Agni-I was first tested at the Interim Test Range in Chandipur in 1989, and is capable of carrying a conventional payload of 1,000 kg (2,200 lb) or a nuclear warhead. Agni missiles consist of one (short range) or two stages (intermediate range). These are rail and road mobile and powered by solid propellants. The Agni I has a range of 700–1250 km. They are claimed to be a part of the "Minimum Credible deterrence".
