The "Thousand Sails Constellation" plan initiated by Shanghai Spacecom Satellite Technology (SSST) is designed to develop a network of low Earth orbit (LEO) satellites that will provide near-global internet coverage, similar to SpaceX's Starlink. The recent launch of 18 LEO satellites marks the beginning of this ambitious plan, which is seen as a response to Starlink’s network of about 5,500 LEO satellites. The Chinese initiative highlights the strategic importance of controlling LEO satellites, not only for commercial internet services but also for potential military applications, as indicated by Chinese media linked to the People's Liberation Army (PLA).
