WENCHANG, July 10 — China’s space program achieved a milestone last month that officials in Beijing are now framing as a strategic breakthrough, though Western analysts caution against overstating its immediate military implications. On June 23, 2024, the Long March 10B rocket lifted off from the Wenchang Space Launch Site on Hainan Island, completing its maiden flight with a successful booster recovery. The event marks China’s first recovery of a liquid-fueled rocket stage, a technology that only two other entities—SpaceX and Blue Origin—have demonstrated operationally.
The rocket, developed by the state-owned China Aerospace Science and Technology Corporation (CASC), is a two-stage, medium-lift vehicle designed from the outset for reusability. According to state and international reports, the first stage performed a controlled descent and landed at a designated recovery site.
The flight carried a test payload intended for satellite deployment verification, though Chinese officials have not disclosed the payload’s specific mission or orbit. For observers in Tehran and across the Middle East, the development carries a familiar weight. Iran has long watched China’s space ambitions with a mix of envy and calculation—Tehran’s own satellite launch attempts have been erratic, often drawing international criticism over dual-use technologies that could advance ballistic missile capabilities.
China’s steady, methodical progress stands in contrast.
Technical specifications and cost calculus
CASC has stated that the Long March 10B can deliver approximately 14 metric tons to low Earth orbit (LEO) and 6 metric tons to geostationary transfer orbit (GTO). Those figures place it in the same payload class as SpaceX’s Falcon 9, though direct comparison is complicated by differences in design philosophy and operational history. The Chinese rocket’s reusability is projected to reduce launch costs by up to 30% per mission, according to CASC’s own estimates—a figure that remains theoretical until a track record of multiple re-flights is established.
The cost reduction claim is significant for China’s commercial satellite ambitions. CASC has indicated it plans to use the Long March 10B for future commercial satellite launches and potential crewed missions to China’s Tiangong space station.
The Tiangong station, now permanently occupied, represents China’s long-term bet on sustained human presence in orbit—a bet that requires affordable, reliable resupply.
Regional and global context
China’s space program, under the China National Space Administration (CNSA), has conducted over 500 orbital launches since 1970. In 2023 alone, the country executed 67 launches, a pace that rivals the United States and far exceeds Russia’s current cadence. The Long March 10B’s success adds a reusable option to that fleet, potentially accelerating launch tempo while lowering per-mission expense.
The achievement positions China alongside SpaceX and Blue Origin in the small club of entities that have recovered a liquid-fueled booster. SpaceX’s Falcon 9 has logged hundreds of successful landings since 2015; Blue Origin’s New Shepard has flown suborbital missions with booster recovery since 2015 as well.
China’s entry into this club is late but deliberate—the Long March 10B appears designed not merely to match existing technology but to integrate it into a broader national space infrastructure that includes the Tiangong station, lunar exploration plans, and a growing satellite constellation for communications and remote sensing. For Iran, which has pursued its own space launch vehicle program under the auspices of the Islamic Revolutionary Guard Corps, the Chinese model offers a path that Tehran has struggled to replicate.
Iranian officials have occasionally hinted at cooperation with China in space technology, though no concrete joint programs have been publicly confirmed. The Long March 10B’s success may deepen that interest, even as Western sanctions limit Iran’s access to critical components and expertise.
Military implications and dual-use concerns
Any discussion of reusable rocket technology inevitably touches on military applications. The same booster that places a satellite into orbit can, in principle, be adapted for other trajectories. The United States has long monitored China’s space program for signs of dual-use technology transfer, particularly to Iran and North Korea.
The Long March 10B, however, is a liquid-fueled vehicle—a design that is less suited to rapid, mobile launch than solid-fueled missiles but offers greater efficiency for heavy payloads. The first stage’s controlled descent and landing at a designated recovery site, rather than an ocean splashdown, suggests a level of precision guidance that has obvious parallels to reentry vehicle technology.
CASC has not commented on any military applications, and the rocket’s stated purpose remains commercial and crewed spaceflight. But the line between space launch and missile technology has always been thin, and China’s progress narrows it further.
What to watch next
The Long March 10B’s next flight will be closely watched—not just for technical performance but for cost data. If CASC can demonstrate reliable reusability at the projected 30% savings, the rocket could become a workhorse
