Recently DRDO developed an Advanced Chaff Technology to safeguard naval ships against missile attacks. One of the DRDO laboratories located in Jodhpur developed the 3-variants of the Advanced Chaff Technology. They were Short Range Chaff Rocket, Long Range Chaff Rocket and Medium Range Chaff Rocket.

Key Features

  • The Advanced Chaff technology is used in Naval ships worldwide to self-defend against enemy radar and radio frequency missile seekers.
  • The most significant fact of the Advance Chaff Technology developed by Defence Research and Development Organisation is that it uses very less chaff material to deflect enemy missiles.
  • The technology is now ready for mass production.

Chaff

  • It is originally called Window. The idea of using Chaff developed in the era of World War II.
  • Chaff is basically a radio frequency counter measure.
  • It consists of aluminium coated glass fibres ranging in lengths of 0.75 cm to 0.8 cm. They are released in packets of 100 million such fibres.
  • Most of the modern armed forces use chaff to distract the missiles from their targets.
  • The warships use chaff for self-defence.
  • An intercontinental ballistic missile releases chaff in its mid-course.

Recent Developments

  • In March 2021, the UXOR (Unexploded Ordnance Handling Robot) completed its user trials. It was developed for Indian Air Force and Indian Army. It can handle 1000 kilogram of ordnance.
  • In March 2021, NMRL conducted successful tests of indigenous air independent propulsion systems.
  • DRDO’s Sindhu Netra satellite was deployed in space on 28th February 2021. The main objective of the satellite is to boost the surveillance capability of India and monitor military warships and merchant shipping in the Indian Ocean Region (IOR).
