{{T-72 navigation}}
The '''T-90''' is a [[List of main battle tanks by generation#Third|third-generation]] Russian [[main battle tank]] developed from, and designed to replace the [[T-72]]. It uses a 125{{nbsp}}mm [[2A46 125 mm gun|2A46]] [[smoothbore]] [[tank gun|main gun]], the 1A45T [[fire-control system]], an upgraded engine, and gunner's [[thermal sight]]. Standard protective measures include a blend of steel and [[composite armour]], smoke grenade dischargers, [[Kontakt-5]] [[explosive reactive armour]] (ERA) and the [[Shtora]] infrared [[anti-tank guided missile]] (ATGM) jamming system. 

The T-90 was designed and built by [[Uralvagonzavod]], in [[Nizhny Tagil]], Russia. It entered service with the [[Russian Ground Forces|Russian army]] in 1992.

==Development==
The T-90 has its origins in a [[Soviet Union|Soviet]]-era program aimed at developing a replacement for the [[T-64]], T-72 and [[T-80]] series of main battle tanks (MBT). The T-72 platform was selected as the basis for the new generation of tank owing to its cost-effectiveness, simplicity and automotive qualities. The [[Uralvagonzavod|Kartsev-Venediktov Design Bureau]] from Nizhny Tagil was responsible for the design work and prepared two parallel proposals—the ''Object 188'', which was a relatively simple upgrade of the existing T-72B tank (''Object 184''), and the far more advanced ''[[Object 187]]''—only vaguely related to the T-72 series and incorporating major improvements to the hull and turret design, armor, powerplant and armament. Development work was approved in 1986 and the first prototypes were completed by 1988. The vehicles resulting from the ''Object 187'' program have not been declassified to this date.<ref>{{cite journal|last1=Szulc|first1=Tomasz|title=Ostatnie czołgi Związku Radzieckiego?|journal=Nowa Technika Wojskowa|date=August 2009|issue=9|pages=24–30}}</ref>

The Object 188 was engineered by a team under V.N. Venediktov. The biggest change was the integration of the 1A45 [[fire-control system]] of the T-80U. The Object 188 was initially designated as the T-72BM. The first four of these were delivered for trials in January 1989. An improved variant (called Upgraded T-72B<ref name=":2">{{Cite book |last=Устьянцев С.В., Колмаков Д.Г. |title=Т-72.Т-90.

Experience in creating domestic main battle tanks}}</ref>) was delivered beginning in June 1990. In March 1991, the [[Ministry of Defense (Soviet Union)|Soviet Ministry of Defense]] recommended that the Army adopt the Object 188. Work on the Object 187 was simultaneously stopped for unknown reasons.<ref>{{harvnb|Zaloga|2018|pages=7–8}}</ref>

==Production and service history==
[[File:T-90 snorkel.jpg|thumb|An early series T-90 with cast turret during a military exercise in Russia, demonstrating deep fording]]

Russian tank production dwindled in the years before and after the breakup of the Soviet Union. The [[Kharkov Locomotive Factory|Kharkov]] tank plant belonged to the newly independent [[Ukraine]], the [[Chelyabinsk Tractor Plant]] ended production in 1989, and [[Kirov Plant|Kirov]] in [[Saint Petersburg|Leningrad]] in 1990. In the two remaining tank plants at [[Omsktransmash|Omsk]] and [[Krasnoye Sormovo Factory No. 112|Nizhni-Tagil]], state orders all but ceased in 1992. Around the same time, the Russian Ministry of Defense decided it would commit to eventually producing just one tank type.<ref name="auto2">{{harvnb|Zaloga|2018|pages=4–5}}</ref>

