GS Paper - 3 Defence Technology

The Defence Research and Development Organisation (DRDO) has developed three variants of a ‘chaff rocket’ for the protection of naval ships from guided-missile attacks. Chaff rocket is primarily a mechanism that when fired acts as a decoy to deflect the guiding mechanism of enemy missiles. The Ministry of Defence on 5 April 2021 said the DRDO’s facility Defence Laboratory Jodhpur (DLJ) has indigenously developed three variants of this critical technology.

What

  1. The names of this critical technology are Short Range Chaff Rocket (SRCR), Medium Range Chaff Rocket (MRCR) and Long Range Chaff Rocket (LRCR), meeting the Navy’s qualitative requirements.
  2. The Navy recently conducted trials of all three variants from a warship deployed in Arabian Sea and found the performance satisfactory.
  3. 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.
  4. 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.
  5. The DRDO has gained expertise to meet futuristic threats from adversaries. The technology is being given to the industry for production in large quantities.
