U.S. Army Tests Mobile Microwave Drone Killer System for Ammunition-Free Air Defense.

A U.S. mobile high-power microwave system has demonstrated the ability to disable drones without using missiles, offering ground forces a scalable way to counter growing UAV threats. This matters because it provides a reusable, low-cost defense option that can protect maneuver units against mass drone attacks without depleting ammunition.

The system combines precision radar tracking with a directed-energy microwave weapon that disrupts drone electronics in flight. This approach highlights a broader shift toward non-kinetic air defense solutions designed to improve survivability and sustain operations in drone-saturated battlefields.

ThinKom Solutions' truck-mounted High Power Microwave counter-UAS system, integrated with Echodyne's EchoShield radar, demonstrated a mobile non-kinetic capability designed to detect, track, and disable hostile drones by disrupting their onboard electronics during a U.S. Army Cross Domain Fires experiment (Picture source: ThinKom).

The March 2026 experiment, conducted across Fort Sill, White Sands Missile Range, and Yuma Proving Ground, assessed emerging capabilities for cross-domain fires, sensing, targeting, and effects delivery. For the Army, the ThinKom-Echodyne integration matters because it addresses one of the most urgent battlefield gaps: defeating low-cost unmanned aircraft at speed, on the move, and at sustainable cost.

ThinKom’s system is built around the company’s VICTS, or Variable Inclination Continuous Transverse Stub, antenna architecture, a steerable mechanical phased-array technology originally developed for high-performance satellite communications. Unlike conventional electronically scanned arrays, VICTS uses mechanical beam steering while preserving phased-array-like agility, allowing the antenna to handle very high input power with lower thermal and prime-power penalties.

This is central to the weapon’s military value. ThinKom says its VICTS arrays have demonstrated gigawatt-level power handling, a key threshold for high-power microwave applications in which the objective is not to jam a radio link but to deliver sufficient electromagnetic energy to damage or disrupt a drone's internal electronics.

A high-power microwave effector attacks the vulnerability common to nearly every small unmanned aircraft: exposed electronics. Energy can couple through antennas, wiring, sensors, apertures, or structural seams, inducing currents and voltage spikes that can affect the flight controller, GPS receiver, datalink, electronic speed controllers, power regulation circuits, or payload electronics.

This makes HPM tactically different from radio-frequency jamming. Jamming can break the command link or interfere with navigation, but many modern drones can continue on pre-programmed routes, use inertial navigation, or execute autonomous terminal attack profiles. A successful microwave engagement can create a hard-kill effect by rendering the platform unable to fly, navigate, communicate, or complete its mission.

The armament package displayed at the Army experiment appears to place the microwave antenna and associated power electronics on a light truck or pickup-class platform, emphasizing mobility rather than fixed-site base defense. That configuration is operationally significant because it could support convoy protection, artillery unit defense, forward logistics security, and maneuver force protection where static counter-drone systems cannot cover moving formations.

The sensor side of the system is equally important. EchoShield is a software-defined, pulse-Doppler, cognitive 4D radar operating in the Ku-band between 15.7 and 16.6 GHz, with the equivalent of more than 500 transmit/receive modules and the ability to track around 1,000 objects of interest.

Public specifications list EchoShield with a 130-degree azimuth by 90-degree elevation field of regard, 0.5-degree tracking accuracy in azimuth and elevation, and typical counter-UAS tracking ranges from 2.7 to 4.8 km for Group 1 drones, 4.8 to 6.4 km for Group 2, and 6.4 to 11.4 km for Group 3 targets.

In the ThinKom application, EchoShield provides the track quality required to aim a narrow microwave beam at a small, fast, low-radar-cross-section target. Echodyne states that its radar can deliver high-fidelity tracking data at a 10 Hz rate, while its AI/ML models classify objects such as fixed-wing drones and multirotors, reducing false alarms and helping the effector prioritize real threats.

The reference to full 360-degree and on-the-move capability should be understood as a system-level integration advantage. A single EchoShield radar has a defined sector of regard, but multiple radars or a suitable platform configuration can provide hemispheric coverage, enabling a moving vehicle to maintain awareness while the HPM effector slews toward the most dangerous track.

This capability fits directly into the layered counter-UAS model now emerging across the U.S. Army, where no single weapon is sufficient against the drone threat. Kinetic systems such as remote weapon stations, 30 mm airburst ammunition, missiles, and guns remain necessary, but they face magazine-depth and cost-exchange problems against swarms of inexpensive drones.

High-energy lasers offer precision and low cost per shot but require dwell time and are affected by obscurants, weather, and target surface characteristics. HPM can complement lasers by producing broader electronic effects against multiple targets or closely spaced drones, especially when rapid neutralization matters more than pinpoint structural destruction.

The tactical attraction is a deep-magazine defense. As long as the vehicle can generate electrical power and manage heat, the HPM system is not limited by missile inventory or cannon ammunition. That makes it relevant for prolonged defense of command posts, ammunition supply points, air-defense batteries, bridges, and logistics hubs exposed to repeated drone attacks.

The system also has a strong role in convoy and maneuver protection. A truck-mounted HPM effector cued by on-the-move radar could defend moving columns against reconnaissance drones, loitering munitions, and weaponized quadcopters before they provide targeting data or reach release distance. This would help close the gap between short-range air defense and electronic warfare protection at the tactical edge.

There are limitations. Effective microwave engagement depends on range, line of sight, beam control, target orientation, electronic hardness, safety procedures, and electromagnetic deconfliction with friendly radios, sensors, and vehicles. Commanders will also need clear rules for using HPM near civilian infrastructure or friendly unmanned systems.

ThinKom has not disclosed range, power output, pulse structure, recharge time, magazine endurance, or the number of simultaneous targets its mobile HPM system can defeat. Those parameters will determine whether the technology becomes a niche-based defense asset or a practical maneuver system for brigade combat teams and air-defense formations.

The Cross Domain Fires experiment is, therefore, less a procurement milestone than a warfighting signal. The Army is testing how radar, command-and-control automation, kinetic weapons, and non-kinetic effectors can compress the sensor-to-shooter chain against drone threats that now shape every battlefield from Ukraine to the Middle East.

For Army planners, the most important feature may not be the microwave weapon alone but the integration pathway. EchoShield’s data can support remote weapon stations, medium-caliber cannon, missiles, one-way attack drones, lasers, and HPM systems, creating the kind of modular architecture required for modern layered air defense.

If ThinKom can mature the system into a rugged, power-efficient, soldier-operable package, it could give U.S. forces a mobile electronic hard-kill layer against drones at a time when traditional air-defense economics are under severe pressure. The battlefield implication is clear: counter-UAS defense is moving from isolated sensors and single-purpose jammers toward networked, mobile, multi-effector kill chains able to protect formations while they fight, move, and sustain operations.
