New Delhi: INS Arnala — the Indian Navy’s first indigenously designed and built Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) — has been commissioned into service, marking a critical milestone in India’s journey toward maritime self-reliance and strategic naval strength.
This new warship, constructed by Garden Reach Shipbuilders & Engineers (GRSE) in collaboration with L&T Shipyard, reflects India’s evolving defence capabilities under the Aatmanirbhar Bharat initiative.
The commissioning ceremony at the Naval Dockyard in Visakhapatnam was presided over by Chief of Defence Staff Gen Anil Chauhan, highlighting the vessel’s role in strengthening India’s coastal and littoral defence posture. With over 80 % indigenous content, INS Arnala stands as a testament to domestic engineering excellence and the nation’s transition from a “Buyer’s Navy” to a “Builder’s Navy.”
What is INS Arnala?
INS Arnala is the lead ship of a new class of shallow-water anti-submarine warfare vessels designed specifically for near-shore defence and surveillance.
It is the first ASW-SWC to be indigenously developed and delivered to the Indian Navy as part of a set of eight ships under this programme.
- Built by: Garden Reach Shipbuilders & Engineers (GRSE) with L&T Shipyard
- Delivered to Navy: 8 May 2025
- Commissioned: 18 June 2025 at Visakhapatnam
- Length: ~77 metres
- Propulsion: Diesel engine with water-jet combination — making it the largest Indian naval warship propelled by such a system
The vessel is named after the historic Arnala Fort off the coast of Vasai, Maharashtra — a nod to India’s rich maritime heritage.
What is the Significance of INS Arnala
Strengthening Coastal Defence: INS Arnala significantly enhances India’s ability to monitor and counter submarine threats in shallow waters — a domain where larger vessels are less effective. Its primary roles include:
- Anti-Submarine Warfare (ASW)
- Underwater Surveillance
- Search and Rescue (SAR)
- Low Intensity Maritime Operations (LIMO)
- Advanced Mine-Laying
These capabilities are vital for safeguarding India’s vast coastline and protecting crucial sea lanes in its maritime neighbourhood.
Indigenous Design — A Milestone for ‘Aatmanirbhar Bharat’
One of the most noteworthy aspects of INS Arnala is its domestic content — over 80 % of its components are made in India, including advanced sensors, combat systems, and propulsion systems supplied by local industry partners.
This achievement underscores India’s evolving defence manufacturing ecosystem and reinforces national goals of reducing dependency on foreign supplies in strategic sectors. The ship’s development showcases successful public-private partnerships (PPP) between GRSE and L&T Shipyard, a model likely to shape future defence projects.
A Larger Vision: Maritime Power and Self-Reliance
INS Arnala’s induction is part of India’s broader plan to bolster its presence in the Indian Ocean Region (IOR) — a strategically important maritime domain influenced by global naval powers. By expanding its fleet with indigenously built assets, the Indian Navy is enhancing deterrence against potential threats, securing vital trade routes, and asserting maritime authority in the region.
This aligns with India’s larger “Make in India” and Aatmanirbhar Bharat defence initiatives that aim to elevate domestic manufacturing and technological capability across strategic industries.
The Path Ahead
As additional ASW-SWC vessels in the Arnala class are delivered and commissioned over the next few years, the Indian Navy’s capacity for littoral defence and underwater combat will steadily expand. Together with other indigenous warships and submarines under construction, INS Arnala is a symbol of a more resilient, capable, and self-reliant maritime force.
