The Russian T-90 Main Battle Tank Background
During the 1970’s two new main battle tanks entered production and service with the Soviet Union, the T-72 and T-80.
The T-72 (built by Uralvagonzavod) was a fairly simple design that was easy and quick to build in greater numbers. It was widely deployed amongst the Russian Army and the export T-72M version was built under licence in a number of WARSAW Pact countries as well as being sold to friendly nations.
The second MBT (built by Omsktransmash) was the T-80, which was regarded as a more sophisticated design, having superior protection, firepower and increased mobility.
With the dissolution of the Soviet Union and creation of the Russian Federation in 1991, tank production suffered at both manufacturers.
The Russian T-90 Tank Development
The design Bureau at Uralvagonzavod set about improving the T-72B design by incorporating the T-80U armour and Shtora-1 suite as well as its fire control systems. A new engine with more Horse Power was added and the main gun upgraded to the 2A46M type.
The upgraded tank was called the T-72BM. It entered low number production for the Russian Army in 1993 under the designation T-90.
The T-90 Main Battle Tank
The turret and hull is fitted with composite armour and with the latest (at the time) Kontakt-5 Explosive Reactive Armour.
It was fitted with the Shtora-1 countermeasure suite. It has 4 sensors that detect if a laser range finder (used by tanks and anti-tank missiles launchers to aim at a tank) is pointing at the vehicle, it then alerts the crew and slays the turret round in the direct the laser is coming from.
The systems two jammers aka “dazzlers” (boxes, 1 either side of the main gun that have a red circle when activated) then activate disrupting the laser or missile guidance, making the T-90 a harder target to hit. The system also fires from its smoke grenade launchers an aerosol smoke screen opaque to infrared light.
The system also ensures that the most heaviest armoured part of the tank is facing the threat and the crew can engage the threat.
The vehicle also a complete NBC system in the fighting compartment.
The main gun is a 125mm calibre smoothbore 2A46M. It is capable of firing 2 part APFSDS, HEAT-FS and HE-FRAG rounds. The main gun is fed by an autoloader, which has a carousel with 22 rounds. Additional 20 rounds are stored in the vehicle.
The main gun is capable of firing the 9M119M Refleks anti-tank guided missile, which has a tandem charge and semi-automatic guidance giving the T-90 an effective firing range of 6 km’s.
The Fire Control System uses the PNK-4S/SR AGAT day and night sighting system with a TO1-KO1 BURAN sight. The gunner uses the 1G46 day sighting system and the driver users a TVN-5 day and night sight.
Secondary weapons include a coaxial 7.62mm machine gun and the commander can operate the NSV 12.7mm MG mounted on the turret roof from under armour.
Powered by a V-84MS Diesel engine generating 840 HP and torsion bar suspension, the vehicle was publicly shown jumping of high jumps at various shows and earnt the nickname the flying tank. It can be fitted with wading equipment.
T-90K Main Battle Tank
Command version of the T-90, fitted with additional communication and navigation equipment.
T-90A Main Battle Tank
The first major upgrade, the T-90 cast turret was replaced with a new all-welded one. some changes were made to the hull’s armour and it is not known if any were made to the new turret.
A new ESSA thermal imaging sight was installed, which had an improved view range. Mobility was also improved with a new 1000 HP V-92S2 diesel engine.
Production started in 1999 and has been the main variant model in the Russian Army.
T-90AM Main Battle Tank
Though the T-90 series is operated by Russia, its been a greater success on the export market. Uralvagonzavod in 2013 unveiled there latest export model, the T-90S Modernised aka T-90SM (as stated by the manufacturer).
The T-90AM is a speculated designation started online (since the unveiling of the T-90SM) of a T-90A that would receive the same upgrades applied to the T-90S (the export model of the T-90A) that resulted in the T-90SM.
The T-90AM is not mentioned in press release or product list by the manufacturer, nor an upgrade purchased by the Russian Army. In fact the T-90A has not been ordered by Russia since 2010 and the Armata Universal Combat Platform has now been unveiled in 2015, which will be manufactured by Uralvagonzavod.
