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.
The megaconstellation is managed by a secretive company called China SatNet, which was established by the Chinese government in 2021. SatNet has released little information since its formation, and the group doesn't have a website. Chinese officials have not detailed any of the satellites' capabilities or signaled any intention to market the services to consumers.
Another Chinese satellite megaconstellation in the works, called Qianfan, appears to be a closer analog to SpaceX's commercial Starlink service. Qianfan satellites are flat in shape, making them easier to pack onto the tops of rockets before launch. This is a design approach pioneered by SpaceX with Starlink. The backers of the Qianfan network began launching the first of up to 1,300 broadband satellites last year.
Unlike Starlink, the Guowang network consists of satellites manufactured by multiple companies, and they launch on several types of rockets. On its face, the architecture taking shape in low-Earth orbit appears to be more akin to SpaceX's military-grade Starshield satellites and the Space Development Agency's future tranches of data relay and missile-tracking satellites.
Guowang, or "national network," may also bear similarities to something the US military calls MILNET. Proposed in the Trump administration's budget request for next year, MILNET will be a partnership between the Space Force and the National Reconnaissance Office (NRO). One of the design alternatives under review at the Pentagon is to use SpaceX's Starshield satellites to create a "hybrid mesh network" that the military can rely on for a wide range of applications.
