Varunastra: Indigenous Heavy Weight Torpedo

Testing Success: The Indian Navy successfully test-fired the Varunastra, an indigenously built and developed heavy weight torpedo (HWT) carrying a live warhead.

Varunastra: Specifications

  • Varunastra is a ship-launched anti-submarine torpedo with low drift navigational systems, acoustic homing, improved acoustic countermeasures, autonomous guidance algorithms, an insensitive munitions warhead, and a GPS-based practise torpedo recovery aid.
  • NSTL designed and developed: Varunastra was planned and constructed by the Defence Research and Development Organisation’s (DRDO) Naval Science and Technological Laboratory (NSTL) at Vizag.
  • Manufacturing by BDL: Bharat Dynamics Ltd (BDL) is in charge of Varunastra’s production.

Capabilities and technical specifications

  • Varunastra can go at a maximum speed of 40 knots and a maximum operational depth of 600 metres. It is capable of long-distance and multi-maneuvering.
  • Acoustic homing and tracking: The torpedo has a wide look angle and acoustic homing, allowing it to follow silent targets successfully.
  • Varunastra incorporates autonomous advanced guidance algorithms as well as drift navigational technologies, allowing for precision targeting and long-endurance operations.

The Importance of the Test Fire

  • Anti-submarine torpedo: Varunastra is planned to replace previous torpedoes capable of shooting HWT as the principal anti-submarine torpedo for all naval warships.
  • Anti-submarine warfare has been improved. Varunastra’s selection as the primary anti-submarine torpedo increases the Indian Navy’s ability to confront underwater threats.
  • Self-sufficiency and indigenous development Varunastra’s successful development and deployment demonstrate India’s progress in indigenous defence technologies, reducing reliance on imports.
