Ajit Kumar AJIT KUMARWISDOM IAS, New Delhi.

India successfully test-fired its nuclear-capable strategic ballistic missile. Agni-IV with a strike range of 4000 km as part of a user trial from a test range off Odisha coast on January 2, 2017. The surface-to-surface missile was flight tested from launch complex-4 of the Integrated Test Range (ITR) at Dr Abdul Kalam Island, formerly known as Wheeler Island, at about 11.50 AM, supported by a mobile launcher.
   
While Strategic Forces Command (SFC) of the Indian Army conducted the test, DRDO provided all logistic supports. This was sixth test and third user trial of the missile which is best in its class in the world.

Defence sources said the missile took off majestically, rose to a height of over 850 km, covered the intended range and hit the target with two digit accuracy, meeting all mission objectives and proving the capabilities of the missile.

The successful trial of Agni-IV came close on the heels of a similar test of the long-range missile Agni-V carried out from the same test range on December 26, 2016.

The Agni-IV missile propelled by composite solid fuel rocket motor technology was launched from its road mobile launcher indigenously developed by Defence Research and Development Organisation in the presence of Union minister of state for defence Subhash Ramrao Bhamre and Scientific adviser to defence minister and director-general of Missiles and Strategic Systems G Satheesh Reddy.

The mission met all objectives as monitored and confirmed by the telemetry, electro-optical stations, radar stations along the coast. Down range ships positioned at the target point monitored the terminal event. The test was of greater significance as the system was tested in its deliverable configuration.
The missile was first tested as Agni-II prime on December 10, 2010 which had failed. As Agni-IV it was first tested on November 15, 2011 while it’s second, third, fourth and fifth tests on November 15, 2011, September 19, 2012, January 20 and December 2, 2014 and November 9, last year were successful.
The two-stage sleek missile is 20 meter-long and weighs around 17 tonnes. The successful test paves a way for its serial production.

8. Agni-IV weighs less compared to its younger sibling Agni-III which has a strike range of around 3,000-km. While Agni-III is about 46 tonnes, Agni-IV is only 17 tonne.

9. Agni-IV is designed is a different manner to increase the kill efficiency along with a higher range of performance.

10. The missile can be fired from locations deeper in the Indian hinterland, which will be very difficult for the enemy to track and destroy the missile. It possesses a submarine launch capability. It would be virtually indestructible and unstoppable in times of war.

Successful launch of the missile reflected the nations’ capabilities in design, development leading to production, contemporary weapons and platforms for strengthening its deterrence and defence capabilities.

                                                         Agni Missile Series

Agni-I

Agni-I is the first story that made India an innovative country as far as missile technology is concerned it was developed by the India's pride organization Defiance Research Development
Organization(DRDO) .

Agni-I was first test fired successfully at India's famous Integrated Test Range in Chandipur situated in Odissa state on 25 January 2002.It is 12 tone in weight,15 meters in length. Agni-I is capable to cover the range of 700-1200 km and at the same time it is capable of carrying a conventional payload of 1,000 kg (2,200 lb) or a nuclear warhead at a speed of 2.5 km/s.

Agni series missiles consist of one stage in the short range while two stages in the intermediate range. The most important aspect of the Agni series is that it can fired from rail and road mobile and powered by solid propellants. Agni-I is under use by the Strategic Force Command (SFC) of the Indian Army.

Agni-II ballistic missile

Agni-II is an another deadliest weapon in Indian basket capable to cover the range of 2,000-2,500 km its length is 20 meters, with the diameter of one meter, while its weight is little more than Agni -I of around 18 tones.

Agni - II build upon solid propellant in both of its stages. They are said to be a part of the "credible deterrence" against China and Pakistan by India. India always claims that its nuclear and missile development programmers are not Pakistan-centric, that the Pakistani threat is only a marginal factor in India's security calculations, and that Agni series is at the core of country's deterrence in the larger context of Sino-Indian power equation.

Agni-III

Agni-III is the third weapon in the Agni series of missiles developed by the Defiance Research Development Organization (DRDO) . Agni III based upon the powerful solid propellant in its both stages.

Agni-III was first testfired on July 9, 2006 from Wheeler Island off the coast of the eastern state of India, Ordissa. After the unsuccessful launch, it was found by the DRDO scientists that the second stage of the rocket did not separated from the body and the missile had fallen well short of its pre determined target.

Agni-III was again tested after ratifying the technical glitch on April 12, 2007, and this time it was successfully hit the target , again from Wheeler Island close to Orissa cost. On May 7, 2008 India again tested it successfully. This was the third consecutive test it confirmed the Agni-III's'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 capability to cover the range of 3,500 km and can have a warhead of 1.5 tonnes. It has been claimed that the missile's circular error probable (CEP) lies within of 40 meters only, this makes Agni-III most accurate and deadliest strategic ballistic missiles of its range class in the world.
The CEP of Agni-III IS of special significance for the Indian Scientists because a highly accurate ballistic missile increases the "kill efficiency" of the weapon; it also allows Indian weapons scientists to use smaller yield nuclear warheads (200 kiloton thermonuclear or boosted fission) while increasing the lethality of its strike.

This allows country to deploy a much powerful nuclear warhead using less fissile/fusion material (plutonium/lithium deuteride) than other nuclear material.

Older ballistic missiles deployed by other nuclear power countries needs 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 this makes this missile ultra dangerous for enemy.

Agni-IV

Agni -IV is made for increase the kill efficiency along with a higher range performance matrix. Agni IV is loaded with state-of-the-art technologies, which includes indigenously developed ring laser gyro and composite rocket motor as well. It is a two-stage missile powered by powerful solid propellant. Its length is 20 meters and launch weight is about 17 tones.More importantly It can be launched from a road mobile launcher.

Agni-V

Agni-V is a solid fueled intercontinental ballistic missile (ICBM) which is in the final stage of development under India's prime weapon research organization Defence Research and Development Organization (DRDO) of India who has the credit to develop all earlier Agni variants.

It will greatly expand countries's reach to strike goals up to 5,000 km away from the launch pad.
Missile tests are expected to begin in coming month Agni-V ICBM has been designed with the addition of a third composite stage to the two-stage successful Agni-III missile. To minimize the weight it is built with high composite content which is helpful to achieve the distance.

The 17.5-metre-long Agni-V would be a canister launch missile system so as to ensure that it has the much needed operational flexibility and can be swiftly transported and launched from anywhere as per need. Agni-V weighs around 49 tones, which one tone above than Agni III even though its range is much farther.

Agni-VI

Agni-VI is another powerful intercontinental ballistic missile said to be in its early stages of development by DRDO labs.Agni-VI is going to be the real ICBMR of India as It is going to be the latest and most advanced version among the Agni (missile) program. Agni-VI will be carable of being launched from submarines or from land; it will be able to strike at a target of 6,000-10,000 km with MIRVed warheads.

After the Success of Agni-VI India will become one of the countries which have the capability to target any spot in the world.
