The Xi'an KJ-600 is a Chinese twin-propeller, quad-tail, high-wing military aircraft designed for cargo and airborne early warning and control (AEW&C) intended for carrier-based operations, to be deployed on Type 003 aircraft carriers of the People's Liberation Army Navy from around 2024.
The KJ-600 is a high-straight wing aircraft reportedly powered by a pair of WJ-6 turboprop engine, and sports a quad-fin tailplane, tricycle gear and a large dorsal radome suspected to be fitted with an AESA-type system. A non-flying model was observed on a concrete mockup carrier at Wuhan electronic testing facility, The mockup has a striking external resemblance to the aftward-folding Northrop Grumman E-2 Hawkeye.
The aircraft made its maiden flight on 29 August 2020.[1] Flight testing continued in 2021.[2] [3] A prototype in flight was spotted by aircraft observers above the testing facility in October 2021.[4] In late 2023 "intensive trials" were underway with at least four, possibly even six, prototypes, according to Gu Min Chul.[5]
The Diplomat Rick Joe, who writes extensively on Chinese aviation and naval developments, commented that "fixed wing carrierborne AEW&C are a vital and essential part to any navy that seeks to field a robust and capable carrier airwing, and their ability to enhance a carrier group's offensive and defensive capabilities and overall situational awareness and network-centric warfare is unmatched by any other platform type that will exist in the near future".[6]
Analyst H. I. Sutton believed the KJ-600 will be a massive boost to the PLA Navy, and "[o]nce it enters service on the carriers, it will greatly enhance the aerial and maritime situational awareness [...] [a]nd the offensive and defensive capabilities of the carrier group", and that "Chinese aerospace and military industry has certainly shown its ability to develop quite modern and capable AEW&C systems for other air, naval and ground applications".[7]
