China successfully launched the fourth flight of its classified Shenlong reusable spaceplane on February 7, 2026, aboard a Long March 2F rocket from Jiuquan Satellite Launch Center. The mission, designated CSSHQ-4, continued the technology demonstration program for China's X-37B analogue spacecraft. This flight focused on validating advanced propulsion systems and in-orbit servicing capabilities, representing incremental progress in China's development of autonomous reusable space vehicles.

The Long March 2F, a human-rated medium-lift launch vehicle operated by China Aerospace Science and Technology Corporation, provided reliable access to orbit. The rocket lifted off from the Jiuquan launch facility in northwest China, which has served as the primary launch site for Chinese crewed missions and major national projects. The vehicle's proven track record made it an ideal choice for this sensitive national program.

The mission concluded successfully, with the Shenlong spaceplane completing its orbital operations and returning for autonomous runway landing. This fourth flight demonstrated China's advancing capabilities in reusable spacecraft technology and on-orbit servicing, key technologies for future deep space exploration and space infrastructure maintenance. The program represents a significant milestone in China's effort to develop fully reusable space transportation systems comparable to international counterparts.
