Satellite images show four KJ-3000 radar jets at China's Xian aircraft plant

Commercial satellite imagery taken on 5 October shows four of China's new KJ-3000 airborne early warning and control aircraft at the Xian Aircraft Company complex at Xian-Yanliang, TWZ reported on 22 October. Three of the large radar jets were parked near the factory on the western side of the site, while a fourth stood at the neighbouring China Flight Test Establishment, according to the images supplied by the satellite firm Vantor.

Analysts disagree on what the sighting means. J. Michael Dahm, a senior fellow at the Mitchell Institute for Aerospace Studies, judged that four airframes in one place indicate the type has entered serial production, TWZ reported. Andreas Rupprecht, who tracks Chinese military aviation, was more cautious: he said the imagery could point to series or low-rate initial production, but also that all four known prototypes might simply have been at the plant together. He identified the aircraft at the flight test area as a prototype. TWZ noted that the imagery alone does not confirm that serial production has started.

The KJ-3000, also called the KJ-20 in some reporting, is built on the Y-20B, an improved version of the Y-20 heavy transport fitted with Chinese-made WS-20 engines. It carries a large circular radome above the rear fuselage, a row of antennas on the forward fuselage, an air-to-air refuelling probe above the cockpit and a cooling intake at the base of the tail. The first photographs of the aircraft in flight began circulating in late December 2024, and reports at the time said its maiden flight had taken place on 29 November 2024.

The new jet is expected to replace the People's Liberation Army Air Force fleet of KJ-2000 radar aircraft. Only four KJ-2000s were built, all on Russian-made Il-76 airframes, which left the programme short of suitable aircraft and dependent on Russian supply chains. A home-built Y-20 airframe gives China a basis for a much larger fleet. Asian Military Review reported in December 2025 that the KJ-3000 was then still in flight trials and that the four KJ-2000s are all based in Jiangsu province.

According to TWZ, the US Department of Defense said in its 2025 annual report on Chinese military power that the PLA had carried out an initial flight of the KJ-3000. The report described it as a surveillance aircraft for tracking aircraft, ships and other vehicles, and said it would probably be the first such model to use a digital radar, with anti-jamming, passive detection and target identification features. The same report said support aircraft such as the KJ-500 had improved PLA surveillance during surge operations near Taiwan.

A jet-powered radar plane flies faster, higher and longer than the turboprop KJ-500 and the newer KJ-700, which are based on the Y-9 transport and regularly appear over the Taiwan Strait and at Chinese island outposts, TWZ reported. A higher-flying radar can better spot low-flying aircraft and missiles, and the type could act as a networking hub that passes targeting data to fighters such as the J-20. Asian Military Review, citing the Military Balance, put the KJ-500 fleet at about 40 aircraft in the air force and more than 20 in the navy.

For Taiwan, a growing fleet of long-endurance radar aircraft would widen the PLA's picture of air and sea traffic around the island and over its maritime approaches. Further imagery of more airframes, or of aircraft in operational unit markings, would be needed to show how fast the KJ-3000 is entering service.
