== History ==
=== Development ===
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&nbsp;hp (746&nbsp;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 Tank|T-10]] heavy tanks, powered by the GTD-1 turbine engine, weighing 53.5 tonnes and armed with an M65 130&nbsp;mm tank gun. The turbine engine allowed the tank to reach a maximum speed of {{convert|57.3|km/h|mph|abbr=on}}, however with only 1,950 liters of fuel on board, their range was limited to only {{convert|300|km|mi|abbr=on}}. The two tanks were considered experimental vehicles and work on them eventually ceased.

In 1963, the [[Kharkiv Morozov Machine Building Design Bureau|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&nbsp;hp (522&nbsp;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 [[General Secretary of the Communist Party of the Soviet Union|First Secretary]] [[Nikita Khrushchev]], the team reported that the design was not worth pursuing partly due to its high fuel use.{{sfn|Kolekcja Czołgi Świata|pp=1–2}}{{sfn|Sewell|1998}}

[[File:T-80 during maneuvers.JPEG|thumb|left|Soviet T-80 during manoeuvres, March 1986.]]
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|Klimov Research-Production Association]] was assigned to this project. Rather than re-purpose an existing helicopter engine, Izotov built the GTD-1000T from scratch.{{sfn|Zaloga|2009|pp=8–10}}

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&nbsp;hp (515&nbsp;kW). Trials indicated that twin propulsion was no better than the turbine engine which had been in development since 1968 at LKZ and [[Omsktransmash]].{{sfn|Kolekcja Czołgi Świata|p=2}}

==== Object 219 ====
The tank from LKZ equipped with this turbine engine was designed by [[Nikolay Popov]]. It was constructed in 1969 and designated ''Object 219 SP1''.{{sfn|Zaloga|2009|p=10}} It was essentially the T-64T powered by a GTD-1000T [[multi-fuel]] gas turbine engine producing up to 1,000&nbsp;hp (746&nbsp;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&nbsp;mm [[2A46 125 mm gun|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.{{sfn|Kolekcja Czołgi Świata|p=2}}

==Production history==
[[File:Russian T-80BV.jpg|thumb|left|This T-80BV has reactive armour adapted to its turret and hull. The later T-80U has a large [[Vehicle armour#Appliqué|appliqué]] of [[explosive reactive armour]] installed — providing higher crew and tank survivability than prior models.]]
In November 1974, [[Minister of Defence (Soviet Union)|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.{{sfn|Zaloga|2009|pp=10–11}}{{sfn|Sewell|1998|pp=21–29, 45}}

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.{{sfn|Zaloga|2009|pp=13–14}}

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.{{sfn|Sewell|1998|pp=28–29}} The T-64 in turn was an earlier high-technology main battle tank, designed by the Morozov Design Bureau in [[Kharkiv]] to replace the T-54/55 and T-62 MBTs, used before in the [[Soviet Union]].

From a distance, the [[T-64]], T-72 and T-80 look alike. Despite the similarities, the T-80 is 90&nbsp;cm longer than the T-64, and the T-80 and T-72 are mechanically very different. The T-72 is mechanically simpler, easier to manufacture, and easier to service in the field. As such, 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 T-80 design improved on several aspects of the earlier T-64 design, introducing a gas turbine engine in the original model,{{efn|Denied for many years by Western analysts.{{sfn|Kolekcja Czołgi Świata|p={{page needed|date=September 2010}}}}}} 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 used 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 use and maintenance needs.) In comparison to its anticipated opponent, the American [[M1 Abrams]] 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).{{Citation needed|date=April 2025}} The T-80 can fire the same [[9K112 Kobra]] (AT-8 Songster) [[anti-tank guided missile]] through the main gun as the T-64.

[[File:4thTankBrigade - T-80U -01.jpg|thumb|left|Russian T-80U of the 4th Tank Brigade, 2011]]

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.{{Citation needed|date=April 2025}} The GTD-1250 has a built-in automatic system of dust deposit removal. It retains the T-80s high fuel use, which the [[Russian Ground Forces|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]] (APFSDS) rounds, such as the [[M829 (munition)#M829A1|M829A1 "Silver Bullet"]], by 38%, and of [[high-explosive anti-tank]] (HEAT) rounds.<ref>{{cite web |url=http://fofanov.armor.kiev.ua/Tanks/EQP/era.html |title=Modern Explosive Reactive Armours |publisher=Fofanov.armor.kiev.ua |access-date=22 September 2013 |archive-url=https://web.archive.org/web/20130927155159/http://fofanov.armor.kiev.ua/Tanks/EQP/era.html |archive-date=27 September 2013 |url-status=live}}</ref> ''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.{{sfn|Zaloga|2009|p=23}}

