USAF tests anti-drone
swarm energy weapon

The US Air Force (USAF) has successfully defeated a so-called “drone swarm” in recent tests using a microwave energy weapon.

Tactical High-power Operational Responder, or THOR, uses high-power
microwaves to defeat small UAVs flying at low altitude
The Air Force Research Laboratory (AFRL) on 16 May said a system known
as the Tactical High-power Operational Responder (THOR) was able to down
multiple small aerial targets in a simulated attack.
“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,” says Adrian Lucero, programme manager with the AFRL’s directed energy
directorate.
The demonstration occurred on 5 April, the AFRL says, but was only
recently reported.
With the global proliferation of dedicated military unmanned aerial
vehicles (UAVs) and small commercial quadcopter drones, military planners in
Washington have been seeking options to defeat them on the battlefield.
While lone UAVs can provide powerful battlefield effects, such as
kinetic strikes, reconnaissance or artillery spotting, generals at the Pentagon
are particularly concerned about large numbers of cheap, small craft operating
in unison against ground troops or stationary air bases.
The US Army has already demonstrated that dozens of commercial
quadcopters can be synchronised into drone swarms via artificial intelligence algorithms and controlled by a single
soldier.
While traditional air defences and some counter-UAV systems use guided munitions to destroy aerial targets, the small size of
quadcopters and numerous potential targets present a challenge for projectile
weapons.
Systems like THOR use electronic warfare measures to jam, disrupt or
even destroy the many UAVs making up a swarm. In the case of the recent tests,
AFRL researchers “flew numerous drones at the THOR system to simulate a
real-world swarm attack”, according to Lucero.
While the USAF declined to disclose how many or what type of UAVs were
employed in the test, citing security concerns, the service says the microwave
weapon system was effective at defeating the swarm.
“THOR was extremely efficient, with a near continuous firing of the
system during the swarm engagement,” says USAF Captain Tylar Hanson, THOR
deputy programme 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,” he adds.
The presence of cheap, easy to obtain commercial drones and military
UAVs has already become a defining trait of the 15-month-old Russia-Ukraine
war; Europe’s largest conflict in decades.
The technology has also appeared in conflicts including the Syrian civil war and the Second Nagorno-Karabakh war between Armenia and
Azerbaijan.
The former commander of US Special Operations Command, retired General
Richard Clarke, in 2022 described the proliferation of UAVs and commercial drones
as having the ability to disrupt the global military order.
