**Deck**: A new Chinese defense study describes high‑power microwave weapons reportedly capable of generating up to 100 gigawatts to disable low Earth orbit satellites, including Starlink, at far lower cost than traditional anti-satellite missiles. If developed and deployed, such systems could give Beijing new tools to threaten the space infrastructure that militaries, economies and civilians now rely on.

China is openly exploring ways to knock satellites out of a war without firing a single missile, and the numbers now being discussed are hard to ignore.

A new Chinese defense study, summarized on 11 July, describes high‑power microwave (HPM) weapons capable of generating up to 100 gigawatts of power, with the stated goal of disabling or damaging low Earth orbit satellites such as those in the Starlink constellation. The authors argue that such systems could achieve effects at a fraction of the cost of conventional anti‑satellite (ASAT) weapons, which typically rely on expensive interceptors or co‑orbital platforms.

The study is not an official deployment announcement and its claims cannot be independently verified. But the fact that such ideas are being articulated in a formal Chinese defense context will reverberate far beyond the laboratory. Militaries and commercial operators have grown used to thinking of HPM threats at the tactical level – frying a radar, blinding a drone swarm, or knocking out a command post. This research suggests Chinese planners are thinking at orbital scale, about the hundreds or thousands of small satellites that now anchor everything from precision targeting to broadband internet.

For civilians, the satellite layer is easy to forget until it fails. Navigation apps, weather forecasts, crop monitoring, transoceanic flights and financial transactions all rely, somewhere in their chain, on data relayed from low Earth orbit. Starlink and similar constellations have turned that dependence into a real‑time lifeline in conflict zones, providing resilient communications in Ukraine and other contested theaters. A state‑level capability to systematically degrade those systems with directed energy would move critical civilian infrastructure much closer to the line of fire.

For militaries, the stakes are even sharper. Western forces increasingly assume that constellations like Starlink can backstop or supplement traditional military satellites, making their command-and-control and battlefield intelligence more survivable. If Beijing could field ground‑based or airborne HPM systems that temporarily disable or damage clusters of these satellites, it would gain a powerful asymmetric tool in any confrontation over Taiwan or in other regional flashpoints. Even intermittent disruption could complicate logistics, targeting, and alliance coordination.

Strategically, the study feeds into a broader competition over how to wage war in space without creating the long‑lasting debris that kinetic ASAT tests produce. China, the United States, Russia and others have all experimented with non‑kinetic means of interference, from jamming and spoofing to laser dazzling. HPM weapons fit neatly into that toolkit: they promise reversible or semi‑reversible effects, deniability, and lower per‑shot cost compared with launching missiles into orbit.

Yet the very features that make HPM attractive as a military instrument also raise risks of miscalculation. Attributing electromagnetic interference in space is technically complex and politically contentious. If a satellite network starts failing during a crisis, victims may struggle to distinguish between technical faults, solar activity, and hostile HPM attack. That ambiguity increases the danger that states might respond to perceived attacks in space with cyber strikes, sanctions or even conventional force on Earth.

The broader insight is that space security is no longer only about debris and missiles; it is increasingly about who can reach into the electromagnetic guts of orbiting infrastructure at will. That shift blurs the boundary between peacetime competition and wartime attack.

The next indicators to watch will be Chinese patent filings, test‑range activity, or procurement linked to high‑power microwave generators and large‑aperture antennas, as well as changes in U.S. and allied funding for satellite hardening and resilience. Any move by major powers to codify norms against HPM use in space – or, conversely, to publicly demonstrate such capabilities – will signal how quickly this shadow contest is moving from theory to practice.