During the 1980s, the Soviet military had ordered T-64s, T-72s and T-80s, then in simultaneous production from rival tank design firms. Though all three tanks had similar characteristics, they each required different components, which contributed to the Army's logistical burden.<ref name="auto2"/> Though both Nizhni-Tagil's T-90 and Omsk's T-80U had their merits, the T-80's [[gas turbine]] engine was notorious for its high fuel consumption and poor reliability. Additionally, Russian T-80s suffered heavy losses in their first combat use during the [[First Chechen War]]. T-90s, which were not deployed to Chechnya, were spared media criticism in spite of the similarly poor performance of the T-72 in the same conflict.<ref name="auto3">{{harvnb|Zaloga|2018|pages=16–17}}</ref>

In January 1996, Colonel General [[Aleksandr Galkin (general)|Aleksandr Galkin]], chief of the Main Armor 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="auto3"/>

The principal upgrade in the T-90 is the incorporation of a slightly modified form of the T-80U's more sophisticated 1A45T ''Irtysh'' fire control system and an upgraded V-84MS multi-fuel engine developing 840&nbsp;hp (618&nbsp;kW).<ref>{{harvnb|Zaloga|2018|pages=13–14}}</ref> The T-90 was manufactured at the Uralvagonzavod factory in Nizhny Tagil, with low-level production being carried out since 1992 and virtually ceasing towards the end of the 1990s for the native market. Around 120 T-90 tanks were delivered to the Russian Ground Forces before production of an upgraded version was resumed in 2004.<ref>{{harvnb|Zaloga|2018|pages=8,21,24}}</ref>

By September 1995, some 107 T-90 tanks had been produced, located in the [[Siberian Military District]].<ref>{{cite book |first=James M |last=Warford |title=The Russian T-90S: Coming into Focus |work=Armor |date=September–October 1997 |url=https://www.knox.army.mil/center/ocoa/armormag/backissues/1990s/1997/so97/5T90.pdf |publisher=US Army}} {{dead link|date=November 2013}}, quoting Russian newspaper sources</ref> Later, another U.S. report said that "..with only 150 built by mid-1998, the Siberian Military District's [[21st Motor Rifle Division]] received [some of] these MBTs and formed a tank regiment (T-90s were also issued to the 5th Don Guards Tank Division in Buryatia)."<ref>Adam Geibel, "Did the Rebels Misidentify Knocked-Out Tanks?," ''Armor Magazine'', November-December 2000, p.27</ref> However, the 21st MRD had already been reduced to the status of a motor-rifle brigade by this time, and then was reduced to a storage base in 1997.

Facing tapering domestic orders, Uralvagonzavod received government approval to export the T-90 in the mid-1990s. The designers at Uralvagonzavod created a new, welded turret that offered improvements in protection and internal space in the same period. In 1997, India signaled interest in the T-90 in response to Pakistan's acquisition of 320 Ukrainian T-80UD tanks. India's [[Heavy Vehicles Factory]] in [[Avadi]] was already license-manufacturing the T-72 under the name "Ajeya".<ref>{{harvnb|Zaloga|2018|pages=17–18, 20}}</ref>

The first 42 complete Indian tanks were delivered in 2001 and were designated '''T-90S''' ('''''Object 188S'''''), still equipped with the older cast turrets of the early series<ref>{{harvnb|Zaloga|2018|page=20}}</ref> (this exhausted the remaining stocks of cast turrets warehoused at Nizhny Tagil) and powered by the V-84 engine making 840&nbsp;hp (618&nbsp;kW).{{citation needed|date=April 2022}} In 2002, 82 vehicles were delivered, now equipped with the new welded turrets and the V-92S2 engine, generating 1,000&nbsp;hp (735&nbsp;kW). The initial contract stipulated the following batch of 186 tanks, now officially called '''Bhishma''', to be completed in India from Russian-supplied kits, and then gradually replaced with domestically manufactured parts. Delays in domestic production compelled the Indian authorities to place an additional order for 127 complete vehicles from Uralvagonzavod.<ref>{{harvnb|Zaloga|2018|pages=20–21}}</ref>

