In news: Recently, DRDO has developed an Advanced Chaff Technology to safeguard the naval ships against enemy missile attack.

 Advanced Chaff technology

  • Three varieties: To meet meeting Indian Navy’s qualitative requirements, Defence Laboratory Jodhpur (DLJ), a DRDO laboratory, has indigenously developed three variants of this critical technology namely 
  1. Short Range Chaff Rocket (SRCR)
  2. Medium Range Chaff Rocket (MRCR) and 
  3. Long Range Chaff Rocket (LRCR) 
  • Recently, Indian Navy conducted trials of all three variants in the Arabian Sea on Indian Naval Ship and found the performance satisfactory.
  • The technology is being given to the industry for production in large quantities

What is Chaff technology?

  • Chaff is a passive expendable electronic countermeasure technology used worldwide to protect naval ships from enemy’s radar and Radio Frequency (RF) missile seekers. 
  • Chaff is a radiofrequency countermeasure released by military aircraft, ships, and vehicles to confuse enemy radar. 
  • Chaff consists of aluminum-coated glass fibers ranging in lengths from 0.8 to 0.75 cm and is released in packets of 0.5 to 100 million fibers.
  • The very less quantity of chaff material deployed in the air acts as a decoy to deflect enemy’s missiles for the safety of the ships.
