| − | ' | + | Overall, the armor protection of the T-90A can be considered almost the same as in the [[T-72B3]] and [[T-80U]]. However, despite hull being exactly the same as the T-72B3 with same thickness, composition and add-on armor, the turret of the T-90A shows a new turret design which can be considered as better due to the armor layout and composition. The T-90A, as the T-72B (1989) and T-72B3, has access to the Kontakt-5 (K5) ERA. This ERA (different from Relikt and Kontakt-1 seen in other T-72B series) has the particuliarity that has stopping power against darts (similar to Dorchester). Different from other T-72's, the T-90A has a rolled homogenous armor turret with spacing for composite armor blocks rather than built-in. Fuel tanks on either side of the driver can soak up some shrapnel and add to the overall survivability although they are most likely to be lit on fire if hit with HEAT-FS or an ATGM. However, as with all Russian auto-loaded MBTs, there are only three crew members so a well-placed shot is capable of causing a crew knock-out. Despite having a carousel autoloader which is not protected by any blast shield like on the Leclerc and Type 90 MBT's, it is harder to ammo rack compared to the T-80's specially since the ammo is scattered horizontally one on top of each other ("=" in this shape) and not in an L shape (in which charges are vertical and projectiles are horizontal. This reduces the chances of ammo rack compared to the T-80's. However, all side shots done to the hull will be lethal regardless of the carousel as said shot will take your two crew members. The ERA offers a really good protection for chemical energy penetrators such as HEAT-FS, ATGMs and anti-tank grenades, having a protection of 420 mm against chemical energy and 120 mm agaisnt kinetic energy. This makes the tank capable of withstanding hits of all HEAT-FS of the BR (most of them penetrate between 320 mm to 480 mm) and ATGMs (between 400 mm to 1000mm). It should be noted that ERA itself cannot stop all the spalling created by the premature explosion, the armor plating is what stops the spalling in case the ATGM has more penetration than what the K5 can withstand. |

| + | === Shtora-1 Active Protection System === | ||
| + | The T-90A has access to an infra-red jammer, the Shtora-1 APS. It is a constant active APS which provides protection against a wide variety of threats. The scanner-type jamming device (also known as "doom eyes" or "Russian eyes") is mounted on the front of the turret to cover the vulnerable frontal arc. It called "Infrared Countermeasure" for the following reason: SACLOS guidance utilizes a beam-riding guidance which is connected to the GPS (gunner main sight in some cases, on others it is a different sight like on [[T-55AM-1]] and [[T-62M-1]]) which uses a flare as reference point for the guidance system in the ATGM. The missile moves with the gunner's sight and the flare tries to stay on the crosshairs. IRCM confuses the GPS with a brighter IR light decoy acting as the flare (the flare is also IR) which signals the ATGM to move to a different position nowhere near from the gunner's target. The Shtora-1 APS has a minimum jamming range of roughly 50 m, meaning it will only deviate ATGMs past 50 m although it depends on the ATGM speed and ATGM angle of attack. This is the approximate distance between all ATGM in-game but it may vary. It will be able to jam a missile launched by a [[Swingfire]] faster due to its launch speed and flight path than an [[M3 Bradley]]. Shtora-1 has a field of view of 360 degrees horizontally (due to being turret mounted) and –5 to +25 degrees in elevation. | ||

In order to let the APS work, it must be tuned on with a key in the control section. The APS can be destroyed. Shtora-1 can be used while on the move (although turret must be facing the enemy). While on the move (specially horizontally), the jammed ATGM will move in an uncontrolled direction like normal jamming but riskier, keep this in mind as it can hit a track, engine deck or close enough to create fragmentation and mark the tank and/or friendlies. When moving forward to an enemy who fired an ATGM, it will be affected by the APS but due to the momentum, the ATGM can hit the if the ATGM is redirected towards the ground. Shtora-1 creates a thermal signature which can be seen with thermal sights. It also can also be used as an IR spotlight (as shown in picture). It should be noted that this can be a disadvantage when in night maps as tanks with NVD (except when tanks are using thermal view) will be able to see the light beam. The APS should be turned on and off at commander's discretion. When on day maps, this will not be an issue. Shtora must have a clear line-of-sight with the enemy launcher (at least enemy sights must be able to see the tank). Tanks firing behind cover like the Swingfire can also be affected by the APS. As long as the enemy is within the jamming arc, the T-90 will be protected against SACLOS ATGMs. Different from [[AMX-30B2 BRENUS]], the T-90A has access to a Laser Warning Reciever (LWR) which lets the commander know when there is a laser aiming at them. The LWR will be triggered by laser rangefinders, laser guided ATGM and laser lock-on by helicopters. This is particullary helpful the commander will know when it is being aimed at and engage the target with the main gun or jam incoming ATGMs. When facing laser guided missiles such as AGM-114 Hellfire, the Shtora-1 will not work. However, the LWR will trigger and the commander will be able to pop smoke '''(do not use ESS)''' and disrupt the laser lock-on. This does not only works for Hellfires but for PARS IR guided ATGM (main ATGM used in the [[EC-665 Tiger UHT]]) as the smoke disrupts the thermal signature. | ||