[[File:T-90A - Engineering Technologies 2012 -01.jpg|thumb|A Russian specification T-90A. The new welded turret with its angular geometry is clearly visible.]]
In 2005 the Russian army resumed delivery of the T-90, requesting the "original" specification for the vehicle with a cast turret. But with the new order numbering 14 tanks, and the large capital investment required to set up production of new cast turrets, the Russian Ministry of Defence agreed on a new configuration very close to the Indian T-90S, which was expeditiously accepted into service without any trials as the '''''Object 188A1''''' or '''T-90A'''.<ref>{{cite journal|last1=Szulc|first1=Tomasz|title=Nowe Czołgi Naszych Wschodnich Sąsiadów: T-90MS I Opłot-M|journal=Nowa Technika Wojskowa|date=September 2012|issue=9|pages=14}}</ref> 2005 saw delivery of 18 new tanks – enough to equip approximately five tank platoons. These new Russian tanks were powered by the V-92S2 engine, carried a T01-K05 ''Buran-M'' gunner's sight (passive-active night-vision channel with an EPM-59G ''Mirage-K'' matrix and a maximum observation distance of 1,800 m) and were protected by the most recent Kontakt-5 reactive armor with 4S22 explosive tiles.

The years 2006–2007 saw the delivery of 31 T-90A tanks each, now fitted with entirely passive ESSA main gunner's sights supplied by Peleng in [[Belarus]] and using the 2nd-generation thermal camera Catherine-FC from [[Thales Group|Thales]], and improved 4S23 ERA tiles. The joint venture established on the basis of JSC Volzhsky Optical and Mechanical Plant" (VOMZ) and Thales Optronics, produced Catherine-FC thermal imaging devices, which were further used to develop "ESSA", "PLISA" and "SOSNA-U" sighting systems produced for the Russian armoured vehicles, including T-72B3 tanks and export versions of T-90S (exported to India, Algeria and Azerbaijan). Since 2012, Russia was able to produce 3rd-generation Catherine-XP cameras based on QWIP matrix technology.<ref>{{cite web |url=https://defence-ua.com/index.php/en/publications/defense-express-publications/1182-paris-moscow-a-thorny-path-of-justified-sanctions |title=Paris-Moscow: A Thorny Path of Justified Sanctions |access-date=3 August 2018 |archive-url=https://web.archive.org/web/20180803224146/https://defence-ua.com/index.php/en/publications/defense-express-publications/1182-paris-moscow-a-thorny-path-of-justified-sanctions |archive-date=3 August 2018 |url-status=live}}</ref>

In 2012, the Russian-made commander combined sample supervisory-sighting system ''"T01-K04DT/Agat-MDT"'' was presented to the public at the International Forum Engineering Technologies 2012. According to Krasnogorsky Zavod plant, Agat-MDT has the ability to install (for further modernization) in the sight the newly developed domestic UPF format 640×512 by 15 microns, which makes possible in the future to extend the range of target identification at night to 3.5–4.0&nbsp;km without modifications to the sight.<ref name="survincity.com">{{cite web |url=http://survincity.com/2013/10/of-kmz-complex-produced-the-first-tank-with-a/ |title=Of KMZ complex produced the first tank with a domestic — Encyclopedia of safety |access-date=3 August 2018 |archive-url=https://web.archive.org/web/20180803141034/http://survincity.com/2013/10/of-kmz-complex-produced-the-first-tank-with-a/ |archive-date=3 August 2018 |url-status=live}}</ref>

In 2016, the Krasnogorsk plant finished testing the ''Irbis-K'' night-vision sighting system for the T-80U and T-90, with first deliveries planned for 2017. Completion of the Irbis-K, the first Russian-produced [[mercury cadmium telluride]] (MCT) matrix thermal sight, addressed a disadvantage of Russian tanks relative to their Western counterparts. The Irbis-K can identify targets at ranges up to 3,240 meters during day and night.<ref name="mil.today">{{cite web |url=http://mil.today/2017/Weapons52/ |title=T-90 Tanks to Get MCT-Matrix Heat-Vision Sight |date=14 May 2017 |access-date=16 July 2018 |archive-url=https://web.archive.org/web/20180716053931/http://mil.today/2017/Weapons52/ |archive-date=16 July 2018 |url-status=live}}</ref>

