CHENNAI — In the modern theater of war, the lethality of a missile is no longer measured solely by the chemistry of its warhead or the thrust of its engine. Instead, victory is increasingly determined by the microscopic circuits etched onto silicon wafers. At the "SRM Presents The Hindu Semiconductor Summit 2026," India’s leading defense scientists issued a stark warning: despite the nation’s growing prowess in building world-class platforms like the BrahMos missile and the Sudarshan Chakra air defense shield, a fundamental vulnerability remains. As long as the semiconductors powering these systems are imported, India’s strategic autonomy remains on borrowed time.
Senior scientists and former chiefs of India’s premier defense organizations called for an immediate, "end-to-end" indigenization of the semiconductor ecosystem—spanning design, fabrication, testing, and packaging—to ensure that the "brains" of India’s weaponry are not compromised by foreign interests or supply chain weaponization.
Main Facts: The Vulnerability of Network-Centric Warfare
The core of the discussion centered on the shift from "platform-centric" warfare to "network-centric" operations. In the past, the strength of an army was judged by its tanks, ships, and aircraft. Today, it is judged by how well these platforms communicate and process data.
The Semiconductor Heart of Modern Weapons
Dr. V.K. Saraswat, former Director General of the Defence Research and Development Organisation (DRDO), emphasized that semiconductors are the bedrock of command, control, and communications. He noted that India is now "more or less equipped with complete network-centric capability," citing "Operation Sindoor" as a milestone. However, this capability is built on a fragile foundation of imported hardware.
The proposed Sudarshan Chakra, a multi-layer, multi-domain air defense system, represents the pinnacle of this shift. Designed to fuse data from satellite, sea, air, and land-based sensors using Artificial Intelligence (AI), the system is intended to provide a comprehensive shield over Indian skies. Yet, Dr. Saraswat warned that the sheer volume of data required to counter "saturation attacks"—where hundreds or thousands of drone swarms arrive simultaneously—requires processing power that India cannot yet manufacture domestically.
Precision and Processing Power
Dr. A. Sivathanu Pillai, the founder and former CEO of BrahMos Aerospace, illustrated the role of chips through the lens of precision. A BrahMos supersonic cruise missile can receive target coordinates and adjust its course within milliseconds to achieve a "bullseye hit."
"How has the intelligence come to that? It is a processor and the software," Dr. Pillai remarked. He provided a staggering comparison: the upcoming Light Combat Aircraft (LCA) Mark 2 can process as much data on a single mission as the entire MiG-21 fleet processed during the 1971 war. Even the historic success of Chandrayaan-3, India’s lunar mission, relied on semiconductor systems that were entirely imported—a fact Dr. Pillai identified as a persistent "problem" for national security.
Chronology: A History of Sanctions and Stagnation
To understand India’s current predicament, the panel traced the history of semiconductor development in the country, highlighting a series of missed opportunities and external roadblocks.
The 1980s: The Great Divergence
In the 1980s, India was actually ahead of many of its Asian peers. Professor Deleep Nair of IIT Madras pointed out that India received Complementary Metal-Oxide-Semiconductor (CMOS) technology from the Radio Corporation of America (RCA) before Taiwan did. However, while Taiwan nurtured TSMC into a global titan, India’s primary facility, the Semiconductor Complex Limited (SCL) in Chandigarh, suffered a devastating fire in the late 1980s and remained shut for a prolonged period.
The Sanctions Era
The vulnerability of depending on foreign chips is not theoretical; it is historical. Dr. Saraswat recalled how the Integrated Guided Missile Development Programme (IGMDP) was hampered when the United States and its allies curtailed the supply of 8086 and 8087 processors used in the first Prithvi missiles. This blockade intensified under the Missile Technology Control Regime (MTCR), forcing Indian scientists to innovate under extreme duress.
The Present Gap
Today, the leading-edge technology running at SCL Chandigarh is 180 nanometers (nm). To put this in perspective, this is the same technology level that companies like Intel, AMD, and IBM were using in the mid-1990s. While the world has moved to 3nm and is eyeing 2nm nodes, India’s defense systems are largely reliant on 28nm chips sourced from abroad.
Supporting Data: The Nanometer Race
The technical divide between India and the global leaders is stark, and the panel provided data points to illustrate the urgency of the situation.
