Why in News

The Defence Research and Development Organisation (DRDO) has developed an Advanced Chaff Technology to safeguard the naval ships against enemy missile attack.

Key Points

  • About the Technology:
    • Chaff is an electronic countermeasure technology used by militaries worldwide to protect naval ships or other sensitive targets from radar and radio frequency (RF) guiding mechanisms of the enemy missile.
    • The chaff rockets deployed in the air reflect as multiple targets for the missile guidance systems and deflecting adversary missiles, thus protecting their own assets.
    • DRDO has indigenously developed three variants of the critical technology namely Short Range Chaff Rocket (SRCR), Medium Range Chaff Rocket (MRCR) and Long Range Chaff Rocket (LRCR).
  • Difference between Chaff and Flares:
    • Both chaff and flares are defensive countermeasures deployed by military aircraft. The purpose is to confuse radar-guided or infrared-guided anti aircraft missiles fired so that they could be diverted.
    • Chaff is composed of many small aluminium or zinc coated fibres stored on-board the aircraft in tubes. In case the aircraft feels threatened by any radar tracking missiles, chaff is ejected into the turbulent wake of air behind the plane.
    • Flares on being fired provide an alternate strong IR (Infrared) source to heat-seeking anti-air missiles so that they are lured away from the aircraft.

Defence Research and Development Organisation

  • DRDO works under the administrative control of the Ministry of Defence.
  • It is working to establish a world class science and technology base for India and provides Defence Services decisive edge by equipping them with internationally competitive systems and solutions.
  • It was established in 1958 after combining Technical Development Establishment (TDEs) of the Indian Army and the Directorate of Technical Development & Production (DTDP) with the Defence Science Organisation (DSO).
  • It is responsible for carrying out Integrated Guided Missile Development Programme (IGMDP).
