Anti-drone lasers used near the southern border by the U.S. military and Homeland Security to combat cartel drones are safe and shouldn’t necessitate airport closures, the Federal Aviation Administration announced Friday after a review prompted by airspace closures in Texas earlier this year.
The FAA and Defense Department have signed an agreement outlining the safety precautions that they say will protect travelers anytime these lasers are used, but their statement didn't spell out what those safeguards will be.
The FAA didn’t immediately respond to questions seeking more details about the agreement.
In early February, the FAA closed the airspace around the El Paso airport for several hours after another agency used a counter-drone laser without notifying the aviation safety regulator. That left many travelers scrambling to find new flights. A second, more limited airspace closure later that month followed the military shooting down a drone owned by U.S. Customs and Border Protection.
A demonstration of the lasers conducted last month at the White Sands Missile Range in New Mexico convinced the FAA that they can be used safely.
"We will continue working with our interagency partners to ensure the National Airspace System remains safe while addressing emerging drone threats,” FAA Administrator Bryan Bedford said in a statement.
Drones are commonly used along the border by Mexican cartels looking to deliver drugs or surveil officers. Officials told Congress last summer that more than 27,000 drones were detected within 1,600 feet (500 meters) of the southern border in the last six months of 2024.
The use of armed drones regularly carry out devastating attacks in the Ukraine and Iran wars highlights the threat.
Lawmakers in Congress said they are glad to see the agencies working together better now. But Democratic senators who raised questions after the anti-drone laser uses in February say they need detailed answers before they can be sure the lasers are safe. The FAA has not yet held a briefing for Congress.
“It is absolutely critical that meaningful interagency collaboration continues — the FAA must be at the table whenever any counter-UAS (Unmanned Aircraft System) is deployed that could impact the safety of our national airspace,” said Rep. Rick Larsen, who is the ranking Democrat on the House Transportation and Infrastructure Committee.
In the second incident, the military used the laser to shoot down a “seemingly threatening” drone flying near the U.S.-Mexico border on Feb. 26. It turned out the drone belonged to Customs and Border Protection, lawmakers said.
That led the FAA to close the airspace around Fort Hancock, about 50 miles (80 kilometers) southeast of El Paso.
The Trump administration has said it was working to halt an incursion by Mexican cartel drones. U.S. Army Brigadier General Matt Ross said that this agreement will allow the use of the most advanced tools to defend the homeland.
“By working hand-in-hand with the FAA and our interagency partners, the Department of War is proving that these cutting-edge capabilities are safe, effective, and ready to protect all air travelers from illicit drone use in the national airspace,” Ross said.
The U.S. government has handed out more than $250 million to help states prepare to respond to drones before hosting World Cup matches and celebrations planned this summer for the country's 250th birthday.
Another $250 million in grants will be awarded later this year to strengthen the nation’s drone defenses.
