In News

The Defence Research and Development Organisation (DRDO) has developed three variants of a ‘Chaff Rocket’.

About

• The DRDO’s facility Defence Laboratory Jodhpur (DLJ) has indigenously developed three variants of this critical technology:
  • Short Range Chaff Rocket (SRCR)
  • Medium-Range Chaff Rocket (MRCR) and
  • Long Range Chaff Rocket (LRCR).
• The chaff system basically comprises multiple barrel launchers (Port and Starboard configuration), with each launcher possessing a built-in stabilization system against roll, pitch and yaw motions.
