U.S. Tests High-Energy Lasers and Microwaves for Counter-Drone Defense

The U.S. Department of War has chosen four directed-energy systems for a pilot program aimed at countering unmanned aircraft systems (UAS). This initiative, mandated by the Fiscal Year 2026 National Defense Authorization Act, will test high-energy laser (HEL) and high-powered microwave (HPM) technologies in operational settings. The selected systems include AeroVironment’s Palletized High-Energy Laser, Epirus’ Leonidas High-Powered Microwave, Kord’s Firefly High-Energy Laser, and Boeing’s Compact Laser Weapon System.

U.S. Army Brig. Gen. Matt Ross, director of Joint Interagency Task Force 401 (JIATF-401), emphasized that these technologies are part of a layered defense strategy rather than standalone solutions. The pilot program will evaluate their performance, costs, and integration with existing counter-UAS capabilities. JIATF-401 is collaborating with the Federal Aviation Administration (FAA), U.S. Northern Command, and military services to ensure safety and coordination.

The U.S. effort aligns with global trends, as militaries explore combined defenses against drone swarms. Recent Chinese military drills demonstrated the use of lasers, high-power microwaves, interceptor drones, and anti-aircraft guns to disrupt drone formations. The U.S. plans a directed-energy shoot-off at Dugway Proving Ground in December to assess additional HEL and HPM systems for potential deployment.
