After the success of Agni-V project India is developing an Anti-Radiation Missile (ARM) which can hugely multiply the strike capabilities by destroying the enemy's advance warning system. Production of the ARM, which are among the most advanced missiles, is being undertaken on priority basis by the Defence Research and Development Laboratory (DRDL), which specialises in the missile development. Such missiles can be mounted on Sukhoi fighter planes Su-30 MKI, 140 of which have already been acquired by India from Russia and around 100 more are expected to be delivered in due course of time. These missile can detect a radar by tracking its electro-magnetic radiation and pulses generated, an official told PTI, adding these would be independent of the radar wavelength and be able to destroy it. Such missiles currently in use of some major powers like the US, can detect and attack a radar antenna or transmitter with minimal aircrew input. The proportional guidance system that homes in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose. The Anti Radiation Missiles in use by the US Air Force move at the speed of over Mach 2, propelled by a smokeless and solid propellant rocket motor.
The US Air Force introduced High Speed Anti-Radiation Missiles (HARM) on the F-4G Wild Weasel and later on specialised F-16s equipped with the HARM Targeting System (HTS).
