INS Arnala, the Indian Navy’s first indigenously designed and constructed Anti-Submarine Warfare Shallow Water Craft (ASW-SWC), marks a major milestone in India’s transition from a “Purchaser’s Navy” to a “Builder’s Navy”, highlighting the rising power of home shipbuilding below the Aatmanirbhar Bharat imaginative and prescient.INS Arnala is the lead ship of a brand new class of Anti-Submarine Warfare Shallow Water Craft designed for operations in coastal and shallow waters, the place detecting and monitoring hostile submarines is especially difficult.The vessel has been indigenously designed and constructed by Backyard Attain Shipbuilders & Engineers (GRSE) below a ministry of defence programme aimed toward strengthening India’s indigenous defence manufacturing ecosystem.Named after the historic Arnala Fort off Vasai in Maharashtra, the warship displays the Navy’s custom of linking its vessels with India’s maritime heritage. With greater than 80 per cent indigenous content material, the venture introduced collectively private and non-private sector companions, together with a large community of MSMEs supplying fight techniques, sensors and tools.
Launch, supply and commissioning
Arnala was launched on December 20, 2022, at Larsen & Toubro’s shipyard in Kattupalli close to Chennai.After in depth outfitting and sea trials, the ship was delivered to the Indian Navy and commissioned into the Japanese Naval Command at Naval Dockyard, Visakhapatnam, on June 18, 2025, within the presence of chief of defence employees basic Anil Chauhan.The ceremony was attended by senior naval officers, civilian dignitaries and representatives from GRSE and L&T, underlining its significance for indigenous naval functionality.
What’s INS Arnala?
Measuring about 77 metres in size with a displacement of round 1,490 tonnes, INS Arnala falls within the gentle corvette or shallow water combatant class, optimised for coastal missions and fast deployment.It’s the largest Indian naval warship powered by a diesel engine–waterjet propulsion system, enabling excessive manoeuvrability, fast acceleration and operations in shallow-draught waters near the coast. The design additionally incorporates stealth options to cut back radar, acoustic and infrared signatures, bettering survivability throughout anti-submarine operations in crowded littoral environments.The ship is designed for underwater surveillance, search and rescue (SAR) operations and Low Depth Maritime Operations (LIMO), alongside its main anti-submarine warfare function.Geared up with superior underwater sensors, mine-laying functionality and fashionable command-and-control techniques, INS Arnala can function independently or as a part of bigger naval job teams, contributing to sea lane surveillance, coastal safety and safety of high-value property.
From Patrons to Builders
As the primary vessel of the ASW SWC (GRSE) sequence, INS Arnala varieties a part of a broader effort to interchange ageing coastal ASW platforms and strengthen India’s maritime deterrence.Its excessive indigenous content material and public–personal building mannequin are anticipated to spice up the home business and deepen the Navy–business partnership for future warship growth.For India’s maritime technique, the induction of INS Arnala indicators rising confidence in home-grown design and fight techniques, reinforcing the nation’s ambition to construct a technologically superior, predominantly indigenous fleet whereas strengthening safety within the Indian Ocean Area.