[[File:T-80U tank interior -01.jpg|thumb|T-80U gunner position]]
[[File:T-80U tank interior -04.jpg|thumb|T-80U commander position]]
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 with those above the first three road wheels being armoured and are provided with lifting handles. It can fire the [[9M119 Refleks]] (AT-11 Sniper) guided missile and the long-rod penetrator (HVAPFSDS) 3BM46.{{Citation needed|date=April 2025}} The remotely controlled commander's machine gun was replaced by a more flexible pintle-mounted one. A special camouflage paint distorts the tank's appearance in the visible and IR wavebands.{{Citation needed|date=April 2025}} 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, which greatly increases the T-80Us firepower over previous models. These new systems, together with the 125 mm D-81TM "Rapira-3" smooth bore gun, ensure that the T-80U can hit targets at a range of up to 5 kilometers (ATGMs and HV/APFSDS).{{Citation needed|date=April 2025}} An experienced crew at the international exhibition was able to successfully strike 52 targets without a miss at a distance of 5 km using guided rockets.<ref>{{cite web |url=http://www.sinopa.ee/sor/boraznoe/t90/t9002.htm |title=ČŃĻŪŅĄĶČß ŅĄĶŹĄ Ņ-90 |website=www.sinopa.ee |access-date=5 December 2014 |archive-url=https://web.archive.org/web/20150924102058/http://www.sinopa.ee/sor/boraznoe/t90/t9002.htm |archive-date=24 September 2015 |url-status=live}}</ref>{{Unreliable source?|date=April 2025|reason=Article is pure Russian propaganda. It makes completely unsubstantiated claims of tanks taking 6 tank rounds point blank and still driving away, while blaming any and all recorded failures "during the American-Iraqi conflict and during the military conflicts in the Transcaucasus" on "improper use of tanks in the troops - an insufficient level of support for their combat use, and in some cases, incorrect tactics for using tanks... overwhelming majority of failures and malfunctions occur due to insufficient knowledge of the material part and a weak level of technical maintenance."}}

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.

Russian tank production faltered in the years before and after the breakup of the Soviet Union. At the two remaining Russian tank plants, state orders all but ceased. Omsk, then the only Russian producer of the T-80, received orders for just five T-80Us in 1992. Around the same time, the Russian Ministry of Defense decided it would commit to eventually producing one tank type only. Though both Nizhni-Tagil's [[T-90]] and Omsk's T-80U had their merits, the T-80 was notorious for its high fuel use and production cost. Also, Russian T-80BVs suffered appalling losses in their first combat use during the First Chechen War. T-90s, which were not deployed to Chechnya, were spared media criticism despite the similarly poor performance of the T-72 (the T-90's not-so-different ancestor) in the same conflict. In January 1996, Colonel General [[Aleksandr Galkin (general)|Aleksandr Galkin]], chief of Main Armour Directorate of the Russian Ministry of Defense, said the Russian Armed Forces would phase out T-80 production in favor of the T-90 (Galkin reversed his position later that year, claiming the T-80U was a superior tank). Production of the T-80 at Omsk persisted until 2001, mainly for the export market.<ref name="Zaloga90">{{cite book |last1=Zaloga |first1=Steven J. |title=T-90 Standard Tank |date=2018 |publisher=Osprey Publishing |isbn=978-1-4728-1822-5 |pages=16–17 |chapter=The Chechen War}}</ref> In September 2023, the CEO of [[Uralvagonzavod]], [[Alexander Potapov (business executive)|Alexander Potapov]], said that they had been tasked by the military to resume manufacture of the T-80.

