DRDO Unveils Indigenous Chips for Advanced Radars and Missiles
DRDO unveils advanced indigenous semiconductor chips for radars, electronic warfare, and tactical missiles at ESTIC 2026 in New Delhi.
In a significant leap toward self-reliance in critical defence technology, the Defence Research and Development Organisation (DRDO) has showcased its latest DRDO indigenous semiconductor chips designed for high-stakes applications. These cutting-edge components are set to power advanced radar systems, electronic warfare suites, and tactical missiles, reducing dependence on foreign imports for strategic security.
The unveiling took place during the Emerging Science, Technology and Innovation Conclave (ESTIC) 2026, held at Bharat Mandapam in New Delhi from October 27 to 29. The event, themed 'Creative Minds, Catalysing Science, Empowering Society', was inaugurated by Prime Minister Narendra Modi and jointly organised by 12 different ministries and departments.
The 'Eyes' of the Missile: IRFPAs and MMICs
A primary highlight of the showcase was the work of the Solid State Physics Laboratory (SSPL) in Delhi. The DRDO displayed Monolithic Microwave Integrated Circuits (MMICs) and Infrared Focal Plane Arrays (IRFPAs), both of which are vital for modern warfare.
Advanced Radar and Electronic Warfare
The Ministry of Defence revealed that Multi-Chip Modules (MCMs) and MMICs based on Gallium Nitride (GaN) and Gallium Arsenide (GaAs) have already been integrated into several strategic missions. These components act as the fundamental building blocks for Electronic Warfare (EW) applications and sophisticated radar systems, allowing for better detection and signal processing.
Precision Targeting for Missiles
The showcased IRFPAs serve as the "eyes" of tactical missiles. By utilizing Imaging Infrared (IIR) seekers, these systems enable missiles to detect and track targets with extreme precision during the terminal phase of flight. The DRDO demonstrated its versatility by covering three distinct infrared spectrums:
- Short-Wave Infrared (SWIR)
- Mid-Wave Infrared (MWIR)
- Long-Wave Infrared (LWIR)
Beyond Chips: A Suite of Future Technologies
While semiconductors took center stage, the DRDO also displayed a wide array of other futuristic technologies that signal India's growing scientific ambition. These included:
- Scramjet engine technology for hypersonic capabilities.
- Neuromorphic accelerators and advanced communication systems.
- Quantum Random Number Generators (QRNGs) for secure encryption.
- Photonic Integrated Circuits (PICs) and laser proximity sensors.
Driving the Semiconductor Ecosystem
As one of the key organisers of ESTIC 2026, the DRDO led a specialized thematic session titled 'Semiconductors and Next-Generation Chips', chaired by Dr BK Das, Distinguished Scientist and Director General of Electronics and Communication Systems.
During a panel discussion, experts delved into the evolving landscape of microprocessors, purpose-built Artificial Intelligence (AI) System-on-Chips (SoCs), and the concept of "intelligence at the silicon edge." The DRDO also emphasized its commitment to fostering an ecosystem where domestic industries and start-ups can collaborate to design next-generation chips.
The Strategic Importance of Silicon Sovereignty
The Ministry of Defence underscored that semiconductor technology is not just a technical achievement but a pillar of national security, digital security, and economic strength. To ensure a robust supply chain, India is focusing on the entire lifecycle of the chip—from design and fabrication to testing and industrial-scale production.
India's expertise is being cultivated across several specialized facilities, including:
- Solid State Physics Laboratory (SSPL)
- Gallium Arsenide Enabling Technology Centre (GAETEC)
- Semiconductor Technology and Applied Research Centre (STARC)
- Semiconductor Laboratory (SCL)
These institutions have developed deep expertise in mature silicon process technologies, Micro-Electro-Mechanical Systems (MEMS), and the use of GaN and GaAs, positioning India as a growing player in the global semiconductor arena.
