[1] The Tank Ex MBT uses the chassis of the T-72M1 (Ajeya) and turret and weapon system of the Arjun.

It was developed in 2002 as a private venture and was intended to provide a solution for upgrading the Indian Army's ageing T-72M1 fleet.

The Tank Ex utilizes the Arjun MBT's 120 mm rifled gun firing unitary APFSDS and HESH semi combustible cartridge case ammunition.

The Tank Ex utilizes the "Kanchan" composite armour, especially over its frontal arc (turret as well as glacis), giving it protection against both Kinetic and HEAT rounds.

The Tank Ex should also have the capability to fire the Israeli LAHAT missile from its gun-barrel, like the Arjun.