In parallel with the T-80U and Russia in general, the Morozov Bureau in [[Ukraine]] developed a diesel-powered version, the T-80UD. It is powered by the 1,000&nbsp;hp 6TD-6-cylinder opposed-piston<ref>{{cite report |title=Prospects Of Application Of Two-Stroke Turbo-Piston Opposed-Piston Diesel Engine Of TD Family In Armored Vehicles |publisher=Kharkov Engine Design Bureau |url=http://trosol-defence.com/wp-content/uploads/2017/02/6TD-engines-presentation.pdf |url-status=usurped |archive-url=https://web.archive.org/web/20200808005618/http://trosol-defence.com/wp-content/uploads/2017/02/6TD-engines-presentation.pdf |archive-date=8 August 2020}}</ref> multi-fuel two-stroke turbo-piston diesel engine, ensuring high fuel efficiency and a long cruising range. The engine support systems make it possible to operate the tank at ambient temperatures of up to 55&nbsp;°C and ford water obstacles 1.8&nbsp;m in depth. The T-80UD shares most of the T-80U's improvements, but can be distinguished from it by a different engine deck and distinctive smoke-mortar array and turret stowage boxes. It retains the remotely-controlled commander's machine gun. About 500 T-80UD tanks were built in the [[Malyshev plant]] between 1987 and 1991. About 300 were still at the Ukrainian factory when the Soviet Union broke up, so the T-80UD tank was welcomed into Ukrainian military service, and therefore is more common in Ukrainian service than Russian. Unlike Russia, Ukraine has had much better success selling T-80s to foreign customers. [[Cyprus]] bought a number of T-80Us and T-80UKs from Russia for its army. [[Pakistan]] bought Ukrainian T-80UDs for the [[Pakistan Armoured Corps]].{{sfn|Zaloga|2009|pp=38–39}}

The Ukrainian [[T-84]] main battle tank is based on the T-80UD. Ukraine was only able to afford a negligible number of T-84s for its own use, but did market the tank for export. The T-84 Oplot (first delivered in 2001) introduced turret-bustle ammunition storage; and to offer more sales to international market, the T-84-120 Yatagan has been offered for export, featuring a very large turret bustle and NATO-compatible 120&nbsp;mm gun.{{sfn|Zaloga|2009|pp=28–43}}

===Soviet Union===
[[File:1991 coup attempt4.jpg|thumb|right|Two T-80UDs on the [[Red Square]] in [[Moscow]] during the failed August [[1991 Soviet coup d'état attempt]]]]
In 1989, there were 3,000 T-80 MBTs overall.<ref>{{cite book |last1=Institute for Strategic Studies |title=The military balance, 1989–1990 |date=1989 |publisher=Brassey's |location=London |isbn=978-0080375694 |page=34 |author1-link=Institute for Strategic Studies }}</ref> According to data published in Russia, 2,256 T-80s (up to the T-80BV model, as T-80Us were never deployed in Europe) were stationed with the Group of Soviet Forces in Germany in [[East Germany]] between 1986 and 1987. In 1991, when the Soviet Union was breaking up, the Soviet Army operated 4,839 T-80 MBTs of several different models.{{sfn|Kolekcja Czołgi Świata|p=10}}

In August 1991, communists and allied military commanders tried to overthrow [[Mikhail Gorbachev]] and regain control over the unstable Soviet Union. T-80UD tanks of the [[4th Guards Kantemirovskaya Tank Division]] drove onto the streets of [[Moscow]], but the [[1991 Soviet coup d'état attempt|Soviet coup attempt]] failed when the tank crews refused to attack the crowd or the parliament.{{sfn|Kolekcja Czołgi Świata|p=11}}{{sfn|Zaloga|2009|p=27}}

===Russia===
[[File:Холодноярівська піхота знищила російський танк Т-80 01.jpg|thumb|Russian T-80U tank destroyed by [[Next generation Light Anti-tank Weapon|NLAW]] during the 2022 Russian invasion of Ukraine]]
Before the [[2022 Russian invasion of Ukraine]], the T-80 was not used in the way in which it was intended (large-scale conventional war in [[Europe]]). Until 2022, it was deployed amid the political and economic turmoil in Russia during the 1990s.

Most T-80 MBTs are possessed by Russia, though many were inherited by Ukraine, Belarus and Kazakhstan.

In 1995, the number of T-80 tanks increased to around 5,000 but shrank to 3,500 in 1998.

The Russian Army had 3,044 T-80s and variants in active service and 1,456 in reserve {{As of|2008|lc=y}}.{{sfn|Kolekcja Czołgi Świata|p=10}}<ref name="Warfare.ru">{{cite web |url=http://warfare.be/?linkid=1776&catid=244|title=warfare.be|website=warfare.be}}</ref> There are at least 460 T-80U in service with the 2nd Guards Tamanskaya Motor Rifle Division and 4th Guards Kantemirowsk Motor Rifle Division.{{sfn|Kolekcja Czołgi Świata|pp=11–12}} A T-80BV is on display in [[Kubinka Tank Museum]] and a T-80U is on display at an open-air museum in [[Saratov]]. The T-80Us have recently been seen at arms expos in Russia such as VTTV.

