NEW DELHI : In a milestone that reshapes both India’s defence posture and its semiconductor ambitions, the Defence Research and Development Organisation (DRDO) has declared its indigenously developed Gallium Nitride (GaN) technology fully operational, closing a strategic capability gap that foreign suppliers once refused to bridge.
The announcement on January 25, 2026, marks the culmination of a decade-long effort that traces its origins to the 2016 Rafale fighter jet deal with France. At the time, India pushed hard for the transfer of GaN technology under the contract’s mandatory 50 percent offset clause. Paris declined, agreeing to supply advanced systems but withholding the core GaN fabrication process, citing export controls and the technology’s strategic sensitivity.
What was denied diplomatically became the spark for a high-stakes domestic technological gamble.
A Refusal That Changed Course
Senior officials involved in the Rafale negotiations recall that while France was willing to deliver state-of-the-art hardware, the “recipe” behind the semiconductor heart of modern radars and electronic warfare systems remained off-limits. For New Delhi, the choice was stark: accept long-term import dependence for a mission-critical technology, or attempt a high-risk indigenous breakthrough.
The government chose the latter.
DRDO entrusted the mission to two of its most advanced research hubs — the Solid State Physics Laboratory (SSPL), Delhi, and the Gallium Arsenide Enabling Technology Centre (GAETEC), Hyderabad. Their mandate went far beyond reverse engineering. India aimed to master the entire GaN technology cycle, from material growth and wafer fabrication to system-level integration.
From Concept to Combat-Ready
Progress was incremental and largely invisible to the public. By March 2023, DRDO scientists had achieved a critical breakthrough, successfully developing GaN-based Monolithic Microwave Integrated Circuits (MMICs) at the laboratory level. What followed was a rigorous multi-year phase of validation, reliability testing, and ruggedisation, ensuring the chips could withstand the extreme stresses of combat platforms.
That journey reached a decisive milestone this month with the unveiling of India’s first fully deployment-ready GaN MMIC. Measuring just a few millimetres across, the chip can handle exceptionally high power densities and ultra-fast switching speeds far beyond the limits of conventional silicon-based semiconductors, while operating reliably at temperatures approaching 1,000 degrees Celsius.
Defence officials describe the achievement as a quiet but transformative leap. “This is not a prototype anymore,” a senior DRDO scientist said. “This is a system-ready technology.”
Why GaN Redefines Modern Warfare
Gallium Nitride has emerged globally as the gold standard for high-power, high-frequency electronics. Compared to silicon, GaN enables power switching speeds up to 300 times faster, significantly higher voltage handling, and dramatically improved thermal resilience. These characteristics allow designers to build smaller, lighter, and more powerful systems without the burden of heavy cooling infrastructure.
For modern militaries, this translates directly into sharper radars, longer detection ranges, more effective electronic jammers, and compact, highly accurate missile seekers. A GaN-based radar module that once required bulky arrays can now be miniaturised without sacrificing performance, a decisive advantage for fighter aircraft, drones, and space platforms.
Strategic Independence Secured
With this breakthrough, India joins an elite group of nations — the United States, France, Russia, Germany, South Korea, and China — that possess end-to-end GaN technology under sovereign control.
The implications for the Indian Armed Forces are immediate and far-reaching. Indigenous GaN chips are slated to power the Uttam Mk2 AESA radar for the Tejas Mk2 fighter, the Virupaksha radar planned for the Su-30MKI upgrade programme, advanced electronic warfare suites, next-generation missile seekers, unmanned aerial vehicles (UAVs), and military satellites.
Crucially, full intellectual property (IP) ownership ensures that production lines cannot be disrupted by foreign political pressure during crises. Defence analysts describe this as a decisive shift from platform-level self-reliance to component-level sovereignty. “In wartime, no external supplier can switch us off,” one analyst noted. “That changes the calculus entirely.”
Economic and Industrial Ripple Effects
Beyond the battlefield, the GaN breakthrough carries major economic significance. The global GaN semiconductor market is projected to exceed $21 billion by 2031, driven by demand across defence, telecommunications, electric vehicles, and space systems.
DRDO has already begun transferring fabrication processes to Indian industry partners at a nominal cost, a move aimed at seeding a domestic GaN ecosystem. This approach is expected to push Indian companies beyond assembly and integration into high-value semiconductor manufacturing, aligning closely with the government’s Make in India and Atmanirbhar Bharat initiatives.
Industry executives see the development as a rare strategic opening. “Very few countries have cracked GaN independently,” said one semiconductor sector expert. “India now has a chance to compete not just as a buyer, but as a global supplier.”
Rewriting the Rafale Offset Story
What France declined to transfer under the Rafale deal has now been built indigenously, from the ground up. The episode has quietly rewritten the narrative of India’s defence procurement, transforming a high-profile refusal into a catalyst for technological self-confidence.
A decade after being told “no,” India has answered with a capability that places it among the world’s most advanced semiconductor powers — on its own terms, and under its own control.
