T-80 - Production History

Production History

Initially, the T-80 was confused with the Soviet T-72 by some Western analysts, but the T-80 and T-72 are mechanically very different. They are the products of different design bureaus; the T-80 is from the SKB-2 design bureau of the Kirov Factory (LKZ) in Leningrad while the T-72 is from the Uralvagonzavod factory in Nizhny Tagil, Russia. They are similar in superficial appearance, but the T-80 is based on the earlier T-64, while incorporating features from the T-72, which was a complementary design.

The T-64 was the earlier offering of the Morozov Design Bureau (KMDB), a high-technology main battle tank designed to replace the obsolescent IS-3 and T-10 heavy tanks, used in the Red Army's independent tank units. The T-72 was intended to be a tank mass-produced to equip the bulk of the Soviet Motor Rifle units, and for sale to export partners and eastern-bloc satellite states. The mechanically simpler T-72 is easier to manufacture, and easier to service in the field. For many years western analysts denied the usage of gas turbines as main propulsion. From a long distance T-64, T-72 and T-80 look alike even though the T-80 is 90 cm longer than the T-64.

The Leningrad design bureau improved upon the earlier T-64 design, introducing a gas turbine engine in the original model, and incorporating suspension components of the T-72. This gave the tank a high power-to-weight ratio and made it easily the most mobile tank in service, albeit with acute range problems, as the turbine consumed fuel rapidly, even at engine idle. (Morozov's subsequent parallel development of the T-80UD replaced the gas turbine with a commercial turbo-diesel, to decrease fuel consumption and maintenance.) In comparison to its anticipated opponent, the M1 has a larger 1,500 hp (1,120 kW) gas turbine, but weighs 61 tons compared to the T-80s 42.6 tons, so it has a worse hp/t ratio of 24.5 compared to 27.1 and is less maneuverable than the T-80 (with GT). The T-80 can fire the same 9K112 Kobra (AT-8 Songster) anti-tank guided missile through the main gun as the T-64.

The T-80U main battle tank (1985, "U" for uluchsheniye, meaning "improvement") was designed by SKB-2 in Leningrad (hull) and the Morozov Bureau (turret and armament). It is a further development of T-80A and is powered by the 1,250 hp (919 kW) GTD-1250 gas turbine. It is a step ahead of the GTD-1000T and GTD-1000TF engines that were installed on the previous tanks of the T-80 line. This gas turbine can use jet fuels as well as diesel and low-octane gasoline, has good dynamic stability, service life, and reliability. The GTD-1250 has a built-in automatic system of dust deposits removal. It retains the T-80s high fuel consumption, which the Russian army found unacceptable during the Chechen conflicts. It is equipped with the 1A46 fire control system and a new turret. The T-80U is protected by a second generation of explosive reactive armour called Kontakt-5, which can severely dissipate the penetrative capabilities of an APFSDS round, such as the M829A1 "Silver Bullet". The Kontakt-5 is integrated into the design of the turret, hull, and Brod-M deep wading equipment. Like all of the previous T-80 models, the T-80U has full length rubber side skirts protecting the sides but those above the first three road wheels are armored and are provided with lifting handles. It can fire the 9M119 Refleks (AT-11 Sniper) guided missile and the Long-Rod penetrator (HVAPFSDS) 3BM46. The remotely controlled commander's machine gun is replaced by a more flexible pintle-mounted one. A special camouflage paint distorts the tank's appearance in the visible and IR wavebands. The T-80U's 1A46 fire control system includes a laser range finder, a ballistics computer, and a more advanced 1G46 gunner's main sights, as well as thermal imaging sights, which greatly increases the T-80Us firepower over previous models. These new systems, together with the 125mm D-81TM "Rapira-3" smooth bore gun, ensures that the T-80U can accurately hit and destroy targets at a range of up to 5 kilometers (ATGMs and HV/APFSDS).

The T-80U(M) of the 1990s introduced the TO1-PO2 Agava gunner's thermal imaging sight and 9M119M Refleks-M guided missile, and later an improved 2A46M-4 version of the 125 mm gun and 1G46M gunner's sight was used.

Recently, the Russians seem to be abandoning the T-80s design. Perhaps because of the turbine-powered tank's high fuel consumption, and the poor combat performance of older T-80BV tanks in the early days of the war in Chechnya, the Russian Army decided to standardize on the Uralvagonzavod factory's T-90 tank (derived from the T-72BM, but incorporating some T-80 technology), and have had some success selling it to the Indian Army. All T-72s, T-80s, and even the T-90 will be replaced starting 2025 by a new Russian tank which several designs are under development. The Omsk Tank Plant in Siberia is facing a shortage of domestic orders, unlike the Ukrainians which embraced the T-80 design and has had success updating and selling the tank. The Russians have only sold a small number of T-80 tanks to South Korea and China, and have demonstrated versions intended for export, including the T-80UM1 with active protection systems, and the advanced T-80UM2 Black Eagle concept tank. Although the T-80 production has stopped for the Russian Army, the Omsk plant still makes the tank for export. As of 2011 the Russian military has upgraded some T-80s to prolong their service lives, and the T-80 will serve in the Russian army for years to come.
