What Happened
- Garden Reach Shipbuilders and Engineers Ltd (GRSE), Kolkata, delivered three frontline naval platforms to the Indian Navy in a single day — a first-of-its-kind "triple delivery" achievement in Indian shipbuilding history.
- The three platforms are: (1) INS Dunagiri — the fifth ship of the Nilgiri Class (Project 17A) guided-missile frigates; (2) INS Sanshodhak — a Survey Vessel Large (SVL); and (3) INS Agray — the fourth ship of the Arnala Class anti-submarine warfare shallow water craft (ASW-SWC).
- With this delivery, GRSE has now built a total of 118 warships, including 80 delivered to the Indian Navy, reinforcing its status as one of India's premier defence shipyards.
- The Arnala Class ASW-SWC series has nearly 88% indigenous content — one of the highest localisation ratios in India's naval shipbuilding programme.
- The deliveries directly advance India's Aatmanirbhar Bharat vision in the defence sector and the Defence Acquisition Procedure (DAP) 2020's priority for indigenous procurement.

Garden Reach Shipbuilders and Engineers (GRSE) and Defence Shipbuilding
GRSE, headquartered in Kolkata, is a Mini Ratna Category-I CPSU under the Ministry of Defence and one of India's two major naval shipbuilders. It specialises in frontline warships, survey vessels, fast patrol vessels, and landing craft. GRSE builds platforms for the Indian Navy, Indian Coast Guard, and exports to friendly foreign navies.
- GRSE is building three of the seven Project 17A (Nilgiri Class) frigates — the other four are built by Mazagon Dock Shipbuilders (MDL), Mumbai.
- Contract for 8 Arnala Class ASW-SWC ships was signed between the Defence Ministry and GRSE on April 29, 2019, total contract value ~₹6,311 crore.
- GRSE received the Navratna status in 2024, reflecting its financial and operational performance.
- As of March 2026, GRSE has delivered 118 vessels total — 80 warships, with remaining including patrol vessels, fast attack craft, and export orders.
- GRSE has exported vessels to friendly navies including Bangladesh, Mauritius, and Sri Lanka.
Connection to this news: The triple delivery from a single yard in a single day demonstrates GRSE's enhanced production capacity and project management capability — a key marker of indigenous shipbuilding maturity under Aatmanirbhar Bharat.
Aatmanirbhar Bharat in Defence and the DAP 2020 Framework
Aatmanirbhar Bharat (Self-Reliant India) in defence, launched in 2020, mandates a phased approach to reducing defence imports and increasing domestic procurement. The Defence Acquisition Procedure (DAP) 2020 replaced the earlier DPP 2016 and introduced new categories prioritising indigenous design, development, and manufacturing.
- DAP 2020 procurement categories: IDDM (Indigenously Designed, Developed and Manufactured) is the highest priority; followed by Buy Indian (IDDM), Buy Indian, Buy and Make (Indian), Buy and Make, and Buy Global.
- Defence Indigenisation: India's defence exports have grown from ₹1,521 crore in FY2016-17 to over ₹21,000 crore in FY2024-25.
- Positive Indigenisation Lists (PIL): Ministry of Defence has issued four PILs banning import of 509+ items, including complex military platforms — naval vessels are on these lists.
- The iDEX (Innovations for Defence Excellence) and DTIS (Defence Testing Infrastructure Scheme) support the domestic defence ecosystem.
- Project 17A frigates are a "Buy Indian (IDDM)" category procurement under DAP — requiring high indigenous content.
Connection to this news: INS Dunagiri (Project 17A) and INS Agray (Arnala Class) are both products of India's indigenisation drive — built under domestic shipyards with high local content, directly fulfilling DAP 2020's IDDM mandate and demonstrating that complex warship construction is now firmly within India's industrial capability.
Project 17A (Nilgiri Class) Frigates: Capability Profile
Project 17A represents India's most advanced class of guided-missile frigates currently under construction. It is an evolved variant of the Shivalik-class (Project 17) frigates, with significantly enhanced stealth features, weapons fit, automation, and survivability.
- Total ships: 7 (4 at MDL Mumbai + 3 at GRSE Kolkata); Defence Acquisition Council cleared Project 17A at ₹45,000 crore.
- Role: Multi-mission — anti-surface warfare, anti-submarine warfare (ASW), anti-air warfare, and land attack.
- Stealth features: Reduced radar cross-section hull design, infrared suppression, acoustic quietening.
- Weapons: BrahMos supersonic cruise missiles, Barak-8 medium-range surface-to-air missiles, torpedo launch systems, 76mm OTO Melara gun.
- Indigenous content: Approximately 75% indigenous content, with sensors, weapons, and propulsion sourced domestically or under transfer of technology.
- Dunagiri is the 5th ship of the class; earlier ships include INS Nilgiri, Himgiri, Udaygiri, and Vindhyagiri.
Connection to this news: INS Dunagiri's delivery completes the near-full deployment of the first five Project 17A frigates — a significant enhancement to the Indian Navy's blue-water combat capability, particularly for operations in the Indian Ocean Region (IOR).
