Why this matters now
Defence self-reliance is a major GS-3 theme linking security, technology, manufacturing and the economy. Aspirants should know the policy tools driving it and the institutions (DRDO, DPSUs, private players) behind India’s shift from importer toward exporter.
The key policy tools
- Positive Indigenisation Lists — lists of items that can no longer be imported beyond set timelines (issued by the Department of Military Affairs and by DRDO/DPSUs for components), forcing domestic sourcing;
- Domestic procurement budget earmarking — a large share of the capital acquisition budget reserved for Indian industry;
- Defence Industrial Corridors in Uttar Pradesh and Tamil Nadu;
- iDEX (Innovations for Defence Excellence) — funding startups and MSMEs for defence innovation;
- FDI in defence raised (up to 74% via automatic route, higher with approval).
Who builds it
DRDO leads R&D (missiles, radars, systems); the Defence Public Sector Undertakings (HAL, BEL, BDL, the new ordnance-factory corporations, etc.) and a growing private sector (Tata, L&T, Adani, Bharat Forge and many MSMEs) manufacture platforms. Flagship indigenous systems include the Tejas fighter, BrahMos missile, the Arjun tank, the INS Vikrant aircraft carrier and a range of missiles and radars.
From importer to exporter
India’s defence exports have risen sharply (to record levels in the tens of thousands of crores) — exporting items like the BrahMos missile, patrol vessels, radars and components to many countries. The goal is a self-reliant defence-industrial ecosystem that meets domestic needs and competes globally, though India still imports key high-end platforms and engines.
UPSC angle
Know the policy levers (positive indigenisation lists, budget earmarking, corridors, iDEX, FDI) and the institutional mix (DRDO + DPSUs + private). Pair with record defence exports and flagship indigenous systems.
Frequently asked questions
What is a positive indigenisation list?
A list of defence items that cannot be imported beyond a set timeline, forcing the armed forces to source them domestically — a key tool for self-reliance.
Where are India’s defence corridors?
In Uttar Pradesh and Tamil Nadu, set up to cluster defence manufacturing.
What is iDEX?
Innovations for Defence Excellence — a scheme that funds startups and MSMEs to develop defence technologies.
Is India still an arms importer?
India remains a major importer of high-end platforms and engines, but indigenisation and record defence exports are steadily shifting the balance toward self-reliance.