During the [[1993 Russian constitutional crisis]], [[Boris Yeltsin]] ordered the use of tanks against the [[Supreme Soviet of Russia|Supreme Soviet]] and the [[Congress of People's Deputies of Russia|Congress of People's Deputies]] opposing him. On 4 October 1993, six T-80UDs from the 13th Guards Tank Regiment, 4th Guards Kantemirovskaya Tank Division took positions on a bridge opposite the [[White House, Moscow|Russian parliament building]], and fired on it.

====First Chechen War====
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 (1994–1995)|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.<ref>{{citation |first=В. |last=Белогруд |title=Yandex |script-title=ru:Танки в боях за Грозный |trans-title=Tanks in the battle of Grozny |volume=2 |url=https://yadi.sk/i/gPlkrCoW3Q2rQw |year=2008 |pages=48–50 |language=ru}}</ref> 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.{{sfn|Zaloga|2009|pp=31–32}}

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&nbsp;mm shell.<ref name="ReferenceB">В. Белогруд. Танки в боях за Грозный. Часть 1.

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.<ref name="Grau">{{cite web |last=Grau |first=Lester W. |url=http://fmso.leavenworth.army.mil/Red-Star/issues/JAN97/JAN97.HTML#RUSSIAN |title=Russian-Manufactured Armored Vehicle Vulnerability in Urban Combat: The Chechnya Experience |work=Red Thrust Star |publisher=US Army |date=January 1997 |url-status=dead |archive-url=https://web.archive.org/web/20090709131323/http://fmso.leavenworth.army.mil/Red-Star/issues/JAN97/JAN97.HTML#RUSSIAN |archive-date=9 July 2009}}</ref>

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.{{sfn|Zaloga|2009|pp=31–32}}{{sfn|Sewell|1998|pp=21–29, 45}}

====After the First Chechen War====
The T-80 performed so poorly in the First Chechen War that after the conflict, General-Lieutenant Aleksandr Galkin, head of the Armour Directorate, convinced the Minister of Defence to never again procure tanks with gas turbine engines<ref>Mikhail Zakharchuk, 'Uroki Chechenskogo krizisa' (Lessons of the Chechen crisis), Armeyskiy sbornik, April 1995, 46.</ref> (Galkin reversed his position in 1996, claiming that the T-80U was superior to the T-90).<ref name="Zaloga90"/> After that, T-80 MBTs were never again used to capture cities, and instead, supported infantry squads from a safe distance. Defenders of the T-80 explain that the T-72 performed just as badly in urban fighting in Grozny as the T-80 and that there were two aggravating factors: after the breakup of the Soviet Union, poor funding meant no training for new Russian tank crews, and the tank force entering the city had no infantry support.{{sfn|Kolekcja Czołgi Świata|pp=11–12}}

Russia did not deploy T-80 tanks in later conflicts such as the 1999 [[Second Chechen War]], the 2008 [[Russo-Georgian War]],<ref>{{cite web |url=https://warisboring.com/the-t-80-is-russia-s-most-overrated-tank-798b5ba54ff9 |first=S.K. |last=Au-yeong |title=The T-80 Is Russia's Most Overrated Tank |archive-url=http://webarchive.loc.gov/all/20160907043706/https://warisboring.com/the-t-80-is-russia-s-most-overrated-tank-798b5ba54ff9 |archive-date=7 September 2016 |website=War is boring |date=10 August 2015}}</ref> or the post-2014 [[Russo-Ukrainian War]]<ref>{{cite web |title=T-80 |website=The Online Tank Museum |url=http://tanks-encyclopedia.com/coldwar/ussr/t-80.php |access-date=18 August 2016}}</ref> until the full scale invasion in 2022.

====Russian invasion of Ukraine====
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.<ref>{{cite news |date=12 March 2022 |title=What to know about the role Javelin antitank missiles could play in Ukraine's fight against Russia |url=https://www.washingtonpost.com/world/2022/03/12/javelins-ukraine-russia/ |newspaper=[[Washington Post]] |quote=Social media has been littered with photos of destroyed Russian tanks with cages.

