The first army to own the T-90S was India, with the largest numbering up to more than 300 and it was reported that they would continue to buy more even though the Indian tanks were not equipped with the Shtora-1 passive electronic countermeasure system. The original T-90s of the 1990s are now modernized. The new export version is equipped with an improved welding turret, ESSA thermal imaging sight, a more powerful engine and a new powertrain.

T-90 tanks themselves can be considered as Russian weapons masterpieces in the 21st century that have been tested on the fierce battlefield in Syria. Basically the T-90S has a low profile similar to the early Russian tanks, most of the details are similar to the original T-90. A low circular turret in the middle of the hull, equipped with both active and passive protection system, makes the T-90S the best protected tank in the world. Depending on the requirements of customers, the T-90S will be further customized with different equipment, its fighting ability is not inferior, even surpassing the T-90A.

Basically, the self-defense system on T-90S consists of 4 layers: the first is the Shtora-1 passive electronic countermeasure system to defend against laser or infrared guided missiles as well as jamming the target guidance systems. The second layer of defense is the Arena-E active protection system, which uses Doppler radar to detect incoming warheads and intercept them. The third layer is an external explosive reactive armor, and finally, the armor is a combination of high-strength steel and composite.

The true power of the T-90S armor is still a secret, but according to some estimates, the T-90A’s front armor has the equivalent strength of 550 to 650 mm of RHA steel when dealing with APFSDS shells or 750 mm with HEAT shells. When equipped with 2nd generation Kontakt-5 explosive reactive armor, this parameter can be increased from 800 to 830 mm with APFSDS and 1,150 to 1,350 mm with HEAT. Other areas of the tank are thinner armor and protection is generally weaker, but it is also difficult to defeat it if using only old-style anti-tank weapons.

The T-90S uses special coatings, made of electromagnetic wave-absorbing material, minimizes sources of thermal, electromagnetic and infrared radiation, making it difficult for enemy reconnaissance devices to detect. In addition, the T-90S is also fitted with NBC protection system, KMT mine sweeps and an automatic fire suppression system.

The anti-aircraft machine gun is controlled inside the vehicle, the gunner can aim while sitting inside the tank without having to stick out of the turret, reducing the possibility of casualties. The gun has a rate of fire of 650 to 750 rounds per minute, a range of 2 km. In addition, the T-90S is also equipped with shotguns and 10 F-1 grenades fitted inside the vehicle compartment for the crew to use in case they have to leave the tank and go out.
