Weeks after a military laser forced the sudden closure of airspace over El Paso, Texas, the Federal Aviation Administration has signed off on the weapon’s safety, declaring that the high-energy counter-drone system operating along the southern U.S. border does not pose undue risk to commercial aircraft.
The FAA and the Department of War (the recently rebranded Department of Defense) published a formal safety agreement in May 2026 after completing a joint assessment of the laser system. The agreement establishes coordination protocols requiring the military to notify the FAA before activating the weapon inside U.S. airspace, a step that was skipped during the incident that triggered the review.
The El Paso incident that started it all
In February 2026, U.S. Customs and Border Protection activated the anti-drone laser near Fort Bliss, Texas, after receiving Pentagon authorization. No one told the FAA. When the agency learned a directed-energy weapon was firing in the vicinity of commercial flight paths, it closed El Paso airspace and restricted commercial traffic in the area, a response the Associated Press described as unusually broad in scope.
The restrictions were lifted after what officials characterized as a communications breakdown was resolved. But the episode exposed a serious gap: the military had deployed a high-powered laser near one of the busiest border-region airports in the country without following the FAA’s existing notification process for outdoor laser operations, known as Form 7140-1.
Why a laser, and what it targets
The counter-drone system uses directed energy to disable unmanned aircraft operating near the southern border. The Department of War has described the threat as involving drones that cross into U.S. airspace in the border region, though neither agency has publicly detailed the specific types of unmanned aircraft the system is designed to engage. Directed-energy weapons offer certain advantages over kinetic counter-drone methods such as missiles or projectiles: they can be fired repeatedly without ammunition, they travel at the speed of light, and they reduce the risk of falling debris in populated areas. Those characteristics make lasers attractive for use near civilian infrastructure, but they also introduce hazards unfamiliar to aviation regulators, including the potential for beam energy to reach aircraft surfaces or cockpits.
Testing at White Sands
To build a data-driven foundation for the safety agreement, the Joint Interagency Task Force 401 (JIATF-401) and the FAA scheduled a joint counter-drone laser test at White Sands Missile Range for March 7 and 8, 2026. The test was designed to measure how laser energy affects aircraft materials, validate automated safety shut-off systems, and gather data relevant to aircrew eye safety.
The Department of War described the White Sands demonstration as directly intended to address the FAA’s concerns following the Fort Bliss episode. Neither agency has confirmed publicly whether the test took place as scheduled, and no post-test report or data summary has appeared in either agency’s public records as of May 2026. The safety agreement references the White Sands demonstration, but the extent to which test data informed the final determination versus pre-existing analysis is not specified.
What the agreement says
According to the FAA’s description of the assessment, the agencies evaluated both the physical risk of a laser beam striking an aircraft and the potential effects on pilots’ vision and onboard sensors. Their conclusion: commercial flights can continue using border-area routes while the laser is operational, provided the agreed-upon procedures are followed.
The system is configured so that its engagement envelope does not intersect with established flight corridors when safety controls are active, the FAA said. The agreement requires the military to formally coordinate with the FAA before activating the laser, replacing the ad hoc approach that led to the El Paso shutdown.
The specific safeguards, whether they rely on automated shut-off technology, geographic exclusion zones, real-time air traffic control coordination, or some combination, were not publicly disclosed.
What remains uncertain
The agreement answers the immediate question of whether the laser can coexist with commercial aviation, but it leaves several important gaps.
No named official from CBP or the Pentagon has publicly explained why the Fort Bliss laser was activated without FAA notification. Whether that reflected a policy gap, a procedural failure, or a deliberate decision to prioritize speed over coordination has not been clarified on the record. That distinction matters: it determines whether the new agreement fixes a systemic weakness or patches over a one-time lapse.
There is also no public accounting of how many times the laser has been used operationally since the El Paso shutdown, or whether the February episode was an early stumble in a rare program or part of a broader pattern of deployments along the border.
The long-term regulatory picture is similarly unresolved. The FAA’s existing laser notification process, Form 7140-1, was designed for civilian and commercial operations. Whether the agency plans to update that framework to account for military directed-energy weapons near civilian airports has not been announced. The current agreement covers the southern border, but similar drone threats could emerge near other busy flight corridors, and no public guidance addresses how the protocol would scale.
The agreement also does not resolve broader policy questions about how much risk is acceptable when integrating directed-energy weapons into domestic airspace. The FAA’s mandate is to ensure safety, while the Department of War is focused on border security and countering unmanned aircraft. How those priorities will be balanced if future assessments reveal trade-offs between maximum defensive effectiveness and maximum aviation safety is not addressed in the materials released so far.
What this means for travelers
For passengers and airline operators flying near the southern border, the practical effect is straightforward: the FAA has determined the laser system can operate alongside commercial aviation under defined conditions, and future disruptions should be more targeted and predictable than the sudden El Paso closure.
Travelers affected by any future airspace restrictions in the region should monitor FAA Notices to Air Missions (NOTAMs), which would reflect temporary closures or routing changes tied to counter-drone operations. Because the new agreement requires advance coordination, the kind of wide-area, no-warning shutdown that followed the Fort Bliss incident should not recur.
Still, the absence of published test data and detailed safeguards means the public is largely taking both agencies at their word. Until independent evaluations or more granular disclosures emerge, the evidence supports a narrow conclusion: the FAA and the Department of War have built a formal process to manage a specific high-energy laser along the southern border, and they assert that process is sufficient to protect passenger aircraft. Whether that framework proves durable, and whether it can serve as a model for future directed-energy deployments in American airspace, will depend on how transparently the government handles the next round of testing, incidents, or policy changes.
