Kolkata / New Delhi: Marking a historic milestone in India’s indigenous defense manufacturing journey, Prime Minister Narendra Modi simultaneously commissioned three major warships into the Indian Navy at Kolkata.
The simultaneous commissioning of three complex surface combatants designed and constructed by a single shipyard is a first for India. The mega naval event unfolded in the presence of West Bengal Governor R N Ravi, Chief Minister Suvendu Adhikari, and Chief of the Naval Staff Admiral Krishna Swaminathan.
The trio of frontline vessels—INS Dunagiri, INS Sanshodhak, and INS Agray—underscores the rapidly expanding capabilities of Garden Reach Shipbuilders & Engineers Ltd (GRSE) under the government’s Aatmanirbhar Bharat initiative.
Meet the Trio: A Powerful Boost to India’s Naval Fleet
Each of the three newly commissioned warships brings highly specialized, high-tech combat and strategic capabilities to the Indian Navy.

GRSE: India’s Leading Indigenous Warship Producer
With the successful triple delivery of these combat vessels, GRSE has now built and delivered 118 warships—including 80 specifically commissioned for the Indian Navy—cementing its position as the country’s most prolific defense shipyard.
Prime Minister Narendra Modi Highlighted: “The commissioning of these three vessels reflects India’s growing self-reliance in defense manufacturing. Built with the contribution of domestic industries, engineers, and workers, they represent the strength of a new, self-reliant India.”
Chief of the Naval Staff Admiral Krishna Swaminathan reiterated that GRSE remains a deeply trusted partner in safeguarding maritime boundaries, emphasizing that the tri-commissioning proves India’s technological jump in heavy shipbuilding.
The Road Ahead: 90% Indigenisation & Export Goals
GRSE revealed that its frontline warships now integrate more than 90 percent indigenous equipment. The Defense PSU is aligning its master strategy with Maritime India Vision 2030 and Maritime Amrit Kaal Vision 2047 by weaponizing AI, digitizing shipyards, and deploying sustainable building practices.
The shipyard’s robust pipeline currently features:
One remaining Project 17A advanced stealth frigate.
Four Anti-Submarine Warfare Shallow Water Crafts.
Four Next-Generation Offshore Patrol Vessels (NGOPVs).
30 additional vessels, including 13 export platforms destined for international navies.
