RudraM : Indigenously Developed Anti-Radiation Missile

In News

  • The Defence Research and Development Organisation (DRDO )has successful tested the New Generation Anti Radiation Missile (NGRAM) also called the Rudram-1.
  • This is the first indigenous anti-radiation missile of the country.
  • The missile was launched from Sukhoi-30 MKI fighter aircraft and all mission objectives were successfully met.

About: Anti-radiation missile

  • Anti-radiation missiles are designed to detect, track and neutralise (disrupt) the enemy’s radar, communication assets and other radio frequency sources, which are generally part of their air defence systems.
  • By doing so, they clear the path for own fighters to carry out an offensive attack and also prevent own systems from being blocked.

About: Radar

  • Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft and guided missiles.
  • A radar system consists of a transmitter producing radio waves. Radio waves from the transmitter reflect off the target object and return to the receiver, giving information about the object’s location and speed.

In Focus: Rudram-1

  • The New Generation Anti Radiation Missile (NGRAM), also called the Rudram missile, is designed and developed by the DRDO.
  • The Sanskrit name Rudram is given because it includes the letters ARM (the acronym for anti-radiation missile) and the word Rudram in Sanskrit describes “remover of sorrows” (one of its meanings).


  • Rudram is an air-to-surface anti-radiation missile with a speed of Mach two (twice the speed of sound).
  • It is capable of bringing down (attacking) a wide-range of enemy radar systems, communication networks and air defence systems.
  • Its range depends on the height at which the fighter jet from which it is launched is flying. It can be launched from a height ranging from 500 metres to 15 km and can hit radiation emitting targets within a range of 250 km.
  • For guidance, the missile is equipped with a Passive Homing Head(PHH).
    • The PHH is a system that can detect, classify and engage targets (sources of radiation) over a wide band of frequencies as programmed.
  • It also has the capability to engage targets that have a shutdown capability. This means that even if the enemy shuts down the radar after the missile is launched, it will still hit the target.

Significance of Rudram missile:

  • Modern-day warfare is more and more network-centric, which means it comprises elaborate detection, surveillance (monitoring) and communication systems that are integrated with the weapons systems.
  • Disrupting the operations of the enemy’s early warning radars, command and control systems, surveillance systems that use radio frequencies can be very crucial.
  • Rudram has been developed for the IAF’s requirement to enhance its Suppression of Enemy Air Defence (SEAD) capability.
  • As one of the many aspects of SEAD tactics, anti-radiation missiles are used mainly in the initial part of air conflict to strike at the air defence assets of the enemy (and also in later parts), leading to higher survivability to a country’s own aircraft.
  • Thus, with this, India has established indigenous capability to develop long-range air-launched anti-radiation missiles for disrupting enemy radars, communication sites and other such targets.

Future Outlook

  • Some more flight tests would take place before the system is ready for induction.
  • They will be integrated with the fighter jets of the Indian Air Force (IAF).
  • While the system has been tested from a Sukhoi-30 MKI fighter jet, it will be adapted for launch from other fighter jets too.
