The Indian Navy is set to commission three indigenously built frontline platforms—INS Dunagiri, INS Sanshodhak, and INS Agray—at Kolkata, reinforcing India's indigenous defence manufacturing capabilities and strengthening maritime security under the vision of Aatmanirbhar Bharat.

Overview

The commissioning of these three warships marks another milestone in India's indigenous shipbuilding programme. Each platform has been designed for a specialised role, ranging from multi-role combat operations and anti-submarine warfare to hydrographic surveys, thereby enhancing the Navy's operational readiness across the Indian Ocean Region (IOR).

INS Dunagiri

INS Dunagiri is the fifth Project 17A stealth frigate, designed by the Warship Design Bureau (WDB) of the Indian Navy and built by Garden Reach Shipbuilders & Engineers Ltd. (GRSE), Kolkata.

As an advanced multi-role stealth warship, it is equipped with BrahMos supersonic surface-to-surface missiles, the Medium Range Surface-to-Air Missile (MRSAM) system, and modern sensors capable of undertaking anti-air, anti-surface, and anti-submarine warfare. The frigate significantly enhances the Navy's blue-water combat capability and fleet defence.

INS Sanshodhak

INS Sanshodhak is the fourth Survey Vessel (Large) inducted into the Indian Navy. It is designed to conduct coastal and deep-sea hydrographic surveys, besides collecting oceanographic and geophysical data for both defence and civilian purposes.

The vessel is equipped with advanced survey technologies, including Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs), enabling accurate seabed mapping, navigation support, and maritime infrastructure planning.

INS Agray

INS Agray is the fourth Arnala-class Anti-Submarine Warfare Shallow Water Craft (ASW-SWC), specifically designed for operations in shallow coastal and littoral waters.

The vessel is equipped with lightweight torpedoes, indigenous anti-submarine rocket launchers, and shallow-water sonar systems to detect and neutralize underwater threats. It will play an important role in coastal defence, maritime surveillance, and anti-submarine operations.
