DRDO successfully flight tests Indigenously Developed Anti Radiation Missile (RUDRAM)

      WHY IN NEWS:

New generation Anti Radiation Missile (RUDRAM) was successfully Flight tested.The missile was launched from SU-30 MKI fighter aircraft.

MINISTRY? :- Ministry of Defence


For PRELIMS go through every specification , take a note of passive home head .

For MAINS nothing much here .


India’s first indigenous anti-radiation missile, Rudram, was successfully flight-tested from a Sukhoi-30 MKI jet off the east coast .


  • The Sanskrit name Rudram was given in keeping with tradition, because it includes the letters ARM (the acronym for anti-radiation missile).
  • The word in Sanskrit describes a “remover of sorrows” (one of its meanings).


  • Rudram is an air-to-surface missile.

It is designed and developed by the Defence Research and Development Organisation (DRDO).

  • Officials said DRDO initiated development of anti-radiation missiles of this type around eight years ago.
  • Its integration with fighter jets has been a collaborative effort of various DRDO facilities and formations of the IAF and Hindustan Aeronautics Ltd.
  • While the system has been tested from a Sukhoi-30 MKI, it can be adapted for launch from other fighter jets too.


Anti-radiation missiles are designed to detect, track and neutralise the adversary’s radar, communication assets and other radio frequency sources.

Such a missile’s navigation mechanism comprises:

  • An inertial navigation system
  • A computerised mechanism that uses changes in the object’s own position
  • The missile is coupled with GPS, which is satellite-based.


  • The RUDRAM is first indigenous anti-radiation missile of the country for Indian Air Force (IAF).
  • The missile is integrated on SU-30 MKI fighter aircraft as the launch platform, having capability of varying ranges based on launch conditions.

It has INS-GPS navigation with Passive Homing Head for the final attack.

  • The RUDRAM hit the radiation target with pin-point accuracy.
  • The Passive Homing Head can detect, classify and engage targets over a wide band of frequencies as programmed.
  • The missile is a potent weapon for IAF for Suppression of Enemy Air Defence effectively from large stand-off ranges.


For guidance, it has a “passive homing head” — a system that can detect, classify and engage targets (radio frequency sources) .

  • The missile can be programmed over a wide band of frequencies .
  • Rudram missile locks on the target, it is capable of striking accurately even if the radiation source switches off in between.


The missile can be launched from altitudes of 500 m to 15 km and speeds of 0.6 to 2 Mach.

  • It hit the radiation target with pinpoint accuracy.
  • The missile has an operational range of more than 100 km, based on the launch parameters from the fighter jet.


  • Rudram has been developed for the IAF’s requirement to enhance its Suppression of Enemy Air Defence (SEAD) capability.
  • 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.

This will in turn  lead to higher survivability to a country’s own aircraft.

  • Neutralising or disrupting the operations of the adversary’s early warning radars, command and control systems.
  • Using SEAD , surveillance systems can be blocked that use radio frequencies and give inputs for anti-aircraft weaponry, can be very crucial.

      IASbhai WINDUP: 

  • Because the missiles are to be carried and launched from extremely complex and sensitive fighter jets, the development was full of challenges.
  • Such as development of radiation seeker technologies and guidance systems, besides integration with the fighter jet, said a DRDO scientist.
  • Scientists said modern-day warfare is more and more network-centric.
  • It means it comprises elaborate detection, surveillance and communication systems that are integrated with the weapons systems.
