T-80UD ‘Bereza’: Economic Decision


T-80UD on display at a military museum in Russia.

  • Basic Description:
    • The T-80UD, known as Object 478B or Bereza (Birch Tree), is a modified T-80U developed and produced by the Kharkiv Design Bureau of Mechanical Engineering/Malyshev Plant, in the Ukrainian Soviet Socialist Republic, now modern-day Ukraine, that features a 1,000hp 6TD-1 Diesel Engine instead of the GTD-1000TF Gas-turbine Engine. Development began in the early-1980’s followed by mass production in 1985 with an estimated ~600-800 units produced. The T-80UD was adopted due to cost of operating the expensive T-80U and T-80BV main battle tanks. Utilizing the GTD-1000TF, the T-80U and T-80BV can accelerate faster than any other Soviet main battle tank making effectively more maneuverable over the more numerous T-72 and T-64 main battle tanks, however the cost of this maneuverability was high fuel consumption and logistic issues. The T-80U and T-80BV can operate at the very best around ~330km depending on the conditions of the terrain. The solution was to incorporate the 6TD-1 Diesel Engine into the T-80U chassis. The result was an estimated 250km increase in operational range for a total of around 580km at the cost of quick acceleration. This was significant since it made the powerful T-80U cost effective while still retaining its capabilities in firepower and armor protection. This vehicle would be designated the T-80UD. The T-80UD is essentially the same vehicle as the T-80U, featuring the similar electronics, armor, and gun. Some differences can be found in the turret (welded/cast), headlights, exhaust port, Commander’s cupola, and more. The main gun is a 2A46M-1 Smoothbore gun, produced locally in Ukraine as the KBA-3. This gun is fed by a 28rd autoloader which feeds two-part ammunition to the gun breech. The main gun is fired by the gunner, utilizing the 1A42 Fire Control System which includes the 1V528-1 Ballistic Computer, Laser Rangefinder, 1G46/TO1-KO1E Gunner Sight which is night vision capable. The Commander operates the PNK-4S sight capable of night vision. To aid in night time operations, a Luna IR Searchlight is installed next to the main gun. The T-80UD is capable of receiving the TO1-PO2T thermal imager and Shtora-1 countermeasure installed on some T-80U’s, however it is unlikely that Ukrainian T-80UD’s opted for the additional equipment. The fire control components allow the firing of the 9M119 GL-ATGM capable of targeting light vehicles, tanks, and low flying helicopters. Armor protection features the same layout as the T-80U, incorporating 2nd-generation Kontact-5 ERA capable of protecting against HEAT-shaped charges and APFSDS-T alike. Prior to the fall of the Soviet Union, the Soviet Army utilized around ~500-600 of the T-80UD which were intended to become the new standard before passing them on to successor states. Many remained within the newly formed states of the Russian Federation and Ukraine, however the Russian Army is believed to have decommissioned the last T-80UD. Currently Ukraine and Pakistan are the primary operators of the T-80UD with Pakistan operating over 300 units while Ukraine has anywhere from a handful to ~30-50 units in various state of condition. Some were restored to working order relatively recently.

  • In-game :
    • This variant of T-80 features a slower speed versus its gas turbine and lacks the thermal imager upgrade however, the T-80UD can hold its own with its Kontact-5 ERA and powerful 125mm gun. Essentially it’s a T-80U with a slower diesel engine and comes standard with Night Vision that has the capability of being upgraded to a thermal imager.
    • Estimated Battle Rating: 10.3-10.7.

Absolutely belongs in the game! +1

This would be a great addition too the game for the USSR, but I would also love too see the Pakistani T-80UD in the Chinese tree, as it also has a better reverse gear to my understanding

+1 I’d like to see it, but as a folder vehicle or a fork line to introduce the T-84s.

Considering the engines’ differences, the reversing speed of T80UD will be -4km/h I guess

Supposedly the Pakistani version that they bought from Ukraine has the same Transmission as the T-84 so a much better reverse gear

I definitely expect to see Ukrainian modifications to be added soon.

the pakistani one could sit in the chinese tech tree or a squadron. but the third t80 squadron tank would be kinda funny


this vehicle has been in the game however this topic is still open for discussion lmao, it seems that gaijin does not check the forum before adding things to the game