In 2007, there were about 334 T-90 tanks of various types serving in the Russian Ground Forces' [[5th Guards Tank Division]], stationed in the Siberian Military District, and seven T-90 tanks assigned to the marines.<ref name="warfare.ru">{{cite web|url=http://www.warfare.ru/?lang=&catid=244&linkid=1778|title=T-90/S MBT|access-date=19 October 2008|archive-url=https://web.archive.org/web/20071110070955/http://www.warfare.ru/?lang=&linkid=1778&catid=244|archive-date=10 November 2007|url-status=live}}</ref> Since 2008, the Russian army has received 62 tanks annually, suspending orders in 2011.

After the cancellation of the [[T-95]] in 2010, Uralvagonzavod began the OKR Armata (Armament) design study. The study resulted in the Object 148 based on the T-95 (itself based on the Object 187).

An early variant of the export-oriented T-90S allegedly saw combat action during the [[War of Dagestan|1999 Chechen invasion of Dagestan]] instead of being delivered to India. The tank's survivability against [[rocket-propelled grenade]]s (RPGs) is disputed. [[Gordon L. Rottman]] writes that T-90s were "frequently" knocked out by three or four hits from a [[RPG-7]]. He adds that Chechens found a way to compromise T-90s fitted with [[explosive reactive armor]]: they would fire an RPG-7 from close range (within 50m) to trigger the explosive reactive armor protection, and then re-attack the exposed tank armour underneath with two or more RPG hits, again from close range.<ref>{{cite book|title=The Rocket Propelled Grenade|series=Weapon 2|first=Gordon L.|last=Rottman|author-link=Gordon L.

On the other hand, ''[[Moscow Defense Brief]]'' gives the example of one T-90 that remained in action despite being hit by seven RPGs.

In 2001, India purchased 310 T-90S tanks from Russia, of which 124 were delivered complete (42 featured the early cast turrets seen on Russian tanks) and 186 were to be assembled from kits delivered in various stages of completion with an emphasis on shifting production to domestic means. The T-90 was selected because it is a direct development of the T-72 that India already manufactured, simplifying training and maintenance. India opted to acquire the T-90 to counter Pakistani deployment of the Ukrainian-made T-80 tank in 1995–97.<ref>{{harvnb|Zaloga|2018|pages=18,20}}</ref> These T-90S tanks were made by Uralvagonzavod and the engines were delivered by Chelyabinsk Tractor Plant. The Indian tanks however omit the [[Shtora-1]] passive electronic countermeasure system which was deemed obsolete.

A follow-on contract, worth [[US$]]800 million, was signed in October 2006, for another 330 T-90S ''Bhishma'' MBTs that were to be manufactured in India by [[Heavy Vehicles Factory]] at [[Avadi]], Tamil Nadu.{{cn|date=July 2024}}

The T-90M features the 'Kaktus K-6' bolted explosive reactive armour (ERA) package on its frontal hull and turret-top (the T-90S has 'Kontakt-5' ERA), is fitted with an enhanced environmental control system supplied by Israel's Kinetics Ltd for providing cooled air to the fighting compartment, has additional internal volume for housing the [[Cryogenics|cryogenic cooling]] systems for new-generation [[thermal imager]]s like the [[Thales Group|THALES]]-built Catherine-FC thermal imager (operating in the 8–12 micrometre bandwidth). In all, India plans to have 2,080 T-90 tanks in service by 2020.{{citation needed|date=February 2023}}

