INS Arnala
GRSE delivered new Anti-Submarine Warfare Shallow Water Craft INS Arnala to the Indian Navy. This milestone enhances the Indian Navy’s capabilities in coastal defence against potential submarine threats. The vessel was launched as part of a contract signed in April 2019, which includes the construction of eight such crafts.
INS Arnala
INS Arnala measures 77.6 metres in length and 10.5 metres in width. It is designed for full-scale sub-surface surveillance and anti-submarine operations. The craft can operate in coordination with aircraft for enhanced maritime security. The vessel is built under a Public-Private Partnership (PPP) model, collaborating with L&T Kattupalli in Tamil Nadu.
Strategic Importance
Named after the historic Arnala island, the craft signifies India’s commitment to maritime security. The island has historical relevance, associated with Maratha king Chhatrapati Shivaji Maharaj. The ASW crafts will replace the older Abhay class ships, boosting India’s coastal defence capabilities.
Technical Specifications
The ASW shallow water crafts have a displacement of 900 tons and a maximum speed of 25 knots. They possess an operational endurance of 1,800 nautical miles. These specifications enable effective patrolling and surveillance in littoral waters, ensuring robust maritime security.
Indigenous Content
Over 80% of the ASW craft’s content is indigenous. This focus on local manufacturing aims to enhance self-reliance in defence production. It is expected to create job opportunities and develop technical expertise within the country.
Future Developments
GRSE is currently engaged in building 16 more warships, including advanced stealth frigates and offshore patrol vessels. This expansion reflects India’s growing naval capabilities and commitment to modernising its maritime forces.
