The Indian Air Force (IAF) is set to significantly enhance the combat prowess of its Su-30MKI fleet through the ambitious Super-30 Program, with upgrades slated to commence in 2026. This transformative initiative will equip 84 Su-30MKI aircraft with the cutting-edge Virupaksha Gallium Nitride (GaN)-based Active Electronically Scanned Array (AESA) radar and a fully automated digital cockpit, marking a major leap in India’s air superiority capabilities. The program, driven by indigenous innovation, underscores India’s commitment to self-reliance in defense technology under the Atmanirbhar Bharat initiative.
At the heart of the Super-30 Program is the Virupaksha AESA radar, developed by the Electronics and Radar Development Establishment (LRDE) under the Defence Research and Development Organisation (DRDO). This state-of-the-art radar, featuring approximately 2,600 Transmit/Receive Modules (TRMs), leverages GaN technology to deliver unparalleled performance.
Compared to legacy systems like the N011M Bars radar currently equipping the Su-30MKI, the Virupaksha offers:
- Superior Range: Capable of detecting fighter-sized targets at distances of 300-400 km, enabling early engagement and enhanced situational awareness.
- Reduced Weight: Weighing significantly less—potentially 30-40% lighter than its predecessor—the radar improves aircraft agility and fuel efficiency.
- Optimized Power Consumption: GaN technology ensures lower energy demands, aligning with the Su-30MKI’s existing AL-31F engines without requiring costly upgrades.
- Enhanced Cooling Efficiency: Advanced thermal management extends the radar’s lifespan and reliability in high-stress combat environments.
- Higher Resolution: Improved target identification and multi-target tracking capabilities, critical for modern warfare scenarios involving stealth and electronic countermeasures.
The Virupaksha radar’s ability to function as a “mini-AWACS” enhances the Su-30MKI’s role in deep surveillance and networked operations, making it a formidable asset against evolving regional threats, including stealth aircraft like China’s J-20 or potential adversaries’ fifth-generation platforms.
Complementing the radar upgrade, the Super-30 Program includes a fully automated digital cockpit designed to revolutionize pilot interaction and mission efficiency. Replacing analog displays with advanced multi-function displays (MFDs), a wide-area head-up display (HUD), and voice-activated controls, the new cockpit will reduce pilot workload and enhance decision-making. Integrated with indigenous avionics, including mission computers and software-defined radios, the cockpit will enable seamless connectivity with other IAF assets, supporting network-centric warfare. This upgrade elevates the Su-30MKI to a 4.5+ generation platform, ensuring its relevance well into the 2040s.
The production of the Virupaksha AESA radar is a collaborative effort involving India’s private and public sectors, with four leading companies shortlisted by LRDE as Development Cum Production Partners (DcPP):
- Astra Microwave Products Limited: A key player in radar and electronic warfare systems, known for its expertise in microwave components.
- Hindustan Aeronautics Limited (HAL): The lead integrator for the Su-30MKI upgrades, HAL brings decades of experience in aircraft manufacturing and avionics integration.
- ICOMM Tele Limited: A rising name in defense electronics, specializing in communication and radar systems.
- Larsen & Toubro Limited (L&T): A conglomerate with proven capabilities in defense engineering and high-precision manufacturing.
These vendors, selected through a rigorous technical evaluation, will compete for contracts based on cost-effectiveness, with the lowest bidder securing mass production rights. The first radar from the chosen private sector partner is expected to commence trials in 2026, marking the start of the Super-30 Program’s implementation phase. This public-private partnership not only accelerates production but also strengthens India’s defense-industrial ecosystem, creating jobs and fostering innovation.
The Super-30 Program, with an estimated cost of ?65,000 crore (approximately $7.8 billion), is a critical component of the IAF’s modernization strategy. The Su-30MKI, forming the backbone of the IAF with over 260 aircraft, will remain a mainstay until at least 2045. Upgrading 84 jets in the first phase ensures that the fleet remains competitive against regional adversaries, particularly in light of China’s growing fifth-generation fighter inventory and Pakistan’s potential acquisition of advanced platforms.
The program’s timeline is ambitious yet achievable. With the Virupaksha radar’s design phase already complete and subsystem realization underway, prototype testing is expected to begin soon after 2025. Ground trials will precede in-flight testing on Su-30MKI testbeds, with full-scale integration starting in 2026. The upgrades, including the digital cockpit, will be rolled out progressively, with HAL overseeing the retrofit process at its Nashik facility.
