Explanation:

Captive flight trials of an advanced, state-of-the-art

Anti-Radiation Missile (ARM) are planned for April-May this

year, and the maiden flight test by year-end by the missile

technologists of the Defence Research and Development

Organisation.

The air-to-surface tactical missile being developed by

Defence Research and Development Laboratory (DRDL) will

target the enemy’s air defense capabilities by attacking radars

and communication facilities. The range of the missile is 100 to

125 km and it will be mounted on combat aircraft Sukhoi (Su30) and Tejas-Light Combat Aircraft. The missile picks up the

radiation or signals of radars and communication facilities and

homes on to the targets to destroy them.

According to DRDO sources, scientists will evaluate the

performance of the seeker, navigation and control system,

structural capability and aerodynamic vibrations during the

captive flight trials. These will be followed by ground testing

and the missile will be fired from Su-30 during the actual flight

trial by year-end. Instead of thrust propulsion, the 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. After coasting the missile

for the required duration by firing the first pulse, the second

pulse will be initiated just before interception of the target or

during the terminal phase, the sources added.

The entire missile is being developed indigenously,

including the seeker. The missile will be inducted in about two

years after conducting a number of developmental trials. Only

a few countries, including the U.S. and Germany, have ARMs at

present, the sources added. The dual pulse propulsion system

could be configured with other air-to-surface and air-to-air

missiles, the sources added.

Meanwhile, the induction of LR-SAM (Long Range

Surface-to-Air Missile), jointly developed by India and Israel,

will begin September-October this year. It was successfully testfired from INS Kolkata to intercept an aerial target last year and

the missile is slated to be launched from warships, INS Kochi

and INS Chennai, for similar trials later this year.
