The Indian Navy will formally induct the INS Mangrol, an indigenous anti-submarine warfare shallow water craft, on 12 October 2026 at Naval Dockyard, Mumbai. The ship is the third of its class built by Cochin Shipyard Limited (CSL) in Kochi under India’s Make in India and Aatmanirbhar Bharat (self-reliant India) initiatives. Vice-Admiral Sanjay Vatsayan, Flag Officer Commanding-in-Chief of the Western Naval Command, will preside over the commissioning ceremony.
The vessel is designed to detect and neutralise underwater threats in coastal and shallow waters, where larger naval ships cannot easily operate. It carries modern weapons and sensors suited to India’s maritime security needs, and will bolster the Navy’s capacity to guard ports, harbours and coastal approaches.
Key facts
- Commissioning date: 12 October 2026
- Location: Naval Dockyard, Mumbai
- Builder: Cochin Shipyard Limited, Kochi
- Indigenous content: over 80%
- Named after: Mangrol, a coastal town and fishing harbour in Junagadh district, Gujarat
- Previous ship of the name: INS Mangrol (M85), a minesweeper that served until 7 April 2004
- Propulsion: three diesel engines with waterjet propulsion
Design and capabilities
The INS Mangrol is engineered specifically for shallow-water operations where deep-draft vessels face constraints. Its waterjet propulsion system provides high manoeuvrability, making it agile in confined coastal zones. The ship is equipped with the Abhay Hull-Mounted Sonar for underwater detection, lightweight torpedoes for anti-submarine strikes, an indigenous anti-submarine rocket launcher, and the Maareech Advanced Torpedo Decoy System for self-defence against incoming threats.
Beyond anti-submarine warfare, the vessel can undertake underwater surveillance, low-intensity maritime operations and mine-related tasks. It is designed to work in coordination with maritime patrol aircraft, helicopters and other Navy ships to locate and neutralise submarine threats across India’s coastal waters.
Indigenous shipbuilding milestone
The INS Mangrol represents a significant step in India’s domestic defence manufacturing. Constructed with over 80% indigenous content, the ship demonstrates Cochin Shipyard’s capability to design, build and integrate advanced weapons systems without heavy reliance on foreign suppliers. This aligns with the Government of India’s policy to reduce defence imports and build a self-reliant defence industrial base.
The use of Indian-made sensors and weapons, including the Abhay sonar and Maareech decoy system, shows that India’s defence research and development ecosystem can produce systems competitive with international standards. CSL’s role in executing this project underscores the potential of India’s public shipyards to deliver complex naval platforms.
Strategic significance for coastal defence
India’s long coastline and expanding maritime interests make anti-submarine capabilities critical. Larger warships optimised for open-ocean operations cannot patrol shallow coastal waters effectively. The INS Mangrol fills this gap by offering a dedicated platform for near-shore anti-submarine defence. This is particularly relevant as submarine technology becomes more sophisticated and accessible to various actors in the Indian Ocean region.
The ship will enhance the Navy’s ability to protect vital sea lanes, shipping routes and port approaches. It also enables the Navy to respond swiftly to underwater incursions in areas where traditional capital ships would be too large or too slow to deploy.
Connection to earlier ships
The naming honours the legacy of the earlier INS Mangrol (M85), a minesweeper that served the Indian Navy for several decades until its decommissioning in 2004. This practice of recycling ship names reflects naval tradition and historical continuity. The new Mangrol inherits not just a name but an association with coastal and shallow-water operations, as minesweepers historically operated in such zones.
What this means for you
For citizens, the induction of the INS Mangrol reinforces India’s ability to safeguard its coasts and maritime interests independently. It reduces dependence on foreign military hardware and showcases Indian engineering capability. For those in defence manufacturing and shipbuilding, it validates the potential of domestic yards and suppliers. For competitive exam aspirants in defence and current affairs, this commissioning represents progress in India’s self-reliance goal in defence production.