According to the open source intelligence website [[Oryx (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.<ref>{{Cite web |last=Oryx |title=Attack On Europe: Documenting Russian Equipment Losses During The Russian Invasion Of Ukraine |url=https://www.oryxspioenkop.com/2022/02/attack-on-europe-documenting-equipment.html |access-date=17 December 2024 |website=Oryx}}</ref>

T-80 tanks were reportedly captured and modified by the Ukrainian military, resulting in the following vehicles:

*'''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.<ref>{{Cite web |title=Exclusive: Azov Details Upgrades to Russian-Captured T-80U Tanks |url=https://militarnyi.com/en/news/exclusive-azov-details-upgrades-to-russian-captured-t-80u-tanks/ |access-date=4 April 2025 |website=Militarnyi |language=en-US}}</ref>

===Exports===
====United Kingdom====
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 [[USD|$5]] million offered for each tank ensured a lack of suspicion on the part of the Russians.{{why|date=August 2024}} 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".{{sfn|Kolekcja Czołgi Świata|p=12}}<ref name="House of Commons">[https://publications.parliament.uk/pa/cm199394/cmhansrd/1994-02-03/Writtens-9.html Hansard Debates for 3 Feb 1994] {{Webarchive|url=https://web.archive.org/web/20170910083755/https://publications.parliament.uk/pa/cm199394/cmhansrd/1994-02-03/Writtens-9.html |date=10 September 2017}} UK House of Commons</ref>

====South Korea====
[[File:T-80U ROKA 제3기갑여단.jpg|thumb|Republic of Korea Army T-80U]]
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.<ref>{{Cite web |date=6 October 2022 |title=러시아, 경협차관 약 433억 미상환 |url=http://www.dhns.co.kr/news/articleView.html?idxno=292773 |access-date=1 December 2024 |website=대한뉴스 |language=ko}}</ref>

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. Although some domestic media claimed the acquisition of two T-80UKs instead of T-80Us, South Korean officials never confirmed this. They also denied Russian media claims of buying 140 T-80U and T-80UKs, calling it false information to promote a Russian defense exhibition.{{sfn|Kolekcja Czołgi Świata|p=13}}<ref name="f077">{{cite web | last=Carlin | first=Maya | title=Why Seoul Still Possesses Soviet T-80 Tanks | website=The National Interest | date=10 May 2025 | url=https://nationalinterest.org/blog/buzz/why-seoul-still-possesses-soviet-t-80-tanks | access-date=13 June 2025}}</ref><ref name="m370">{{cite web | title="러시아産 전차 구입 기사는 誤報" | website=네이버 뉴스 | date=21 August 2023 | url=https://n.news.naver.com/mnews/article/001/0001023241?sid=104 | language=ko | access-date=26 June 2025}}</ref>

When South Korea first acquired the T-80 in the late 1990s, it was the most powerful tank on the Korean Peninsula, superior to the domestic [[K1 88-Tank]] in having a larger 125&nbsp;mm gun to the K1's 105&nbsp;mm. However, as time went on, the K1 was upgraded into the K1A1 and the more advanced [[K2 Black Panther]] entered service, while the T-80 changed little since its delivery due to the foreign nature of the design and lack of will to add domestic upgrades. While the South Korean tanks use domestically manufactured ammunition, T-80 shells and most parts must be imported, increasing maintenance costs as the cost of ordering replacement parts kept rising steadily. Although the turbine engine is lighter with better acceleration, it uses more fuel and is less reliable. The interior has been criticized as cramped and gunnery was underperforming via less advanced sights and slower reload speed.<ref>[http://nationalinterest.org/blog/the-buzz/why-south-korea-hates-loves-its-russian-tanks-25373 Why South Korea Hates (and Loves) Its Russian Tanks] {{Webarchive|url=https://web.archive.org/web/20180416232721/http://nationalinterest.org/blog/the-buzz/why-south-korea-hates-loves-its-russian-tanks-25373 |date=16 April 2018}}.

====Pakistan====
Ukrainian exports of the T-80UD have been moderately successful. In 1993 and 1995, Ukraine demonstrated the tank to Pakistan, which was looking for a new main battle tank. The tank was tested in Pakistan and in August 1996 Pakistan decided to buy 320 T-80UD tanks from Ukraine for $650 million in two variants: a standard Object 478B and export Object 478BE.{{sfn|Kolekcja Czołgi Świata|p=13}}<ref name="T-80UD deagel">{{cite web |title=T-80UD |url=http://www.deagel.com/Main-Battle-Tanks/T-80UD_a000370002.aspx |website=Deagel |access-date=20 August 2008 |url-status=live |archive-date=3 March 2016 |archive-url=https://web.archive.org/web/20160303172257/http://www.deagel.com/Main-Battle-Tanks/T-80UD_a000370002.aspx}}</ref><ref name="NTW 07/09">{{cite magazine |title=Nowa Technika Wojskowa |magazine=New Military Technique |issue=7/09 |language=pl |issn=1230-1655}}{{full citation needed|date=April 2022}}</ref> The tanks were all supposed to be delivered in 1997.