A third contract, worth $1.23 billion, was signed in December 2007 for 347 upgraded T-90Ms, most to be licence-assembled by HVF. The Army hoped to field a force of over 21 regiments of T-90 tanks and 40 regiments of modified T-72s. The Indian Army began receiving its first T-90M main battle tank in completely knocked-down form from Russia's Nizhny Tagil-based Uralvagonzavod JSC at the end of 2009.<ref>{{cite web|author=RIA Novosti Dmitry Korobeinikov |url=http://www.en.beta.rian.ru/mlitary_news/20090824/155910756.html |title=Indian army receives first T-90 tanks made under Russian license |publisher=RIA Novosti |date=24 August 2009 |access-date=7 February 2010 |url-status=dead |archive-url=https://web.archive.org/web/20090904203207/http://en.beta.rian.ru/mlitary_news/20090824/155910756.html |archive-date=4 September 2009}}</ref>

{{external media|video1={{YouTube|ipc9BBodqC8|Autoloader animation}}}}
The T-90's main armament is the [[2A46]]M 125mm [[smoothbore]] tank gun. This is a highly modified version of the [[Sprut anti-tank gun]], and is the same gun used as the main armament on the T-80-series tanks. It can be replaced without dismantling the inner turret and can fire [[armour-piercing fin-stabilized discarding sabot]] (APFSDS), [[high-explosive anti-tank]] (HEAT-FS), and [[high-explosive fragmentation]] (HE-FRAG) ammunition, and [[9M119M Refleks]] anti-tank guided missiles. The Refleks has [[semi-automatic command to line of sight]] (SACLOS) laser [[beam riding]] guidance and a [[Tandem-charge|tandem]] [[shaped charge]] HEAT warhead. It has an effective range of 100 m to 6&nbsp;km, and takes 17.5 seconds to reach maximum range. Refleks can penetrate about {{convert|950|mm}} of steel [[rolled homogeneous armour]] (RHA) and can also engage low-flying air targets such as [[helicopter]]s.{{citation needed|date=February 2023}}

The [[NSV machine gun|NSV]] 12.7mm ([[12.7×108mm|12.7×108]]) [[teleoperation|remotely controlled]] [[Anti-aircraft warfare|anti-aircraft]] [[heavy machine gun]] can be operated from within the tank by the commander and has a range of 2&nbsp;km and a cyclic [[rate of fire]] of 700–800 rounds per minute with 300 rounds available (the NSV was replaced by the [[Kord machine gun|Kord heavy machine gun]] in the late 1990s). The [[PK machine gun|PKMT]] 7.62mm ([[7.62×54mmR]]) [[coaxial gun|coaxial machine gun]] weighs about 10.5&nbsp;kg while the ammunition box carries 250 rounds (2,000 rounds carried) and weighs an additional 9.5&nbsp;kg.{{citation needed|date=February 2023}}

