Description :
  • SMART is a lightweight anti-submarine torpedo system with missile assisted release for anti-submarine warfare (ASW) activities far beyond torpedo range.
  • When launched from a warship or a truck-based coastal battery, SMART operates similarly to a regular supersonic missile.
  • With a two-way data link from the warship or an airborne submarine target detection system, it covers the majority of its flight in the air at lower altitudes and delivers the exact location of the hostile submarine to correct its flight path midway.
  • The missile will eject the torpedo system into the water when it approaches the submerged submarine, and the autonomous torpedo will begin travelling towards its target to destroy the submarine.
  • Torpedoes are self-propelled underwater weapons that can be launched from a submarine, a surface vessel, or an aeroplane and are designed to explode when they come into contact with the hulls of surface boats and submarines.
  • Varunastra is the first indigenously built heavyweight ship to fire an anti-submarine torpedo.


  • Importance:


  • Enhances the country's strategic marine capabilities.
  • A huge development in anti-submarine warfare stand-off capability.
  • Project 28, a class of anti-submarine warfare corvettes now in service with the Indian Navy, was approved in 2003. INS Kamorta, INS Kadmatt, INS Kiltan, and INS Kavaratti are among them.
  • The Indian Navy's Project 75 involves the construction of six Scorpene-class assault submarines (Kalvari, Khanderi, Karanj, Vela, Vagir and Vagsheer).
