High‑energy laser weapons (HELs) are moving rapidly from experiments and prototypes toward operational military deployment. HEL weapons function by directing powerful laser beams onto a target until it is neutralized by structural failure or destruction of sensors. At present, Israel and China are leading the HEL arms race, with likely deployment of HEL weapons this year. As armed forces adopt and adjust to the presence of HEL technology, laser weapons are unlikely to be decisive in future conflicts. ConclusionHigh‑energy laser weapons are no longer a science fiction fantasy.
