US defense officials have long worried that China's Guowang satellite network might give the Chinese military access to the kind of ubiquitous connectivity US forces now enjoy with SpaceX's Starlink network. It turns out the Guowang constellation could offer a lot more than a homemade Chinese alternative to Starlink's high-speed consumer-grade broadband service. China has disclosed little information about the Guowang network, but there's mounting evidence that the satellites may provide Chinese military forces a tactical edge in any future armed conflict in the Western Pacific.
