T-90s The Bhishma,Main Battle Tank,Combat Indian Army 

The T-90 is a Russian third generation main battle tank.It is the latesr 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.

Orginally derived from Russia,Bhishma is a dubbed name just for T-90S.Russian Ministry of Defence found that it could no longer afford to manufacture two war tanks in parallel.The one bein T-80U which was of better quality and other was the chepaer one T-72B.Therfore they started giving small orders along with improvised features for improving exportation to other countries.

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.Currently India operates more than 862 T-90S which were produced in three separate orders.

Finally India got the licence to manufacture the T-90S. Russia supplied documents for the local manufacture of the tank in India. A T-90S Bhishma tank was thus manufactured by the Heavy Vehicles Factory at Avadi, Tamil Nadu on January 7, 2004. Following which 10 others were manufactured by the end of 2009.Further 1000 tanks were supposed to be produced locally by 2020. The sole purpose of purchasing T-90S was that it had features almost similar to the T-72 which were then used by Indian Army there by simplifying training and maintenance.

T-90S tank is 9.63m long ,3.73 m wide and 2.22 m high.It weighs around 46 tonnes.The tank is fed by automatic loader which removes the need for a manual loader in the tank and reduces the crew to 3 which includes commander,gunner and driver.

T-90S Bhessma Armaments

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 APFSDS (Armour Piercing Fin-Stabilised 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.
