GRSE launched 'Shruti', the second Next Generation Offshore Patrol Vessel, at its Kolkata shipyard on August 11, 2026.
The vessel is designated Yard 3037 and was launched by Mrs Manika Sadhu.
It follows Sanghmitra, launched on May 20, 2026 — under three months apart.
The NGOPV programme covers 11 vessels, of which GRSE is building four and Goa Shipyard Limited the rest.
The vessels will strengthen maritime surveillance across India's exclusive economic zone.
An OPV is a lightly armed, long-endurance ship built for policing rather than fighting. Its work is maritime surveillance, anti-piracy patrol, protection of offshore assets, fisheries protection and search-and-rescue across the Exclusive Economic Zone. Because it is not designed for high-intensity combat, it costs far less than a frigate or destroyer while freeing those larger warships for tasks only they can perform. India's EEZ extends 200 nautical miles from the coastline, which is why patrol vessel numbers matter as much as headline warship counts.
Simple Analogy: A patrol car rather than an armoured vehicle — built to cover ground continuously, not to win a battle.