====Cyprus====
[[File:The Wall of Death.jpg|thumb|[[Cypriot National Guard|Cyprus National Guard]] T-80 main battle tanks during the 1 October parade in [[Nicosia]].]]
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-30]]B2.

====Failed export attempts====
Apart from Cyprus and the People's Republic of China,{{sfn|Kolekcja Czołgi Świata|p=13}} Russia has tried to export T-80 MBTs to Turkey and Greece, who were looking for new tanks. These two attempts have failed.{{sfn|Kolekcja Czołgi Świata|p=13}} Sweden regarded the T-80U as an alternative for its mechanized brigades in the early 1990s if the [[Leclerc tank|Leclerc]] would have been chosen for armoured brigades,<ref>{{Cite web |title=När fienden kom till Sverige |url=https://www.ointres.se/ryska_strf_till_sverige.htm |access-date=21 April 2023 |website=www.ointres.se}}</ref> but since the new upgraded Leopard 2 ([[Stridsvagn 122|Strv 122]]) was chosen, Leopard 2A4s ([[Leopard 2|Strv 121]]) equipped the mechanized brigades as to simplify logistics.

==Description==
The T-80 is similar in layout to the T-64; the driver's compartment is on the centre line at the front, the two-man turret is in the centre with the gunner on the left and the commander on the right, and the engine is rear mounted.{{sfn|Foss|2005|p=89-90}} Overall, its shape is also very similar to the T-64.

=== Mobility ===
[[File:WMDTankExercise2018-05.jpg|thumb|right|T-80U underwater driving exercise, [[4th Guards Tank Division]] in 2018]]
The original T-80 design uses a 1,000&nbsp;[[Horsepower|hp]] [[monobloc engine|monobloc]] gas turbine engine instead of a 750-hp diesel engine of the T-64;{{sfn|Zaloga|2009|p=10}} later variants of the T-80 reverted to diesel engine usage. The gearbox is different, with five forward and one reverse gear, instead of seven forward and one reverse. Suspension reverts from pneumatic to torsion bar, with six forged steel-aluminium rubber-tyred road wheels on each side, with the tracks driven by rear sprockets.{{sfn|Foss|2005|pp=89–90}} Later models such as the T-80U were equipped with 1250hp turbines. {{sfn|Zaloga|2009|p=24}}

The tracks are slightly wider and longer than on the T-64 giving lower ground pressure.{{sfn|Foss|2005|pp=89–90}}

=== Armament ===
The turret houses the same 125&nbsp;mm [[2A46]] smoothbore gun as the T-72, which can fire regular ordnance and anti-tank guided missiles.{{sfn|Foss|2005|p=89-90}}

The main gun is fed by the ''Korzina'' automatic loader. This holds up to 28 rounds of two-part ammunition in a carousel located under the turret floor.{{sfn|Warford|1995}} Further ammunition is stored in the turret. The ammunition comprises the projectile (APFSDS, HEAT, or HE-Frag), and the propellant charge, or the two-part missile.{{sfn|Warford|1995}} The autoloader is an effective, reliable, combat tested system that has been in use since the mid-1960s. The propellant charge is held inside a semi-combustible cartridge case made of a highly flammable material, which is consumed in the breech during firing, except for a small metal baseplate.{{sfn|Warford|1995}}

[[File:Engineering Technologies - 2012 (1-08).jpg|thumb|right|T-80U firing gun in 2012]]
The autoloader takes between 7.1 and 19.5 seconds to load the main weapon (28 rounds<ref name="all-tanks.ru">{{cite web |title=Основной танк Т-80 |language=ru |trans-title=Main Tank T-80 |url=http://all-tanks.ru/content/osnovnoi-tank-t-80 |access-date=6 December 2014 |url-status=dead |archive-date=13 December 2014 |archive-url=https://web.archive.org/web/20141213015852/http://all-tanks.ru/content/osnovnoi-tank-t-80}}</ref>), depending on the initial position of autoloader carousel.{{clarify|date=April 2022|reason=Why or how does 28 rounds effect time to load one round?}}{{citation needed|date=April 2022|reason=I did not find either time in the source.}}

=== Armour ===
The [[glacis]] is of laminate armour and the turret is armoured steel, with cavities in the turret cheeks containing either a ceramic filling or [[Reactive armour|non-explosive reactive armour]] elements.{{sfn|Foss|2005|p=89-90}}

