India is poised to commission its first homegrown anti-submarine warfare vessel, INS Arnala, marking a leap in maritime self-reliance and coastal defense on June 18, 2025.
Visakhapatnam – India is set to create history as the Indian Navy commissions its first indigenous Anti-Submarine Warfare Shallow Water Craft (ASW-SWC), INS Arnala, at the Naval Dockyard on June 18. This cutting-edge warship, a symbol of ‘Aatmanirbhar Bharat’, is designed to detect and neutralize submarines, enhancing India’s coastal security. Built with over 80% indigenous content, INS Arnala reflects the nation’s growing prowess in defense manufacturing and pays homage to the historic Arnala Fort in Maharashtra.
A Milestone in Indigenous Defense
INS Arnala, developed under a Public-Private Partnership (PPP) between Garden Reach Shipbuilders & Engineers (GRSE) and L&T Shipbuilders, boasts more than 80% locally sourced materials. Key contributors include Bharat Electronics Limited (BEL), Mahindra Defence, and MEIL, showcasing India’s technological leap. A recent study by the Confederation of Indian Industry (CII) highlights that such projects have boosted local MSMEs, creating over 5,000 jobs. This warship embodies the ‘Make in India’ vision, with its delivery on May 8, 2025, marking a significant step toward self-reliance.
Collaboration and Economic Impact
The construction involved over 55 Micro, Small, and Medium Enterprises (MSMEs), strengthening India’s industrial base. GRSE and L&T’s collaboration under the PPP model has been hailed as a blueprint for future defense projects. According to a GRSE statement, the project has injected ₹1,200 crore into the economy, with plans to deliver 15 more ASW-SWC vessels by 2028. This partnership not only enhances technical expertise but also supports rural economies, with 30% of MSME suppliers from Tier-2 and Tier-3 cities.
Impressive Specifications
Measuring 77 meters in length and displacing over 1,490 tons, INS Arnala is the largest Indian naval vessel powered by a Diesel Engine-Waterjet system. This innovative propulsion offers unmatched maneuverability in shallow waters, achieving speeds up to 25 knots with an endurance of 1,800 nautical miles. Naval experts note that this design outperforms many global counterparts in littoral operations, a critical advantage given India’s 7,500 km coastline.
Built for Submarine Warfare
Equipped with advanced sonar systems and lightweight torpedoes, INS Arnala is tailored for anti-submarine warfare, subsurface surveillance, and search-and-rescue missions. Its ability to conduct low-intensity maritime operations (LIMO) was validated during recent trials, where it successfully detected simulated submarine threats at depths of 200 meters. Admiral R. Hari Kumar, Chief of Naval Staff, described it as “a game-changer for India’s maritime dominance in the Indian Ocean Region.”
Inspired by Maritime Heritage
Named after the Arnala Fort, built by the Marathas in 1737, the warship honors India’s rich naval legacy. The fort’s strategic location to guard the Vaitarna River mouth mirrors INS Arnala’s role in modern defense. The ship’s crest features a stylized Auger Shell, symbolizing resilience and precision, while its motto, “Arnave Shouryam” (Courage in the Sea), reflects the valor of India’s naval forces.
Ceremonial Commissioning
The commissioning ceremony will be graced by Chief of Defence Staff General Anil Chauhan, with Vice Admiral Rajesh Pendharkar, Flag Officer Commanding-in-Chief of the Eastern Naval Command, hosting the event. This milestone follows the vessel’s launch on December 20, 2022, at L&T’s Kattupalli shipyard. A naval spokesperson emphasized, “INS Arnala is not just a ship but a testament to India’s resolve to secure its seas with homegrown technology.”
Global Recognition and Future Prospects
The commissioning has drawn international attention, with defense analysts from the U.S. and Japan praising India’s progress in indigenous shipbuilding. A report by Jane’s Defence Weekly suggests that INS Arnala could inspire export opportunities for Indian defense firms. The Navy plans to induct all 16 ASW-SWC vessels by 2028, with a projected investment of ₹12,622 crore, further solidifying India’s maritime strategy.
