BEIJING, July 10, 2026 — Two years after its maiden flight, China’s Long March 10B rocket is beginning to reshape the economics of the country’s space launch industry, with officials at the China Aerospace Science and Technology Corporation (CASC) now reporting a measurable reduction in per-mission costs.
The rocket, which completed its first successful booster recovery on June 23, 2024, from the Wenchang Space Launch Site in Hainan province, has since flown multiple missions, and data from CASC shows the reusable first-stage design is delivering on its promise to cut expenses. The 2024 flight was a landmark.
At 8:00 a.m. local time, the Long March 10B lifted off carrying a test payload, and its first stage later executed a controlled descent, landing on a ship-borne platform, the Bo Run Jiu Zhou, stationed in the South China Sea. That recovery made China the second nation, after the United States, to successfully recover an orbital-class rocket booster. The rocket is powered by the new YF-100K engine, a kerosene-liquid oxygen design producing 120 tons of thrust at sea level.
CASC officials said the development program, which began in 2019, involved an investment of approximately 5 billion yuan, or about $690 million at the time. The maiden flight had originally been scheduled for 2023 but was delayed by technical challenges in the landing system.
Those hurdles have since been resolved, and the rocket is now in regular service. The Long March 10B is a medium-lift vehicle with a capacity of roughly 14 metric tons to low Earth orbit and 6 metric tons to geostationary transfer orbit. Its reusable first stage, capable of vertical landing, is similar in concept to SpaceX’s Falcon 9.
CASC officials noted that the recovery capability is expected to reduce launch costs by up to 30% for future missions. With several launches now completed, company data indicates those savings are being realized, though CASC has not released a precise per-kilogram cost figure.
Commercial and strategic implications
For Central Asian nations looking to expand their satellite infrastructure, the cost reduction is a significant development. Kazakhstan, for example, operates the KazSat series of communications satellites and has relied on a mix of domestic and foreign launch providers. A 30% reduction in launch costs from a proven Chinese vehicle could make CASC a more competitive option for regional governments and commercial operators, particularly for payloads in the 6- to 14-metric-ton range.
The rocket is expected to support China’s space station resupply missions and commercial satellite launches. That dual-use profile — serving both state and private customers — mirrors the approach taken by Western launch providers and gives CASC a stronger foothold in the global launch market.
Company officials have not disclosed the number of commercial contracts signed to date, but the vehicle’s flight record suggests growing demand. China’s broader space ambitions include a reusable heavy-lift rocket, the Long March 9, and a crewed lunar mission planned by 2030. The Long March 10B serves as a proving ground for the technologies that will underpin those larger programs.
Chief designer Zhang Wei of CASC oversaw the 2024 mission. For now, the Long March 10B represents China’s most tangible step toward reusable launch capability.
The question for the global market is whether CASC can scale the technology and match the cost discipline of established competitors. Data from the company’s first two years of operations suggests progress, but the full financial impact will only become clear as the rocket’s flight rate increases.
