India’s defense electronics story is usually told in press releases. A radar gets tested, a missile gets certified, a minister cuts a ribbon at a new facility.
But buried within it is a far more uncomfortable truth: the highest-value, most operationally decisive components, the radars, the seekers, the electronic warfare suites, the avionics mission computers, remain overwhelmingly foreign.
What rarely gets examined is the plumbing beneath all of it: where the actual components come from, who owns the IP inside, and what happens if the phone stops getting answered in Tel Aviv or Moscow when things go sideways. That is the story worth telling.
For a country fighting a two-front deterrence problem across the Himalayas and the Indian Ocean simultaneously, that is not just an economic inconvenience. It is a strategic vulnerability of the first order.
Production Linked Incentive (PLI) schemes, now being extended and recalibrated toward defense electronics, are where New Delhi is placing its corrective bet.
The question worth examining is not whether PLI will generate investment. It already has.
By March 2025, PLI schemes across fourteen sectors had attracted over $21 billion in realized investment, generating $190.9 billion in production output.
The question is not whether PLI will generate factories. It will.
The question is whether it can generate the specific, technically irreducible capabilities that sit at the very top of the electronics pyramid and that no supplier will hand over voluntarily.
The Ugly Arithmetic of Import Dependency that Nobody Wants to Print
Start with the uncomfortable numbers. India imports roughly 60 to 65 percent of its defense equipment by value.
But that aggregate figure obscures something important: not all defense electronics are created equal.
A printed circuit board for a communications terminal is a fundamentally different manufacturing challenge than a Gallium Nitride transmit-receive module for an AESA radar.
Importing boots is not the same as importing the seekers inside your air-to-air missiles.
One you can replace with local leather.
The other requires years of RF engineering, signal processing software, and materials qualification to replicate, assuming anyone will teach you how.
These are the capabilities that sit at the apex of the technology pyramid, and they are precisely what India lacks indigenously at scale.

The GaN number at the top is the one that should concern every Indian strategic planner. Gallium Nitride is to modern radar and electronic warfare what silicon was to computing in the 1980s.
AESA radars depend on GaN-based transmit-receive modules for their power efficiency, their resistance to jamming, and their reliability under thermal stress.
China has aggressively indigenized GaN production. The United States tightly controls GaN exports under ITAR and EAR.
India currently imports the vast majority of its GaN components, and even the most promising domestic efforts: including iDEX’s contract covering GaN semiconductors; remain years away from production-qualified yield rates at military specification.
Why the Hardest Stuff Is the Most Important Stuff
There is a tempting narrative that India has already “solved” defense electronics. The Uttam radar exists. The Astra missile flies. Tejas Mk1A is in production.
That narrative confuses prototype-level achievement with industrial-scale sovereignty, and it is dangerously misleading.
A prototype that works in a test environment and a production line that delivers qualified hardware consistently at scale are separated by years of process engineering, yield improvement, supplier qualification, and certification work. India has the first.
It is building toward the second. PLI is the lever designed to close that gap faster.
The structural problem is that defense electronics is not a monolithic industry. It is a layered stack – raw materials, wafers, components, sub-assemblies, systems, software and a dependency at any layer propagates upward through everything above it.
India can assemble a radar without owning the semiconductor inside it, but that assembly is only as sovereign as the supply of the chip.
PLI schemes that operate only at the system level (the top of the stack) do not solve the dependency. They paper over it with a domestic nameplate.
The Supplier Web India Does Not Draw Publicly
Line weight = relative supply volume. Dashed = politically fragile or export-controlled. Green (DRDO/BEL) is the single fully sovereign supply relationship India currently holds.
Look at that diagram geometrically. India sits at the center of five external supply relationships, and only one — the DRDO/BEL line — is fully under its own political control.
The thickest commercially active line runs through Israel, which has become the single most important supplier of operationally current EW and seeker technology.
The American line carries the most strategically critical components but is also the most legally restricted.
The Russian line, once substantial, has become structurally unreliable in ways that the Ukraine war made permanent rather than temporary.
France and Europe supply the Rafale ecosystem but remain outside India’s control in any crisis.
PLI’s job is to build a sixth line – a genuinely sovereign domestic one – thick enough to eventually replace the others for the most critical applications.
The Ecosystem That Doesn’t Build Itself
Getting from “India needs indigenous EW systems” to “India has a functioning EW industrial base” is not a straight line. It moves through five distinct stages, each with its own specific bottlenecks, and skipping any of them almost always fails.
India is stuck between Stages 2 and 3 for most priority electronics categories. The prototype is done. The transfer is partial and slow.
The components are still coming from abroad. PLI operates most effectively at Stage 3 – the component supply chain – and that is precisely where the March 2025 scheme is pointed.
The alignment is better than it appears from outside.
But Stage 2’s broken technology transfer pipeline continues to throttle progress regardless of how much money flows into Stage 3, because you cannot manufacture what has not been transferred in manufacturable form.
