AGNI-2 MRBM (Medium 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-2 MRBM (Medium Range Ballistic Missile),Indian Armed Forces

The Agni-II is a Medium Range Ballistic Missile being developed by Defence Research and development Organisation (DRDO) India.

The Agni-II borrows heavily from the original program, though it uses a two-stage solid propellant motor instead of the two-stage solid/liquid propellant motor employed by its predecessor. The range of the missile would allow India to attack all of Pakistan and parts of China.

Agni-II is the medium range,rail/road-mobile with two solid fuel stages and a Post Boost Vehicle (PBV) integrated into the missile’s Re-entry vehicle (RV).The Agni’s manoeuvring RV is made of a carbon-carbon composite material that is light and able to sustain high thermal stresses of re-entry, in a variety of trajectories.


Development and Testing

Development on the missile began in July 1997 after the original Agni (technical demonstrator) missile program was cancelled in 1996.Different optimisations and ruggedisation were done to old 1980 vintage design,Re-entry vehicles and avionics were brought up,Pokhran-II nuclear family designed was discussed and reviewed then a decision finalised to make a high yield weapon configuration having payload of 500 kg including weapon and RV.However the basic design that was earlier developed continued to be used,keeping the future open for more optimised missile design and lighter Payload.

The Agni-2 underwent its first flight test in April 1999 from Wheeler’s Island in the Bay of Bengal. The test was conducted from a rail-car TEL. In 2001, the Agni-2 was tested from a road TEL. A third test, from a rail-car TEL, was made in August 2004. On 17 May 2010, the missile was flight-tested successfully from Wheeler Island off the Orissa coast. The flight lasted 660 seconds, with the missile achieving its full range, after which it splashed into the sea at the predesignated target.

Last Successful test was carried out at 7 April 2013 where Indian test fired Agni-II ballistic missile with range of more than 2000 km, from Wheeler Island, Odisha at 10:20 AM. The test was carried out by the Strategic Forces Command of the Indian Army as part of training exercise with logistic support provided by the DRDO.

By the end of 2001, less than five Agni-2 missiles were operational, but their production rate from 2001-present is expected to be around 10 missiles per year. The missiles are operated by the 335 Missile Group at Secunderabad using 12 TEL vehicles.agni2-4

Features and Capabilities

The Agni-II missile is 21 m long and 1.3 m in diameter.The missile has a launch weight of 16,000 kg.It is capable of carrying 1000 kg overall payload,a 250 kg RV with a 750 kg warhead,Strategic nuclear (15kt to 250 kt) conventional HE-unitary,penetration,Sub-munitions,incendiary or fuel air explosives.

Propulsion and Performance

The Agni-II is propelled by Two and Half Stage Solid Propellant engine.The First Stage uses solid fuel propellant and the Second stage also uses solid fuel propellent and it weighs around 4,200 kg.This stage has flex nozzles for thrust vectoring,enabling precise trajectory control.

The Last half stage covers the RV part.The missile integrated with RV and range is highly influenced by use or non-use of thrusters on the RV for propulsion as a HAM(High Altitude Motor).There is room in the RV for about 200 kg fuel (solid or liquid) after allowing for a long but lightweight thermonuclear weapon.This RV integrated HAM is referred to as the half stage after the two solid fuelled stages. This stage provides a disproportional increase in range for a lighter RV payload.

The Agni-II has a range of 2000-3000km with the flight altitude of 230 km and flight ceiling of 405 km.It can hit the target at the speed of Mach 12 (3.9 km/sec) with the accuracy of 30-40 m(as in Latest version).The range of Agni-II is significantly greater than needed to strike targets within all of Pakistan,but its range falls short of primary targets within China.agni2-3

Mobility and Guidance/Navigation System

The Agni-II is designed to be launched from 8×8 Tatra Transporter-Erector-Launcher (TEL) vehicles, either road or rail-mobile. This mobility will allow India to position and fire the Agni-1 during rapidly changing military situations.

In addition Agni-II has impressive accuracy especially at close range due to its new concept in missile control system by adopting MIL-STD-1553 databus for all on-board communication and control device interconnection mainly INS system, Flight Control Computer, actuators and sensors.All the software in the Agni-II has been designed around this bus.This reduces the number of connections and also makes the missile more rugged.
