Analyze the economic and technological spillover effects of indigenous defence shipbuilding on India's industrial base.

Indigenous warship construction, epitomised by the Project 17A Nilgiri-class frigate INS Mahendragiri commissioned in July 2026, converts strategic spending into broad-based industrial capability. Analysing its spillovers requires separating economic multipliers from technological diffusion, before reassembling both as drivers of the industrial base.

Economic spillovers

• MSME ecosystem: Mahendragiri engaged over 200 MSMEs, generating ~4,000 direct and 10,000+ indirect jobs, seeding ancillary clusters around shipyards [1].
• Import substitution: over 75% indigenous content retains capital domestically and cuts forex outgo on foreign platforms, aligning with Aatmanirbhar Bharat [3].
• PSU capacity build-up: parallel orders across MDL (Mumbai) and GRSE (Kolkata) deepen order books and yard modernisation [1].
• Skilling & employment: sustained demand nurtures a specialised welding, metallurgy and marine-engineering workforce.

Technological spillovers

• Systems integration: absorbing BrahMos, MF-STAR radar, VL-SRSAM and the Integrated Platform Management System builds complex systems-engineering skill transferable to civil sectors [2].
• Design capability: in-house design by the Navy's Warship Design Bureau matures indigenous R&D and standards [1].
• Dual-use diffusion: advanced steel, automation, sensors and CODOG propulsion migrate to commercial shipping, electronics and heavy engineering [2].

Persisting gaps—imported gas turbines, propulsion and select sensors—show indigenisation remains incomplete. Nonetheless, indigenous shipbuilding acts as a technology-and-employment flywheel: each hull strengthens MSMEs, skills and R&D that outlast the vessel. Deepening a domestic marine-equipment supply chain, as envisaged under Aatmanirbhar Bharat [3], can convert these spillovers into an enduring, self-reliant industrial base.
