   The T-80BVM is an upgraded version of the T-80BV main battle tank. It was first publicly revealed in 2017. Currently Russia operates a total of 4 500 T-80 main battle tanks of all variants. Due to high operational costs these tanks are being kept in reserve. Currently the main operational tanks of the Russian Army are the T-90 and overhauled or upgraded versions of the T-72. The main reason is that these tanks with conventional diesel engines are less expensive to operate and to maintain than the T-80s. Earlier it was planned that all Russian T-80 series tanks will be retired by 2015. However in 2017 Russian MoD signed a contract to refurbish and upgrade a total of 62 T-80BV tanks to the T-80BVM standard in order to keep them in operational service. In 2018 a first batch of 31 T-80BV tanks was upgraded to the T-80BVM standard. These operational tanks were first publicly revealed during a military parade in 2018. However these initial tanks lacked some features of the T-80BVM demonstrator, that was revealed in 2017. Upgrade of the T-80BV tanks to the T-80BVM standard continued in 2019 when another 31 tanks were delivered. In 2020 a contract was signed to upgrade another 50+ T-80BV tanks to the new standard.

   The upgraded T-80BVM has slightly improved armor protection. It is fitted with Relikt explosive reactive armor kit. The same armor is used by the latest Russian main battle tanks, such as T-90M and T-90MS. However the T-80BVM was the first operational tank to be fitted with this new explosive reactive armor. The Relikt provides protection against tandem warheads and reduces penetration of APFSDS rounds by over 50%. The tank is fitted with rubber side skirts, with built-in armor plates. Rear parts of the hull and turret are covered by cage armor. The T-80BVM is reportedly fitted with a passive countermeasures system, which improved protection against some types of anti-tank guided missiles.

   The T-80BVM retains a 125 mm smoothbore gun. However it uses a newly-built 2A46M-4 gun, which has longer range and is 15-20% more accurate than the 2A46M-1 gun of the T-80BV. Effective range of fire with APFSDS round is 2 000-3 000 m day and 2 000-2 600 m at night. Armor penetration is around 590-630 mm at 2 000 m range. The T-80BVM is compatible with newly developed Svinets-1 and Svinets-2 APFSDS rounds with tungsten and depleted uranium penetrators.

   The tank can also launch 9M119M Refleks (Western reporting name AT-11 or Sniper-B) anti-tank guided missiles in the same manner as ordinary munitions. These missiles extend the effective range of the 125 mm gun, which lacks accuracy at longer ranges. These missile have a range of 4-5 km and can also engage low-flying helicopters. Missiles use a semi-automatic laser guidance and have a claimed hit probability of 80% at 4 000 m range and 70% at 5 000 m range. Maximum rate of fire is 6-8 rounds per minute. However judging by recent tank biathlons in Russia it turned out that these guided missiles have a hit probability against stationary targets of only around 50%. These missiles will be even less accurate against moving targets.

   The T-80BVM carries 45 rounds and missiles for the main gun. The gun is loaded automatically by the autoloader. If the autoloader fails, the gun can be loaded manually.

   Secondary armament consists of a coaxial 7.62 mm machine gun and roof-mounted 12.7 mm machine gun.

   Fire control system has also been upgraded.

   The T-80BVM has a crew of three, including commander, gunner and driver.

   The T-80BVM retains its GTD-1250TF gas turbine engine, developing 1 250 hp. Basically it is a helicopter powerplant, modified for use on tanks. Advantages of such engine are its compact dimensions, high power output and ability to start when the temperature is as low as -40C. Due to this feature the T-80 series tanks can be used in Northern areas of Russia. Also the T-80 series tanks are much faster than the T-64, T-72 and T-90 series tanks with diesel engines, and have superior cross-country performance. However its gas turbine engine has a number of drawbacks. Most notable is a high fuel consumption. It can consume up to 750 liters of fuel for 100 km driven. Other drawbacks are troublesome maintenance and high unit price. The T-80BVM is also fitted with auxiliary power unit, powering all systems, when the main engine is turned off.
