South Korea Fields Cheongwang Laser to Down Drones for $1.50

The brutal math of modern drone defense

Air defense has an economic problem: cheap drones cost thousands, while interceptor missiles cost millions.

Modern conflicts have laid bare an unsustainable asymmetry in air defense. Militaries regularly expend interceptors costing several hundred thousand to several million dollars each to swat away mass-produced attack drones that cost a fraction of that figure. South Korea's answer is Cheongwang, developed jointly by Hanwha Systems and the state-run Agency for Defense Development.

Rather than carrying an expendable payload, the 30-kilowatt-class weapon focuses high-intensity thermal energy directly onto a target. Sustained heat compromises the structural integrity of the drone or detonates its onboard electronics and fuel. As long as the platform has access to steady electrical power and active cooling, its magazine is essentially limitless.

Cheongwang laser weapon: specs, power and cost

Proven in live-fire trials

Cheongwang entered service following the Republic of Korea Army's TIGER+ Future Warfare Integrated Combat Exercise on October 14, 2026. In front of roughly 500 military officials, the system engaged and destroyed three separate drones without a miss.

That demonstration followed an earlier trial where Hanwha showcased an even heavier 50-kilowatt Laser Armored Vehicle, which neutralized four drones and two uncrewed aircraft in rapid succession. Hanwha is targeting that heavier, mobile variant for international export, recently presenting the hardware at the MSPO defense exhibition in Poland as global interest surges in field-ready unmanned defenses—paralleling how robotics innovation is leaping ahead with platforms like the Unitree H2-X bodyguard robot.

Real-world limits of laser air defense

The $1.50 operating cost makes for a stunning headline, but firing energy is only a baseline figure. Total ownership overhead includes cooling system wear, optical maintenance, generator fuel, and hardware depreciation over thousands of operational hours.

Tactical limitations remain as well. Directed energy weapons demand clear lines of sight; heavy fog, dense smoke, or torrential rain scatter and degrade the beam. Furthermore, a laser can only engage one target at a time, requiring several seconds of dwell time on each airframe. A high-volume saturation swarm could overwhelm a solitary laser battery, meaning systems like Cheongwang will serve alongside traditional kinetic batteries rather than replacing them outright.

Availability and export prospects

Cheongwang is currently exclusive to the Republic of Korea Army, but Hanwha Systems is aggressively pitching its directed energy platforms to allied foreign militaries. The company displayed its 50kW mobile prototype in Poland to court European defense buyers facing urgent low-altitude drone risks.

Allied nations are working on parallel timelines. The UK is actively readying its own DragonFire directed-energy system for naval deployment on Royal Navy destroyers, while the US military continues field evaluations of mobile laser prototypes.

Directed energy is no longer laboratory science fiction. By putting Cheongwang into uniform, South Korea has crossed the threshold from experimental trials to real-world operational doctrine.
