About the Tri-Commissioning

  • This event marked the simultaneous induction of three different naval ships built for unique strategic needs.
  • These platforms show the Indian Navy plan to build large warships for deep seas, mapping vessels for oceans, and fast coastal hunters for local security.

INS Dunagiri The Blue-Water Combatant

  • This ship is a heavy, stealth guided-missile frigate built under the advanced Project 17A.
  • Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata built this warship.
  • The main goal is to sail far out into the deep sea and fight enemy threats across distant waters.
  • It uses a stealth design geometry to hide from enemy radars.
  • The ship carries BrahMos surface-to-surface missiles and a MRSAM defense system for long-range strikes.
  • It has a powerful sensor suite including the MFSTAR radar and sonar systems.
  • It belongs to a family of frigates that includes INS Nilgiri, Himgiri, Taragiri, Udaygiri, and Vindhyagiri.

INS Sanshodhak The Deep-Water Surveyor

  • This is the fourth and final Survey Vessel - Large (SVL) belonging to the Sandhayak-class fleet.
  • Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata developed this ship.
  • Its purpose is to map ocean floors, help naval submarines plan safe routes, and create charts for civilian ships and disaster relief.
  • It collects hydrographic data, studies seabeds, measures water depths, and maps port channels.
  • The ship carries advanced research gear like Autonomous Underwater Vehicles (AUVs), ROVs, and echo sounders.
  • It follows sister ships INS Sandhayak, Nirdeshak, and Ikshak under a contract signed in 2018.

INS Agray The Coastal Submarine Hunter

  • This vessel is an Anti-Submarine Warfare Shallow Water Craft (ASW SWC) from the Arnala-class.
  • Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata built this agile craft.
  • Its goal is to find, track, and destroy enemy submarines hiding in shallow coastal waters.
  • It protects vital areas like commercial ports, naval bases, and coastal routes.
  • The ship is designed to ignore background noise from fishing boats, merchant ships, and reefs in shallow water.
  • It is armed with lightweight anti-submarine torpedoes, sonars, and rocket launchers.
