Overview On 6 March 2026 , Raksha Mantri Shri Rajnath Singh inaugurated Sagar Sankalp in Kolkata. He linked global supply‑chain disruptions and heightened maritime activity to the need for Aatmanirbharta in defence, especially shipbuilding. Key Developments Target to place India among the top‑10 shipbuilding nations by 2030 and top‑5 by 2047. Domestic defence production crossed Rs 1.50 lakh crore in FY 2024‑25; exports reached ≈ Rs 24,000 crore and are projected to hit ≈ Rs 29,000 crore by April 2026 . Private sector’s share in defence platforms is about 25 % and is expected to rise to 50 % of total value. All warships and submarines on order for the Indian Navy are being built in Indian shipyards from design to life‑cycle support. Implementation of defence corridors , green‑channel certification, and opening of DPSU orders to private players. Investment of roughly Rs 3 lakh crore under Maritime India Vision 2030 and Maritime Amrit Kaal 2047 for modern shipbuilding clusters. Important Facts The government has emphasized turning shipyards like GRSE into technology hubs through digital design tools, modular construction, and integrated supply chains. Financial assistance schemes, liberalised FDI norms, and PPP models are being introduced to attract private investment. Operations such as Operation Sindoor showcase the Indian Navy’s readiness, reinforcing the narrative that a “Builder’s Navy” is now a reality rather than a slogan. UPSC Relevance GS 2 (Polity) : Understanding the role of the Defence Ministry, DPSUs, and policy reforms for self‑reliance. GS 3 (Economy) : Impact of defence exports on trade balance, FDI liberalisation, and the economic rationale behind defence corridors . GS 1 (History) : Continuity from the historic transition of the Indian Navy from a “Buyer’s Navy” to a “Builder’s Navy”. GS 4 (Ethics) : Public‑private partnership dynamics and the ethical dimension of self‑reliance versus strategic dependence. Way Forward To achieve the stated targets, the government must sustain: Robust R&D investment in high‑end defence technologies. Streamlined import‑export procedures and faster green‑channel clearances. Enhanced collaboration between DPSUs, MSMEs, start‑ups, and private shipbuilders. Continuous up‑skilling of the workforce to operate advanced digital and modular shipbuilding platforms. Successful implementation will not only secure India’s maritime interests but also position the country as a major global shipbuilding hub, contributing to strategic autonomy and economic growth.
