually the more advanced T-64BM upgrade was selected. First vehicles were upgraded and delivered to Ukrainian Army units in 2005. In 2014 this MBT saw action during ongoing military conflict in Ukraine. It was widely used during this conflict. However recently all surviving T-64BM tanks were repaired and put to storage. For some reason Ukrainian military command decided not to use these tanks in conflict and rely on the aging T-64BV tanks.
