Q. Examine how Aatmanirbhar Bharat in defence manufacturing is reshaping India's naval modernisation. (15 marks, 250-350 words)

Aatmanirbhar Bharat has moved the Indian Navy from an import-dependent "Buyer's Navy" to a "Builder's Navy", with warships now designed in-house by the Warship Design Bureau (WDB) and built in Indian yards [4]. The recent Nilgiri, Sandhayak and Arnala classes show how self-reliance is reshaping not just what the Navy buys, but how it fights and builds [1].

Indigenous design and construction capability - Project 17A Nilgiri-class stealth frigates are WDB-designed with reduced radar, thermal and acoustic signatures; INS Mahendragiri, the sixth of class, was commissioned in July 2026 with over 75% indigenous content [2]. - Six frigates inducted within roughly a year and a half marks a sharp improvement over the historical record of delays [2].

Building a balanced, full-spectrum fleet - Self-reliance now covers non-glamorous but critical roles: Sandhayak-class Survey Vessels (Large) restore hydrographic and nautical-charting capacity, cutting dependence on foreign seabed data [1]. - Arnala-class ASW Shallow Water Craft, with over 80% indigenous content, plug the littoral anti-submarine gap left by ageing Abhay-class corvettes [3].

Widening the industrial ecosystem - A multi-yard model — MDL and GRSE with private L&T Shipbuilding — spreads capacity across public and private sectors [3]. - Orders sustain MSME supply chains and skilled employment; the Indian Naval Indigenisation Plan (2015–2030) anchors this across "float, move, fight" categories [4].

Persisting gaps - Critical propulsion, sensors and weapon sub-systems still involve foreign content; indigenisation is deepest in "float", thinnest in "fight" [4].

Indigenisation has therefore shifted naval modernisation from episodic imports to a self-sustaining design-build cycle that underwrites strategic autonomy in the Indian Ocean Region. Deepening it — through sustained R&D in propulsion and sensors, assured order pipelines for private yards and MSMEs, and design-stage academia–industry partnership — would let India consolidate its stated ambition of becoming a leading maritime power and a credible net security provider.
