China’s Long March 12B takes off as reusability tests wait

China has declared the Long March 12B’s first flight a “complete success,” even though the launch made no attempt to land the booster stage. The rocket flew with grid fins and landing legs for future recovery work, while carrying Qianfan broadband satellites i

For Monday’s launch, the real suspense wasn’t about what came down—it was about what was built to come down later.

China’s Long March 12B lifted off carrying grid fins and landing legs, hardware meant for first-stage recovery experiments. No attempt was made during the flight to bring the booster back. In a post-launch statement. the China Aerospace Science and Technology Corporation (CASC). the parent company of CACL. said the first flight of the Long March 12B was a “complete success.”.

“This launch adds another high-capacity commercial rocket to [China’s] fleet for large-scale Internet constellation networking missions,” CASC said. It added: “No recovery tests were conducted during this mission; however. first-stage recovery tests are scheduled to be carried out at a later. opportune time.”.

The payload matched the direction of travel. Satellites for one of China’s large-scale Internet constellations rode to space on the Long March 12B. The rocket released a batch of Qianfan broadband spacecraft into low-Earth orbit. Qianfan is described as one of China’s two leading mega-constellations. both aiming to replicate for China what SpaceX’s Starlink does in the United States.

The tension between ambition and restraint shows up in the recovery hardware itself. The rocket carried components associated with landing and guidance—grid fins and landing legs—but the first stage remained on its own path upward. CASC’s wording leaves the next chapter open-ended. promising tests “at a later. opportune time. ” rather than confirming a specific date.

Behind the headline, China’s broader launch history stretches back decades. The Long March rocket family dates to 1970. when China launched its first satellite into orbit using the Long March 1 vehicle. derived from Chinese ballistic missiles. The series evolved through the Long March 2, 3, and 4 rockets, which served as workhorses in the 1980s, 1990s, and 2000s. Many of those older systems remain operational. but they are being replaced by newer models such as the Long March 5. 6. 7. and 8. built to launch everything from small satellites to massive modules for China’s space station.

What’s newly complicated is that the Long March 12 family now includes three different designs. The original Long March 12 debuted in 2024. It uses four kerosene-fueled main engines and initially flew with a conventional, expendable design. The Long March 12A, by contrast, was launched in December and is described as partially reusable. That version replaced the Long March 12’s kerosene-fueled engines with a methane-fueled propulsion system outsourced to a private engine builder.

The Shanghai Academy of Spaceflight Technology (SAST) managed the development of both the Long March 12 and 12A.

All of that history matters because it frames Monday’s flight as more than another payload delivery. It was another step in building a reusable-capable capability—grid fins and landing legs installed. landing tests withheld for a later moment—while simultaneously pushing forward with the Qianfan constellation push into low-Earth orbit.
