The development of Shenlong is closely tied to China’s broader aspirations to become a global space power. The project is overseen by the China National Space Administration (CNSA) in coordination with the People’s Liberation Army (PLA), highlighting its dual-use nature—both for military and civilian applications.
Shenlong was first publicly acknowledged in 2007 when images of a scale model attached to an H-6 bomber (a Chinese version of the Soviet-designed Tupolev Tu-16) were released. This image confirmed suspicions that China was actively working on a spaceplane project. The first flight of the Shenlong space plane reportedly occurred in 2011, although little information was disclosed at the time. Since then, subsequent test flights have been conducted under significant secrecy, further fueling speculation about its technical capabilities and purpose.
Influences from Other Spaceplane Programs
Shenlong shares similarities with other spaceplane designs, particularly the United States’ X-37B Orbital Test Vehicle, operated by the U.S. Air Force. Both Shenlong and the X-37B are unmanned, reusable spaceplanes designed for long-duration orbital missions, suggesting that China may have drawn inspiration from earlier U.S. and Soviet spaceplane projects. However, Shenlong’s specific characteristics remain largely unverified due to the limited information released by the Chinese government.
Technical Specifications
While precise technical details of the Shenlong space plane remain classified, analysts have deduced certain features based on available imagery and reports. Shenlong is believed to be a small, unmanned spaceplane designed for low Earth orbit (LEO) missions. Its reusable nature allows it to carry out multiple missions, reducing overall costs and increasing operational flexibility.
Design and Structure
Shenlong appears to have a compact, winged design, similar in size to the U.S. X-37B. Its aerodynamic structure suggests it is optimized for both atmospheric flight and space operations, allowing it to glide back to Earth after completing its missions in space. The spacecraft likely uses a heat-resistant coating or thermal tiles to withstand the intense temperatures encountered during re-entry into Earth’s atmosphere.
Launch and Recovery
Shenlong is expected to be launched aboard a conventional rocket, likely the Long March series, which is China’s mainstay for satellite and spacecraft launches. The spaceplane would be carried to orbit atop the rocket, after which it could deploy payloads, conduct experiments, or carry out other tasks. Once its mission is complete, Shenlong would re-enter the atmosphere and glide back to a designated landing site, similar to NASA’s retired Space Shuttle program or the U.S. X-37B.
Payload Capacity
Although Shenlong’s exact payload capacity remains unknown, its small size suggests it can carry limited payloads, likely in the range of a few hundred kilograms. This capacity would be sufficient for deploying small satellites, conducting scientific experiments, or testing space technologies in orbit. There is also speculation that Shenlong could be equipped with reconnaissance or intelligence-gathering instruments, making it a valuable asset for military surveillance and space-based observation.
Potential Applications of Shenlong
The Shenlong spaceplane has a wide range of potential applications, spanning both civilian and military domains. While China has not fully disclosed its intended uses for Shenlong, the following sections explore the most likely scenarios for its operational deployment.
Scientific and Technological Research
One of the most significant civilian applications for Shenlong is its potential for scientific research in space. Spaceplanes like Shenlong provide a platform for testing new materials, technologies, and experiments in a microgravity environment. Shenlong could also contribute to space research by carrying out long-duration missions in low Earth orbit and deploying scientific instruments or small satellites. The ability to recover these payloads after re-entry would offer valuable data for ongoing research and development.
Military Uses
The potential military applications of Shenlong have drawn significant attention from analysts. As an unmanned, reusable spaceplane, Shenlong could be used for various defense-related missions, including satellite deployment, reconnaissance, and intelligence-gathering.

Additionally, Shenlong could serve as a testbed for anti-satellite (ASAT) weapons or other military technologies. The U.S. and other nations have expressed concern that Shenlong, like other spaceplanes, could be used for “dual-use” purposes, meaning it has the potential to carry out both civilian and military missions. The classified nature of China’s spaceplane program only heightens these concerns.
Commercial and Economic Implications
Shenlong also holds promise in the commercial space sector. As reusable spaceplanes become more prevalent, they offer the potential for reducing the costs associated with launching payloads into orbit. While Shenlong is primarily a military and government program at this stage, its technology could eventually be adapted for commercial applications, such as satellite deployment or space tourism. Furthermore, the development of Shenlong indicates China’s growing interest in developing its private space sector, mirroring the trajectory of commercial space ventures in the United States and Europe.
Strategic Significance of Shenlong
China’s development of the Shenlong spaceplane underscores its long-term ambitions in space. By developing reusable spacecraft, China is signaling its commitment to becoming a leading space power, alongside the United States and Russia.
