India's Naval Shipbuilding Programme
How Indian shipyards went from building small patrol vessels to aircraft carriers and stealth frigates
Imagine India's naval shipbuilding capability, covered under Ports & Shipping elsewhere on this site in its commercial dimension, applied to genuinely more technically demanding military vessels, Mazagon Dock Shipbuilders and Cochin Shipyard building the Kalvari-class submarines and INS Vikrant, India's first domestically built aircraft carrier, a genuine progression from decades of primarily foreign-built or foreign-licensed naval vessels toward increasingly indigenous warship design and construction.
The commissioning of INS Mahendragiri, an advanced stealth frigate with over 75 percent indigenous content, into the Indian Navy's Eastern Fleet in July 2026 illustrates exactly how far this indigenisation has progressed, a warship this sophisticated, stealth design, advanced sensors and weapons integration, being built with the substantial majority of its content sourced domestically represents a considerably deeper manufacturing achievement than simply assembling foreign-designed vessels under license.
This naval shipbuilding progress connects directly to the Positive Indigenisation List and Strategic Partnership Model frameworks covered elsewhere on this site, both specifically designed to push exactly this kind of domestic content growth across major defence platforms, naval vessels representing one of the most technically demanding categories to indigenise given the sheer complexity of integrating propulsion, weapons, sensor and stealth systems into a single seaworthy platform.
This shipbuilding capability matters directly for India's maritime strategic position covered under Ports & Shipping and broader regional security discussions elsewhere on this site, a navy capable of building its own sophisticated vessels domestically, rather than depending on foreign shipyards or licensed foreign designs, gains genuine strategic autonomy in naval force planning and modernisation timing, no longer constrained by foreign supplier availability, export licensing restrictions or geopolitical relationship changes that could otherwise affect access to critical naval platforms.
