Singh congratulated DRDO, Dto safeguard the naval ships Chaff is a passive expendable Indian Navy and Industry for the against enemy missile attack. electronic countermeasure achievement. Defence Laboratory Jodhpur technology used worldwide to Secretary Department of (DLJ) has indigenously developed protect naval ships from enemy’s Defence R&D & Chairman DRDO three variant, viz., Short Range radar and Radio Frequency (RF) Dr G Satheesh Reddy appreciated Chaff Rocket (SRCR), Medium missile seekers. The importance the efforts of the teams involved Range Chaff Rocket (MRCR) of this development lies in the in the indigenous development of and Long Range Chaff Rocket fact that very less quantity of chaff this vital technology to safeguard (LRCR) of this critical technology material deployed in the air acts as Indian Naval Ships. Vice Chief of meeting Indian Navy’s qualitative decoy to deflect enemy’s missiles Naval Staff Vice Admiral G Ashok requirements. The successful for safety of the ships. DRDO has Kumar applauded DRDO for development of Advanced Chaff developed the expertise in this developing strategically important Technology is another step towards area to meet the futuristic threats technology indigenously in a short Atmanirbhar Bharat. Indian Navy from adversaries. The technology span. has successfully conducted trials is being given to the industry for of all three variants in the Arabian production in large quantities. LIGHT WEIGHT BULLET PROOF JACKET efence Materials and Stores survivability. This technology Research and Development reduces the weight of the medium DEstablishment (DMSRDE), sized BPJ from 10.4 to 9 kg. Very Kanpur has developed lightweight specific materials and processing Bullet Proof Jacket (BPJ) weighing technologies have been developed 9 kilogrammes meeting the by the DRDO for the purpose. qualitative requirements of Indian Raksha Mantri Shri Rajnath Army. Singh congratulated DRDO The Front Hard Armour and industry for developing Panel (FHAP) jacket was tested the lightweight BPJ to make at Terminal Ballistics Research the soldiers more comfortable.