The T-80's armour is composite on the turret and hull, while rubber flaps and sideskirts protect the sides and lower hull. Later T-80 models use [[explosive reactive armour]] ([[Kontakt-1]], [[Kontakt-5]] or Relikt<ref>{{Cite web |title=T-80 Tank {{!}} Full details of entire series history & models |url=https://fighting-vehicles.com/tanks/t-80-tank/ |access-date=5 September 2024 |website=FightingVehicles.com |language=en-US |archive-date=23 September 2024  |archive-url=https://web.archive.org/web/20240923184231/https://fighting-vehicles.com/tanks/t-80-tank/ |url-status=dead }}</ref>) and stronger armour, like the T-80U and T-80UM1. Other protection systems include the [[Shtora-1]] and [[Arena (countermeasure)|Arena APS]], and the discontinued [[Drozd]] APS.{{citation needed|date=July 2024}}

A disadvantage highlighted during combat in [[Chechnya]] was the vulnerability of the T-80BV to [[Catastrophic kill|catastrophic explosion]]{{sfn|Warford|1995}} thought to be caused by the vulnerability of stored semi-combustible propellant charges and missiles when contacted by the molten metal jet from the penetration of a HEAT warhead, causing the entire ammunition load to explode.{{sfn|Warford|1995}} The flaw is mostly related to the spare ammunition in the turret, outside of the autoloader. The autoloaders have some ballistic protection, but only hold roughly half of a T-80s ammunition. During the [[First Chechen War|Chechen war]] 1994, the Russians were able to reduce their losses by having their tanks carry fewer rounds so that all the ammunition and propellant was stored in the autoloaders<ref>{{cite web | url=https://taskandpurpose.com/news/russian-tanks-ukraine-turrets-blown-off/ | title=Here's why Russian tanks keep getting decapitated in Ukraine | date=13 April 2022 }}</ref> This vulnerability may be addressed in later models. When modern Western tank designs changed from non-combustible propellant cartridges to semi-combustible, they tended to separate ammunition stowage from the crew compartment with armoured blast doors, and provided "blow-out" panels to redirect the force and fire of exploding ammunition away from the crew compartment.{{sfn|Warford|1995}}

This section lists the main models of the T-80, built in the Soviet Union, Russia and Ukraine, with the dates they entered service.

Command tanks with more radio equipment have ''K'' added to their designation for ''komandirskiy'' ("command"), for example, ''T-80BK'' is the command version of the T-80B. Versions with reactive armour have ''V'' added, for ''vzryvnoy'' ("explosive"), for example ''T-80BV''. Lower cost versions with no missile ability have a figure ''1'' added, as ''T-80B1''.
* '''T-80''' '''/ Object 219''' (1976): Initial model, with 1,000&nbsp;hp gas turbine engine, coincidence rangefinder, and no missile capability. This model does not have fittings for [[explosive reactive armour]]. The turret is from the T-64A, and thus retains the use of the old coincidence rangefinder. Characteristics of this type are the V-shaped water deflector on the front glacis, coincidence rangefinder in front of the commander's cupola, and Luna searchlight mounted in the same position as a T-64. Around 250 were produced, as the tank's armour was essentially obsolete when introduced.{{citation needed|date=April 2022}} Turret vs APFSDS – 380&nbsp;mm, hull vs APFSDS – 500&nbsp;mm (without reactive armour).<ref name="dokwar.ru">{{cite web |url=http://dokwar.ru/publ/vooruzhenie/bronetekhnika/osnovnoj_boevoj_tank_t_80/13-1-0-366|title=Основной боевой танк Т-80|website=dokwar.ru|access-date=5 December 2014|archive-url=https://web.archive.org/web/20141206202614/http://dokwar.ru/publ/vooruzhenie/bronetekhnika/osnovnoj_boevoj_tank_t_80/13-1-0-366|archive-date=6 December 2014|url-status=live}}</ref> This was, in effect, a pre-production model. It reportedly was fitted with an early version of the [[Shtora]] APS.
* '''T-80B''' '''/ Object 219R''' (1978): This model had a new turret with improved composite armour, laser rangefinder, new fire-control system, new autoloader and missile launcher system capable of firing [[9M112-1 Kobra]] antitank guided missile through the gun barrel.<ref name="all-tanks.ru"/> An improved, 1,100&nbsp;hp, engine was added in 1980, a new gun in 1982. A night sight TPNZ-49 in active mode reached 1,300 m and a passive – 850 m.<ref>{{cite web |url=http://worldweapon.ru/tank/t80.php|title=Основной танк Т-80 – Вооружение России и других стран Мира|website=worldweapon.ru|access-date=5 December 2014|archive-url=https://web.archive.org/web/20141208222719/http://worldweapon.ru/tank/t80.php|archive-date=8 December 2014|url-status=live}}</ref>
* '''T-80BV''' (1985): T-80BV (model 1985) is a T-80B upgraded with Kontakt-1 ERA on turret and hull. Smoke discharges are re-positioned to make a room on the turret for ERA. There is a new gun 2A46M-1 with 9K112 Kobra system capable of firing improved 9M112M Kobra ATGM through gun barrel. T-80BV also introduced a new 5 part armour array on the hull unlike the old 3 part T-80B. T-80B's were upgraded with [[Vehicle armour#Appliqué|appliqué]] armour 30mm high hardness steel plate to increase its protection to the same level.

