The Shaanxi KQ-200 () is a Chinese anti-submarine (ASW) and maritime patrol aircraft (MPA) manufactured by Shaanxi Aircraft Corporation. It is based on the Shaanxi Y-8 or Y-9 and has been called the Y-8Q and Y-9Q. Enthusiasts called it GX-6 ().
The aircraft was in People's Liberation Army Naval Air Force (PLANAF) service by 2017.
The KQ-200 has a chin-mounted surface search radar, a magnetic anomaly detector in a tail boom, and an electro-optical camera in a belly turret. Lightweight torpedoes are carried in internal bays. Sonobuoys are deployed from four internal rotary cabinets.
Two prototypes were built by late-2011. A new production line for the aircraft may have opened in late-2016.
The PLANAF received its first KQ-200 in 2015. By 2017, they were deployed by the Southern Theater Command and all three theater commands by 2023.
One may have crashed in the Gulf of Tonkin in March 2022.
