T-64BM Bulat Main Battle Tank

💪 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 BM "Bulat"
Started as the Obyekt 447AM-1, this tank presented itself as a modernized version of the T-64BM. After studies of modernization in the early 2000s, work started at the Kharkiv Malyshev Factory design bureau by a first batch of 10 T-64B tanks converted to the BM "Bulat" standard in 2010. These were followed by 19 in 2011 and others in 2012, for a total of 76.

Propulsion:
The T-64BM "Bulat" is 45 tonnes heavy (44 long tons), and keeps its 850 hp (630 kW) 5TDFM multi-fuel diesel engine, which can provide enough torque to allow the Bulat to reach 70 km/h (43 mph) on flat for an operational range of 385 km (239 miles). The 6TD-1 diesel engine (1,000hp) could be also installed in option. The exhaust and air cleaner have are then modernized and adapted. The main engine is two-stroke, five horizontal (flat) cylinder, liquid-cooled, coupled with a gas turbine supercharging. There is, in addition, a planetary gearbox with hydraulic control and frictional switching-on. Performances are the following: Gradient-climbing: 60% slope, 40% side slope, 80 cm vertical step, trench-crossing 2.85 m. it could ford without preparation a 1.8 m deep river, or with preparation up to 5 meters of water.
Armament:
The 125 mm smoothbore gun is fully-stabilized and fed by 28 rounds (36 stored in total) with an autoloader, included 9M119 ATGMs. Practical day range is 2,500 m and 1,500 m at night. Secondary armament comprised the roof KPVT 12.7 mm AA heavy machine gun coupled with a PZU-7 sight, and a coaxial 7.62 mm light machine gun. There is much influence in its modernization coming also from the heavier Ukrainian T-84. The 9M119 Guided missiles have a 90% hit probability (4 000 m) and is controlled by a laser beam.
Electronics:
1A45 Irtysh fire control system (FCS), Buran-E night vision system (detection, identification and targets engagement), TKN-4S tank commander sight. 1G46M sight and TO1-KO1ER night sight/Buran-Catherine thermal imager for the gunner. 2E42M main stabiliser unit, 1V528-1 tank ballistic computer, TAKO-621 guided weapon system, 1ETs29M control system for the anti-aircraft heavy machine guns, PNK-5SR observation and sighting system.
