US Army Activates Laser Counter-Drone System Near El Paso Airport, Prompting Airspace Closure
The United States Army deployed an advanced laser-based counter-drone system in close proximity to El Paso International Airport on Wednesday, leading to a temporary shutdown of the surrounding airspace that lasted approximately seven hours. Military officials confirmed the deployment, citing a suspected cartel drone incursion as the primary catalyst for this defensive action.
Advanced Directed-Energy Weapon System Deployed
The system in question is known as LOCUST, which stands for Laser Optical Counter-UAS System for Tactical Use. Developed by defense contractor AeroVironment Inc., LOCUST represents a 20-kilowatt directed-energy weapon specifically engineered to neutralize unmanned aerial threats through concentrated light energy rather than conventional munitions.
According to Federal Aviation Administration records, authorities initially ordered a 10-day airspace closure in response to the security threat. However, this restriction was lifted within hours once the situation had stabilized and the immediate danger had passed.
Growing Drone Threat Along US-Mexico Border
Pentagon data reveals a staggering increase in drone activity along the southern border, with more than 1,000 drone sightings reported each month. Steven Willoughby, deputy director of the Department of Homeland Security's counter-drone program, testified before Congress in July that cartels employ drones on an almost daily basis for multiple illicit purposes.
Cartel drone operations include:
- Transporting narcotics across international boundaries
- Conducting surveillance of Border Patrol agents
- Monitoring critical infrastructure and security operations
Recent statistics indicate that during the last six months of 2024 alone, authorities detected more than 27,000 drones within 500 meters of the U.S. southern border, with the majority of these incursions occurring under cover of darkness.
Technical Specifications of the LOCUST System
The 20kW class Palletized HEL (Locust) represents a sophisticated directed-energy system compatible with Forward Area Air Defense Command and Control (FAAD C2) architecture. This modular system can operate either as part of the Forward Area Layered Integrated Defense System (FS-LIDS) or as a standalone unit with its own command and control capabilities.
The system incorporates multiple advanced components:
- Beam director for stabilization and precision aiming
- Multi-target infrared search-and-track capability
- Electro-optical tracking systems
- Gimbaled telescope and rangefinder
- Multiple camera payload options
BlueHalo, now integrated into AeroVironment, describes LOCUST as featuring a sensor-agnostic "plug-and-play" design that enables seamless integration with various sensor types and radio-frequency systems across multiple platforms.
How the Laser Counter-Drone System Operates
Unlike traditional air defense systems that rely on interceptor missiles or explosive munitions, LOCUST employs directed energy to heat and structurally compromise its targets. Once a drone is detected and tracked, the laser beam focuses on critical components such as the propulsion system or structural frame.
Sustained heating weakens or disables the drone, causing it to malfunction or fall from the sky. This engagement occurs without explosions, significantly reducing collateral damage risks in urban environments or near civilian infrastructure like airports.
The "Kill Chain" Concept and AMP-HEL Program
AeroVironment characterizes LOCUST as an end-to-end directed-energy "kill chain" that integrates the complete sequence from detection through neutralization. This comprehensive approach allows for rapid engagement of aerial threats without requiring multiple separate systems.
LOCUST is being fielded under the U.S. Army's Multi-Purpose High Energy Laser (AMP-HEL) prototyping program, which represents a strategic shift in defense planning toward mobile, tactically deployable systems. The program aims to transition directed-energy weapons from laboratory experimentation to operational battlefield capability.
Key advantages of laser systems like LOCUST include:
- Significantly lower cost per engagement compared to traditional missiles
- Rapid, near-instantaneous response to emerging threats
- Reduced collateral damage in populated areas
- Deep magazine capability allowing repeated firing without reloading
Strategic Implications and Future Applications
The deployment near El Paso International Airport marks an unusual instance of military-grade directed-energy technology being employed in proximity to civilian aviation infrastructure. This development underscores the growing intersection between border security, civilian aviation safety, and emerging drone threats.
Officials have indicated that the United States is increasingly seeking safe and cost-effective methods to counter drone proliferation, particularly around airports and during major public events. Security concerns are intensifying ahead of upcoming high-profile gatherings, including the FIFA World Cup and America250 anniversary celebrations scheduled for this summer.
As drone threats continue to expand, particularly from non-state actors and smuggling networks, laser systems like LOCUST provide a scalable defensive solution that can adapt to evolving technological challenges while minimizing risks to civilian populations and infrastructure.