Like other modern Russian tanks the 2A46M in the T-90 is fed by an [[Autoloader|automatic loader]] which removes the need for a manual loader in the tank and reduces the crew to 3 (commander, gunner, and driver). The autoloader can carry 22 ready-to-fire rounds in its carousel and can load a round in 5–8 seconds.{{citation needed|date=February 2023}} It has been suggested that the automatic loaders on modern T-90 tanks have been modified to take advantage of newer ammunition such as the [[125 mm smoothbore ammunition#3VBM19/3BM42M (3BM44M)|3BM-44M]] APFSDS, which like the US [[M829 (munition)#M829A3|M829A3]] penetrates armour better than the previous shorter rounds. HEAT rounds that can be fired from the 2A46M includes the [[125 mm smoothbore ammunition#3BK21B|3BK21B]] (with a [[depleted uranium]] liner), [[125 mm smoothbore ammunition#3VBK25/3BK29|3BK29]] (with a credited penetration of 800mm RHA equivalency), and the [[125 mm smoothbore ammunition#3VBK27?/3BK29M|3BK29M]] (with a Triple-tandem charge warhead). Additionally the T-90 features the Ainet [[smart grenade|fuse setting system]] which allows the tank to detonate [[125 mm smoothbore ammunition#3VOF36/3OF26|3OF26]] HE-FRAG rounds at a specific distance from the tank as determined by the gunner's [[laser rangefinder]], improving its performance against helicopters and [[infantry]].<ref>{{cite web |title=125mm APERS And Special Rounds |publisher=Fofanov.armor.kiev.ua |url=http://fofanov.armor.kiev.ua/Tanks/ARM/apers/ammo.html |access-date=8 July 2010 |url-status=live |archive-date=4 December 2010 |archive-url=https://web.archive.org/web/20101204130029/http://fofanov.armor.kiev.ua/Tanks/ARM/apers/ammo.html}}</ref> Accurate firing range of the HE-Frag-FS 10&nbsp;km, APFSDS 4&nbsp;km.<ref>{{cite web |url=http://dokwar.ru/publ/bronetekhnika/sravnenie_tankov_altay_leopard_2a_t_90/13-1-0-45|title=Сравнение танков – Altay, Leopard 2a, Т-90|access-date=15 November 2014|archive-url=https://web.archive.org/web/20141006081430/http://dokwar.ru/publ/bronetekhnika/sravnenie_tankov_altay_leopard_2a_t_90/13-1-0-45|archive-date=6 October 2014|url-status=dead}}</ref>

Fire-control system of the T-90 showed the following features of combat shooting during state testing. Heavily armoured targets at ranges of up to 5&nbsp;km were hit by tank T-90 on the move (up to 30&nbsp;km/h) with a high probability of hit with the first shot. During state testing made 24 launches of missiles at ranges of 4–5&nbsp;km and they all hit the target (all missile launches were made by inexperienced professionals). An experienced gunner at speeds of 25&nbsp;km/h hit 7 real armoured targets located at ranges of 1,500–2,500 m and 54sec.<ref>{{cite web|url=http://armor.kiev.ua/Tanks/Modern/T90/t90_1.php|title=T-90|access-date=15 November 2014|archive-url=https://web.archive.org/web/20141127215530/http://armor.kiev.ua/Tanks/Modern/T90/t90_1.php|archive-date=27 November 2014|url-status=live}}</ref><ref>{{cite web |url=http://www.sinopa.ee/sor/boraznoe/t90/t9002.htm |title=ÈÑÏÛÒÀÍÈßÒÀÍÊÀ Ò-90|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>

Fire-control system on the T-90 includes the PNK-4S/SR AGAT day and night sighting system mounted at the commanders station which allows for night time detection of a tank sized target at ranges between 700 and 1100 metres depending on the version of the sight. Early models of the T-90 were equipped with the TO1-KO1 BURAN sight but later models (T-90S) were upgraded to use the ESSA [[thermal imaging]] sight, which allows for accurate firing to a range of 5,000–8,000m during day and 3,300m during night, using the CATHERINE-FC [[thermal camera]] produced by [[Thales Optronique]]. The gunner is also provided with the 1G46 day sighting system which includes a laser range finder, [[missile guidance]] channel and allows tank-sized targets to be detected and engaged at {{convert|5|to|8|km}}.

In 2012, the Russian-made combined sample of commander supervisory-sighting system T01-K04DT/Agat-MDT was presented to the public. According to Krasnogorsky Zavod (plant), Agat-MDT has the ability to be installed (for further modernization) in the sight of the newly developed domestic UPF format 640×512 by 15 microns, which is possible in the future to extend the range of target identification at night to 3.5–4.0&nbsp;km without sight modifications.<ref name="survincity.com"/> In 2016, the Krasnogorsk plant finished testing the ''Irbis-K'' night-vision gunner's sighting system for the T-80U and T-90, with first deliveries in 2018.<ref>{{Cite web |url=http://www.armstrade.org/includes/periodics/news/2018/0914/101548713/detail.shtml |title=ЦАМТО / Новости / Россия полностью заместила французские комплектующие для танковых прицелов |access-date=18 September 2018 |archive-url=https://web.archive.org/web/20180918194108/http://www.armstrade.org/includes/periodics/news/2018/0914/101548713/detail.shtml |archive-date=18 September 2018 |url-status=live}}</ref> Completion of the Irbis-K, the first Russian-produced mercury-cadmium-telluride (MCT) matrix thermal sight, will bridge a gap with the leading NATO countries in this area.

