Guizhou WZ-7 Soaring Dragon
The Guizhou WZ-7 Soaring Dragon (Chinese: 无侦-7 翔龙) is a high-altitude long endurance unmanned aerial vehicle (UAV) from the People's Republic of China.[1][3] The design uses a unique joined-wing design.[3]

The primary mission is expected to be aerial reconnaissance, but it may also be fitted to provide targeting data for anti-ship ballistic missiles and cruise missiles.[4]
Development
The WZ-7 was designed by the Chengdu Aircraft Industry Group and constructed by the Guizhou Aircraft Industry Corporation. A model appeared at the 2006 China International Aviation & Aerospace Exhibition.[5] The first flight has not occurred as of 2011. The drone conducted radar cross-section testing.[5] The WZ-7 entered serial production in 2015 to 2016.[2] A complete redesign of WZ-7 was observed in 2020 with the Chinese Air Force roundel. The redesign featured V-tails, a different engine nozzle with the WS-13 turbofan engine, and changes to the ventral fin and the sail structure.[6] The WZ-7 UAV was officially unveiled by the military at the Zhuhai Airshow in 2021.[3][7] It was displayed again in 2022.[8]
Design
Larger than most UAVs, the WZ-7 features a tandem, joined-wing design, which allows for a more rigid, less flexible wing than other configurations, with benefits said to include an increased lift-to-drag ratio and less complex flight controls than a HALE UAV with a conventional wing would require.[9][5][4] The air intake for the engine is mounted atop the fuselage, with the engine itself mounted in the rear of the aircraft.[5] The prototype aircraft is powered by a Guizhou WP-13 turbojet engine, a copy of the Soviet Tumansky R-13; it is anticipated that an improved engine will be installed in production aircraft.[5][10]
The operational WZ-7 has a significantly modified shape. The single vertical tail on the prototype was changed to a pair of canted tails.[11] A turbofan engine was installed on the production model.[6] Due to the different engine and aerodynamics, the endurance of the production model is unknown. It is speculated to be longer than the 10 hours advertised for the prototype.[11]
Operational history
The WZ-7 entered service with the People's Liberation Army Air Force in 2018[1] and were spotted deployed to the Tibet Autonomous Region, Hainan Island and Yishuntun Airbase near North Korea.[12]
On 24 July 2019, a WZ-7 shadowed the American Ticonderoga-class cruiser USS Antietam which was transiting the Taiwan Strait.[13]
On 1 January 2023, a WZ-7 flew through the Miyako Strait into the Philippine Sea and returned to the East China Sea through the same route.[14][15]
