China’s Area 51 Expands: Giant Hangars to Accommodate Fleets of Next-Generation Aircraft
The expansion of a highly secretive Chinese airbase in the country’s northwest is accelerating. Described as China’s “Area 51” because of its growing role in testing experimental aircraft and advanced aviation platforms, the facility is involved in the development of next-generation fighter jets and other projects of a military nature.
The latest satellite imagery, captured by Planet Labs on August 27, 2026, reveals the scale of the transformation taking place at the base, which is located near the renowned Lop Nor nuclear testing site in the remote Xinjiang region.
According to Time War Zone, the facility has one of the longest runways in the world, measuring 16,400 feet, or approximately 5,000 meters. Within just a few years, it has evolved from a limited-capability airstrip into a major flight-test center operated by China’s People’s Liberation Army.
The site has historically been associated with military space-development programs and reusable spaceplane projects. Its importance has grown further as China has shifted toward testing a new generation of advanced combat aircraft.
Last year, prototypes of China’s two sixth-generation fighters, the J-36 and J-XDS, appeared at the base for the first time, away from their primary airbases.
Giant Hangars and New Taxiways
Major development work at the base began in 2023, with the expansion of aircraft parking areas and the addition of new hangars. Construction activity then accelerated noticeably from May 2025 onward.
Recent imagery shows an expanded network of aircraft taxiways, turning aprons and support facilities, allowing aircraft movements and testing operations to be increased without disrupting use of the main runway.
Particular attention is focused on three enormous hangars currently under construction in the southern section of the base. Each measures approximately 80 meters long and 40 meters wide, in addition to a fourth separate hangar. These structures are directly connected to a new taxiway and appear to be designed to accommodate larger and more sophisticated aircraft than conventional fighter jets.
The dimensions of the hangars are sufficient to accommodate a range of tactical and strategic aircraft operated by the Chinese air force. However, their exceptional size suggests that Beijing may be preparing to host aviation programs that have not yet entered service or remain in the early stages of testing.
Is the Base Preparing to Host the H-20 Stealth Bomber?
The latest expansion has sparked speculation that the base could become a testing site for China’s anticipated H-20 stealth bomber, which has not yet been publicly unveiled. The base’s isolated location, the sensitive nature of the programs associated with it, and the extensive hangars currently under construction have all made it a potential candidate for hosting part of the testing program for the new strategic bomber, although this remains speculative.
The development work is not limited to hangars and runways. Additional facilities are also being constructed and could include fuel-storage infrastructure, new buildings, worker accommodation areas and a concrete-mixing plant, indicating that the expansion is still far from complete.
A new taxiway is also being built to connect the parking areas with the northern section of the runway. In addition, a huge circular apron is under construction and is believed to be intended for engine testing and aircraft maneuvering. It could also provide an area that would allow sensitive experimental platforms to be concealed from satellite surveillance.
