Range comparison of Agni missiles

Agni-IV is the fourth in the Agni series of missiles which was earlier known as Agni II prime. It has been developed by India's DRDO and displayed a number of new technologies and significant improvement in missile technology. The missile is light-weight and has two stages of solid propulsion and a payload with re-entry heat shield.[4]

Development[edit]

The DRDO had produced and proven many new state of the art technologies with the Agni-IV like composite rocket motors, very high accuracy Ring Laser Gyro based Inertial Navigation System, Micro Navigation System, Digital Controller System and very powerful onboard computer system.[4] 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. Its a two-stage missile powered by solid propellant. Its length is 20 meters and launch weight 17 tonnes. It can be fired from a road mobile launcher.[5][6] Efforts are being made to fine-tuning the Agni missiles to defeat anti-ballistic missile systems. Radar and other signatures of Agni-IV have been significantly reduced to make them much more immune to counter-measures.[7]

Testing[edit]

  • 15 November 2011: Agni-IV was successfully test fired for the first time, from a road mobile launcher at 9AM from Wheeler Island off the coast of Orissa. The missile followed its trajectory, attained a height of about 900 km and reached the pre-designated target in international waters of the Bay of Bengal. All mission objectives were fully met. All systems functioned perfectly till the end encountering re-entry temperatures of more than 3000⁰C.[4]
  • 19 September 2012: The missile was successfully test-fired again for its full range of 4,000 km from the Wheeler Island, off the Orissa coast.[8] 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.[2][9]
  • 20 January 2014: The missile was test-fired in the actual weapon and road-mobile configuration of the Strategic Forces Command (SFC), from the launch complex-4 of the Integrated Test Range at Wheeler Island off Orissa coast. The missile traveled a vertical distance of 850 km and covered its full range of 4,000 km. The on board ring laser gyro-based inertial navigation system (RINS) and the micro-navigation system (MINGS) enabled the missile to fall within 100 meters of its target. The re-entry shield withstood outside temperatures as high as 4,000°C, enabling the avionics to work at less than 50°C inside. The missile's production line will start by end of 2014 or early 2015 and its induction into the SFC will happen simultaneously.[10][11]
