The defence ministry Thursday placed an order for 118 Main Battle Tanks (MBTs) Arjun Mark 1-A, which will be the most potent armoured system in the Army’s inventory. The Rs 7,523-crore contract is expected to be a major boost for the Heavy Vehicles Factory in Chennai’s Avadi, which manufactures the tanks also known as ‘Hunter Killers’. Mark 1-A is infused with 72 new features and more indigenous content from the Mark-1 variant. Designed and developed by Defence Research and Development Organisation (DRDO)’s Chennai-based Combat Vehicles Research and Development Establishment (CVRDE), the tank is equipped with a massive 120 mm rifled gun and the Kanchan armour.
