In a rare public disclosure published in July 2026 in the Chinese journal High Power Laser and Particle Beams, researchers from the National University of Defence Technology (NUDT) detailed a series of advanced pulsed-power devices built by China's military. The paper reveals that China's high-power microwave (HPM) weapons have reached an output of up to 100 gigawatts (GW) — a power level that, for context, exceeds the total electrical generating capacity of many countries.
The core engineering challenge in HPM weapons is that a single pulsed-power driver cannot independently produce sufficient energy because of insulation and material limitations. The NUDT team solved this by developing a system that synchronizes multiple compact pulse generators, combining their outputs into a single coherent beam. This approach — known as pulsed-power combining — is analogous to how multiple laser beams can be combined for higher intensity, but applied to the microwave spectrum.
The military implications are significant. At 100 GW, an HPM weapon can theoretically disable or destroy the sensitive electronics aboard satellites in low Earth orbit (LEO), including communications constellations. The system can also neutralize drone swarms, disrupt command-and-control networks, and disable adversary radar and communication systems — all without kinetic projectiles. Because microwave weapons travel at the speed of light and are invisible to the naked eye, they offer a fundamentally different engagement model from traditional missiles or bullets.
However, the technology is not solely about weapons. The same pulsed-power advances that enable 100 GW HPM systems have civilian applications in materials processing, medical isotope production, particle acceleration for scientific research, and even food sterilization. Directed-energy research has historically produced dual-use breakthroughs — the klystron and magnetron, developed for radar during World War II, later became the core of microwave ovens. The NUDT disclosure may similarly accelerate industrial and medical applications of pulsed-power technology.
The geopolitical dimension is equally important. The disclosure comes amid intensifying global competition in space-based assets and electronic warfare. The United States, Russia, and other nations also maintain HPM research programs, but public disclosures of this magnitude are rare. The paper signals that China views directed-energy weapons as a strategic priority, and the explicit mention of countering LEO satellite constellations — widely interpreted as a reference to systems like Starlink — underscores how space has become a contested domain.
Knowledge takeaway: China's NUDT scientists disclosed HPM weapons achieving 100 GW output via synchronized pulsed-power combining; the technology can disable satellites, drones, and electronic systems at the speed of light; the same pulsed-power advances have civilian applications in materials science, medicine, and particle physics; the disclosure reflects China's strategic prioritization of directed-energy and space warfare capabilities.
