The modernisation programme, transforming T-64 MBTs to BM Bulat MBTs, focused on improvement of its fire power, mobility and protection. The upgraded sights and aiming devices include a Buran-E night vision system for detection, identification and engagement of targets, and a TKN-4S, the sighting system for the tank commander. The modernisation work included installation of a 1G46M sight and a TO1-KO1ER night sighting system or Buran-Catherine thermal imager for the gunner, some 2E42M main armament stabiliser units, a 1V528-1 tank ballistic computer, a TAKO-621 guided weapon system, a 1ETs29M control system for anti-aircraft machine guns and a PNK-5SR observation and sighting system. The “Bulat” T-64 is the main battle tank of the Ukrainian Armed Forces. It is the result of a rethinking and deep modernization of the Soviet T-64 tank. Over decades of painstaking work, designers were able to bring the fire control, protection, and firepower systems up to the level of modern T-80 and T-84 models. Due to its predecessor, “Bulat” has a recognizable design: side protection side screens, a low-profile turret equipped with passive protection plates, and an ammunition bunker. “Bulat” T-64 is one of the main mechanized combat units in the Ukrainian army. Inheriting the simplicity of the base model, it has significantly improved in characteristics. This combat vehicle can reach speeds of up to 60 km/h on the highway and has a combat range of up to 385 km. The turret turning speed is 40 degrees per second, allowing the tank to quickly respond to threats.
