Navy to commission third Mahe-class vessel INS Mangrol in Mumbai on October 12

Mumbai: The navy will commission INS Mangrol, the third Mahe-class anti-submarine warfare shallow water craft built by

Cochin Shipyard Ltd, at the Naval Dockyard here on October 12. Built with more than 80% indigenous materials, the vessel will conduct underwater surveillance, anti-submarine exercises, mine operations, low-intensity maritime operations and coastal security missions. It will patrol coastal waters and monitor small and diesel submarines.

INS Mangrol is named after a minesweeper that served the navy from 1983 to 2004. Mangrol is a historic coastal town, minor port and marine fishing harbour in Gujarat’s Junagadh district.

The vessel is equipped with electronic support measures, electronics intelligence, a combat management system, DRDO’s Abhay compact hull-mounted sonar and a low frequency variable depth sonar.

Its weapons include a forward-mounted rocket launcher, two triple lightweight torpedo launchers with advanced lightweight torpedoes, a 30mm naval surface gun, and two 12.7 mm stabilised remote-controlled guns. Integrated rails allow it to lay mines, while its anti-submarine warfare defence suite includes Mahindra’s torpedo decoy launching systems.

The craft also has an Integrated platform management system and battle damage control system.

Three marine diesel engines connected to three advanced waterjet propulsors provide a combined output of 6 MW. The system reduces underwater noise, making the vessel less susceptible to detection by enemy submarines.

Built to Det Norske Veritas classification standards, INS Mangrol has a displacement of 896 to 1,100 tonnes, a beam of 11.26 and a draft of 2.7m. It can reach 25 knots, or about 46 km an hour, and has a range of 1,800 nautical miles at a cruising speed of 14 knots.

The vessel has an endurance of 14 days and can accommodate 57 people, including seven officers and 50 sailors.

The Ministry of defence and Cochin Shipyard Ltd signed a contract for eight ASW-SWC vessels on April 30, 2019. The first three are named after strategic coastal ports and towns: INS Mahe, INS Malvan and INS Mangrol. INS Mahe was commissioned in November 2025 under Western Naval Command, while INS Malvan was commissioned at Karwar on July 22.
