U.S. Army Advances Next-Generation High-Energy Laser Weapons to Counter Drone Threats

The U.S. Army is actively advancing a new generation of high-energy laser weapons to address the threat posed by drones on the battlefield. Through its ongoing High Energy Laser (E-HEL) program, the Army aims to develop modular systems that can be transferred between different military vehicles to enhance aerial defense capabilities beyond specialized combat units. Directed energy weapons like E-HEL can destroy drones at a cost far lower than that of expensive kinetic weapons such as missiles. E-HEL is powered by electricity and can generate lethal high-energy laser beams, with a relatively low cost per shot against critical unmanned aerial system threats, and its ammunition can regenerate itself from the system's power supply.

Importance of the E-HEL Program

With scalable and cost-effective directed energy capabilities, the E-HEL program marks a significant step for the Army in providing scalable, economical, and adaptable directed energy capabilities. The Army's emerging concept focuses on decoupling laser weapon systems from specific installation vehicles. The Army hopes to develop modular systems that can be integrated into different platforms based on operational needs, rather than developing a dedicated laser-equipped vehicle for each mission. During a recent panel discussion at the Association of the United States Army (AUSA) annual meeting, it was revealed that the Army may soon integrate laser weapons onto multiple vehicles.

Major General Guy Yelverton, executive officer of the Army's Directed Energy Capability Program, explained that the program is exploring how future laser capabilities can be integrated into the Army's vehicle fleet.

This concept may allow laser systems to be installed on tactical vehicles, light multipurpose platforms, and other suitable military transport assets. It also facilitates the easier redeployment of weapon systems when vehicles require maintenance or operational priorities change. The program also aims to make the systems easier to operate, potentially allowing non-traditional air defense units to use laser weapons against incoming drones. The LOCUST series has already been explored in both vehicle-mounted and shelf configurations, with some early variants deployed to support U.S. operations at the southern border. The LOCUST X3 combines a laser projector with electro-optical and infrared sensors for target identification, tracking, and engagement.

Design of Modular Systems

Additional sensors, including radar and passive radio frequency detection equipment, can provide information to help guide the weapon against potential threats. The system is primarily designed to counter small unmanned aerial vehicles. Its relatively compact configuration makes it suitable for deployment on light tactical vehicles, although integrating it into smaller platforms poses challenges related to payload capacity, power supply, cooling, and overall system weight. The Army's larger goal is not just to acquire a new laser weapon but to establish a flexible architecture that can improve performance and reliability over time. In September, the U.S. Army announced it had awarded AeroVironment Inc. a Other Transaction Agreement for the production of the High Energy Laser program.

This is the Army's first production contract for a high-energy laser weapon system.

The E-HEL is designed using a modular open system approach, featuring 11 major interfaces and not locked to a single platform or vehicle. The system is intended to provide operational flexibility, capable of being deployed from fixed bases, semi-fixed tactical sites, and mobile combat vehicles, ensuring broad applicability within the operational spectrum. This approach will make it feasible to introduce cutting-edge technological capabilities and ongoing technical upgrades to meet emerging Army needs.

Impact of High-Energy Laser Weapons on Modern Warfare

The U.S. Army's initiative to advance high-energy laser weapon systems reflects the growing threat of drones in modern warfare. With a modular design, these systems can not only be flexibly transferred between different platforms but also reduce operational costs and enhance responsiveness. As technology advances, the reliability and performance of laser weapons will continue to improve, which is crucial for enhancing the Army's aerial defense capabilities. This strategy also demonstrates the Army's adaptability to future combat environments, especially in the face of evolving threats.
