This week, the Indian Navy is set to execute a massive projection of maritime power. In an exceptionally rare event, India is commissioning three frontline warships on the exact same day. Prime Minister Narendra Modi is expected to attend this monumental commissioning ceremony in Kolkata on June 21, 2026.
Crucially, all three of these advanced naval platforms are completely “Made in India.” This is only the second triple commissioning of frontline naval platforms in recent years—the previous one occurring earlier in January when INS Surat, INS Nilgiri, and INS Vaghsheer entered service together. However, what makes this upcoming induction so spectacular is not just the number of ships involved, but the lethal, calculated mix of capabilities they bring to the fleet.
The Strategic Mix: Why These Three Warships?
These are not three random platforms entering service together. They have been specifically designed and deployed to address three entirely distinct tactical challenges the Indian Navy faces in the contested waters of the Indian Ocean Region (IOR).
Here is exactly what is joining the fleet:
INS Dunagiri: The Stealth Predator
INS Dunagiri is a Project 17A stealth frigate designed for high-end surface and anti-air warfare. It is the offensive muscle of this trio. Armed with the deadly BrahMos supersonic cruise missiles and the Barak-8 surface-to-air missile system, Dunagiri is a heavily armed combatant capable of striking targets deep over the horizon while remaining hidden from enemy radar.
INS Agray: The Submarine Hunter
The INS Agray is an Arnala-class anti-submarine warfare (ASW) shallow water craft. As adversaries like China and Pakistan rapidly expand their submarine fleets, India requires dedicated sub-hunters to protect its coastal waters and naval bases. The Agray is designed exactly for this—to actively hunt, track, and destroy hostile submarines lurking in the shallow littoral zones before they can threaten Indian carrier strike groups.
INS Sanshodhak: The Deep-Sea Visionary
A missile can only hit what it can find. INS Sanshodhak is an advanced survey ship equipped with Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs). This vessel is responsible for critical seabed mapping and underwater data collection. It helps the Navy thoroughly understand the underwater battlespace, providing the acoustic and topographical intelligence necessary for submarines and surface ships to operate effectively.
The Victory of Aatmanirbhar Bharat
Beyond their tactical roles, these three platforms represent a massive victory for India’s indigenous defense manufacturing. Across all three vessels, there is more than 75 percent indigenous content. This means that from the steel used in their hulls to the complex electronic warfare systems inside, the Indian Navy is no longer held hostage by foreign supply chains.
Furthermore, the speed of domestic production has significantly increased. The INS Dunagiri was successfully delivered in just 80 months, a sharp improvement compared to the 93 months it took to deliver the lead ship of its class, INS Nilgiri.
Securing the Indian Ocean Region
Look at the mix carefully: One ship carries BrahMos missiles. One hunts submarines. One maps the underwater battlespace. By simultaneously inducting a surface combatant, a sub-hunter, and an intelligence-gathering vessel, the Indian Navy is making a profound strategic statement. As geopolitical tensions rise, India is not just buying ships; it is building a comprehensive, self-reliant maritime ecosystem designed to absolutely dominate the Indian Ocean