- Node Disparity: Most Indian defense systems currently run on 28nm chips. The global standard for high-end AI and hypersonic systems is moving toward 3nm.
- The 2030-35 Target: The Indian government has set a target to achieve 3nm manufacturing capability by 2030–2035. Dr. Pillai warned that this is "too late," as the global landscape will have shifted again by then.
- Design vs. Fabrication: India currently accounts for 20% of the world’s chip design capability. However, almost all these designs are sent to foundries in Taiwan, South Korea, or the US for fabrication.
- The EUV Hurdle: To manufacture at advanced nodes (sub-7nm), Extreme Ultraviolet (EUV) lithography equipment is required. The current waiting list for this equipment from ASML (the sole global supplier) is four to five years.
- Human Capital: China’s lead in the sector is attributed to decades of sustained investment (since the 1980s) and a concerted effort to bring back Chinese-origin engineers trained in US foundries—a model India is only now beginning to emulate through the India Semiconductor Mission.
Official Responses: The Path Toward "Atmanirbharta"
The panel served as both a critique of past delays and a roadmap for future policy. The experts called for a shift in how the India Semiconductor Mission (ISM) is executed.
The "End-to-End" Mandate
The scientists argued that "Atmanirbharta" (self-reliance) cannot be achieved by merely setting up assembly plants. India must control the entire value chain:
- Materials: Identifying and stockpiling critical minerals like Gallium and Germanium.
- Design: Leveraging the existing 20% global design share and aiming for 50%.
- Manufacturing: Building indigenous foundries and the equipment needed to run them.
- Packaging: Developing domestic Outsourced Semiconductor Assembly and Test (OSAT) facilities.
The University Model
Dr. Saraswat and Dr. Pillai advocated for the creation of R&D "fabs" within IITs and other top universities, modeled after Belgium’s IMEC (Interuniversity Microelectronics Centre). They argued that without university-led research into next-generation technologies like neuromorphic chips (which mimic the human brain), India would remain a generation behind.
Current Progress
Prof. Deleep Nair noted some positive momentum. The Tata fab in Gujarat, being established with technology licensing from Taiwan’s PSMC, is expected to bring the 40nm node to India. While not "cutting edge" by smartphone standards, 40nm is a workhorse node for many automotive and industrial defense applications. Additionally, the DRDO’s Gallium Arsenide Enabling Technology Centre (GAETEC) is making strides in compound semiconductors like Gallium Nitride (GaN), which are essential for high-frequency radar systems.
Implications: The Risks of the "Hardware Trojan"
The most chilling segment of the summit dealt with the security implications of imported silicon. In a world of "cyber-kinetic" warfare, a chip can be a weapon used against its owner.
The Stuxnet Precedent
Dr. Saraswat cited the Stuxnet incident, where a flaw introduced during the fabrication or software integration phase allowed a foreign power to remotely overrun controllers at an Iranian nuclear enrichment plant. He warned that if a chip is compromised during manufacture in a foreign foundry, the entire weapon system is compromised. "If the cloud is sitting outside… I am compromised," he stated, referring to the risk of sensitive data flowing through foreign-controlled infrastructure.
The Hypersonic Challenge
As India develops hypersonic missiles—which travel at more than five times the speed of sound—the margin for error disappears. These systems require instantaneous processing of massive data streams to maintain stability and targeting. Dr. Pillai argued that "compensating for weaker hardware with software"—a strategy India currently uses by collating multiple GPS sources to gain accuracy—will not work for hypersonic systems. They require the raw speed of advanced, military-grade hardware that can only be secured if manufactured domestically.
The Critical Mineral Trap
Finally, the panel warned of a looming "resource war." China has effectively monopolized the supply and processing of many rare earth elements and minerals essential for semiconductors. "We don’t even stockpile," Dr. Pillai lamented. He warned that export controls on these materials are coming, and if India does not secure its supply chain now, its future foundries may have the machines but no materials to feed them.
Conclusion
The consensus from the Hindu Semiconductor Summit 2026 is clear: India’s defense future is inextricably linked to its silicon future. While the BrahMos and Sudarshan Chakra represent the muscle and shield of the nation, the semiconductors are the nerves and brain. To remain a sovereign power in an era of AI-driven warfare, India must move faster than the 2035 timeline suggests. The "bus," as Dr. Pillai warned, is leaving the station, and for India’s defense establishment, missing it is not an option.
