India's Semiconductor Sovereignty: A Turning Point in Military Autonomy

India's Semiconductor Sovereignty: A Turning Point in Military Autonomy

India's military might has long been dependent on its ability to control its semiconductor supply chain. Every AI-enabled system, AESA radar, and encrypted communication link relies on a component that India imports 90-95% of: the semiconductor chip. However, what happens when that supply chain is threatened? The answer lies in India's refusal to accept a strategic vulnerability.

In 2016, during Rafale negotiations, India pushed for the transfer of Gallium Nitride (GaN) technology under the contract's mandatory 50% offset clause. Paris declined, citing export controls and the technology's strategic sensitivity. France was willing to deliver state-of-the-art hardware, but the 'recipe' behind the semiconductor heart of modern radars and electronic warfare systems remained off-limits.

Undeterred, the Defence Research and Development Organisation (DRDO) took on the challenge. By March 2023, DRDO had produced GaN-based Monolithic Microwave Integrated Circuits (MMICs), marking a significant milestone in India's semiconductor development journey. And by January 2026, its indigenous GaN technology was declared fully operational, making India one of only seven nations with end-to-end sovereign GaN capability.

But that's not all - Indian startup FermionIC Design has developed GaN-based chips for the Transmit-Receive Modules (TRMs) of the Virupaksha AESA radar, a game-changer in fighter radar technology. With approximately 2,400 TRMs, Virupaksha is among the most powerful fighter radars under development globally. This is not a laboratory curiosity; these chips have undergone rigorous validation meeting or exceeding performance benchmarks typically associated with Tier-1 global semiconductor suppliers.

India's semiconductor sovereignty is no longer a distant dream, but a rapidly unfolding reality. The strategic implications extend beyond performance. Using Indian-designed chips eliminates the risk of hidden vulnerabilities, backdoors, or external supply chain compromises. It ensures that sensitive mission data, targeting information, and real-time battlefield updates remain fully under national control.

As one analyst noted, 'In wartime, no external supplier can switch us off. That changes the calculus entirely.' Parallel to the GaN programme, India is building an indigenous processor ecosystem on the open-source RISC-V architecture, which requires zero licensing fees and offers complete design freedom. C-DAC launched DHRUV64 (VEGA AS2161) - India's first fully indigenous 64-bit microprocessor, designed for 5G, automotive, IoT, and defence applications.

The Cabinet approved ₹1.27 lakh crore for Semicon Mission 2.0 in July 2026, with provisions to incentivise even suppliers of raw materials - minerals and gases - in the chip manufacturing chain. A CLAWS analysis published in July 2026 flagged a deeper risk: India's growing use of military AI systems built on foreign semiconductor and cloud infrastructure creates structural vulnerabilities that could compromise long-term military autonomy.

Despite design breakthroughs, India still has no operational semiconductor fabrication facility producing advanced chips. The Tata Electronics fab in Dholera, Gujarat (₹91,000 crore investment) is under construction. Micron's ATMP facility in Sanand is being built. Renesas's OSAT facility is operational at pilot scale, with first chips expected mid-2026. But the gap between designing a chip and manufacturing it at scale is enormous.

India's NITI Aayog report explicitly identifies the need for 'secure fabs and packaging lines with air-gapped networks and controlled supply chains' for 'defence, aerospace and strategic infrastructure chips' including radiation-hardened, high-reliability, and tamper-resistant devices. These are not commercial fabs; they are dedicated, classified facilities that do not yet exist in India.

What France refused to transfer under the Rafale deal has now been built from scratch. India's semiconductor sovereignty is no longer a distant dream, but a rapidly unfolding reality. The country's military autonomy is poised to take a significant leap forward, as it moves closer to a fully sovereign supply chain for advanced military electronics.
