T-80
The project to build the first Soviet turbine powered tank began in 1949. Its designer was A. Ch. Starostienko, who worked at the Leningrad Kirov Plant (LKZ). The tank was never built because available turbine engines were of very poor quality. In 1955, two prototype 1,000 hp (746 kW) turbine engines were built at the same plant under the guidance of G. A. Ogloblin. Two years later a team led by Josef Kotin constructed two prototypes of the Object 278 tank. Both were hybrids of the IS-7 and the T-10 heavy tanks, powered by the GTD-1 turbine engine, weighing 53.5 tonnes and armed with an M65 130 mm tank gun. The turbine engine allowed the tank to reach a maximum speed of , however with only 1,950 liters of fuel on board, their range was limited to only . The two tanks were considered experimental vehicles and work on them eventually ceased. In 1963, the Morozov Design Bureau designed the T-64, normally powered by the 5TDF diesel. They also experimented with the T-64T with GTD-3TL turbine engines which generated 700 hp (522 kW). This was tested until 1965. At the same time, at Uralvagonzavod, a design team under the guidance of Leonid N. Kartsev created the Object 167T tank. In 1964, in its report to First Secretary Nikita Khrushchev, the team reported that the design was not worth pursuing partly due to its high fuel use. In 1960, Khrushchev ended all heavy tank programs. LKZ, concerned with the poor reliability of the 5TD diesel engine of the T-64, was freed to focus on gas turbine tank engine development. In 1967, the S. P. Izotov bureau at the Klimov Research-Production Association was assigned to this project. Rather than re-purpose an existing helicopter engine, Izotov built the GTD-1000T from scratch. In 1966, the LKZ built the experimental Object 288 rocket tank, powered by two Klimov GTD-350 turbine engines from the Mil Mi-2 helicopter, offering a combined power of 691 hp (515 kW). Trials indicated that twin propulsion was no better than the turbine engine which had been in development since 1968 at LKZ and Omsktransmash.
The tank from LKZ equipped with this turbine engine was designed by Nikolay Popov. It was constructed in 1969 and designated Object 219 SP1. It was essentially the T-64T powered by a GTD-1000T multi-fuel gas turbine engine producing up to 1,000 hp (746 kW). During the trials it became clear that the increased weight and dynamic characteristics required a complete redesign of the vehicle's suspension. The second prototype, designated Object 219 SP2, received bigger drive sprockets and return rollers. The number of road wheels was increased from five to six. The construction of the turret was altered to use the same compartment, 125 mm 2A46 tank gun, autoloader and placement of ammunition as the T-64A. Some other equipment was borrowed from the T-64A. The LKZ plant built a series of prototypes based on Object 219 SP2. In November 1974, Minister of Defence Andrei Grechko, denied approval to put the Object-219 into production due to the tank's high fuel use and lack of advantages in armament and armour over other tanks then in production. Grechko died in April 1976, and Dmitry Ustinov, an enthusiastic supporter of the Object 219, was appointed in his place. The Object 219-2 was accepted for production as the T-80 in August 1976. The Object 219R, incorporating Combination K composite armour, was accepted for Soviet service in 1978 as the T-80B. Production of the original T-80 ended that same year. The T-80B entered production at Omsktransmash in 1979. Omsk developed a command version called the T-80BK. The T-80B was deployed with the Group of Soviet Forces in Germany in 1981. Initially, the T-80 was confused with the Soviet T-72 by some Western analysts. 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. 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.
Neither the T-80B nor the T-80BV were ever used in the Soviet, Afghan War in the 1980s in order to keep the tank's characteristics a secret, but they were first used during the First Chechen War. This first real combat experience for T-80 was unsuccessful, as the tanks were used to capture cities, a task for which they were not very well suited, in particular due to the low depression and elevation of the 2A46-M1 gun on all Russian MBTs. The biggest tank losses were incurred during the ill-fated assault in the Battle of Grozny, which began in December 1994. During three months of combat, Russia lost 18 of the 84 T-80 tanks used by the 133rd and 3rd Tank Battalions. The forces chosen to capture Grozny were not prepared for such an operation, while the city was defended by, among others, former Soviet soldiers. Some T-80 tanks used in the assault lacked explosive reactive armour inserts. Several tank-to-tank battles were recorded. During the fighting in late December 1994 and early January 1995, Russian T-80 tanks destroyed at least six rebel tanks. On the opposing side, one T-80 was disabled by a 125 mm shell. Another T-80 received three or four tank shell hits but remained in service. In August 1996, a T-80 destroyed one rebel tank. The inexperienced crews had little knowledge of the layout of the city, while the tanks were attacked by rocket-propelled grenade teams hidden in cellars and on top of high buildings. The anti-tank fire was directed at the least armoured parts of the vehicles. In the buildup of forces before the assault on Grozny, T-80s had been transferred from depots to units with little experience with the tank. When no auxiliary power unit is equipped, the T-80's gas turbine engines use almost as much fuel idling as when they are running. Most tank crews inadvertently exhausted their fuel this way on the day of the assault.
