China unveils a directed energy weapon worthy of Star Wars 💥

Directed energy weapons, such as those using lasers or microwaves, are not a new concept. Their strength lies in their ability to disrupt or destroy electronic systems without the need for ammunition. Less costly and more efficient in some situations, these technologies open new strategic pathways.


The system developed by Chinese scientists is based on seven vehicles equipped with microwave emitters. From dispersed locations, these devices produce beams that converge into a single, unprecedentedly powerful one. A technique that evokes the superlaser of the Death Star in the Star Wars saga, though here, the targets are satellites or electronic equipment.

Achieving this perfect convergence is no small feat. Each vehicle must be positioned with millimeter-level precision, and synchronizing the beams requires an accuracy of 170 picoseconds (or 0.00000000017 seconds). This challenge was met thanks to the use of integrated laser devices and fiber optics.

To guarantee such precision, researchers also relied on the BeiDou satellite navigation system. This system had to be supplemented with even finer laser measurements, ensuring impeccable alignment of the beams.

The first tests indicated that this weapon could disrupt signals from U.S. GPS satellites, thus depriving some equipment of their navigation capabilities. Beyond direct military applications, this technology could also be used for training, simulation, or technological experimentation.

One of the key strengths of this system is its operating cost. Powered by a simple electrical source, this weapon can fire almost unlimitedly, offering an alternative to conventional ammunition. However, the researchers remain cautious about its use. Although promising, this innovation is not yet ready to be deployed on a large scale. Details about its real power or possible weaknesses remain undisclosed.

In a context of intense technological competition, this advancement positions China as a major player in the field of directed energy weapons. A technology that, while it may not destroy planets like in the movies, could very well redefine the rules of space defense.

What is a directed energy weapon?

A directed energy weapon (DEW) is a system that uses concentrated energy beams, such as lasers or microwaves, to neutralize or destroy targets. Unlike conventional weapons, it does not require physical ammunition.

Its principle is based on emitting waves or rays capable of disrupting electronic systems, jamming communications, or damaging mechanical structures. The energy is produced by an electrical or chemical source.

These weapons offer a strategic advantage: they are fast, precise, and economical. Their development is booming, particularly for military or space applications.

While promising, DEWs present technological challenges. They require high power, great precision, and robust systems to operate in hostile environments.
