PIB TrackerNavy receives anti-submarine craft Amini from GRSE
GRSE Kolkata delivered Amini, an indigenously designed Anti-Submarine Warfare Shallow Water Craft with over 80 per cent indigenous content, to the Indian Navy on 5 November 2026; it carries the name of a ship decommissioned in 2002.
What happened
- Amini, an Anti-Submarine Warfare Shallow Water Craft, was delivered to the Indian Navy on 5 November 2026.
- It was designed and built by GRSE, Kolkata, to the Classification Rules of the Indian Register of Shipping.
- The craft is waterjet-propelled and carries lightweight torpedoes, indigenous rocket launchers and sonars for detecting and engaging underwater threats.
- It adds anti-submarine, coastal surveillance and mine-laying capability; the name revives INS Amini, a Petya III Class corvette decommissioned in 2002.
- The release puts indigenous content above 80 per cent and links the delivery to Aatmanirbhar Bharat and lower import dependence.
For Prelims
- ASW SWC: a class of small anti-submarine ships built for shallow coastal waters, where large frigates and destroyers operate poorly; the release lists anti-submarine, coastal surveillance and mine-laying roles.
- GRSE: Garden Reach Shipbuilders and Engineers, Kolkata, a defence public sector shipbuilder under the Ministry of Defence; it is building a batch of eight, whose fourth, Agray, was delivered on 30 March 2026.
- Cochin Shipyard Limited: builds the other batch of ASW SWC; INS Mangrol, third of its Mahe class, was commissioned on 12 October 2026 (PIB 2322494).
- Waterjet propulsion: a pump pushes water out through a nozzle instead of turning a propeller, giving high manoeuvrability in shallow and confined waters.
- Indian Register of Shipping: India's ship classification society, headquartered in Mumbai; a ship built to its Rules is surveyed against them during construction.
- Delivery versus commissioning: delivery is the builder's handover to the Navy; commissioning formally inducts the ship as an INS. Mangrol was delivered on 22 August and commissioned on 12 October 2026.
- Legacy names: the Navy reuses the names of retired ships; the first INS Amini was a Petya III Class anti-submarine corvette, a Soviet-origin design, decommissioned in 2002.
- Positive Indigenisation Lists: the Ministry of Defence has notified lists of items the services may buy only from Indian industry, the policy frame for indigenous-content claims.
For UPSC: Amini: ASW Shallow Water Craft built by GRSE, delivered 5 November 2026; over 80 per cent indigenous content; named for Amini Island, Lakshadweep; ex-INS Amini (Petya III, decommissioned 2002).
What it is NOT: The release does not say which unit in the GRSE series Amini is, when it will be commissioned or where it will be based. It gives no displacement, speed, endurance, sonar model or cost, and does not name the engines or waterjets. It claims over 80 per cent indigenous content without saying how that is measured or which systems are imported. No timeline for the remaining craft is given.

Anchor
The Navy needs ships that can find submarines close to the coast, where harbours, fishing grounds and cables lie. Amini adds one more such craft built at home.
Substantiation (data)
Amini was delivered on 5 November 2026 with over 80 per cent indigenous content. It carries lightweight torpedoes, indigenous rocket launchers and sonars. The fourth GRSE craft, Agray, came on 30 March 2026.
Position
Home-built shallow-water craft free larger ships for the open sea, give coastal surveillance and mine-laying capacity, and keep yards and small suppliers busy.
Counterpoint
The 80 per cent figure does not say which systems, such as engines, sonars or weapons, are still imported. Delivery is not commissioning, and the release gives no data on cost, delays or readiness.
Way forward
Publish how indigenous content is counted, bring engines and sonars under Indian supply, schedule crew training and base facilities with each delivery, and report the whole series' cost and timeline.
Conclusion
One more delivery is a small step in a long programme. The test is the whole series reaching the fleet on schedule with Indian sensors and engines.
