Indian Navy Warships: Strategic Importance and Indigenization

Today, June 21st. Prime Minister Modi stood on the Hooghly in Kolkata. He commissioned three Indian Navy warships built entirely at home. Dunagiri, Sanshodhak, and Agray. They landed at Garden Reach Shipbuilders & Engineers that massive public sector yard that actually built them from keel to final polish.

It wasn't just a handover ceremony. It happened right when the Navy was seriously worried. Underwater surveillance. Gaps in the Indian Ocean. That’s where things got tense.

The focus, really, is on what these ships do . They aren't just metal; they address deep strategic worries about underwater and surveillance blind spots across the region.

We have Dunagiri. It’s one of those frontline platforms. Then there’s Sanshodhak. And Agray. Three things, tied together by this single event.

The Navy had been ordering frigates for a while. Seven Project 17A frigates were on the table four from Mazagon Dock and three from GRSE. Dunagiri is the fifth one out of that batch. The second built at Garden Reach. Six of those seven are now delivered. But there’s still Vindhyagiri coming, due in 2027. That one carries BrahMos missiles and the MRSAM system. It can hit ships. Shoot down planes or incoming rockets. A real frontline piece.

And then you have Sanshodhak. This one wraps up a different class: the Survey Vessel (Large) category. GRSE signed off on all four of those back in 2018. Sandhayak, Nirdeshak, Ikshak those are already sailing around doing their mapping jobs. Sanshodhak’s job is charting everything. Ports, channels, the deep ocean floor using sonar and underwater vehicles. It might not be visible on the surface. But that capability? Strategically vital.

Agray is another piece of this puzzle. It’s part of a bigger build eight Arnala-class anti-submarine boats GRSE is working on. That contract was worth over six thousand crore rupees. Three are still being built. Ajay, the last one, is already launched. Cochin Shipyard is building eight more similar ones, the Mahe class. So the Navy ends up with sixteen of these total. Agray itself is designed for shallow water. Torpedoes. Anti-submarine rockets. Sonar. It’s about finding and hitting submarines close to shore. An area where the Navy has always felt a bit thin.

China. That shadow looms large. They've had more subs moving through the Indian Ocean these last ten years. The Navy had to recalibrate everything. Tracking what happens underwater isn't optional anymore. It’s treated like surface tracking. Because Chinese deployments keep growing, that pressure just mounts.

The seabed itself is contested terrain now. Chinese survey vessels are mapping the ocean floor. New Delhi sees this as Beijing sharpening its own submarine and oceanographic intelligence picture. And this is where a vessel like Sanshodhak comes in. It helps India build its own map. An independent view of its waters. Of those contested approaches. Knowing the ocean better than a rival? That’s part of undersea deterrence now. Not just some nice bonus later on.

Sea lane security adds another layer of pressure. The surveillance push, expanding patrol fleets like that P-8I plan it all reflects that deep concern inside the Navy. Submarine activity. Maritime competition. Surveillance gaps across the whole Indo-Pacific. Officials are saying persistent maritime domain awareness isn't optional anymore. It’s indispensable.

Dunagiri handles the strike power. Missile and air defense escort for merchant ships moving through these waters. The three commissions strike, seabed knowledge, undersea defense they fit together oddly well. An unusually complete answer to an unusually layered threat picture.

None of this would matter much if they had to buy it all from somewhere else. That’s the core issue. These ships, delivered on March 30th, 2026, bring GRSE's total tally up to 118 warships built. Eighty of those went to the Indian Navy. The yard itself has exported and won commercial deals. They even got that Navratna status this year because of that record. It proves the capability isn't just for domestic orders anymore. It’s feeding an export pipeline now.

Atmanirbhar Bharat . That phrase gets used loosely, often as a shortcut. A deal favoring a local vendor. This commissioning is actually more specific than that slogan suggests. These three platforms have over seventy-five percent indigenous content. They involve more than two hundred Indian MSMEs in the construction process. That’s what separates a ship built here from one assembled with imported parts under an Indian flag. It means sensors, weapons integration, and the hull it’s all designed and built at home.

The defense production story is huge. Under Modi's leadership, it shot up from about forty-six thousand crore in 2014-15 to nearly one lakh seventy-eight thousand crore by 2025-26. Exports jumped too. From a mere six hundred eighty-six crore to a record thirty-eight thousand four hundred twenty-four crore over that decade. That growth wasn't magic.

Tools like the Positive Indigenisation Lists stepped in. They banned imports on thousands of defense items. And portals like SRIJAN are now registering over forty thousand vendors just for components. These three ships, commissioned at one yard in Kolkata? They’re just a tiny piece of that massive decade-long push. A slice showing the policy actually working.

Three warships sliding into commission because of what they were built to do, not just where they sat. It highlights two parallel tracks shaping India's maritime strategy: watching this increasingly contested Indian Ocean, and desperately building the capability to watch it at home.

The harder test now is whether GRSE can keep up that indigenisation rate. Can they maintain that delivery pace? As the Navy’s needs get messier as the threats evolve and if those export wins turn into something lasting, not just occasional deals. For the Navy itself, this induction closes gaps in surveillance, undersea warfare, and fleet support. Another step forward. A necessary one.
