The United States has developed an electromagnetic microwave weapon named THOR to protect military airbases from drone swarms, detikNews reported. Developed by the Air Force Research Laboratory, the system uses high-power microwaves to disable multiple targets non-kinetically.
Electromagnetic Microwave System Mechanics
THOR, which stands for Tactical High-power Microwave Operational Responder, operates by emitting high-power microwaves to create a counter-electronic effect against incoming aerial threats. When the system identifies a target, the silent weapon fires in nanoseconds to neutralize threats instantly. The technology relies entirely on electrical power supplied by a standard wall plug rather than conventional ammunition.
Development Costs and Mobility Specifications
The total development cost for the electromagnetic defense technology reached approximately USD 18 million. In terms of transport, the entire THOR system fits securely inside a 20-foot transport container designed for movement via C-130 military cargo aircraft. Operators can assemble and prepare the unit for use within three hours, utilizing an interface built to require minimal user training.
Protecting military bases from drone attacks
The Air Force Research Laboratory created the system to address the rising deployment of drones as dangerous weapons against military installations. When measured against alternative defense measures like firearms, nets, and lasers, THOR provides a wider effect radius and faster target engagement times. The system’s defining characteristic is its capacity to engage multiple targets simultaneously during an attack.
