Why is the U.S. government exploring using high-energy lasers near the border?

The unexpected and yet short-lived formation ban adjacent El Paso this week stemmed from disagreements wrong the national authorities implicit the use of a high-energy laser limb system to instrumentality down drones, aggregate sources told CBS News. After grooming by the U.S. military, Customs and Border Protection utilized a palletized high-energy laser strategy earlier this week, adjacent though the Federal Aviation Administration inactive has information concerns, according to sources who were granted anonymity due to the fact that they are not authorized to talk connected the matter. 

The strategy CBP utilized has been deployed overseas, according to 2 of the sources, but had not been considered for regular home usage until recently. The strategy works by detecting an aerial threat, emitting a laser beam that tin rapidly zero successful connected the target, similar a drone, and the beam's vigor damages oregon disables the object. 

High-energy lasers are 1 of respective systems the authorities could usage to antagonistic drones. 

"The laser, of course, is fundamentally instantaneous, and truthful it's comparatively casual for thing that's doing the velocity of airy to deed precisely the constituent connected the entity that it wants to do," said Tom Karako, a elder chap and the manager of the Missile Defense Project astatine the Center for International and Strategic Studies.

After Wednesday's formation regularisation was lifted, Transportation Secretary Sean Duffy said "the menace has been neutralized" by the FAA and praised the Pentagon, which helium said "acted swiftly to code a cartel incursion." But the Pentagon said it had thing to adhd erstwhile asked erstwhile oregon however the menace was eliminated. 

While CBP thought it was targeting overseas drones with the high-energy laser, it turned retired to person taken down astatine slightest 1 enactment balloon, aggregate sources told CBS News.

Drones adjacent the borderline are not caller and person been a dependable occupation implicit respective years, peculiarly those utilized by cartels.

"The cartel drone occupation is pervasive crossed the U.S. confederate border," according to Austin Doctor, who is an subordinate prof astatine the University of Nebraska astatine Omaha and the manager of strategical initiatives astatine the National Counterterrorism Innovation, Technology, and Education Center. 

The cartels and affiliates are chiefly utilizing drones for surveillance purposes "to enactment their different amerciable transgression activities, including smuggling of narcotics, smuggling of persons, firearms, and different illicit goods," Doctor told CBS News. 

They person not utilized weaponized drones wrong the U.S., helium said, but are utilizing them wrong of Mexico to people rival cartels, prompting fears they could yet commencement to usage the drones to endanger U.S. unit oregon infrastructure. 

The enactment adjacent the border, combined with the mysterious sightings adjacent subject installations, similar Joint Base Langley-Eustis successful Virginia successful 2023 and Joint Base McGuire-Dix-Lakehurst successful New Jersey successful 2024, contributed to the Pentagon's establishment of a associated task force to antagonistic drones. 

The task unit coordinates betwixt national agencies connected what authorities to usage successful circumstantial scenarios and however to mitigate immoderate menace from drones.  

The task unit is "doing large things," said retired Air Force Gen. Glen VanHerck, who served arsenic the commandant of U.S. Northern Command and NORAD from 2020 to 2024. 

"But there's truthful overmuch much to beryllium done," VanHerck said successful a telephone interview. "They request to beryllium empowered to get the close argumentation successful spot for who defends what circumstantial captious infrastructure with what circumstantial capability," helium said. "And the challenges go ensuring you're capable to support portion besides maintaining information of formation for wide and aviation craft and the nationalist successful general, depending connected what capableness you utilize to prosecute the threat." 

There are a assortment of capabilities "but nary metallic slug for countering drones," VanHerck added. 

He favors a layered strategy of defence with a instauration of vigor frequence cyber techniques that tin disrupt and instrumentality implicit the drone to bring it down safely. According to VanHerck, tract acquisition from astir the satellite shows that implicit 80% of drones encountered are commercialized and tin beryllium brought down with this benignant of technology. 

Other layers would trust connected antithetic systems that could see high-energy lasers. 

Karako of CSIS said defending the confederate borderline from drones is 1 portion of the larger puzzle that President Trump's Golden Dome inaugural is astir — to support the homeland from each aerial and rocket threats. 

"Maybe the acquisition present ought to beryllium that this large effort, this large inaugural coming down the tube that is called Golden Dome volition necessitate and unit america retired of necessity to person amended connection and amended coordination betwixt the precise indispensable FAA relation for aerial postulation power and aerial postulation management, the coordination betwixt the FAA relation and the DOD nationalist information function," Karako said.
