   The T-80U main battle tank is a further development of the T-80. It entered service with the Soviet Army in 1985. Production of T-80 series main battle tanks ceased in Russia in 1992, however its development and production continued in Ukraine. Currently this main battle tank is in service with Russia, China (50), and Cyprus (27). For many years South Korea operated 33 of these main battle tanks, however these were retired in 2019. Due to expensive maintenance Russian Army planned to retire all its T-80 series tanks by 2015. However these tanks are still used. By 2020 a total of 186 T-80 tanks were in active service with the Russian Army.

   The T-80U has a welded hull and cast turret. Armor of this MBT was improved comparing with the previous version. It features composite armor and is fitted with built-in Kontakt-5 Explosive Reactive Armor (ERA) blocks. It is estimated that armor protection of the T-80U is equal to 900 mm against HEAT rounds and 1 100 mm against projectiles. This main battle tank is also fitted with automatic fire suppression and NBC protection systems.

   The T-80U is armed with a fully-stabilized 125 mm smoothbore gun, fitted with an autoloader. It fires armor-piercing, APDS, HEAT and HE-FRAG rounds. Effective range of fire with APFSDS round is 2 000-3 000 m day and 2 000-2 600 at night. Armor penetration is about 590-630 mm at 2 000 m range. The tank can also launch 9M119M Refleks (Western reporting name AT-11 Sniper-B) anti-tank guided missiles in the same manner as ordinary projectiles. These missiles have a maximum range of 5 km and can target low-flying helicopters. The 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.

   Secondary armament consists of 7.62 mm coaxial machine gun and 12.7 mm machine gun, mounted on top of the roof.

   The T-80U MBT was originally produced with a GTD-1000TF gas turbine engine, developing 1 100 hp. Tanks produced in the early 1990s were fitted with a more powerful GTD-1250 gas turbine engine, developing 1 250 hp. It is a multi-fuel engine, which can run on kerosene, diesel, petrol or aviation fuel. It has servicing intervals significantly longer than of diesel engines, however is troublesome to maintain and has very high fuel consumption comparing with diesels. It can consume up to 750 l of fuel for 100 km driven. This engine can be replaced in field conditions within 3 hours. The tank is also equipped with auxiliary power unit, which powers main systems when the tank is stationary.

 

Variants

 

   T-80UK command tank.

   T-80UD is a variant of the T-80U, fitted with more fuel efficient diesel engine instead of the gas turbine. It was adopted in 1986.

   T-80UM-1 Bars developed mainly for export. It is more capable and better protected variant, fitted with improved fire control system and Arena active protection system. It was first publicly revealed in 1997, but never reached production. Only a single prototype was ever built.

   T-80UM-2 is another improved version of the T-80U, aimed mainly at export customers. It was fitted with Drozd-2 active protection system instead of Arena. Only a single prototype was built and it never reached production.

   T-80UE-1 is an upgraded version of the T-80U, fitted with a thermal sight. This version was officially adopted by the Russian Army in 2005.

   T-90 uses complete turret with all weapon systems of the T-80U, mounted on a well proven chassis of the T-72 tank with a diesel engine, which is more fuel efficient. The T-90 was developed after collapse of the Soviet Union and officially adopted by the Russian Army in 1993. Its low-rate production commenced in 1994. Currently the T-90 is the most modern main battle tank, used by the Russian Army. Also it is among the best 10 main battle tanks in the world.

   BREM-80U armored recovery vehicle, specially designed to support the T-80U tanks. There were no production orders for this vehicle.
