The Defence Research and Development Organization (DRDO) has developed Advanced Chaff Technology to protect Indian Air Force fighter aircraft from hostile radar threats. The technology was supplied to the industry for large-scale manufacture in order to satisfy the Indian Air Force’s yearly rolling need. The Defence Minister praised the DRDO, the Indian Air Force, and the industry for developing this vital technology in-house, calling it “another stride” by the DRDO toward “AatmaNirbhar Bharat” in strategic defence technologies.

What is Chaff Technology?

Chaff is an electronic countermeasure technique employed by militaries throughout the globe to defend naval ships, aircraft, and other sensitive targets from enemy missile guidance systems such as radar and radio frequency (RF). Chaff is made up of a lot of tiny aluminium or zinc coated fibres that are kept in tubes onboard the plane. Chaff is thrown into the turbulent wake of air behind the jet if the plane feels endangered by any radar tracking missiles. The chaff used in the air reflects as numerous targets for missile guidance systems, fooling enemy radars and deflecting hostile missiles.¬† The goal is to mislead anti-aircraft missiles that are either radar-guided or infrared-guided, allowing them to be redirected. The significance of this technique stems from the fact that a little amount of chaff material released in the air works as a decoy to divert hostile missiles, assuring the fighter aircraft’s safety.