The Russian-made thermal imaging device not only meant that Russian tanks would no longer need to be equipped with foreign parts, but it also meant that complete tank modernization was cheaper. Furthermore, there will be no decrease in demand for the [[T-72]] and the T-90 in the next few years. The new tank gunner’s heat-vision sight Irbis-K and the commander’s combined sighting and observation system Agat-MDT can be supplied to T-72, T-80 and T-90 upgraded versions (T-72B3M, T-80BVM, T-90M...), replacing the Thales Catherine-FC thermal camera.

[[File:T-90 engine.jpg|thumb|The T-90's diesel engine]]

The [[Engine|prime mover]] is the {{ill|V-92S|es|B-92}} [[diesel engine]], built in the Chelyabinsk Tractor Plant. Different models of the T-90 tank are powered by various motors in its initial models, like the V-84MS 618&nbsp;kW (840&nbsp;hp) [[Four-stroke engine|four-stroke]] [[V12 engine|V-12]] [[Reciprocating engine|piston engine]], uprated {{convert|1000|hp|abbr=on}} engines and {{convert|1250|hp|abbr=on}} engines made by Uralvagonzavod and are delivered by Chelyabinsk Tractor Plant. The Т-90S with {{convert|1000|hp|abbr=on}} engine can attain a top speed of 60&nbsp;km/h on the road and up to 45&nbsp;km/h on rough terrain. The T-90 tank has a typical drivetrain arrangement, with a rear placed engine and transmission. The {{convert|1000|hp|abbr=on}} engines are V-92 four stroke, 12 cylinder, [[Multifuel|multi-fuel]] diesel while the {{convert|1250|hp|abbr=on}} engine is V-96. The T-90 export version i.e. modified T-90S is fitted with an increased power multi-fuel {{convert|1000|hp|abbr=on}} diesel engine with [[turbocharger]]s. The tank has an [[HVAC|air conditioning system]] for work in hot places.{{citation needed|date=February 2023}}

===Protection===
[[File:T-90-ET 2010.jpg|thumb|A T-90A fitted with second generation [[Kontakt-5]] [[explosive reactive armour|ERA]]]]
[[File:Indian Army T-90.jpg|thumb|A T-90S Bhishma of the Indian Army is fitted with a "two-tiered" protection system: the first tier is the composite armour in the turret, second tier is third generation [[Kontakt-5]] ERA.]]

The T-90 has a "three-tiered" protection system. The first tier is the [[composite armour]] in the turret, consisting of basic armour shell with an insert of alternating layers of aluminum and plastics and a controlled [[Deformation (engineering)|deformation]] section.{{citation needed|date=February 2023}}

The second tier is third generation Kontakt-5 [[explosive reactive armour]] (ERA) bricks which degrade the penetrating power of kinetic-energy APFSDS ammunition. These bricks give the turret a distinctive angled "clam shell" appearance. ERA bricks are also located on the turret roof to protect against attacks from above. The turret's forward armour package, in addition to the ERA and steel plating, includes Russian composite armour sandwiched between upper and lower steel plates. Composite armour offers lower weight and better protection than steel-only armour.{{citation needed|date=February 2023}}

