The armament of the T-80U-M1 Bars tank is represented by a 125mm 2A46M-4 smoothbore gun/launcher stabilized in both planes. Because of the gun’s increased rigidity, the firing accuracy has been improved by 20 percent, while major assemblies and parts of the dependable 2A46M-1 gun currently in production have been retained.

The tank’s modern fire control system, designated 1A45, includes a laser range finder, a wind sensor, a tank speed indicator, a target speed indicator, a roll angle sensor, ammunition and surrounding medium temperature indicators, and a ballistic computer. In combination with the unique running gear that provides for the smooth running of the vehicle, this system permits the crew to deliver fire effectively while moving cross-country at a speed of 35 km/h with the tank’s turret facing in any direction.

Over the past 10 to 20 years, many countries have been involved in the development of active protection systems for tanks, but only Russia has brought developmental work to fruition and launched production. Arena is one such system. For its performance characteristics there are no other systems in the world that can compare with Arena. This system is designed to protect the tank against antitank grenades and missiles fired by all types of infantry weapons, as well as ground and air-launched ATGMs flying at a speed of 70 to 700 m/s, regardless of the type of control systems and warheads.