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 the 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, diesel, and low-octane gasoline, and has good dynamic stability, service life, and reliability. The GTD-1250 has a built-in automatic system of dust deposit removal. It retains the T-80s high fuel use, which the Russian army found unacceptable during the First Chechen War. It is equipped with the 2A46 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 reduce the penetration of armour-piercing fin-stabilized discarding sabot rounds, such as the M829A1 Silver Bullet, by 38%, and of high-explosive anti-tank rounds. Kontakt-5 had been developed as a response to the threat of modern APFSDS spurred by testing that found that the Israeli 105mm M111 APFSDS ammunition could defeat the glacis armour of the latest models of the T-72 and T-80. 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. Ukrainian T-80UD diesel engine variant continued to be produced in Ukraine. The T80 and its variants are in service in Belarus, Cyprus, Egypt, Kazakhstan, Pakistan, Russia, South Korea, Ukraine and Uzbekistan. Ukraine further developed the T80UD as the T84.
In 1992, the United Kingdom bought a number of T-80U MBTs for defence research and development. They were not bought officially but through a specially created trading company, which was supposed to deliver them to Morocco. The price of $5 million offered for each tank ensured a lack of suspicion on the part of the Russians. The UK evaluated the tanks on its proving grounds and transferred one to the US where the Americans evaluated it at the Aberdeen Proving Ground. In January 1994, British Minister of State for Defence Procurement Jonathan Aitken confirmed in parliamentary debates that a Russian T-80U tank was imported for defence research and development purposes. In 1991, South Korea lent $1.47 billion to the Soviet Union under the agreement to promote economic cooperation between the two nations. Russia originally agreed to repay the loan by 1999, but the Russian government requested a delay due to its own circumstances, which led the expected accumulated sum of principal and interest to near $3 billion. Therefore, South Korea launched Project Brown Bear to collect the debt by purchasing the Russian weapons at a 50% discounted price, with the other 50% covered by the Russian government. As a result, South Korea purchased 33 T-80Us under Brown Bear I, six in 1996 and 27 in 1997, and two T-80Us under Brown Bear II in 2005. Cyprus was the first foreign country to officially obtain T-80 tanks. Russia sold 27 T-80U and 14 T-80UK for $174 million to Cyprus in 1996. The tanks arrived in two batches. The first shipment consisted of 27 T-80U MBTs arriving in 1996, while the second batch of 14 T-80UK MBTs arrived in 1997. This significantly improved the abilities of Cypriot army armoured forces; their most potent tank until then was the AMX-30B2. New tanks gave the Cypriot National Guard the edge in a possible confrontation with the Turkish Army in Northern Cyprus. In October 2009 Cyprus ordered another batch of 41 used T-80Us and T-80UKs from Russia for €115 million. Deliveries were completed in the first half of 2011.
During the Russian invasion of Ukraine, Russian forces used T-80 tanks alongside T-72s and T-90s. Some were outfitted with improvised steel grilles on top of turrets, nicknamed cope cages by Internet users. These were reportedly installed to counter top-attack munitions such as the FGM-148 Javelin and loitering munitions; later into the war the cages were left on and refitted onto more tanks after drone dropped munitions became increasingly prevalent on the battlefield. According to the open source intelligence website Oryx, as of July 2025, at least 1,193 Russian T-80s of multiple variants have been visually confirmed as destroyed, damaged, abandoned, or captured. Of these, 4 are T-80Bs, 690 T-80BV, 4 T-80BVK, 109 T-80BV Obr. 2022, 104 T-80U, 2 T-80UK, 8 T-80UE-1, 1 T-80UM2, 144 T-80BVM, 84 T-80BVM Obr. 2022, and the remaining 43 are unknown variants. Conversely, 81 T-80BVs and 1 T-80UD in service with the Armed forces of Ukraine have been destroyed, damaged, or captured. T-80 tanks were reportedly captured and modified by the Ukrainian military, resulting in the following vehicles: Ukrainian modernized T-80BV: A Ukrainian T-80BV modernization that gives the tank upgrades similar to the T-64BV zr.2017, the official designation of this variant is unknown. Azov Brigade T-80U: Two Russian T-80Us that were captured by Ukraine's Azov Brigade from the Russian 4th Guards Tank Division that underwent modifications to include improved protection. The changes included the installation of Ukrainian Nizh Knife explosive reactive armor. An anti-drone hood, nets under the turret, and a storage rack that also protects the engine deck from drones are all also parts of this modification. The vehicles are used by the 1st Company of the Azov Tank Battalion. They have no official name.
