Indian Navy Receives Malwan Anti-Submarine Shallow Water Craft

06 Apr 2026 CW Team

The ship is configured for underwater surveillance and anti-submarine warfare operations in coastal waters, and it is also capable of low intensity maritime operations and mine warfare. The Waterjets propelled ASW SWC measures 80 metres in length and displaces 1,100 tonnes (t). It carries torpedoes, multifunctional anti-submarine rockets and an integrated suite of advanced radars and sonar sensors for detection and engagement. Onboard systems are configured to operate in challenging littoral environments.

With over 80 per cent indigenous content, Malwan represents a further milestone in indigenous warship construction and reaffirms the Government of India vision of Aatmanirbhar Bharat. Equipment and systems have been developed and integrated onboard by the domestic defence manufacturing ecosystem, including micro, small and medium enterprises. The name draws on the historic coastal town of Malwan in Maharashtra and continues the legacy of the erstwhile INS Malwan, which remained in service until 2003.

The delivery is intended to strengthen the Navy's coastal surveillance and anti-submarine capabilities and to enhance readiness for a range of maritime tasks. Malwan will join sister ships in the series as they enter service over the coming months, expanding the Navy's shallow water ASW footprint. The vessel exemplifies domestic shipbuilding capability and the integration of indigenous systems across naval platforms. The delivery underscores collaboration between the Navy and domestic industry for future platforms.

Malwan, the second of eight Anti-Submarine Warfare Shallow Water Craft (ASW SWC) built by Cochin Shipyard Limited (CSL) in Kochi, was delivered to the Indian Navy on 31 March 2026. The vessel was indigenously designed and constructed to Indian Navy specifications in accordance with the Classification Rules of DNV. The delivery follows contractual milestones for the series and forms part of a sustained effort to modernise coastal defence. The programme forms part of a long term plan to bolster maritime security in coastal regions.
