Why Aircraft Carriers Are the Ideal Platform for Laser Weapons: Power, Space, and Strategic Defense in Modern Naval Warfare

The U.S. Navy has conducted the first-ever live-fire test of a laser weapon from an aircraft carrier, marking a significant step toward integrating directed energy systems into naval defense. The test took place aboard the USS George H.W. Bush (CVN-77) in October 2025, where a containerized 20 kilowatt Palletized High Energy Laser (P-HEL) system successfully tracked, engaged, and neutralized multiple target drones, including drone swarms.

The laser weapon system used in the test is based on the LOCUST Laser Weapon System from defense contractor AV and was on loan from the U.S. Army’s Rapid Capabilities and Critical Technologies Office (RCCTO). Photos of the system on the flight deck were published to the Defense Visual Information Distribution Service (DVIDS) on April 20, 2026, showing the palletized setup ahead of testing in the Atlantic Ocean.

AV officials confirmed that the live-fire test involved 17 drones and demonstrated the system’s ability to complete the full kill chain—detecting, tracking, and destroying targets in sequence. AV vice president for directed energy systems John Garrity stated that the test marked “a major milestone toward fielding operational directed energy capabilities across all domains and platforms.”

Advantages of Aircraft Carriers for Laser Weapons

Aircraft carriers offer distinct advantages for hosting laser weapons due to their substantial power generation and available space. Unlike smaller surface combatants such as Arleigh Burke-class destroyers, carriers do not face the same power or space constraints, allowing systems like the P-HEL to draw energy directly from the ship’s nuclear reactors without competing with other high-demand systems such as the AN/SPY-6 radar on Flight III destroyers.

Operational Context and Strategic Value

The test is particularly significant given the increasing threat posed by drone swarms to naval vessels. Aircraft carriers, as high-value assets at the center of carrier strike groups, are prime targets for asymmetric attacks involving drones and cruise missiles. Laser weapons offer a low cost-per-shot and deep magazine capacity, potentially allowing carriers to conserve limited kinetic interceptor stockpiles for higher-end threats while providing a sustainable layer of close air defense.

Challenges and Limitations

Despite the advantages, employing laser weapons on aircraft carriers presents notable challenges. Atmospheric conditions at sea—including water vapor, dust, salt aerosols, and temperature fluctuations—can cause beam scattering, diffusion, or energy loss, reducing effectiveness. Laser weapons require dwell time to neutralize targets, making them vulnerable to saturation attacks that could overwhelm the system through sheer volume of incoming drones.

Operational and Tactical Complexity

The dynamic environment of a carrier flight deck introduces further complexity. With frequent aircraft launches and recoveries, integrating a weapon that requires a stable, uninterrupted invisible beam demands meticulous deconfliction with friendly aircraft and sensors to avoid mishaps. Automated safety layers in systems like LOCUST help mitigate risks, but the potential for friendly fire remains a concern during high-intensity engagements involving drone swarms.

Broader Implications and Future Development

The successful test aligns with the vision of Chief of Naval Operations Adm. Daryl Caudle for a modular, containerized fleet capable of rapidly configuring capabilities like laser weapons, electronic attack systems, and drone swarms without lengthy integration processes. This approach mirrors ongoing efforts by contractors such as Lockheed Martin, which is developing a containerized version of its HELIOS laser system for naval use.

The Army currently fields at least four LOCUST systems on M1301 Infantry Squad Vehicles and Joint Light Tactical Vehicles through its Multi-Purpose High Energy Laser (AMP-HEL) initiative. The Marine Corps has also awarded a contract to AV for a LOCUST-equipped JLTV, though delivery status remains unconfirmed.

As the Navy continues to evaluate directed energy systems, the USS George H.W. Bush test demonstrates that laser weapons are a natural fit for large, power-rich platforms. However, their ultimate effectiveness will depend on how well they can function within the compressed, chaotic battlespace of a carrier strike group under combat conditions.
