China’s new airborne early warning and control aircraft, the KJ-3000, is drawing attention from military planners across the world.Based on the indigenous Y-20B strategic transport aircraft, the KJ-3000 is expected to become one of the most advanced airborne surveillance platforms in China’s inventory. The Y-20B is among the largest transport aircraft currently in production and gives Beijing a large airframe on which to build a long-range airborne warning system.According to the Pentagon, the KJ-3000 is likely to be the world’s first airborne early warning aircraft built around a digital radar architecture. It is expected to feature advanced anti-jamming, passive detection and target-identification capabilities.Airborne early warning aircraft are often described as force multipliers because they extend radar coverage beyond ground-based systems, improve situational awareness and help coordinate fighter operations across large areas.The KJ-3000 is currently undergoing flight testing, with two known prototypes seen so far. It is powered by China’s latest WS-20 turbofan engines. The aircraft uses four WS-20 engines, each generating around 138 kN of thrust, with better fuel efficiency than the Russian D-30 engines used on earlier Y-20 platforms.This is important because greater engine efficiency can increase endurance and help meet the substantial power demands of next-generation airborne early warning systems.China has not released technical specifications of the KJ-3000’s radar system. However, images of the aircraft show a large radar mounted on a dorsal radome, which appears significantly larger than the radar on the KJ-500.Traditional AWACS radars process much of their signal through dedicated hardware. A digital radar architecture shifts more of that processing into software-driven systems. This allows faster signal processing, better resistance to electronic warfare and easier upgrades over time.Combined with passive detection capabilities, such a system could allow the aircraft to identify or track targets while reducing its own electronic signature.Over the past two decades, China has steadily expanded its inventory of AEW&C aircraft, moving from a small number of high-value platforms to a large and layered force capable of supporting operations across multiple theatres.China’s airborne warning fleet is currently centred around the KJ-500, which has become the backbone of the People’s Liberation Army’s airborne surveillance network.According to the International Institute for Strategic Studies’ Military Balance 2025, the PLA Air Force operates around 40 KJ-500 aircraft, while the PLA Navy operates more than 20, giving China a fleet of over 60 aircraft in this category alone.China also operates a small number of KJ-2000 heavy AWACS aircraft based on the Russian Il-76 airframe. These platforms were the first to give China long-range airborne warning capability.Beijing is also developing the carrier-based KJ-600 for its expanding aircraft carrier fleet.The AWACS balanceThe United States remains the benchmark in airborne warning operations, but its own fleet is undergoing a transition.The US Air Force’s primary AWACS platform remains the E-3 Sentry, a system that entered service during the Cold War. After years of retirements and maintenance challenges, the E-3 fleet has declined steadily, with only around 14 aircraft remaining in operational service. The US Navy complements these aircraft with the carrier-based E-2D Advanced Hawkeye.Although the United States retains unmatched experience in airborne battle management, China is rapidly narrowing the gap in this domain.India’s airborne early warning and control capability remains significantly smaller than China’s.The Indian Air Force currently operates three Israeli-origin Phalcon AWACS mounted on Il-76 aircraft and three indigenous Netra AEW&C aircraft based on the Embraer ERJ-145 platform.While these systems have provided valuable surveillance and command-and-control capability, their limited numbers constrain the IAF’s ability to maintain continuous airborne coverage across multiple fronts.India has initiated efforts to expand its airborne surveillance fleet. The DRDO is developing the Netra Mk-1A, while the larger AWACS India programme aims to integrate advanced indigenous mission systems onto Airbus A321 aircraft.Beijing, meanwhile, is building a layered airborne surveillance network capable of supporting sustained operations across multiple theatres. This numerical advantage allows China to maintain continuous coverage over key regions such as Tibet, the Taiwan Strait, the East China Sea and the South China Sea, while retaining operational flexibility.The emergence of the KJ-3000 is therefore a reminder that future airpower competition will not depend only on fighters and missiles. It will also depend on the ability to collect, process and distribute information across the battlefield.
