US military to test laser weapons against drones for 365 days
Synopsis
Key Takeaways
The US military is set to launch a year-long operational trial of high-energy lasers and high-power microwaves designed to neutralise hostile drones, a senior Army official confirmed on 25 August. The pilot programme marks a significant step toward deploying directed-energy weapons as a reliable, cost-effective counter-drone solution at military installations.
What the Trial Involves
Brigadier General Matt Ross, director of Joint Interagency Task Force 401, said the systems would be stationed at a military installation and operated entirely by service members for 365 days. The goal is to assess real-world performance under sustained operational conditions — not just controlled laboratory settings.
'It's a directed energy pilot,' Ross said at a media roundtable that included officials from the Army, the Federal Bureau of Investigation (FBI), and the Department of Homeland Security (DHS). 'When we say directed energy, we use that term to be inclusive of all novel technologies, but what we're really focused on right now is high-energy lasers and high-power microwaves,' he added.
Key Questions the Pilot Will Answer
While laboratory tests have already confirmed that both laser and microwave systems can destroy or disable drones, Ross said the critical unknowns remain operational. 'We have a number of systems, and we've proven that the science works,' he said. 'But we need to figure out how to use them successfully in an operational context.'
The trial will evaluate power consumption, maintenance demands, operating costs, and the number of days each system remains mission-ready versus requiring repair. Officials will also assess when specialised technicians are needed, and whether the weapons can be operated without disrupting normal aviation activity around the base. 'I don't want to shut down the airspace as I use those systems,' Ross noted.
The Drone Threat Driving Urgency
The accelerating use of low-cost unmanned aircraft in conflicts — most visibly in Ukraine — has sharpened international focus on counter-drone technology. High-energy lasers can engage individual targets with precision, while high-power microwave systems can potentially disrupt the electronics of multiple drones simultaneously, offering a broader area-effect capability.
Steve Willoughby, a DHS official, acknowledged the dual-use nature of drone technology. 'Drones and the use of drones protect people, protect our assets, save lives, and really allow us to do more with less,' he said. 'On the counter side, it's about how we enable the good while preventing the bad.' He cited the FIFA World Cup as a case study, where authorities managed authorised media, delivery, and public-safety drones while enforcing strict flight restrictions around stadiums and critical infrastructure.
Broader Mission and What Comes Next
Joint Interagency Task Force 401 works with federal, state, and local agencies to protect military bases, public gatherings, and critical infrastructure. Its mandate spans drone detection, mitigation, explosives safety, forensics, intelligence, and investigations.
Findings from the year-long pilot will allow the military to directly compare the cost and effectiveness of directed-energy systems against conventional counter-drone methods, potentially shaping procurement decisions for years ahead.
