Chinas Long March 10B Maiden Flight Slated for July 10–13, Will Test Pioneering Sea-Based Net Recovery
Summary: Per a July 5, 2026 CaiLian She report, Chinas Long March 10B maiden flight is slated for July 10–13 at the Wenchang Commercial Spaceport, where it will validate the worlds first sea-based net recovery technology.
Per a July 5, 2026 CaiLian She report, the Long March 10B (CZ-10B) launch window has been set for July 10–13, with the primary liftoff time at around 13:00 Beijing time on July 10. The mission will lift off from the Wenchang Commercial Spaceport in Hainan. The headline objective, beyond placing payloads into orbit, is to validate a sea-based net recovery system for the booster, a procedure that would mark the worlds first such attempt on a launch vehicles first stage.
The CZ-10B is a 5-meter-diameter liquid-fueled rocket, and it is the worlds first 5-meter-class launch vehicle designed to recover its first stage. Instead of the conventional landing-leg configuration, the booster relies on a net structure mounted on a sea-based recovery vessel to catch the descending stage, a mechanism conceptually similar to the arresting-cable recovery used by carrier-based aircraft. Removing the landing legs frees up mass and volume that can be redirected to payload, which proponents argue improves both payload performance and the economics of reusability.
This maiden flight deliberately couples orbital insertion and sea-based booster recovery inside a single launch window, making it the first end-to-end integrated test of the rockets avionics, the downrange tracking network, and the maritime recovery platform working together. Final confirmation of a successful catch and any subsequent assessment of the boosters reusability will come from official channels after the attempt.
