Aviation researcher Andreas Rupprecht posted footage on LinkedIn that appears to show China’s next-generation high-altitude intelligence, surveillance and reconnaissance drone, an aircraft he estimates is “comparable in size to the US Air Force’s B-21 Raider.”
Rupprecht wrote on LinkedIn that the WZ-X drone was spotted at a secretive air base in China’s Xinjiang region, known to some as China’s version of Area 51:
Two new images of the PLAAF’s latest and largest intercontinental HALE ISR #UAV, provisionally referred to simply as the #WZ-X, have been leaked, apparently showing the aircraft somewhere in Xinjiang. The UAV was first spotted on satellite imagery in May 2025 at the PLAAF’s UAV test centre at Malan Air Base in the Xinjiang Uygur Autonomous Region of northwestern China.
Rupprecht continued:
In recent years, Malan/Uxxaktal (ZWML) has developed into the PLAAF’s main test centre for trialling UAVs and UCAVs of all types, while also serving as the base of the 178th UAV Brigade. Satellite imagery from 2022 onwards shows extensive expansion of the base’s infrastructure, including new hangars, taxiways and facilities likely linked to the previously unknown, very large flying-wing UAVs WZ-X and the similarly mysterious UCAV GJ-X, both of which are roughly comparable in size to the B-21 Raider. As such, the base, much like the second secret air base at Lop Nur, which is likely focused more on manned systems such as the J-36, J-XDS and, eventually, the H-20, is often compared to the US Area 51 because of its remote location and its role in testing next-generation weapon systems.
Based on the few, often blurry, images available, the WZ-X appears to be a twin-engined flying-wing design similar in configuration to the US RQ-180, but considerably larger. Rough estimates suggest a wingspan of about 52 m and a length of roughly 14 m. Its two engines, of unknown type, are reportedly fed by a central top-mounted intake, allegedly covered by a conformal mesh to reduce radar cross-section. Apart from its very wide span, the design appears to feature a relatively spacious central fuselage section and a dorsal SATCOM antenna. Its range is estimated at more than 20,000 km, with a normal cruising altitude of 18-20 km and a cruising speed of Mach 0.5-0.65. As for the manufacturer, some sources claim it was developed by Nantong University (NTU), located in Nantong, Jiangsu province.
The WZ-X could help Beijing locate warships, map air defenses and relay targeting information to China’s massive arsenal of long-range missiles, as well as hypersonic weapons, in the event of a conflict over Taiwan
Last week, a new report from Taiwan’s leading English-language daily newspaper, the Taipei Times, revealed that China had deployed a record 244 coast guard, research and other government vessels around the island.
Technical details about the WZ-X remain scarce, and claims about its capabilities remain unverified. However, the expanding infrastructure at Malan and repeated sightings suggest that the aircraft is undergoing flight testing.
