AGNI-4 IRBM (Intermediate-Range Ballistic Missile),Indian Armed Forces

The Agni series of ballistic missiles was developed under the Integrated Guided Missile Development Programme of the Defence Research and Development Organisation of India.It is a family of medium to intercontinental range Ballistic missiles named after one of the five elements of nature.

Agni missiles are long range,nuclear weapons capable surface to surface ballistic missile.The Agni missiles family consists of four deployed variants.The Agni-I,Agni-II,Agni-III and Agni-IV are in service with Indian army.Agni-V,The Fifth series of Agni missiles are under testing.A new intercontinental ballistic missile variant,the Agni-VI is under development.It is expected to give its service service to Indian Army by 2018.

India also possesses other powerful missiles like Akash,Prithvi,Nag and Trishul where all have different strike capabilities and roles but the Agni is by far the most superior set of missiles India is in possession of.

Let us discuss about the Agni missiles one by one.

AGNI-4 IRBM (Intermediate-Range Ballistic Missile),Indian Armed Forces

Agni-4 is the intermediate range Ballistic missile developed by Defence Research and Development Organisation (DRDO) of India.It is the fourth in the Agni series of missiles which was earlier known as Agni II prime.DRDO displayed a number of technologies and significant improvement in missile technology. It has the latest features to correct and guide itself through inflight disturbances.

The missile has one of its kind and has many new state of art technologies 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. The Missile, having capability to carry Strategic Warheads for the Forces, has provided a fantastic deterrence to the country.agni4-3


Agni-IV bridges the gap between Agni-II and Agni-III.It is designed to increase the kill efficiency along with higher performance.Agni-IV is quipped with state of art technologies and much reduced radar signature to make them more immune to counter-measures.Efforts are made to to fine-tuning the Agni missiles to defeat anti-ballistic missile systems.

The missile was successfully tested four times.on 15,November 2011 Agni-IV was successfully tested from a road mobile launcher from Wheeler Island off the coast of Orissa.Then After on 19 September 2012 the missile was agin tested for its full range .The missile is capable of withstanding temperature more than 3000 °C.Again on January 20 ,2014 the missile was test fired in the actual weapon and road mobile configuration of the Strategic Forces Command to check the accuracy og the missile. The re-entry shield withstood outside temperatures as high as 4,000°C, enabling the avionics to work at less than 50°C inside.

Missile was latest test fired by the Army’ Strategic Forces Command .this was the first user trail and fourth consecutive successful flight.The production has started and missile has inducted into the Indian Army.

Features and Capabilities

The Agni-IV missile is comparing to its base variant 20 m long and weighs around 17,000 kg.It is light weight missile designed with many new state of art technologies.The missile is capable of carrying 1 ton of warhead including strategic nuclear (15 kt to 250 kt) conventional,Thermobaric.


Propulsion and Performance

The Agni-IV Missile is lighter in weight and has two stages of Solid Propulsion and a Payload with Re-entry heat shield. The Composite Rocket Motor which has been used for the first time has given excellent performance. The re-entry heat shield is capable of withstanding high temperatures that may reach as high as 4000 degree centigrade and above during re-entry of missile in earth’s atmosphere and makes sure that the avionics function normally, with inside temperature remaining less than 50 degree centigrade

The Missile has the operational range of 4000 km and it may be increased by reducing the payload.The missile has the flight altitude of 900 km.The missile reach the target with the high level of accuracy.agni4-4

Mobility and Navigation/guidance system.

The missile can be fired from 8×8 TELAR (Transport erector launcher)Rail mobile launcher.

The missile is equipped with modern and compact avionics with redundancy to provide high level of reliability.The indigenous Ring Laser Gyros based high accuracy INS (RINS) and Micro Navigation System (MINGS) complementing each other in redundant mode have been successfully flown in guidance mode for the first time.It also ensure the high accuracy of missile The high performance onboard computer with distributed Avionics architecture, high speed reliable communication bus and a full Digital Control System have controlled and guided the Missile to the target.
