Recent disclosures about China's purported in-orbit servicing operations have intensified a quiet revolution in space, where the mechanics of satellite sustainment are swiftly becoming the frontline of great-power counterspace rivalry.

This month, the South China Morning Post (SCMP) reported that Chinese researchers claim the country carried out a pioneering in-orbit refueling operation on a high-altitude navigation satellite, though orbital tracking data raise doubts about whether the mission occurred, according to recent scientific papers and satellite specialists.

Studies by the state-backed Deep Space Exploration Laboratory and the Chinese Academy of Sciences assert that the servicing spacecraft Shijian-25 transferred 142 kilograms of propellant to the BeiDou-2 G7 satellite in February 2025, extending the navigation orbiter's operational life by eight years.

While orbital refueling could significantly cut replacement costs and bolster constellation resilience for civilian and military guidance, the technology has stoked alarms in the US, where US Space Command officials warn that space-based replenishment could provide an adversary a tactical maneuvering edge during orbital conflict.

However, Western orbital tracking records compiled by the US Space Force contradict the claimed rendezvous. Independent astrophysicist Jonathan McDowell noted that BeiDou-2 G7 and Shijian-25 remained separated by roughly ten longitudinal degrees in geostationary orbit during early 2025, concluding that the drift rates make an undetected docking physically implausible unless tracking networks misidentified the target objects.

Emerging in-orbit refueling and autonomous proximity operations are fundamentally transforming orbital warfare from a doctrine of static endurance into an active, maneuvering gray zone contest between the US and China.

Although it is unclear whether China accomplished in-orbit refueling, the feat – if achieved – carries profound tactical implications. As Paul Szymanski and Calogero Bonasia mention in a July 2026 Proceedings article, a satellite with a 15-year operational lifespan carries only enough onboard propellant for routine station-keeping and end-of-life deorbit maneuvers, leaving large evasive burns to drain this fixed reserve rapidly.

Because evasive burns shorten operational lifespans, an aggressor need only feign an interception to force defensive displacement, Szymanski and Bonasia explain. Even if the defender avoids physical impact, the aggressor permanently degrades its operational reserve.
