The Shaanxi KJ-500 (Chinese: 空警-500; pinyin: Kōngjǐng Wǔbǎi; literally: "Air Warning 500"), also known as Qianliyan-500[2] (Chinese: 千里眼-500; pinyin: qiān lǐ yǎn-500; lit. 'All-seeing-500') is a third-generation airborne early warning and control (AEW&C) aircraft used by the Chinese People's Liberation Army Air Force (PLAAF). It was built by Shaanxi Aircraft Corporation,[3] and is based on the Y-9 airframe.

Development

Since the beginning of the 21st century, the detection range and the accuracy of airborne radars have been increasing, and fighters equipped with various types of air-to-air missiles and low-altitude cruise missiles continue to improve in performance, creating a demand for a more capable AEW&C. To address the above issues, China began developing the KJ-500, China's third AEW&C model, in the late 2000s. The KJ-500 was required to have three important features, including good detection capability, good identification, and quick responsiveness. The KJ-500 was also required to be the core force of the information combat system; its equipment was required to have characteristics of networking, multi-functionality, high-integration, and lightweight.[4]

The aircraft carries a fixed dorsal radome containing three AESA radar arrays for 360-degree coverage and is said to be more efficient than the two-planar 'balance beam' array design used on the earlier KJ-200. Production of older AEW&C types reportedly ceased in 2018 in response to the KJ-500 reaching full operational capability.[5]

KJ-500A's radome and aerial refueling probe

In April 2018, China began testing KJ-500A,[6] an improved variant with aerial refueling capability and other sensor enhancements.[7] By August 2018, at least two units were built. The KJ-500A reportedly entered service in late 2020. As of 2023, the KJ-500A had become the production standard with 7-8 airframes built.[6]

Operational history

[edit]

In March 2022, General Kenneth Wilsbach, commander of U.S. Pacific Air Forces, identified the KJ-500 as an enabler for long-range Chinese air-to-air missiles.[8]

Export and potential sales

[edit]

On 6 June 2025, Pakistan's government officially announced the country's plan to acquire the KJ-500.[9][10][11]
