GRSE Hands Over 'INS Anjadip' Anti-Submarine Warfare SWC to Indian Navy

In a significant stride for indigenous defence manufacturing, Garden Reach Shipbuilders and Engineers (GRSE) Ltd delivered the INS Anjadip, the third of eight Anti-Submarine Warfare Shallow Water Crafts (ASW SWCs), to the Indian Navy on Monday at Chennai Port Trust, officials confirmed. This marks the fifth warship handed over by the Kolkata-based shipyard in 2025, underscoring GRSE’s deepening role in strengthening India’s maritime capabilities.

The vessel was formally accepted by Rear Admiral Gautam Marwaha, VSM, Chief Staff Officer (Technical), Eastern Naval Command, on behalf of the Navy. INS Anjadip is the 115th warship constructed by GRSE and the 77th delivered to the Indian Navy.

A New Asset in Coastal Defence

INS Anjadip has been indigenously designed and constructed under the Make in India initiative as part of the ASW SWC programme, jointly executed by GRSE and L&T Shipyard, Kattupalli under a public-private partnership. These vessels are built to the Indian Register of Shipping (IRS) classification standards and tailored for shallow-water anti-submarine operations.

Spanning approximately 77 metres in length, INS Anjadip is among the largest waterjet-propelled warships in the Indian Navy’s inventory. Powered by three waterjets driven by marine diesel engines, the craft achieves speeds in excess of 25 knots while requiring a shallow draught of 2.7 metres, enabling agile manoeuvrability in littoral zones.

Designed to operate with a complement of 57 personnel including seven officers, the vessel is equipped with an advanced suite of sensors and weapons tailored for sub-surface detection and engagement. Key features include:

• Sophisticated sonar systems, including hull-mounted and low-frequency variable depth sonar for enhanced underwater surveillance and target detection.

• Combat Management System and integrated platform management suites to ensure coordinated responses across surveillance, navigation, and weapons operations.

• Anti-submarine armaments such as lightweight torpedo launchers, RBU-6000 anti-submarine rocket launcher, and anti-submarine mining capability.

• Indigenous 30 mm Naval Surface Gun and stabilized remote-controlled 12.7 mm guns for surface and aerial defence.

These capabilities enable the ASW SWC class to undertake comprehensive sub-surface surveillance, search and attack missions, coordinated operations with naval aircraft, and mine-laying missions in coastal waters.

Self-Reliance in Defence Manufacturing

INS Anjadip epitomizes India’s growing defence self-sufficiency, featuring nearly 88 percent indigenous content, including weapons and key subsystems manufactured domestically. Like its predecessors – INS Arnala and INS Androth – the vessel reinforces the government’s Aatmanirbhar Bharat vision for home-grown defence solutions.

Earlier in 2025, GRSE delivered four other major warships, including the Advanced Guided Missile Frigate INS Himgiri, ASW SWCs Arnala and Androth, and the Survey Vessel (Large) INS Ikshak — all of which have since been commissioned into service, marking a rare achievement for any shipyard in the country.

Strategic Significance and Future Outlook

The ASW SWC programme was initiated under contracts signed in April 2019, when the Ministry of Defence awarded GRSE and Cochin Shipyard Limited (CSL) separate orders to build eight vessels each, aimed at replacing ageing Abhay-class corvettes and enhancing the Navy’s littoral anti-submarine warfare capability.

GRSE’s portion of the project, designated the Arnala class, is progressing steadily, with subsequent hulls already launched or under construction. Concurrently, CSL is delivering its Mahe class counterparts, broadening naval capacity across India’s coastal theatres.

With three waterjets, advanced sonar, weapons suites, and high manoeuvrability, the ASW SWCs like INS Anjadip are set to play a pivotal role in safeguarding India’s maritime frontiers against evolving undersea threats, strengthening coastal defence, and contributing to regional maritime security
