US Space Force's counterspace warning shows the satellites a Taiwan fight depends on are now targets

On Oct. 13, 2026, the US Space Force's Space Systems Command published a threat assessment saying China and Russia have fielded counterspace weapons that can jam communications, disrupt ground-control networks and damage or destroy satellites. The command described China as the pacing long-term competitor and Russia as the more immediate threat, and stressed that US forces depend on space for missile warning, tracking, navigation, logistics and secure communications.

The assessment put numbers on China's build-up. According to the command, China's presence in orbit has grown by 667 percent over the past decade to more than 1,300 satellites, and from January to November 2025 it carried out 70 launches carrying 319 payloads. It also uses at least 10 satellites to watch and identify other objects in orbit. An intelligence official at the command said China's funding and pace of experimentation put it closer than Russia to challenging US superiority in space.

The report also traced China's weapons record. Beijing destroyed a defunct weather satellite with a ground-launched missile in 2007, and the command said it now has an operational anti-satellite system aimed at low Earth orbit and is believed to be pursuing weapons that can reach geosynchronous orbit, where many warning and communications satellites sit. Both China and Russia have deployed satellites able to perform complex manoeuvres and close approaches to other spacecraft.

The argument

For Taiwan, the significance lies in the list of services under threat. Missile warning, tracking, navigation and long-haul communications are exactly what US forces would need to operate across thousands of kilometres of ocean in a Taiwan crisis. The assessment implies that planners should no longer assume those services will be fully available. The practical question is less how many satellites the United States and its partners own than how well their networks can keep working while some of them are jammed, blinded or lost. The same test applies to Taiwan's own satellite and communications projects, which will be judged by how well they survive interference rather than simply by whether they reach orbit.

Evidence and constraints

The command stressed that an attack does not need to destroy a satellite to stop it from being useful. Jamming, spoofing and cyber intrusions can disrupt spacecraft, their links and the computers that control them, while lasers, high-powered microwaves and orbital weapons can cause temporary or permanent damage. It said Russia is developing a satellite meant to carry a nuclear weapon for an anti-satellite role, and that Moscow has warned commercial satellites used for military purposes could become targets.

The cost of disruption would not be limited to the military. The command cited a US Office of Space Commerce estimate that a GPS outage could cost about one billion dollars a day, or up to 45 billion dollars over 30 days during key planting periods. In response, it said, the Space Force is adding anti-jam technology and protective software, shortening the time needed to prepare satellites for launch, and spreading capabilities across larger constellations so that no single satellite is decisive.

The assessment has limits as evidence. It is a public summary that offers scale rather than detail, and it says nothing about how the People's Liberation Army would sequence counterspace attacks in a Taiwan campaign. Satellite counts also measure quantity, not capability. Still, China's investment in satellites that track other objects in orbit matters, because knowing where an adversary's spacecraft are is the first step toward targeting them.

What could change

Several developments would show whether the threat is outpacing US adaptation. One is evidence of Chinese tests of weapons able to reach geosynchronous orbit. Another is more close-approach manoeuvres near US or allied satellites. On the other side of the ledger, the speed at which the Space Force fields larger, more resilient constellations and faster launch preparation will decide whether losing individual satellites becomes an inconvenience rather than a blinding blow. Allied steps would count as well, if partners add satellites and ground links that remove single points of failure.

Why it matters

Much of the deterrence picture around Taiwan rests on the assumption that the United States can see, communicate and navigate across the western Pacific. The Space Systems Command assessment is a reminder that China has been building the means to contest that assumption, not just to match US satellite numbers. How quickly Washington and its partners make their space networks harder to blind may matter as much to a Taiwan contingency as the ships and aircraft that depend on them.
