India is making bold strides in aerial defense by upgrading its Su-30MKI fighter jets with a cutting-edge radar system — the Virupaksha AESA radar, developed by DRDO. This radar incorporates advanced Gallium Nitride (GaN) technology to deliver better range, target-tracking, and stealth detection capabilities, giving India a significant edge in the increasingly competitive aerial battlefield.
A major leap in India's radar technology
What Makes Virupaksha Radar Special?
Developed by DRDO’s Electronics and Radar Development Establishment (LRDE), the Virupaksha radar is an Active Electronically Scanned Array (AESA) system that uses thousands of small transmit/receive modules (TRMs) to scan, track, and engage targets. These modules allow the radar to operate at higher power with greater speed and accuracy than traditional mechanically scanned radars.
One of the standout features of Virupaksha is its use of Gallium Nitride (GaN) instead of the older Gallium Arsenide (GaAs). GaN allows for higher energy efficiency, longer lifespan, and better heat resistance, enabling the radar to perform well even in the most extreme battlefield environments.

According to defense analysts, Virupaksha can detect a 1-square-meter radar cross-section (RCS) target at more than 250 km and stealth targets (as low as 0.01 sq m RCS) at 200–300 km. This means India can now identify advanced aircraft like China's J-20 or even the U.S. F-35 before they get within missile range — an essential advantage in modern air warfare.
The Backbone of Indian Air Dominance
The Su-30MKI, developed jointly by Russia and India, is a twin-engine, multi-role air superiority fighter. With over 270 units in service, it forms the backbone of the Indian Air Force's frontline defense. These jets are now being upgraded under the 'Super-30' program, which includes advanced avionics, radar systems, and weapons integration to ensure they remain formidable even in 2030 and beyond.
Su-30MKI Before and After Upgrade
Before the upgrade, the Su-30MKI relied on legacy radar systems that lacked the ability to counter stealth threats. With Virupaksha and associated improvements, these jets gain capabilities nearly comparable to fifth-generation fighters. Here’s what the new upgrade package includes:
- Digital cockpit: Modern multi-functional displays to reduce pilot workload
- IRST (Infrared Search & Track): Passive heat-seeking system to detect stealth targets
- Astra MkIII Missiles: Equipped with ramjet propulsion, these can hit targets up to 350 km away
- Improved survivability: Enhanced electronic warfare (EW) suite and countermeasures
Another advanced feature is the radar’s swashplate mechanism, allowing it to tilt and rotate. This grants Su-30MKI pilots a broader radar sweep and near-360-degree situational awareness, making them more effective in both air dominance and support roles.

How India Matches Global Adversaries
With Virupaksha, India is signaling that it won’t fall behind in radar and electronic warfare technologies. Countries like China have been investing heavily in stealth fighters and advanced avionics. To maintain regional air superiority, India must be able to detect, intercept, and neutralize any incoming threat.
Moreover, this radar brings Indian technology closer to the capabilities of the U.S.-made AN/APG-81 radar used in F-35s, though with indigenous advantages and a more cost-effective development cycle. It demonstrates India’s ability to innovate, manufacture, and deploy high-performance systems at scale.
Why This Upgrade Matters
- Counter-stealth capability: Detects modern fighters with minimal radar visibility
- Future-readiness: Prepares India for electronic warfare environments
- Atmanirbhar Bharat: Supports India's vision of defense self-reliance
Looking Ahead
The Su-30MKI was always a powerful fighter, but with the Virupaksha AESA radar and Super-30 upgrades, it enters a new league. It becomes a multirole platform capable of surveillance, electronic warfare, and long-range interception. This transformation ensures that India can maintain its air superiority well into the next decade.
Strategically, this upgrade also shows India's willingness to move away from foreign dependence and toward indigenous systems that are more customizable, easier to service, and strategically secure.
