While the British Navy takes up to six years to build a single 8,500-ton anti-missile destroyer like the Type 26, the United States Army has put the AMP-HEL laser system, developed by AeroVironment, to a safety test at the White Sands Missile Range in New Mexico. This system is capable of downing enemy drones for a fraction of the cost of a conventional missile, with a continuous 50-kilowatt beam fired in fractions of a second. The Federal Aviation Administration approved the equipment’s automatic shutdown protocol after a commercial plane unexpectedly crossed the firing zone during the test conducted between March 7 and 8, 2026. As detailed by the specialized portal DefenseScoop, the event marked the first joint test between the Pentagon and FAA to validate the safe operation of directed energy weapons in U.S. airspace subject to civil air traffic.
The commercial plane incident was cited by military officials themselves as practical proof of the effectiveness of the onboard safety system in the AMP-HEL. When the radar coupled to the laser detected the aircraft entering the exclusion envelope defined by the FAA, the shot was canceled in fractions of a second, without any human intervention, keeping the plane and its passengers completely safe throughout the event.
The AMP-HEL had already been operating in active protection mode at sensitive points along the U.S.-Mexico border since February, with the direct mission of downing suspicious drones linked to drug trafficking and smuggling networks. The FAA’s formal approval now allows operational use within the continental United States, outside military bases.

Why a 50-kilowatt laser downs drones for dollars per shot
Traditional anti-aircraft defense systems against drones rely on interceptor missiles that cost between 250,000 and 1.5 million dollars each, depending on the model. When an adversary launches swarms of cheap drones, manufactured for less than a thousand dollars each, the economic equation becomes unsustainable for any armed force trying to respond with conventional weaponry.
High-energy lasers offer an almost definitive mathematical solution to this problem. The marginal cost of each shot is only the electricity needed to generate the beam, estimated at a few dollars per engagement, compared to hundreds of thousands of dollars for traditional missiles. Additionally, the loaded clip of shots is virtually unlimited as long as there is energy available in the system.
Researchers find that the more the Pentagon validates the use of high-energy lasers in real operational environments, the faster the American military doctrine incorporates the concept of continuous beam armor, informally known as a laser dome, as a complement or partial substitute for systems like Patriot, NASAMS, and THAAD in specific scenarios.
The context of increasing pressure on U.S. air defense
The recent surge in American investments in directed energy weapons stems directly from the episodes of war in Ukraine since 2022 and the Iranian attacks against Israel in 2024, which demonstrated the devastating power of coordinated swarms of cheap drones against conventional defenses. The American Navy had already developed maritime versions in projects like HELIOS and ODIN, but the recent leap is towards mobile land systems on an industrial scale.
According to coverage by Military Times on the Pentagon’s plans, the concept of a laser dome for domestic U.S. air defense has evolved rapidly over the past two years, with the Secretary of Defense establishing five pilot bases that will receive directed energy weapons permanently as part of continental defense.
The AMP-HEL is part of the family of four 50-kilowatt DE M-SHORAD systems already delivered to the Army, mounted on Stryker military vehicles and operated in coordination with mobile search radars. Integration with the Army’s conventional command and control network allows automated response in fractions of a second against detected aerial threats.
How the Pentagon-FAA agreement signed in April works
The formal signing of a security agreement between the Pentagon and the FAA, announced on April 13, 2026, establishes the national protocol for the operational use of high-energy laser weapons in proximity to civil air traffic. The document provides for temporary exclusion zones coordinated in real-time, with military bases informing the FAA before any test or operation involving high-power beams.
The agreement also regulates the use of high-energy lasers in night training, in the operation of protecting sensitive bases, and in the defense of moving military convoys. This last category is considered the most critical operational application of the AMP-HEL, especially on routes transporting sensitive material within U.S. territory.
According to the publication DefenseScoop on the Pentagon-FAA agreement, the document allows significantly faster deployment of lasers in sensitive civilian locations, shortening the regulatory process that previously could take months to authorize each specific operation in controlled airspace.
Who produces, who operates, and who will inherit the technology
AeroVironment, a Californian company founded in 1971 and historically associated with the Switchblade drones used by Ukraine, is the main manufacturer of the AMP-HEL system after its acquisition of the BlueHalo division in February 2025. The operation consolidated the company as one of the largest American suppliers of autonomous land and air weapons in related segments.
The American Army is the current main operator, with four units in the field since 2024 and eight more ordered for delivery throughout 2026. The United States Navy is also evaluating an adapted version for use aboard frigates and destroyers, in a separate project known as Helios Plus, with operational tests scheduled for 2027.

What still separates AMP-HEL from massive use in real combat
Despite rapid advances, directed weapons specialists warn that 50-kilowatt laser systems still have concrete limitations in adverse weather. Heavy rain, dense fog, low clouds, and sandstorms absorb or diffuse the high-energy beam, significantly reducing effectiveness against targets at distances greater than a few kilometers.
To overcome these limitations, the U.S. Army itself issued a Request for Information in November 2025 for the next generation of weapons, called the Enduring High Energy Laser, with power between 250 and 300 kilowatts. These more powerful systems promise to operate effectively even in adverse weather conditions and hit larger aircraft at extended ranges.
On the other hand, the AMP-HEL already fulfills a clear operational role within its specific niche, downing light class 1 and 2 drones in dry and clear environments with satisfactory reliability. The combination of extremely low marginal cost per shot and continuous availability makes it a valuable tactical tool in patrol and point defense scenarios.
