  • An autonomous underwater vehicle (AUV) designed to detect mines and a first of its kind in the country was launched.


  • The AUV named 'Neerakshi' is a collaboration of Kolkata-based warship maker Garden Reach Shipbuilders and Engineers (GRSE) Ltd and MSME entity AEPL.
  • The AUV was named “Neerakshi”(meaning “Eyes in the Water”)
  • The lightweight and man-portable AUV has been designed to operate in a totally autonomous manner and its modular design enables it to carry out a variety of roles depending on the payload.
  • The 2.15m long AUV will have an endurance of nearly 4 hours and is capable of operating up to a depth of 300m.
  • These AUVs once in operation by our Armed Forces, could play an important role in mine countermeasure operations and also make excellent reusable targets during Anti-Submarine Warfare (ASW) practices by warships.
  • They can also be deployed for passive acoustic monitoring during which they could remain in position for prolonged durations, monitoring the possible movement of sub-surface platforms.
  • This can be used for a variety of functions ranging from mine detection to mine disposal to underwater survey.
  • Once the user trials are complete, and user requirements are incorporated, commercial production of the AUV will commence.
  • Efforts are in place to increase its endurance by 200-300%, enabling it to be deployed for coastguard duties either from a mother ship or the coast.