The third tier is a [[Shtora]]-1 (Russian: Штора-1 or "curtain" in English) [[Countermeasure|countermeasures suite]], produced by Elektromashina of Russia. This system includes two electro-optical/IR "[[Dazzler (weapon)|dazzlers]]" (i.e. [[Infrared countermeasure|active infrared]] jammer) on the front of the turret (which gives the distinctive "Red Eyes"), four [[laser warning receiver]]s, two 3D6 [[smoke grenade|'smoke' grenade]] [[Grenade launcher|discharging systems]] and a computerised control system. The Shtora-1 warns the tank's crew when the tank has been '[[Laser designator|painted]]' by a [[laser guidance|weapon-guidance laser]] and allows the crew to slew the turret to face the threat. The infrared jammer, the TShU1-7 EOCMDAS, jams the semi-automatic command to line of sight (SACLOS) guidance system used by some anti-tank guided missiles. The smoke grenades are automatically launched after Shtora detects that it has been painted. The smoke grenades are used to mask a tank from laser rangefinders and designators, and the optics of other weapon systems. Indian T-90S tanks are not equipped with the Shtora-1 countermeasures suite.{{citation needed|date=February 2023}} They will be equipped with the Land Electronic Defence System [[LEDS-150]].

In addition to the passive and active protection systems, the T-90 is also fitted with nuclear, biological and chemical ([[NBC (weapon)|NBC]]) protection equipment, KMT [[Mine plow|mine sweeps]] and an [[Automatic fire suppression|automatic fire suppression system]].{{citation needed|date=February 2023}} The [[EMT-7]] [[Directed-energy weapon|electromagnetic-counter mine system]] can also be installed on the T-90.<ref>{{cite web |url=http://www.janes.com/articles/Janes-Mines-and-Mine-Clearance/EMT-7-electromagnetic-countermine-system-Russian-Federation.html |title=EMT-7 electromagnetic countermine system (Russian Federation) |work=Jane's |date=20 June 2011 |access-date=11 September 2011 |archive-url=https://web.archive.org/web/20100406035925/http://www.janes.com/articles/Janes-Mines-and-Mine-Clearance/EMT-7-electromagnetic-countermine-system-Russian-Federation.html |archive-date=6 April 2010 |url-status=live}}</ref> EMT-7 emits an [[electromagnetic pulse]] to disable magnetic mines and disrupt electronics before the tank reaches them.

The T-90A / T-90S turret uses a stronger steel alloy, giving an approximately 10–15% increase in the protection level given from the steel elements of the armor array; as the array from many aspects is not wholly steel, the overall increase in protection is less than this margin over these areas.<ref>{{cite web |url=http://www.uvz.ru/products/t90-s |title=ТАНК Т-90С: ОСНОВНОЙ БОЕВОЙ ТАНК |access-date=10 December 2018 |archive-url=https://web.archive.org/web/20180504074545/http://www.uvz.ru/products/t90-s |archive-date=4 May 2018 |url-status=dead}}</ref><ref>{{cite web |url=http://btvt.narod.ru/4/armor.htm |title=Бронирование современных отечественных танков |access-date=26 May 2017 |archive-date=25 May 2017 |archive-url=https://web.archive.org/web/20170525213624/http://btvt.narod.ru/4/armor.htm |url-status=live}}</ref> Protection values will decrease somewhat against Tandem HEAT or penetrators with precursor tips.

====Turret issues====
The T-90 has an unknown issue that causes it to become disabled via the turret spinning uncontrollably. Currently there is no concrete understanding of what precisely causes this issue, but a theory by a former tank commander of the British Army, Hamish de Bretton-Gordon, states: “It’ll likely be a combination between inexperienced crews and poor electronics.”<ref name="a801">{{cite web |last=Barnes |first=Joe |date=27 May 2024 |title=Russia's most modern battle tank hit by 'disco head' glitch |url=https://www.telegraph.co.uk/world-news/2024/05/27/russias-most-modern-battle-tank-hit-by-disco-head-glitch/ |access-date=1 June 2024 |website=The Telegraph}}</ref>
