Indian Navy to Commission Stealt Frigate, Anti-submarine Craft, Hydrographic Survey Vessel

The Indian Navy is scheduled to commission three indigenously built frontline platforms – Dunagiri, Sanshodhak, and Agray – in Kolkata on 21 Jun 2026.

Designed by the Indian Navy’s Warship Design Bureau and constructed by Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, the vessels represent key operational capabilities across maritime combat, hydrographic surveying, and anti-submarine warfare.

Together, they reflect the Navy’s balanced approach to capability development, strengthening blue-water operations, enhancing maritime domain awareness, and securing coastal waters against evolving threats, a government release said Friday.

Dunagiri, the fifth Project 17A stealth frigate, is equipped with advanced weapons and sensors, including BrahMos surface-to-surface missiles and the Medium Range Surface-to-Air Missile system, significantly enhancing the Navy’s combat capability.

Sanshodhak, the fourth Survey Vessel (Large), is designed for coastal and deep-water hydrographic surveys and collection of oceanographic and geophysical data for defence and civil applications, and is equipped with advanced survey systems including Autonomous Underwater vehicles and Remotely Operated craft.

Agray, the fourth of the Arnala-class Anti-Submarine Warfare Shallow Water Craft, is equipped with lightweight torpedoes, indigenous rocket launchers, and shallow-water sonar systems to detect and engage underwater threats in littoral waters.

The three platforms demonstrate the growing maturity of India’s indigenous shipbuilding ecosystem, with indigenous content exceeding 75 percent. Their construction involved extensive participation by Indian industry, including more than 200 MSMEs, and generated substantial direct and indirect employment.
