The Pentagon and the Federal Aviation Administration will jointly test a high-energy laser system designed to shoot down unauthorized drones at White Sands Missile Range in New Mexico on March 7 and 8, 2026. The exercise, led by Joint Interagency Task Force 401, comes directly after a series of border-zone incidents in Texas where an uncoordinated military laser deployment forced the FAA to shut down airspace over El Paso for hours. The test is meant to prove that counter-drone weapons can operate without disrupting commercial aviation, a question that took on real urgency after last month’s chaos.
Texas Laser Incidents Forced the Issue
The New Mexico test did not materialize on a routine schedule. It grew out of a messy sequence of events near the U.S.-Mexico border in February. On February 27, a Pentagon-operated laser shot down a Customs and Border Protection drone in Texas, destroying a federal agency’s own aircraft in what appeared to be a coordination failure between military and civilian operators.
That incident was not isolated. The Defense Department had authorized CBP to use an anti-drone laser system along the border without first clearing the deployment with the FAA, the agency responsible for the safety of every aircraft in U.S. airspace. When the FAA learned what was happening, it abruptly closed El Paso-area airspace, grounding commercial flights and disrupting travel across the region. The closure lasted roughly eight hours before normal operations resumed, and airlines scrambled to reroute or delay departures while controllers verified that no aircraft would intersect the laser’s potential hazard zone.
The fallout was swift. Sen. Tammy Duckworth of Illinois, the ranking member of the Senate Aviation Subcommittee, called for a thorough, independent investigation into the February incidents. Her statement tied together the CBP drone shoot-down and the airspace closure as evidence of dangerous interagency breakdowns and demanded answers on how a military-directed energy weapon had been fielded near busy civilian air routes without a formal safety review. The political pressure, combined with the operational embarrassment, appears to have accelerated the Pentagon and FAA’s agreement to formalize testing before any further border deployments.
Officials familiar with internal planning told one national outlet that the Texas episode exposed gaps not just in procedures, but in basic technical understanding of how the laser might interact with avionics, satellite navigation, and pilot vision at various altitudes and distances. Those unknowns made it difficult for the FAA to quantify risk in real time, leaving airspace managers with little option but to shut everything down until they could be confident no passenger aircraft were at risk.
What the White Sands Test Will Measure
The two-day exercise at White Sands Missile Range is designed to answer a specific question: can a high-energy laser neutralize unauthorized drones without creating hazards for pilots, passengers, and navigation systems in the surrounding airspace? JIATF-401 and the FAA framed the test as addressing safe integration into the National Airspace System, the network of controlled and uncontrolled airspace that governs all flight in the United States.
U.S. Deputy Transportation Secretary Steve Bradbury told Reuters in an interview that the testing is necessary so the FAA can approve uses of the system. That framing is significant: it signals that the FAA currently lacks the data it needs to sign off on operational laser deployments, which means the Texas border use proceeded without the regulatory groundwork that would normally precede such activity. Bradbury suggested that only after structured testing will the agency be in a position to evaluate requests for future deployments case by case.
White Sands offers a controlled environment that the Texas border zone did not. The range sits in a remote stretch of southern New Mexico with restricted airspace already in place, allowing testers to fire lasers and track drone targets without risking interference with commercial flight paths. Engineers will measure how the beam scatters in different atmospheric conditions, how reflections behave around metallic structures, and what buffers are needed to ensure no stray energy reaches civil aircraft corridors above or nearby.
The FAA has prior experience conducting off-airport drone-related testing in New Mexico near Santa Teresa, where it worked with CBP and other partners on exercises that included objectives around interference with navigation systems. That earlier work, focused on detection and tracking technologies, gives the agency a baseline for evaluating how directed-energy weapons might interact with radar, GPS receivers, and communication links. At White Sands, officials plan to build on those findings by placing instrumented test aircraft and ground sensors in positions where they can detect any unintended effects from the laser firings.
According to planning documents described by defense officials, the scenario will involve multiple classes of drones flown at varying altitudes and speeds, some simulating hostile behavior such as loitering over restricted facilities or approaching runways. Safety observers from both agencies will monitor “kill chains” from detection to engagement, looking for points where miscommunication or latency could create confusion for air traffic controllers or pilots.
A Growing Drone Threat and Expanding Military Authority
The urgency behind these tests reflects a broader shift in how the Defense Department views small drones on U.S. soil. JIATF-401, the Pentagon’s lead organization for counter-drone operations, recently released updated guidance on countering drone threats in the homeland. That guidance describes the proliferation of weaponizable unmanned aircraft systems as a domestic security concern and outlines expanded roles and authorities for military and interagency responders, emphasizing rapid response to drones near critical infrastructure, military installations, and certain border sectors.
The legal foundation for these actions rests on 10 U.S. Code Section 130i, which authorizes the Defense Department to protect certain facilities and assets from unmanned aircraft. The statute defines which locations qualify as “covered facilities and assets” and sets limits on what actions the military can take, including detection, tracking, and, in some circumstances, destruction of drones that pose a threat. But the law also requires coordination with the FAA, a requirement that the Texas incidents suggest was not met, at least not in a way that satisfied aviation safety officials.
That gap between authority and execution is the central tension. The Pentagon has legal power to shoot down drones near sensitive sites. The FAA has legal responsibility to keep the airspace safe for everyone else. When those two mandates collide without prior coordination, the result is what happened in El Paso: an emergency airspace shutdown that rippled through airline schedules, stranded passengers, and raised uncomfortable questions about who is ultimately in charge when military operations intersect with civilian skies.
Transportation and defense officials say the White Sands exercise is meant to prevent a repeat. By mapping out safe operating envelopes for the laser (how high, how far, at what angles and power levels it can be used without endangering other aircraft), they hope to develop standard procedures that can be applied to future deployments along the border or near other critical facilities. Those procedures could include mandatory notification timelines, pre-defined “no-fly” boxes, and protocols for temporarily rerouting air traffic during high-risk operations.
Still, the test underscores how quickly the drone threat has outpaced existing regulatory frameworks. Small unmanned aircraft are cheap, easily modified, and increasingly capable of carrying surveillance gear or improvised weapons. For border agents and military planners, directed-energy systems promise a way to defeat those threats without firing bullets or missiles that could endanger people on the ground. For aviation regulators, the same systems represent a new class of hazard that must be understood and contained before they can be allowed anywhere near busy air corridors.
Whether the White Sands results will be enough to satisfy skeptical lawmakers remains to be seen. Duckworth and other members of Congress have signaled that they want not just technical data, but also clearer lines of accountability when federal agencies operate powerful new weapons inside the United States. The upcoming report from the Texas investigation, combined with findings from the New Mexico test, will likely shape how, and how quickly, the Pentagon’s counter-drone lasers move from experimental ranges to the complex reality of the border.
