Three indigenous warships were officially commissioned into the Indian Navy today, marking an unforgettable milestone in India’s relentless pursuit of absolute defense self-reliance.
In a historic and power-packed ceremony held at Kolkata’s Syama Prasad Mookerjee Port, Prime Minister Narendra Modi officially dedicated the trio of frontline naval platforms to the nation. The simultaneous commissioning of an advanced stealth frigate, a massive hydrographic survey vessel, and a cutting-edge anti-submarine shallow water craft is a rare feat in global naval history, sending a definitive message about India’s skyrocketing domestic defense manufacturing capabilities.
The event, which perfectly coincided with both International Yoga Day and World Hydrography Day, was attended by top-tier dignitaries, including West Bengal Governor RN Ravi, Chief Minister Suvendu Adhikari, and Chief of the Naval Staff Admiral Krishna Swaminathan.
A Triple Threat to Maritime Adversaries
The induction of these three indigenous warships—INS Dunagiri, INS Sanshodhak, and INS Agray—reflects the Indian Navy’s meticulously balanced strategy to enhance blue-water combat dominance, sharpen maritime domain awareness, and airtight coastal security against rapidly evolving underwater and surface threats.
Designed entirely by the Indian Navy’s in-house Warship Design Bureau and constructed by the premier defense public sector undertaking, Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata, these vessels stand as phenomenal masterpieces of modern engineering.

INS Dunagiri: The Decisive, Dauntless Combat Titan
Dominating the trio in terms of sheer firepower is INS Dunagiri, an advanced stealth frigate engineered for long sea legs, high agility, and sustained independent operations in hostile environments.
Prior to the commissioning, the Indian Navy released a video highlighting the ship’s lethal capabilities, describing it with three powerful words: “Precision. Power. Agility.” The Navy further stated:
“Packed with state-of-the-art weapon and sensor suites, engineered for long sea legs, sustained operations and equipped with indigenous stealth technology, Dunagiri is built for multi-dimensional dominance and lethality. Dunagiri: Decisive Dauntless Dominant.”
Lethal Arsenal and Stealth Features
Dunagiri is not just a defensive shield; it is a highly aggressive weapon system. It comes equipped with the world-renowned BrahMos surface-to-surface supersonic cruise missiles, capable of neutralizing enemy warships and land targets at extreme ranges with pinpoint precision. For air defense, it features the Medium Range Surface-to-Air Missile (MR-SAM) system, designed to eliminate incoming enemy aircraft, drones, and anti-ship missiles.
Combined with advanced radar-evading structural geometry (stealth technology), Dunagiri can operate undetected in high-threat zones, striking enemies before they even realize it is there.
INS Sanshodhak: The Guardian of the Deep Ocean Floor
The commissioning of INS Sanshodhak holds a beautiful, symbolic significance. Inducted precisely on June 21—World Hydrography Day—this vessel is the fourth in the series of Survey Vessels (Large) built for the Navy.
Advanced Undersea Mapping Capabilities
Sanshodhak, which literally translates to “Researcher,” is designed for both shallow coastal waters and deep-ocean hydrographic surveys. It plays a dual strategic role:
Defense Operations: Mapping unknown underwater terrains, identifying safe routes for Indian submarines, and detecting underwater anomalies or enemy assets.
Civil Applications: Collecting vital oceanographic and geophysical data to aid marine scientific research, environmental protection, and trade navigation safety.
To achieve this, the vessel is packed with ultra-modern survey systems, including highly sophisticated Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs) that can dive deep into the ocean abyss to transmit real-time data back to the command center.
INS Agray: Shaking Up Enemy Submarines in Shallow Waters
As underwater threats grow in the Indian Ocean Region, protecting India’s extensive coastline and shallow littoral waters has become a paramount priority. Enter INS Agray, the fourth of the Arnala-class Anti-Submarine Warfare Shallow Water Craft (ASW SWC).
Neutralizing Underwater Threats
Enemy submarines often attempt to sneak into shallow coastal waters to avoid detection by large deep-sea sonar arrays. INS Agray is custom-built to hunt down these exact threats. Equipped with:
State-of-the-art, high-frequency shallow-water sonar systems optimized for complex coastal acoustics.
Devastating lightweight anti-submarine torpedoes for immediate engagement.
Highly effective indigenous rocket launchers to destroy subsurface targets.
Agray ensures that India’s vital ports, industrial hubs, and coastal shipping lanes remain entirely impenetrable to foreign underwater incursions.