* '''Object 219A''': Early T-80U (Object 219AS) variant. It has the T-80U's turret, but not the Kontakt-5 ERA. Instead, it uses the old Kontakt-1/3 system; some 219As did not have ERA at all. Often misnamed ''T-80A''.
* '''T-80U /''' '''Object 219AS''' (1985): Further development with a better turret, Kontakt-5 explosive reactive armour, improved gunner's sight. There is the same gun 2A46M-1 as on T-80BV but with a new 9K120 Svir system which allows firing [[9M119 Svir]] ATGM. In 1990, a new 1,250&nbsp;hp engine was installed. Overall protection with Kontakt-5 against APFSDS or HEAT is 780/1,320&nbsp;mm RHAe.{{sfn|Zaloga|2009|p=24}} 9K119M with antitank guided missile 9M119M installed since 1990. 
* '''T-80UD Bereza''' (1987): Ukrainian diesel version with 1,000&nbsp;hp 6TD engine and remote-controlled antiaircraft machine gun.
:* '''T-80UDK''' – T-80UD command tank. Prototype only.
:* '''Object 478BK''' – T-80UD with a welded turret.
:* '''Object 478BE''' – T-80UD sold to Pakistan.
:* '''Object 478DU2''' – Development of the T-80UD, that brought about a family of Ukrainian MBTs including [[T-84]], T-84U, T-84 Oplot, and T-84 Yatagan models.
* '''T-80UK''': Commander version equipped with Shtora-1 APS, thermal imaging night sight TO1-PO2T (detection range, target classification range = 6,400; 4,600 meters at night), new atmospheric parameter sensor, R-163U and R-163K radio stations, TNA-4 navigation system, HE shell remote detonation system, AB-1-P28 autonomous power plant. Adopted by the army in the 1990s.
*'''T-80UE''': Export version similar to T-80UK version, with Shtora-1 APS and other improvements, no orders received.
*'''T-80UE-1''': Not to be confused with the attempted export version T-80UE, this version is made by mating T-80UD turret with T-80BV hull (with some improvements to bring the hull to T-80U level, as Kontakt-5 ERA for example). Along with installation of PLISA thermal imaging sights, a new fire control system, and the more advanced and powerful 2A46M-4 125mm gun. The T-80UE-1 was adopted for service in 2005 and only a single battalion was ever equipped.
* '''T-80UM''' (1995): Russian version, with new Buran thermal imaging sight in place of the Luna IR.<ref name="fprado.com">{{cite web |url=http://www.fprado.com/armorsite/T-80U.htm|title=Fprado.com |website=www.fprado.com|access-date=26 June 2006|url-status=live|archive-date=9 July 2006|archive-url=https://web.archive.org/web/20060709054721/http://www.fprado.com/armorsite/T-80U.htm}}</ref>

* '''T-80UM-1 "Bars"''' (1997): Russian prototype with new [[Arena active protection system]]; bricks all around the turret visible on the outer side are Arena APS projectile casings, while Kontakt-5 ERA bricks lay behind them on the front part of the turret.
* '''T-80BVD''' (2002): KMDB's upgrade standard for Ukrainian T-80BVs. Changes include the 6TD diesel engine, remote-controlled commander's machine gun, and better optics. None were produced.
* '''T-80UM-2''': Russian experimental prototype with the older [[Drozd|KAZT Drozd-1 active protection system]]. In 2022, the only known prototype was destroyed by Ukrainian forces some time in March. This has been visually confirmed via photos taken by Ukrainian soldiers as well as the 3rd party monitoring site, [[Oryx (website)|Oryx]].<ref>{{Cite web |last=Oryx |title=Attack On Europe: Documenting Russian Equipment Losses During The Russian Invasion Of Ukraine |url=https://www.oryxspioenkop.com/2022/02/attack-on-europe-documenting-equipment.html |access-date=23 November 2024 |website=Oryx}}</ref>