The tech transfer problem is institutional, not financial. DRDO scientists are not incentivized to produce designs that a factory can absorb without extensive re-engineering.
HAL and BEL receive those designs but lack the process engineering workforce to translate them into production. Private firms face classification barriers that limit what they are even permitted to receive.
No PLI scheme fixes any of that. It requires a parallel institutional reform program that is considerably less photogenic than a factory opening.
The Doctrine Connection Most Analysts Are Skipping
Electronic warfare is not a supplementary capability you add to a force after sorting out the platforms. It is the enabling layer without which platforms become targets.
The lesson from Armenia-Azerbaijan, from Ukraine, from every contested airspace engagement since 2020, points toward the same conclusion: electromagnetic spectrum dominance in the opening hours of a conflict determines whether your fighters arrive at the target or become the target.
India’s two-front problem makes this especially acute. China operates a deeply integrated EW architecture along the LAC, regularly updated with lessons absorbed from observing other conflicts.
Pakistan has been selectively acquiring Turkish KORAL electronic warfare systems and Chinese ground-based jamming platforms calibrated against known Indian radar frequencies.
Neither threat is static. Both are being actively upgraded.
An India that builds indigenous EW suites — with full visibility into the software-defined jamming algorithms and the threat library management software — is an India with genuine operational sovereignty over its own electronic battlefield.
An India that assembles imported jammers under license is an India whose EW capability can be shaped, constrained, and in extremis withheld by supplier politics.
Export license conditions on defense electronics regularly include end-use restrictions governing where and how systems can be employed in real conflict.
That is not hypothetical. It is standard practice in every bilateral defense relationship India has.
This doctrinal argument is the one that PLI advocates should be making loudly, and largely are not. The economic case for indigenization is defensible but not compelling on its own.
The strategic sovereignty case – that a country cannot plan confidently around a capability it does not own – is far more urgent, and it is the argument that should be driving the speed and depth of the PLI investment.
Who Adjusts, and How
The beneficiaries of a successful PLI push in defense electronics are fairly predictable: Bharat Electronics Limited, Data Patterns, Astra Microwave, MTAR Technologies, and a second tier of private firms quietly building RF engineering and embedded systems capability.
The Uttam AESA radar, now significantly indigenized with technology transfer from DRDO to HAL, is planned for integration into Tejas Mk1A and future programs.
BEL stands as the primary production house, but the broader intent is to build a competitive private-sector ecosystem alongside the public incumbents.
The adjustment is most consequential for Israel. Israel Aerospace Industries and Elbit Systems have been central suppliers for India’s EW and avionics requirements for over two decades.
A successful PLI-driven indigenization program does not eliminate Israeli defense cooperation – that relationship has too many layers for a single policy lever to unwind – but it does shift the dynamic from dependency to selective partnership.
In contract negotiations, technology transfer discussions, and crisis-period supply decisions, that is a meaningfully different position for India to occupy.
Russia is the harder case and the more pressing one. Su-30MKI avionics remain heavily Russian, and the Ukraine war demonstrated with uncomfortable clarity what happens to maintenance supply chains when geopolitical conditions shift rapidly.
India is still issuing Requests for Information for Su-30 self-protection jammers, which reveals the depth of that legacy dependency.
PLI can accelerate the path off Russian avionics, but only if the incentive structure rewards the genuinely difficult work of integrating new indigenous systems into certified Russian-origin airframes – which is as much a regulatory problem as a manufacturing one.
The Budget Picture, Plainly Laid Out

The projected crossover — where domestic investment compresses the import bill – does not happen automatically.
It requires the PLI money to flow toward capability-building rather than assembly, and it requires the institutional reforms around technology transfer and certification to keep pace.
Without those, you get rising investment numbers and a flat import line, which is exactly what India’s defense sector has produced for most of the last decade.
The Regional Ripple: What the Neighbors Are Watching
China’s immediate reaction to India’s defense electronics indigenization drive is not alarm. It is patient observation.
Beijing understands that the gap between announced intention and operational capability in India’s defense sector is historically wide.
What it watches for is the inflection point: the moment when a private Indian firm demonstrates GaN T/R module production at military-qualified yield rates, or when DRDO’s EW laboratory delivers a software-defined jammer that matches Israeli performance parameters.
That inflection point, when it arrives, directly changes the electronic warfare balance along the LAC in ways that affect Chinese operational planning.
Australia and Japan are watching the semiconductor dimension. QUAD technology cooperation has been building toward trusted supply chains for defense-critical components.
A PLI-backed GaN manufacturing capability in India would not simply serve Indian requirements – it would qualify India as a contributor to a broader Indo-Pacific semiconductor architecture.
That is a fundamentally different strategic conversation than where India sits today as a net consumer of other people’s foundry output.
For Southeast Asian partners – Vietnam, Indonesia, the Philippines – the signal is different but equally significant. India has been positioning itself as an alternative defense supplier. BrahMos has established the template.
