Discuss how indigenous warship-building programmes like Project 17A reflect India's progress toward self-reliance in defence manufacturing. What challenges remain in achieving full indigenisation?

India remains among the world's largest arms importers, making indigenous platforms central to Aatmanirbhar Bharat in defence. The Project 17A (Nilgiri-class) stealth frigate programme—capped by INS Mahendragiri's commissioning at Visakhapatnam in July 2026—signals a maturing warship-building ecosystem, even as full indigenisation remains work-in-progress [1].

Progress toward self-reliance

• Indigenous design & content: designed in-house by the Navy's Warship Design Bureau, with over 75% indigenous content [1].
• Domestic yard capacity: seven ships built across two PSUs—MDL (Mumbai) and GRSE (Kolkata)—with six delivered in ~1.5 years, showing accelerated execution [1].
• Ecosystem multiplier: integration of home-grown systems (BrahMos, indigenous fire-control and platform-management systems) and participation of 200+ MSMEs, generating employment and import substitution [2].
• Strategic dividend: extends India's blue-water reach in the Indian Ocean Region, reinforcing its "preferred security partner" role [1].

Challenges remaining

• Critical-technology gap: gas turbines, key sensors and some weapon sub-systems still rely on foreign collaboration—the last ~25% is the hardest.
• Time and cost overruns: complex warship projects face schedule slippages, raising life-cycle costs.
• Design-to-scale bottlenecks: limited yard throughput and a thin private-sector defence-shipbuilding base.
• R&D depth: propulsion, marine engines and advanced materials need sustained investment.

Project 17A demonstrates that indigenous naval design and construction have crossed a decisive threshold. Deepening R&D, expanding private participation and indigenising critical sub-systems—aligned with the Positive Indigenisation Lists—can convert this momentum into genuine strategic autonomy.
