Description

The T-90K Russian Main Battle Tank (MBT) is the commander's version of the T-90, with additional communication (station R-163-50K) and navigation equipment (TNA-4-3). Distinguishing features As a command vehicle, the T-90K carries different communications systems to the standard T-90. This can assist in distinguishing the vehicle as it will carry additional antennae on the roof of the turret. However, the T-90K will generally be almost identical to the T-90 to avoid the easy location and targeting of command vehicles. Armament The weapons carried are identical to the T-90, but the additional command equipment limits the space for stored ammunition to 34 rounds instead of 42 rounds in the standard version. Earlier Russian command vehicles, such as the T-80K, also lost the ability to fire the gun-launched guided missile. It is unclear if this effect is carried on with the T-90K but could be a possibility.

Variants

T-90A Russian army version with welded turret, V-92S2 engine and ESSA thermal viewer. Sometimes called T-90 Vladimir, in honor of its chief designer Vladimir Potkin

T-90AK Command version of T-90A.

T-90AM Latest version of the T-90A.[77] The main features include the modernisation of the old turret design, which is equipped with a new advanced fire control system "Kalina" (with integrated combat information and control systems), a new automatic loader and a new upgraded gun 2A46M-5, as well as a remote-controlled anti-aircraft gun "UDP T05BV-1". The new version also includes the Relikt (Реликт (динамическая защита) ERA bricks instead of the Kontakt-5 ERA bricks.

Т-90M New modernized version of Т-90А. It's a program of modernization of Vladimir tanks and will include 400 tanks currently in service. Tanks will receive 2А82-1М gun (same as in T-14) and fire control system Kalina. They will be upgraded with Afghanit APS and Relikt ERA. The upgrades are also aimed at improving network-centric warfare capabilities and coordination with Armata project vehicles. The first contract was signed in 2017 and serial production started in 2018.

T-90S Export version of the T-90, later adopted by the Russian Armed Forces as the T-90A. These tanks were made by Uralvagonzavod and were updated with 1,000 hp (750 kW) engines made by Chelyabinsk Tractor Plant. These tanks carry a leaner version of the Shtora-1 passive/active protection system which lacks the infra-red dazzlers carried on the turret. Sometimes called T-90C (Cyrillic letter es looks like a Latin c). These were initially supplied with cast turrets of the early T-90, and when stocks were depleted, new, welded turrets were fabricated.

T-90SK Commander's version of the T-90S, with additional communication and navigation equipment. It differs in radio and navigation equipment and Ainet remote-detonation system for HEF rounds.

T-90S "Bhishma" – modified T-90S in Indian service.

T-90MS Also known as T-90SM is an updated version of the T-90S. It is equipped with a 1,130 hp engine, a PNM Sosna-U gunner view. a UDP T05BV-1 RWS with a 7.62 mm machine gun, GLONASS, inertial navigation systems, new Relikt explosive reactive armour (ERA) that covers more of the tank, and a steering wheel. A new removable turret bustle is included, which provides storage for eight additional rounds. The T-90MS is ready for serial production.[88] 4 video cameras provide a 360° view of the environment, while the tank is more connected to command. The T-90MS has an upgraded thermal imager that can detect tanks over 3300 meters away.
