What Is the KJ-3000 AWACS and Is China Mass Producing It?

Four of China’s new KJ-3000 airborne early warning and control aircraft have been photographed together at the Xi’an Aircraft Company facility at Xi’an-Yanliang, in the clearest sign yet that the country’s heaviest radar jet is moving from flight testing into series production. Commercial satellite imagery captured by Vantor on October 5, and published by the American defence outlet The War Zone on October 22, shows three of the aircraft near the factory in the western part of the airfield and a fourth at the neighbouring China Flight Test Establishment. J. Michael Dahm, a senior fellow at the Mitchell Institute for Aerospace Studies, assessed that four airframes on one site point to serial production having begun. A fleet of KJ-3000s would give China a heavy airborne command post built on a domestic airframe and domestic engines, something its air force has lacked since it first fielded jet-powered radar aircraft two decades ago.

The assessment is far from unanimous, with Andreas Rupprecht, a widely cited analyst of Chinese military aviation, noting that the imagery is consistent with low-rate initial production but could equally show all four previously identified prototypes at the facility at the same time, and identifying the aircraft at the flight test centre as one of those prototypes. The program first became visible in December 2024, when low-quality photographs of a Y-20 transport carrying a large circular radome circulated online, followed in May 2025 by clearer images of an aircraft in primer bearing the serial number 7821. The KJ-3000 is built on the improved Y-20B, powered by WS-20 turbofans, and carries an aerial refuelling probe above the cockpit. The Pentagon’s 2025 annual report on Chinese military power stated that the type “will probably be the world’s first model to use digital radar and will be capable of anti-jamming, passive detection, and target identification.”

The significance of serial production lies in the limits of China’s earlier heavy fleet, with only four KJ-2000 aircraft having been completed because the program depended on Russian-built Il-76MD airframes that were never available in numbers. The smaller Y-9 based KJ-500, by contrast, has been produced at a considerable pace and has become central to People’s Liberation Army Air Force operations, with then-Pacific Air Forces commander General Kenneth Wilsbach stating in 2022 that Chinese long-range air-to-air missiles benefited from KJ-500 support for J-20 fighter operations. A jet-powered successor flying higher and further offshore would extend that coverage across the waters around Taiwan and Yonaguni and towards the routes used by China’s growing carrier force, particularly as the U.S. Air Force’s own effort to replace the E-3 Sentry has faced repeated setbacks, with the Pentagon having proposed cancelling the E-7 Wedgetail in 2025 after its unit cost rose from $588 million to $724 million before Congress restored funding.

The configuration of the KJ-3000’s radar has not been disclosed, although the KJ-2000 and KJ-500 both use fixed radomes housing three active electronically scanned arrays for 360-degree coverage rather than the rotating antennas of the E-3 and the Russian A-50. Detection ranges of 600 to 1,000 kilometres against conventional aircraft have been circulated by some analysts, but these remain unverified estimates with no confirmed figure for stealth targets. The October 5 imagery shows no sign that any of the aircraft has been delivered to an operational unit, and satellite pictures alone cannot establish how many of the four carry complete mission systems.
