India’s first indigenous anti-radiation missile

The Indian Defense Ministry unveiled its most advanced military defense munition last year, the “Rudram,” which is slated to be inducted into service sometime this year.

RUDRAM (meaning “remover of sorrows”) is India’s first anti-radiation missile (ARM) developed by its Defense Research and Development Organization (DRDO) to bolster its air defense and boost the capability of its Air Force.

Like any other ARM, Rudram primarily protects India’s air space by detecting, monitoring, and neutralizing (featuring a warhead called a “passive homing head (PHH)”) its adversary’s radar, communication, and other radio frequency source. It depends on a navigation mechanism consisting of a satellite-based GPS and a computerized inertial navigation system (INS). This PHH can detect radio frequency emission as far as 100 km away and has a wide-band receiver system operating with D band to J band frequency of the electromagnetic spectrum.

It’s an air-to-surface ARM that can be launched from a range of altitudes with a significant standoff distance—approximately 250 km, flight altitude of 500 m to 15 km, and a top speed of Mach 2. During its earlier development and testing stages, RUDRAM-1 has primarily tested using Russia’s Sukhoi Su-30MKI platform but is otherwise compatible with aircrafts such as the Dassault Mirage 2000, SEPECAT Jaguar, HAL Tejas, and HAL Tejas Mark 2/MWF.