Description
The Т-90А is a rank VII Soviet medium tank with a battle rating of 11.0 (AB/RB/SB). It was introduced in Update "New Power".
General info
Survivability and armour
Overall, the armor protection of the T-90A can be considered almost the same as in the T-72B3 and T-80U. However, despite hull being exactly the same as the T-72B3 with same thickness, composition and add-on armor, the turret of the T-90A shows a new turret design which can be considered as better due to the armor layout and composition. The T-90A, as the T-72B (1989) and T-72B3, has access to the Kontakt-5 (K5) ERA. This ERA (different from Relikt and Kontakt-1 seen in other T-72B series) has the particuliarity that has stopping power against darts (similar to Dorchester). Different from other T-72's, the T-90A has a rolled homogenous armor turret with spacing for composite armor blocks rather than built-in. Fuel tanks on either side of the driver can soak up some shrapnel and add to the overall survivability although they are most likely to be lit on fire if hit with HEAT-FS or an ATGM. However, as with all Russian auto-loaded MBTs, there are only three crew members so a well-placed shot is capable of causing a crew knock-out. Despite having a carousel autoloader which is not protected by any blast shield like on the Leclerc and Type 90 MBT's, it is harder to ammo rack compared to the T-80's specially since the ammo is scattered horizontally one on top of each other ("=" in this shape) and not in an L shape (in which charges are vertical and projectiles are horizontal. This reduces the chances of ammo rack compared to the T-80's. However, all side shots done to the hull will be lethal regardless of the carousel as said shot will take your two crew members. The ERA offers a really good protection for chemical energy penetrators such as HEAT-FS, ATGMs and anti-tank grenades, having a protection of 420 mm against chemical energy and 120 mm agaisnt kinetic energy. This makes the tank capable of withstanding hits of all HEAT-FS of the BR (most of them penetrate between 320 mm to 480 mm) and ATGMs (between 400 mm to 1000mm). It should be noted that ERA itself cannot stop all the spalling created by the premature explosion, the armor plating is what stops the spalling in case the ATGM has more penetration than what the K5 can withstand.
Shtora-1 Active Protection System
The T-90A has access to an infra-red jammer, the Shtora-1 APS. It is a constant active APS which provides protection against a wide variety of threats. The scanner-type jamming device (also known as "doom eyes" or "Russian eyes") is mounted on the front of the turret to cover the vulnerable frontal arc. It called "Infrared Countermeasure" for the following reason: SACLOS guidance utilizes a beam-riding guidance which is connected to the GPS (gunner main sight in some cases, on others it is a different sight like on T-55AM-1 and T-62M-1) which uses a flare as reference point for the guidance system in the ATGM. The missile moves with the gunner's sight and the flare tries to stay on the crosshairs. IRCM confuses the GPS with a brighter IR light decoy acting as the flare (the flare is also IR) which signals the ATGM to move to a different position nowhere near from the gunner's target. The Shtora-1 APS has a minimum jamming range of roughly 50 m, meaning it will only deviate ATGMs past 50 m although it depends on the ATGM speed and ATGM angle of attack. This is the approximate distance between all ATGM in-game but it may vary. It will be able to jam a missile launched by a Swingfire faster due to its launch speed and flight path than an M3 Bradley. Shtora-1 has a field of view of 360 degrees horizontally (due to being turret mounted) and –5 to +25 degrees in elevation.

Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- Shtora active protection system prevents otherwise lethal missiles from hitting the tank, ensuring that the tank's reactive armour lasts longer
- Impressive protection thanks to the ERA
- Very strong turret
- Access to the unlockable 3BM42M shell with very good penetration
Cons:
- Active protection system only covers whatever the turret is facing, meaning that you can still be blindsided by canny missile users
- Worst acceleration and top speed out of all top tier Russian MBTs
- Gun mantlet still a huge, and well known, weakspot
- Cramped interior, easy to one shot
- Gun depression and elevation next to non-existent
- Shtora active protection system dosen't work for wire-guided missiles
History
Devblog
In 1989, the Ural Design Bureau of Heavy Engineering developed a prototype of a modernized T-72B tank, designated as "Object 188". The vehicle was a deep modification of the Soviet main battle tank, with a number of modern technical solutions, including a new fire control system, guided weapons, combined protection and a completely innovative electro-optical active protection system. The tank successfully passed tests and was recommended for mass production under the designation T-90; its serial production began in 1992. Meanwhile, the systemic economic crisis in Russia forced the tank builders to stop serial production of the tank. Meanwhile, research and development on a further T-90 modernization continued for the needs of foreign operators, as well as the Russian Army. Soon, when the economic situation in the industry began to improve, the tank builders combined their developments into an upgrade program, the T-90A. Unlike the basic version, the new tank featured a slightly more powerful engine, and a welded turret with improved protection. The main difference is the increased fire potential: a new cannon and a modern fire control system with an advanced thermal imaging sight. The T-90A tank was produced from 2004 to 2011.
