PM Modi to Commission Three Indigenous Naval Platforms in Kolkata on June 21
Prime Minister Narendra Modi will commission three indigenously-built Indian Navy frontline platforms — Dunagiri, Sanshodhak, and Agray — at a ceremony at Syama Prasad Mookerjee Port in Kolkata on June 21. The event marks a significant step in India's maritime capabilities and its indigenous shipbuilding programme.
The Prime Minister will also address the gathering on the occasion. According to the Ministry of Defence, the three vessels were designed by the Indian Navy's Warship Design Bureau and built by Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata. They represent critical capabilities across maritime combat, hydrographic surveying, and anti-submarine warfare. Their induction underscores the Navy's balanced force development strategy aimed at enhancing blue-water operations, maritime domain awareness, and coastal security.
Dunagiri is the fifth Project 17A stealth frigate. It is equipped with advanced sensors and weapon systems, including BrahMos supersonic cruise missiles and the Medium Range Surface-to-Air Missile (MRSAM) system. The warship enhances the Navy's ability to undertake multi-dimensional combat operations at sea.
Sanshodhak is the fourth large survey vessel. It is designed to conduct coastal and deep-water hydrographic surveys while collecting oceanographic and geophysical data for both defence and civilian applications. The vessel is equipped with modern survey technologies, including autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs), enabling precise seabed mapping and maritime data collection.
Agray is the fourth vessel of the Arnala-class anti-submarine warfare shallow watercraft. It is designed to detect and neutralise underwater threats in coastal and littoral waters. It is armed with lightweight torpedoes, indigenous rocket launchers, and advanced shallow-water sonar systems.
The three platforms highlight the growing strength of India's indigenous shipbuilding ecosystem, with indigenous content exceeding 75%. Their construction involved extensive participation from Indian industry, including over 200 MSMEs, generating significant direct and indirect employment opportunities.
The commissioning of the vessels reflects the collective efforts of the Indian Navy, the Government of India, public sector shipyards, private industry, and MSMEs in strengthening India's maritime security architecture.
