GRSE delivers three warships to Indian Navy

Indian shipbuilder Garden Reach Shipbuilders & Engineers (GRSE) has delivered three frontline naval platforms, Dunagiri, Sanshodhak, and Agray, to the Indian Navy.

As informed, the delivery ceremony took place on March 31, 2026. According to GRSE, this first-of-its-kind achievement underscores its “strengthened execution capabilities, enhanced production capacity, and its ability to deliver multiple complex naval platforms within aligned timelines”.

Dunagiri is the fifth ship of the Nilgiri class and the second guided-missile frigate built by GRSE under Project 17A. The vessel was launched in 2022 and represents one of the most sophisticated ships built by GRSE.

Designed by the Warship Design Bureau (WDB) and overseen by the Warship Overseeing Team (Mumbai), P17A frigates reflect a generational leap in indigenous ship design, stealth, survivability, and combat capability. The units are equipped with an advanced weapon and sensor suite, surpassing that of the P17 (Shivalik) class.

These ships are configured with combined diesel or gas (CODOG) propulsion plants, comprising a diesel engine and a gas turbine that drive a controllable pitch propeller (CPP) on each shaft, and a modern integrated platform management system (IPMS).

The potent weapon and sensor suite comprises BrahMos SSM, MFSTAR and MRSAM complex, 76mm SRGM, and a combination of 30 mm and 12.7 mm close-in weapon systems, along with rockets and torpedoes for anti-submarine warfare.

Sanshodhak is the fourth and final survey vessels (large) built by GRSE. The contract for four Survey Vessel (Large) ships was signed in 2018. The previous ships of the same class, INS Sandhayak, INS Nirdeshak, and INS Ikshak, were commissioned in February 2024, December 2024, and November 2025, respectively.

The ship has been designed and built by Garden Reach Shipbuilders & Engineers in accordance with the classification rules of the Indian Register of Shipping.

The vessel is intended to conduct full-scale coastal and deep-water hydrographic surveys, including port and harbour approaches, as well as the identification of navigational channels and routes. Its operational scope also includes the collection of oceanographic and geophysical data for both defence and civilian applications.

With a displacement of around 3,400 tons and an overall length of 110 meters, Sanshodhak is equipped with advanced hydrographic systems, including a data acquisition and processing suite, autonomous underwater vehicle (AUV), a remotely operated vehicle (ROV), DGPS-based long-range positioning systems, and digital side-scan sonar.

The keel was laid in June 2022, followed by its launch in June 2023. Prior to delivery, the ship completed an extensive series of harbour and sea trials.

Agray, one of the eight anti-submarine warfare shallow water crafts (ASW-SWCs), is the fourth of eight units built by GRSE.

These ships, approximately 77 metres in length, are the largest Indian naval warships propelled by waterjets and are equipped with lightweight torpedoes, indigenous rocket launchers, and shallow water SONAR, enabling effective detection and engagement of underwater threats. The induction of the ship will further augment the Indian Navy’s anti-submarine and mine-warfare capabilities, as well as coastal surveillance.
