PM Modi Commissions Three Indigenously Built Indian Navy Platforms in Kolkata

A Historic Triple Commissioning Ceremony

In a major boost to India's maritime defense capabilities and self-reliance initiatives, Prime Minister Narendra Modi commissioned three indigenously designed and constructed warships for the Indian Navy in Kolkata on June 21, 2026. The simultaneous commissioning of three distinct platforms, designed for varied combat and support roles, represents a rare operational milestone. The vessels—INS Dunagiri, INS Sanshodhak, and INS Agray—were built by Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, having been formally delivered to the Navy earlier on March 30, 2026. The triple commissioning highlights the growing capacity of Indian shipyards to manufacture advanced combat platforms locally.

Combat and Operational Profiles of the Warships

The three commissioned vessels serve distinct tactical requirements for the Indian Navy:

• INS Dunagiri (P17A Stealth Frigate): The fifth ship of the Project 17A stealth frigate program. It features advanced stealth capabilities, a low radar cross-section, and is armed with the BrahMos supersonic cruise missile system and sophisticated surface-to-air missile defenses, making it a frontline multi-role combatant.
• INS Sanshodhak (Survey Vessel Large): The fourth and final ship of the Sandhayak-class Survey Vessel (Large) program. Equipped with state-of-the-art hydrographic sensors, sonar systems, and data-processing tools, it will conduct oceanographic and hydrographic surveys, which are critical for naval operations and navigation charts.
• INS Agray (ASW Shallow Water Craft): The fourth ship of the Arnala-class Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) program. It is optimized for littoral anti-submarine warfare, sub-hunting operations in coastal waters, and mine-laying missions, bolstering defense against underwater threats in shallow seas.

Strengthening Aatmanirbhar Bharat in Defence

The construction of these platforms showcases a high degree of indigenous content, exceeding 75% across materials, machinery, and armaments. By partnering with domestic micro, small, and medium enterprises (MSMEs) and leveraging indigenous design expertise, the project aligns with the national vision of self-reliance (Aatmanirbhar Bharat) in defense production. The addition of these platforms provides the Indian Navy with enhanced capability to secure the Indian Ocean Region (IOR), protect vital trade corridors, and conduct maritime surveillance in the face of rising regional geopolitical competition.
