HPM (High-Power Microwave) System

Electromagnetic pulse weapon that generates a concentrated burst of microwave energy to destroy or disable drone electronics. Unlike RF jammers that disrupt communications, HPM physically damages onboard circuits — effective even against fully autonomous drones.

Overview

The High-Power Microwave (HPM) System produces a directed burst of electromagnetic energy that induces destructive voltages in unprotected electronic circuits. When the microwave pulse strikes a drone, it overloads and burns out processors, ESCs (electronic speed controllers), flight controllers, and other sensitive components — causing an immediate and unrecoverable loss of control.

The system emits energy in a cone-shaped pattern, creating a wide engagement volume that can simultaneously neutralize multiple targets. This area-effect capability makes HPM the most effective counter to drone swarms — a single pulse can disable dozens of drones within its coverage zone.

Unlike RF jammers, HPM does not rely on disrupting the control link. It physically destroys the drone's electronics, meaning it works equally well against autonomous drones flying pre-programmed waypoints, GPS-guided munitions, and drones operating on frequencies outside the jammer's coverage.

Key Advantage: The only defeat system effective against autonomous drone swarms — a single pulse can neutralize dozens of targets simultaneously.

Features

Swarm Neutralization

The wide-area cone pattern means a single microwave pulse can disable an entire drone formation. Where jammers must track and engage individual targets, HPM operates as an area-denial weapon — ideal for countering the swarm threat that overwhelms point-defense systems.

Autonomous Drone Defense

Because HPM destroys electronics rather than jamming communications, it is equally effective against fully autonomous drones with no RF link. Pre-programmed FPV strike drones, GPS-guided threats, and even inertially-guided drones within the coverage area are all vulnerable.

Minimal Per-Shot Cost

The system consumes only electrical energy — no ammunition, no expendable components. The cost per engagement is essentially the cost of the electricity consumed during the pulse, measured in cents rather than dollars.

Rapid Re-engagement

The system can fire repeated pulses at up to 1000 Hz, enabling sustained suppression of incoming waves of drones. Power and thermal management are the limiting factors, not ammunition supply.

Configurations & Pricing

ConfigurationRangeDescriptionPrice Range
Tactical100 – 500 mPortable/trailer mounted, rapid deploy$500,000 – $1,000,000
Installation500 m – 1 kmFixed site, higher power, extended coverage$1,000,000 – $2,000,000

Pricing includes the HPM source, beam-forming antenna, prime power system, and control unit. Requires dedicated power infrastructure. Installation and site preparation additional.

Limitations

Important: HPM pulses are non-selective — they affect ALL electronics in the coverage zone, including friendly equipment. Requires careful exclusion zone management. Effective range is limited (1 km max) compared to other defeat systems. Not suitable for urban deployment near civilian infrastructure.

The microwave pulse may affect friendly electronic equipment including communications, sensors, and vehicles within the engagement zone. Shielded or hardened drones (military-grade) may resist the pulse. Atmospheric conditions can attenuate the beam, though less severely than with laser weapons. The system is large and power-hungry, limiting deployment to fixed or vehicle-mounted configurations.
