Most of the army equipment is imported, but efforts are being made to manufacture indigenous equipment. The Defence Research and Development Organisation has developed a range of weapons for the Indian Army, including small arms, artillery, radars, and the Arjun tank. All Indian military small-arms are manufactured under the umbrella administration of the Ordnance Factories Board, with principal firearm manufacturing facilities in Ichhapore, Cossipore, Kanpur, Jabalpur, and Tiruchirapalli. The Indian Small Arms System (INSAS) rifle, which has been successfully deployed since 1997, is a product of Rifle Factory Ishapore, while ammunition is manufactured at Khadki, and possibly at Bolangir.
