The Agni missile (Sanskrit: अग्नि, Agnī, "fire" and also the Hindu god of fire) is a family of medium to intercontinental range ballistic missiles developed by India, named after one of the five elements of nature. Agni Missiles are long range, nuclear weapons capable surface to surface ballistic missile. The first missile of the series, Agni-I was developed under the Integrated Guided Missile Development Program and tested in 1991. After its success, Agni missile program was separated from the IGMDP upon realizing its strategic importance. It was designated as a special program in India's defence budget and provided adequate funds for subsequent development. As of 2008, the Agni missile family comprises three deployed variants while two more variants are under testing:[17]

Agni-I[]
The two-stage Agni technology demonstrator, with a solid-fuel first stage, was first tested at the Interim Test Range in Chandipur in 1989. It was capable of carrying a conventional payload of 1,000 kg (2,200 lb) or a nuclear warhead. This original technology demonstrator evolved into the solid-fuel Agni-1 and Agni-2 missiles. India first developed the two-stage 2000 km range Agni-2, testing it in 1999. It then used the first stage of this system to develop the 700 km range single-stage Agni-1, which was first tested in January 2002.
Weighing 12 tonne with a length of 15 metres, Agni-1 has a range of 700–1250 km[9][18] and is capable of carrying a conventional payload of 1,000 kg (2,200 lb) or a nuclear warhead[2] at a speed of 2.5 km/s.[4] Agni missiles consist of one (short range) or two stages (intermediate range). These are rail and road mobile and powered by solid propellants. Agni-I is used by the Strategic Force Command (SFC) of the Indian Army.[2] On 13 July 2012, India test fired Agni I successfully at Wheeler Island off Orissa coast.[27]
Agni-II[]

Agni-II with a range of 2,000–2,500 km is 20 metres long, has a diameter of one metre, and weighs around 18 tonnes. Agni – II uses solid propellant in both of its two stages.[28] They are claimed to be a part of the "credible deterrence" against China and Pakistan. India stated that its nuclear and missile development programmes are not Pakistan-centric, that the Pakistani threat is only a marginal factor in New Delhi's security calculus, and that Agni is at the heart of deterrence in the larger context of Sino-Indian equation.[29] The Strategic Forces Command, as a part of user trials, is to launch Agni-II on 9 August 2012 from the Wheeler Islands off the Orissa coast, after it successfully launched Agni-I missile on 13 July 2012.[30] The 2000 km range nuclear weapon capable missile, already inducted into country's arsenal, was successfully launched as a training exercise by the armed forces on 9 August 2012.[31] India on 7 April 2013 test-fired its nuclear capable Agni-II strategic ballistic missile from a military base in Odisha. The test was conducted from Wheeler's Island in Bhadrak district, around 200 km from here, by army personnel as part of a training exercise. The medium-range surface-to-surface missile with a range of over 2,000 km has already been inducted into the army and is part of the Strategic Forces arsenal for nuclear deterrence.[32]
Agni-III[]
Agni-III is the third in the Agni series of missiles. Agni III uses solid propellant in both stages.[28] Agni-III was tested on 9 July 2006 from Wheeler Island off the coast of the eastern state of Orissa. After the launch, it was reported that the second stage of the rocket did not separate and the missile had fallen well short of its target. Agni-III was again tested on 12 April 2007, this time successfully, again from Wheeler Island. On 7 May 2008 India again successfully test fired this missile. This was the third consecutive test; it validated the missile's operational readiness while extending the reach of India's nuclear deterrent to most high-value targets of the nation's most likely adversaries. Agni-III has a range of 3,500 km,[8] and can take a warhead of 1.5 tonnes.[33]
It has been reported that the missile's circular error probable (CEP) lies in the range of 40 meters, This would make the Agni-III[34] most accurate strategic ballistic missiles of its range class in the world.[33] This is of special significance because a highly accurate ballistic missile increases the "kill efficiency" of the weapon; it allows Indian weapons designers to use smaller yield nuclear warheads (200 kiloton thermonuclear or boosted fission) while increasing the lethality of the strike. This permits India to deploy a much larger nuclear force using less fissile/fusion material (plutonium/lithium deuteride) than other nuclear powers. Older ballistic missiles, such as those deployed by earlier nuclear powers required larger yield (1–2 megaton) warheads to achieve the same level of lethality. It has also been reported that with smaller payloads, the Agni-III can hit strategic targets well beyond 3,500 km.
Agni-IV[]
Agni-IV is the fourth in the Agni series of missiles which was earlier known as Agni II prime.[35] Agni-IV was tested on 15 November 2011 from Wheeler Island off the coast of the eastern state of Orissa.The missile was successfully test-fired again on 19 September 2012 for its full range of 4,000 km from the Wheeler Island, off the Orissa coast. The missile lifted off from a road mobile launcher at 11.48 a.m. and after zooming to an altitude of over 800 km, it re-entered the atmosphere and impacted near the pre-designated target in the Indian Ocean with remarkable degree of accuracy following a 20-minute flight. Carrying a payload of explosives weighing a tonne, the missile re-entered the atmosphere and withstood searing temperatures of more than 3,000 °C. With a range of 3,000–4,000 km[21][36] Agni-IV bridges the gap between Agni II and Agni III. Agni IV can take a warhead of 1 tonne. It is designed to increase the kill efficiency along with a higher range performance. Agni IV is equipped with state-of-the-art technologies, that includes indigenously developed ring laser gyro and composite rocket motor. It is a two-stage missile powered by solid propellant. Its length is 20 meters and launch weight 17 tonnes.[35] It can be fired from a road mobile launcher.[35][37][38]
Agni-V[]
Agni-V is a solid fueled intercontinental ballistic missile (ICBM) developed by Defence Research and Development Organisation (DRDO) of India. It will greatly expand India's reach to strike targets more than 5,000 km away. Agni-V was test fired successfully on 19 April 2012 at 08:07 am IST from Wheeler Island off the coast of Orissa.[39][40] Agni-V ICBM has been designed with the addition of a third composite stage to the two-stage Agni-III missile.[4] To reduce the weight it is built with high composite content. The 17.5-metre-long Agni-V would be a canister launch missile system so as to ensure that it has the requisite operational flexibility and can be swiftly transported and fired from anywhere.[4] Agni-V weighs around 49 tonnes; one tonne more than Agni III and a much longer range.[4] Canister launched version of Agni 5 to be tested sometime in July 2013. The second test launch of Agni-V was successfully done on 15 September 2013 at 08:43 am IST from Wheeler Island off the Orissa coast.
Agni-VI[]
Agni-VI is an intercontinental ballistic missile reported to be in early stages of development by India. It is to be the latest and most advanced version among the Agni (missile) program. It will be capable of being launched from submarines as well as from land, and will have a strike-range of 8,000–10,000 km with MIRVed warheads.[6][25][26]
Further developments[]
In May 2008 Indian scientists announced they had developed and patented a path-breaking technology that increases the range of missiles and satellite launch vehicles by at least 40%.[41] The enhanced range is made possible by adding a special-purpose coating of chromium-based material to a rocket's blunt nose cone. The material acts as a reactive-ablative coating that forms a thin low density gaseous layer at the tip of the rocket as it approaches hypersonic speeds; this super-heated gas layer reduces drag by 47% (at mach 7–8), thereby allowing range enhancements at least 40%.[42][43] It has been announced that this technology will be incorporated in future Agni deployments after having undergone ranging and calibration tests.
