A spacecraft built to service satellites is also a weapon, because the same robotic arm that refuels one can disable one.

If a Chinese spacecraft can dock with a friendly satellite to refuel, repair, or transport it, the same robotic arm can also disable a US satellite’s solar panels and antennas. Alternatively, China can use these spacecraft to tow satellites into locations where they can, at best, only sub-optimally perform intended duties such as early warning, surveillance, or geolocation.
