Kattupalli [Tamil Nadu]: Garden Reach Shipbuilders and Engineers (GRSE), Kolkata, has delivered the indigenously designed and constructed Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) INS Amini to the Indian Navy at Kattupalli, Tamil Nadu, on November 5, 2026. The vessel is the fifth of eight ASW-SWCs being built by GRSE under the Navy's programme to strengthen coastal anti-submarine warfare and underwater surveillance capabilities.

Designed specifically for operations in shallow coastal waters, Amini can undertake sub-surface surveillance, search and attack missions, and coordinated anti-submarine warfare operations alongside naval aircraft. The vessel is equipped with lightweight torpedoes, indigenous anti-submarine rocket launchers and advanced sonar systems to detect, track and engage underwater threats.
Measuring approximately 77.6 metres in length, the vessel has a shallow draught of around 2.7 metres, enabling it to operate effectively in littoral waters. Its propulsion system combines marine diesel engines with waterjets, providing enhanced manoeuvrability in coastal environments. It also carries an advanced Combat Management System and an indigenously manufactured 30 mm naval gun.
Amini features over 80 per cent indigenous content, reflecting the growing role of domestic shipyards and Indian defence suppliers in naval platform construction. The vessel is named after Amini Island in Lakshadweep and revived the legacy of the earlier INS Amini, a Petya III-class anti-submarine warfare corvette decommissioned in 2002.
The delivery strengthened the Navy's ability to monitor underwater activity and protect ports, harbours and coastal installations against submarine threats. It also marked another milestone in GRSE's contribution to India's indigenous warship-building programme under the Aatmanirbhar Bharat initiative.