A credible domestic radar and EW production base, backed by PLI-scale incentives, opens the pathway to exporting sensor systems into a region actively diversifying away from single-country dependence.
That is a long game, but it starts with building the industrial base today.
The Three Scenarios Over the Next Five Years
PLI defense electronics: realistic scenarios to 2030
Optimistic — GaN breaks through 30% probability
A PLI-backed firm qualifies GaN T/R module production by 2027. Uttam radar reaches 85%+ indigenous content. BVR seeker production scales under RCI Hyderabad. India begins exploring defense electronics exports to Gulf and SEA markets by 2029. QUAD supply chain contribution becomes real, not aspirational.
Requires: GaN foundry investment, CEMILAC pipeline reform, sustained long-term procurement commitments to de-risk private capital.
—————————————————————————————————————————–
Base case — Incremental progress, persistent gaps 50% probability
Avionics and ground radar reach 75–80% indigenous content by 2028. Airborne EW lags two to three years behind. GaN dependency persists but is partially mitigated via QUAD-linked supply agreements with the US and Japan. Private sector grows but remains second tier to BEL and HAL in volume and certification depth.
Requires: Current trajectory maintained. No major institutional reform needed, but no major setbacks either.
—————————————————————————————————————————–
Pessimistic — PLI captures assembly, not technology 20% probability
Incentives are captured by firms assembling foreign components under Indian nameplates. The technology transfer bottleneck remains unaddressed. Import bill stays high. GaN gap widens as Chinese capability accelerates well beyond current levels. Crisis supply chain vulnerability remains structurally unchanged.
Risk factors: Weak IP enforcement, slow DRDO transfer culture, insufficient CEMILAC capacity, procurement short-termism rewarding price over indigenous content depth.
—————————————————————————————————————————–
Scenario probabilities are the author's independent assessment based on current program trajectories, institutional track record, and policy signal analysis.
The base case is not a failure – it represents genuine, compounding progress across avionics and ground systems.
But it also leaves India perpetually dependent on foreign suppliers for the hardest and most operationally decisive technologies: GaN semiconductors, advanced EW algorithm libraries, airborne self-protection systems capable of operating effectively against current-generation Chinese and Pakistani threats.
Base case India is more resilient than today’s India. It is not a sovereign India.
The pessimistic scenario is the one that keeps institutional reformers awake. India’s defense industrial history has a recurring pattern: well-designed incentive programs that get exploited at the margin rather than the center.
Firms learn quickly how to satisfy the letter of indigenization requirements while sourcing the critical technology from abroad.
PLI’s design must specifically and aggressively close that loophole – through indigenous content verification, IP ownership criteria, and production qualification standards that reward depth, not declarations.
What Most Analysts Are Getting Wrong
The mainstream commentary on India’s defense electronics PLI swings between two positions. The optimists count announcements.
The pessimists count delays. Both camps are missing the structural shift that is actually happening: the private sector’s perception of defense electronics as a viable long-term business is changing, and that change is difficult to reverse once it takes hold.
Data Patterns went from a small avionics components supplier to a publicly listed firm with a credible defense electronics order book. Astra Microwave has built a legitimate position in radar sub-assemblies.
A cohort of iDEX-backed startups has demonstrated genuine technical capability in EW signal processing and embedded RF systems. This is not yet an industrial ecosystem.
It is the beginning of one, and beginnings in deep technology industries are genuinely difficult to create and surprisingly fast to compound once they are established.
The question PLI is actually answering is not “can India design these things” – the answer to that has been yes for a decade.
The question is whether India can build them commercially, at production scale, with consistent quality, and at a price that makes defense procurement genuinely prefer the domestic option over the imported one. That is a much harder problem. PLI is the right instrument for it.
Whether it is designed with enough precision and followed up with enough institutional seriousness is the only question that still matters.
The Sensor Bet, Plainly Said
There is a version of this story where PLI works as intended: factories are built, component supply chains are developed, Indian nameplates appear on systems with genuinely high indigenous content, and the import bill for defense electronics begins a sustained decline.
There is another version where PLI does what industrial policy in India has sometimes done: generate impressive statistics around activity that does not move the capability needle.
PLI-Driven Defense Electronics: Projected Indigenous Content Growth (2024–2030)
The difference between those two versions is not primarily technical. India’s engineers can build this — that much is no longer in dispute.
The difference is institutional.
Does DRDO transfer technology in forms that industry can absorb?
Does CEMILAC process certifications fast enough to make production investment worthwhile?
Does procurement policy reward genuine indigenous content depth, or just nominal compliance?
Does a private firm building GaN T/R modules get treated as a strategic national asset, or as another vendor in a price negotiation?
None of those questions have clean answers yet.
But they are the only questions that matter for whether PLI in military electronics produces sensors – or produces paperwork.
And India’s threat environment, on both its active frontiers, does not offer the luxury of a slow answer.
“The capability India builds in its electronics workshops over the next five years will matter more to the outcome of a Himalayan contingency than almost any platform procurement decision currently on the table.”
