The characteristics of the Russian Invar 9M119M1 (Invar-M) are as follows:
· It is fired from a 125-mm smoothbore gun with increased accuracy
· It operates like a guided missile
· It weighs 17.2 kg and is 680 mm (26.7 inches) long
· It is fitted with a retractable stabiliser (across a 250 mm / 9 inch range), which helps with aiming (the missile is guided along a laser beam, controlled by the tank gunner).
· It has a maximum range of 5,000 m at a speed of 350 m/sec (the maximum speed for a flight of 14 seconds).
It has a tandem warhead, with a dual application in combat: it first penetrates armour up to 900 mm (35 inches) thick, and it then ensures detonation of the warhead.
It has to be said that India has purchased the latest modification, along with a licence to manufacture a further 15,000 missiles.
In accordance with existing agreements, India is to receive around 1,400 T-90 tanks by the end of this decade. The T-90 first entered service in 1993, and India is the largest country to use this system. India is planning to form 21 tank battalions by 2020, all equipped with the T-90 tank.
In fact there are only 45 combat ready tanks in each battalion. The other 17 are either in reserve or intended for training purposes.
