On July 10, the China Aerospace Science and Technology Corporation (CASC) successfully recovered a Long March 10B rocket booster using a specialized barge. This milestone marks the first time China has landed a reusable booster on a ship, utilizing a unique cable-based arresting system.
The Linghangzhe's Cable-Based Recovery Method
The China Aerospace Science and Technology Corporation (CASC) utilized a unique barge systeem known as the Linghangzhe to secure the Long March 10B booster. Unlike the landing legs used by other space agencies, the Linghangzhe employs a ground arresting cable mechanism similar to those found on aircraft carriers. This engineering choice allows the booster to be caught upon descent,which significantly reduces the overall weight of the spacecraft by eliminating heavy landing gear.
The inaugural flight took place at the Hainan International Commercial Aerospace Launch Center, where the liquid-fueled rocket, powered by seven oxygen-kerosene engines, demonstrated its ability to return to a precise maritime coordinate.. By removing the need for conventional legs, CASC is betting that it can enhance the long-term reusability and efficiency of its launch vehicles .
Closing the 8-Ton Payload Gap with SpaceX
The Long March 10B currently possesses a reusable payload capacity of 17 tons to low-Earth orbit, which is slightly behind the capabilities of the U.S.-based SpaceX. according to the report, SpaceX's Falcon 9 can deliver approximately 25 tons, leaving an 8-ton gap in lifting capacity between the two leading reusable systems. despite this difference, the successful recovery of the Long March 10B on its first attempt suggests a rapid mastery of complex recovery dynamics.
This achievement makes CASC only the third entity globally to successfully land a full-scale rocket booster on a recovery ship. While the payload capacity is currently lower, the precision of the first-attempt recovery indicates that China's state-backed aerospace program is accelerating its timeline to match or exceed Western commercial standards.
CASC, LandSpace, and the Race for State-Backed Dominance
The success of the Long March 10B is part of a broader strategic push involving a mix of state-affiliated and private Chinese firms. Entities such as the Shanghai Academy of Spaceflight Technology, LandSpace, and Space Pioneer are all competing to secure market share in the reusable rocket sector. This internal competition, fueled by government subsidies, is designed to lower launch costs and attract international satellite customers.
As reported, the Chinese government's ability to leverage state-owned enterprises provides a financial cushion that private U.S. firms do not have in the same way. This operational efficiency, combined with the innovative Linghangzhe recovery technology, could potentially shift the commercial space industry's center of gravity if other nations adopt cable-based recovery systems over traditional landing legs.
The Year-End Reflight and U.S. Export Restrictions
CASC has announced plans to refly the Long March 10B booster by the end of the year to prove the system's long-term viability. However , several critical questions remain regarding the global scalability of this technology. Specifically, it is unclear how CASC will navigate U.S. export restrictions on satellite technology, which may limit the types of international payloads the Long March 10B can carry regardless of its recovery success.
Furthermore, the source only provides the perspective of the successful recovery; it remains to be seen how the cable-arresting system performs under varied weather conditions or with heavier payload configurations. Whether the Linghangzhe system can maintain its reliability across a high volume of launches remains the primary technical hurdle for China's space ambitions.
