Chinese military researchers have developed a novel drone-mounted device capable of redirecting powerful ground-based laser beams, potentially transforming small unmanned aircraft into precise directed-energy weapons platforms, according to research published in the peer-reviewed journal Acta Armamentarii reports the South China Morning Post.
The breakthrough, led by associate researcher Li Xiao at the National University of Defence Technology’s school of optoelectronic science and engineering, circumvents the longstanding challenge of mounting high-powered lasers on small drones. Rather than carrying heavy laser generation equipment, the system uses a lightweight redirecting device that reflects ground-based laser beams onto targets.
The reported capabilities are substantial. The system allegedly can direct near-infrared laser beams at 1080 nanometers wavelength with an intensity of one kilowatt per square centimeter – sufficient to disable sensors, damage equipment, and cause severe injury. This represents an intensity 200 million times greater than the five-microwatt threshold capable of causing vision damage.
When evaluating these claims, several technical and practical considerations emerge. While the concept of using drones as laser reflectors is innovative, questions remain about targeting precision, atmospheric effects on beam coherence, and the system’s vulnerability to countermeasures. The research team’s paper suggests primary applications in disabling vehicles and sensors rather than as a anti-personnel weapon.
This development occurs amid growing international focus on counter-drone technologies and the broader evolution of military drone capabilities. The system’s ability to project substantial power from relatively small platforms could have significant implications for tactical drone operations and defense planning.
The technology’s emergence highlights ongoing advances in directed-energy weapons and raises new questions about drone warfare evolution. While technical details remain limited, the development warrants attention from defense analysts and Drone Industry observers as capabilities continue to expand beyond traditional reconnaissance and kinetic strike roles.
Regulatory frameworks governing such systems remain unclear, particularly regarding potential dual-use applications and international arms control implications. The technology’s development may accelerate discussions about appropriate limitations on drone-mounted directed energy weapons.
