An anti-radiation missile (ARM) is a missile designed to detect and home in on an enemy radio emission source.Typically, these are designed for use against an enemy radar, although jammers and even radios used for communications can also be targeted in this manner.
Most ARM designs to date have been intended for use against ground-based radars. Commonly carried by specialist aircraft in the Suppression of Enemy Air Defenses (SEAD) role. The primary purpose of this type of missile is to degrade enemy air defenses in the first period of a conflict in order to increase the chances of survival for the following waves of strike aircraft. They can also be used to quickly shut down unexpected surface-to-air missile (SAM) sites during an air raid. Often, SEAD escort aircraft also carry cluster bombs, which can be used to ensure that, after the ARM disables the SAM system’s radar, the command post, missile launchers, and other components or equipment are also destroyed to guarantee that the SAM site stays down.
After the success of Agni-V project, DRDO is developing an Anti-Radiation Missile which can hugely multiply the strike capabilities by destroying the enemy’s advance warning system.
The future battle is very tough with modern capabilities, the one who controls the space eventually wins the war. Almost all nations military’s have mobile radar battery and air defense missiles to counter incoming air targets like helicopters and fighter jets. Radar’s are the only option to scan the sky for any intruders in long range.
After the development of this missile, India will enter the elite club of countries who has such missiles. Presently a few countries like USA, Russia, Israel, Germany, China & Brazil have such missiles.This missile is being developed by Defence Research & Development Lab (DRDL) based in Hyderabad.
It will be an Air-to-Surface missile (ASM) with a range of 100 to 125 km.This missile will be mounted on advanced air superiority fighter Su-30MKI and indigenously developed LCA Tejas.This missile is completely indigenous including its radiation seeker.
The shape and other features of the anti-radiation missile will be similar to Astra missile but its size may be larger than Astra.Instead of thrust propulsion, Indian Anti-radiation missile uses dual pulse propulsion system as in the case of LR-SAM. The dual pulse propulsion will widen the envelope as well as the engagement capability of the missile.
The missile uses the exact dual pulse motor used in the Barak 8 missile, The missile have two stages, when launched from the air craft the first engine ignites and go through the designated way point, once the missile’s seeker found the target and locks himself, it uses the second high speed motor in the terminal phase.
‘’Development of the missile has been completed. It is being integrated with the launching platform. If everything goes as per plan, the maiden test of the weapon system would be carried out in November,’’ said a defence official.The state-of-the-art high speed missile will be first-of-its-kind in the country’s arsenal. It will pick up signals or radiation emitted from the radars or tracking networks from a certain distance and destroy the communication systems leaving the enemies completely shattered.
’In fact, radars, tracking apparatuses and other communication facilities of enemies are the first targets during wars. A sensor on the tip of NGARM will pick up radio frequencies and destroy those systems. The system will give a boost to the armed forces,’’ the official said.
Defence sources said the new tactical missile is a single-stage liquid-propelled system. It can use dual propulsion depending on the requirement. After developmental trials, it will be integrated with front line fighter aircraft Sukhoi and multi-role light combat aircraft Tejas.
The ground test will validate its seeker, structural integrity, navigation and control system besides its aerodynamic capabilities. Developed by DRDO, NGARM weighs around 140 kg. It can also be mounted on Jaguar and Mirage class fighter aircraft.
Earlier, the Indian Air Force (IAF) had raised objection over weight of the missile stating that weapon systems over 100 kg would be too bulky and it requires missile weighing less than 100 kg. The DRDO, however, claimed that the new missile will fit into both the fighter aircraft which will add teeth to their fire power.
Indian air force too have some anti radiation missiles like Russian supplied Kh 35 anti radiation variant used in Su 30 MKI, and the French supplied Martel missile used in Jaguar and Mirage 2000. India also placed an order to buy some hundreds of American AGM 88 to be used in Jaguar.
There is another one similar like anti radiation missile, named K 100 novatar developed by Russia and India jointly, To destroy airborne control center AEWCS planes like Saab Erieye and E 3. India and Russia using this since years which will be carried by Su 30 MKI.
The DRDO have pretty good lessons, studied from the Astra missile and the Barak 8 missile, Here the NG ARM comes with both Astra and Barak 8 technologies, The missiles shape and other characteristics are almost identical to the Astra, however it’s believed that the missile must be over sized,
Anti radiation missiles uses a variety of radar warning receiver coupled with a DRFM- Digital radio frequency memory. the miniaturized re designed above system to be used as a seeker in the Missile, who can scan radar frequency’s and guide themselves to approach the target. Similar like other anti radiation missiles.
