Agni-IV

This missile is one of a kind, proving many new technologies for the first time, and represents a significant leap in India's missile technology. The missile is lighter in weight and uses a two-stage rocket engine powered by solid propellant. The Composite Rocket Motor which has been used for the first time has given excellent performance. The missile system is equipped with modern and compact avionics with redundancy to provide a high level of reliability. The indigenous-built ring laser gyroscope is used in the high accuracy with Micro Inertial Navigation System (MINGS), which complement each other as a redundancy. Efforts are being made to fine-tune the Agni missiles to defeat anti-ballistic missile systems. The radar cross-section and other detectable signatures of Agni-IV have been significantly reduced to make them much more immune to counter-measures. ==Testing==

Agni-IV has undergone seven successful tests over the course of six years. • 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 . The missile lifted off from a road mobile launcher at 11:48a.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 . • 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 onboard 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 , enabling the avionics to work at less than inside. • 2 December 2014: The missile was successfully test-fired by the Strategic Forces Command (SFC). This was the first user trial and fourth consecutive successful flight. The missile has been inducted into the Indian Army. • 9 November 2015: Agni IV was successfully test-fired as part of a user trial by the tri-Service Strategic Forces Command (SFC). According to DRDO officials, the missile met all mission parameters. • 2 January 2017: Agni IV was successfully test-fired as part of a user trial by the Strategic Forces Command (SFC) at 11:55am from launch complex-4 of the Integrated Test Range (ITR) at Wheeler Island. According to DRDO officials, the user trial met all mission objectives. • 23 December 2018: The Agni IV was successfully test fired from Launch Complex-4 of the Integrated Test Range (ITR) at Abdul Kalam Island at around 8:35am. • 6 June 2022: A successful training launch of an Intermediate-Range Ballistic Missile Agni-IV was carried out at approximately 19.30 pm hours on 6 June from APJ Abdul Kalam Island, Odisha. • 6 September 2024: Successful launch was carried out from the Integrated Test Range in Chandipur, Odisha. The test was conducted by Strategic Forces Command. ==See also==
