What happened?
The Indian Navy is set to commission INS Arnala, the country’s first indigenously designed and built Anti-Submarine Warfare Shallow Water Craft (ASW SWC), at Visakhapatnam dockyard on Wednesday (June 18, 2025) under the Eastern Naval Command. Named after the historic fort ‘Arnala’ off Vasai, Maharashtra, the 77-meter-long warship is the largest Indian Naval warship propelled by a Diesel Engine-Waterjet combination. Designed and built by Garden Reach Shipbuilders and Engineers (GRSE), Kolkata, Arnala was delivered to the Indian Navy on May 8 (unspecified year in news source, but previous to June 18, 2025) at M/s L&T Shipyard, Kattupalli. Its construction involved a Public-Private Partnership (PPP) of GRSE with M/s L&T Shipyard, demonstrating the success of collaborative defence manufacturing. The ship is designed for underwater surveillance, search and rescue operations, Low Intensity Maritime Operations (LIMO), and is capable of undertaking ASW operations in coastal waters along with advanced mine-laying capabilities. It boasts over 80% indigenous content.
Why it matters to India
The commissioning of INS Arnala marks a significant milestone for the Indian Navy and its pursuit of indigenous shipbuilding, directly contributing to the government’s ‘Aatmanirbhar Bharat’ (self-reliant India) vision. With over 80% indigenous content, this warship reduces India’s dependence on foreign suppliers for critical defence equipment, bolstering its domestic manufacturing capabilities. The induction of ASW SWC ships like Arnala will significantly boost the Indian Navy’s shallow water Anti-Submarine Warfare capabilities, enhancing its operational readiness and maritime security along India’s vast coastline. This development reinforces India’s strategic autonomy in defence, supports the modernization of its naval fleet, and showcases the success of collaborative defence manufacturing models within the country.
