T-90S Main Battle Tank (MBT)
UralVagonZavod - Russia
The T-90S is the latest development in the T-series of Russian tanks
and represents an increase in firepower, mobility and protection. It is
manufactured by Uralvagonzavod in Nizhnyi Tagil, Russia.
The T-90S entered service with the Russian Army in 1992. In February
2001, the Indian Army signed a contract for 310 T-90S tanks: 124 were
completed in Russia and the rest are being delivered in "knocked down"
form for final assembly in India.
T-90S main battle tank orders and deliveries
The first of these was delivered in January 2004. The locally
assembled tanks are christened 'Bhishma'. The tanks are fitted with the
Shtora self-protection system and Catherine thermal imagers from Thales
of France and Peleng of Belarus. The first ten Bhishma tanks were
inducted into the Indian Army in August 2009. India plans to induce
1,640 T-90 tanks by 2020.
In January 2005, it was announced that a further 91 T-90S tanks would
be procured for the Russian Army, although this number was later
reduced.
By November 2007, it has been estimated that the Russian Army has
around 200 T-90 tanks. In August 2007, Thales was awarded a contract to
supply 100 of these with the Catherine FC thermal imager. In March 2006,
Algeria signed a contract for the supply of 180 T-90S tanks from
Uralvagonzavod, to be delivered by 2011. Of the total, 102 tanks were in
service with the Algerian Army by 2008.
In November 2006, India ordered a further 330 T-90 tanks, to be licence-built by heavy vehicle factory (HVF), Avadi, Tamil Nadu.
In January 2009, the Greek Cypriot Government approved the purchase
of 41 T-90 tanks from Russia. In March 2010, however, the government
changed its plans and opted for T-80 tanks against the T-90s. Saudi
Arabia placed a $2bn order for helicopters and 150 T-90S MBTs in
September 2009. In the same year, Turkmenistan ordered 10 T-90S tanks
under a $30m contract.
T-90S armament
The T-90S armament includes one 125mm 2A46M smoothbore gun,
stabilised in two axes and fitted with a thermal sleeve. The gun tube
can be replaced without dismantling inside the turret. The gun can fire a
variety of ammunition including APDS (Armour Piercing Discarding
Sabot), HEAT (high-explosive anti-tank), HE-FRAG (high-explosive
fragmentation) as well as shrapnel projectiles with time fuses.
The T-90S gun can also fire the 9M119 Refleks (NATO designation AT-11
Sniper) anti-tank guided missile system. The range of the missile is
100m to 4,000m and takes 11.7 sec to reach maximum range. The system is
intended to engage tanks fitted with ERA (explosive reactive armour) as
well as low-flying air targets such as helicopters, at a range of up to
5km. The missile system fires either the 9M119 or 9M119M missiles which
have semi-automatic laser beamriding guidance and a hollow charge
warhead. Missile weight is 23.4kg. The guns automatic loader will feed
both ordnance and missiles.
Also fitted is a coaxial 7.62mm PKT machine gun and a 12.7mm air
defence machine gun. A 5.45mm AKS-74 assault rifle is carried on a
storage rack.
Self protection
The T-90 tank is protected by both conventional armour-plating and explosive reactive armour.
The T-90 is fitted with the Shtora-1 defensive aids suite which is
produced by Electronintorg of Russia. This system includes infrared
jammer, laser warning system with four laser warning receivers, grenade
discharging system which produces an aerosol screen and a computerised
control system.
It is also fitted with NBC (nuclear, biological and chemical) protection equipment.
Fire control and observation
The T-90S has the 1A4GT integrated fire control system (IFCS) which
is automatic but with manual override for the commander. The IFCS
contains the gunner's 1A43 day fire control system, gunner's TO1-KO1
thermal imaging sight which has a target identification range of 1.2km
to 1.5km and commander's PNK-S sight.
The gunner's 1A43 day FCS comprises: 1G46 day sight / rangefinder
with missile guidance channel, 2E42-4 armament stabiliser, 1V528
ballistic computer and DVE-BS wind gauge.
The commander's PNK-4S sight includes a TKN-4S (Agat-S) day / night
sight which has identification ranges of 800m (day) and 700m (night).
The driver is equipped with a TVN-5 infrared night viewer.
Propulsion
The T-90S has a liquid-cooled V-84MS 618kW (840hp) four-stroke V-12
piston engine. This engine can be fuelled by T-2 or TS-1 kerosene and
A-72 benzine, in addition to diesel. The tank can carry up to 1,600
litres of fuel in the main fuel tanks and fuel drums. The fuel tanks are
reinforced with armour plating.
The tank is provided with a snorkel for deep fording and can ford 5m
of water with equipment which can be deployed in 20 minutes.
The mechanical transmission includes primary reduction gear, two
planetary final gearboxes and two planetary final drives. The running
gear features torsion bar suspension with hydraulic shock absorbers at
one, two and six road wheel stations and tracks with rubber-metallic pin
hinges.

Although a development of the T-72, the T-90 uses a 125mm 2A46
smoothbore tank gun, 1G46 gunner sights, a new engine, and thermal
sights. Standard protective measures include a blend of regular steel
and Kontakt-5 explosive-reactive armor, laser warning receivers, Nakidka
camouflage and the Shtora infrared ATGM jamming system. The EMT-7
electromagnetic pulse (EMP) creator is used in testing but not fitted to
T-90s in active service. It is designed and built by Uralvagonzavod, in
Nizhny Tagil,
Russia.
