The Air Force Research Laboratory (AFRL) has demonstrated its high-power microwave counter drone weapon, the Tactical High-power Operational Responder (THOR), as it engaged a swarm of targets at Chestnut Test Site, Kirtland Air Force Base.

“The THOR team flew numerous drones at the THOR system to simulate a real-world swarm attack,” said Adrian Lucero, THOR Program Manager at AFRL’s Directed Energy Directorate. “THOR has never been tested against these types of drones before, but this did not stop the system from dropping the targets out of the sky with its non-kinetic, speed-of-light High-Power Microwave, or HPM pulses.”

Capt. Eric Plummer, a test engineer with AFRL’s Directed Energy Directorate, operated the THOR system and was responsible for aiming the THOR system at the swarm.

“THOR was exceptionally effective at disabling the swarm with its wide beam, high peak powers and fast-moving gimbal to track and disable the targets,” commented Lucero.

As the dangers from drone swarms evolve, leaders from across the Department of Defense are working closely to explore different technologies like directed energy to support the needs of the warfighter in the future against such threats.

“THOR was extremely efficient with a near continuous firing of the system during the swarm engagement,” said Capt. Tylar Hanson, THOR Deputy Program Manager. “It is an early demonstrator, and we are confident we can take this same technology and make it more effective to protect our personnel around the world.”

“We couldn’t have come this far without the perseverance and professionalism of the entire THOR team,” added Ken Miller, AFRL’s High Power Electromagnetics Division Chief. “Our scientists, Airmen and contractors worked early mornings and late nights to make this swarm demo a great success. AFRL is committed to developing such advanced technologies to defend our service members on the front lines.”