PM Narendra Modi’s Vision: “Our Military Power Cannot Be a Market for the World”
Addressing the gathered crowd of scientists, engineers, sailors, and citizens in Kolkata, Prime Minister Narendra Modi delivered an incredibly passionate and visionary speech. He tied the commissioning of these three vessels directly to India’s grand national goals of Atmanirbhar Bharat (Self-reliant India), Surakshit Bharat (Secure India), and Viksit Bharat (Developed India).

The Spirit of Bengal and National Renaissance
The Prime Minister began by acknowledging the deeply rich historical and maritime heritage of West Bengal, a land that has shaped India’s identity for centuries.
“I am pleased that on this occasion I have had the opportunity to come to this great land of Bengal,” PM Modi said. “This is the land that gave new direction to India’s ideas, that accelerated India’s renaissance, and that for centuries connected India to the world through the sea. Today, on this very soil, an important program linked to Atmanirbhar Bharat, Surakshit Bharat, and Viksit Bharat is taking place.”
Shifting from Global Buyer to Global Builder
In a stern and clear message regarding India’s defense posture, the Prime Minister emphasized that India will no longer accept being dependent on foreign nations for its security needs. He pointed out that true sovereignty stems from domestic design and manufacturing.
“These three ships symbolise three important resolutions of India. They were built in India, designed in India. They are the result of the talent of Indian industries, the skill of Indian engineers, and the hard work of Indian workers, and this is the greatest strength of the new India. Today India no longer wants to remain a mere buyer in the defence sector. Our military power cannot become a market for the world. The definition of our strength does not lie in becoming the world’s market. The definition of our power lies in my self-reliance.”
The Incredible Leap from INS Vikrant to Today
PM Modi reminded the nation of the historic commissioning of India’s first indigenous aircraft carrier, INS Vikrant, a few years ago, noting that it opened a brand-new chapter in the country’s defense narrative. He stated that the momentum has only accelerated since then.
“A country whose maritime power is strong will also have a strong economic and strategic influence and India understands this reality well,” the Prime Minister explained. “India is preparing itself for this, and today is a testament to our capabilities and our skills. A few years ago, when we dedicated INS Vikrant to the nation, India announced a new chapter in its maritime power. That was a declaration of our strength to the world. The journey from INS Vikrant to today is not just a journey of new warships; it is also a journey of India’s growing self-reliance. Today, INS Agray, INS Dunagiri, and INS Sanshodhak are giving new impetus to that journey.”
Economic and Strategic Impact of Localized Warship Building
The simultaneous manufacturing and induction of these platforms highlight a massive shift in India’s macroeconomic landscape. By relying heavily on Garden Reach Shipbuilders & Engineers (GRSE) and a sprawling network of domestic MSMEs (Micro, Small, and Medium Enterprises), the Indian Navy’s expansion is actively fueling economic growth at home.
1. Job Creation and Skill Development
Every warship built locally requires millions of man-hours. From the initial conceptual blueprints drafted by the Warship Design Bureau to the complex structural welding, electrical cabling, and weapon integration executed at the Kolkata shipyard, thousands of Indian engineers, technicians, and manual laborers have found high-value employment.
2. Boosting Private Industry and MSMEs
Modern warships are complex ecosystems. GRSE works hand-in-hand with hundreds of private Indian vendors who supply specialized steel, localized sonar components, advanced computational hardware, and marine-grade paints. This symbiotic relationship strengthens India’s industrial backbone, making private enterprises globally competitive.
3. Geopolitical Balance in the Indian Ocean Region (IOR)
The Indian Ocean has fast become a hotbed of geopolitical maneuvering, with foreign survey vessels and stealth submarines frequently charting its waters. By deploying three indigenous warships with vastly diverse operational capabilities, India asserts its rightful position as the net security provider in the region.
Dunagiri ensures deterrence against surface fleets.
Agray locks down the coastal choke points against subsurface intruders.
Sanshodhak ensures that India maps its own maritime economic zones perfectly, denying adversaries an informational advantage.
Conclusion: A Resilient Maritime Future Beckons
The tri-commissioning ceremony in Kolkata will undoubtedly go down in history as a watershed moment for India’s defense forces. It proves that the nation possesses the vision, talent, and industrial capacity to secure its borders using weaponry forged in its own foundries.
As INS Agray, INS Dunagiri, and INS Sanshodhak hoist the naval ensign and sail out into the open ocean, they carry with them the pride of 1.4 billion citizens. They are not merely cold steel and complex circuitry; they are floating testaments to a self-reliant, secure, and fully developed India.
The Indian Navy’s journey toward a 100% indigenous fleet by 2047 is no longer an idealistic dream—it is an unfolding reality happening right before our eyes.
