Unlike conventional directed-energy weapons, the Leonidas HPM system produces a broad electromagnetic interference field, capable of downing multiple drones simultaneously by disrupting their internal electronics. The system’s GEN II version offers extended range—up to two kilometers—and 30% more power than its predecessor, with upgrades including lithium battery storage for standalone operation and cooperative firing capabilities.

CEO Andy Lowery stated that Leonidas was developed to counter evolving drone threats in what he calls the “6th domain” of war: physical cyber. He emphasized the system's mobility, scalability, and survivability, describing it as a solution not only for combat zones like the Middle East but also for homeland security during high-risk events such as the 2026 World Cup.

U.S. Eyes Broader Deployment Across Services And Allies

Following prior deployments in the Middle East and Indo-Pacific, the Army’s Rapid Capabilities and Critical Technologies Office is considering Leonidas for widespread adoption. The system’s modular design allows upgrades through its core Line Replaceable Amplifier Modules (LRAMs), reducing maintenance costs and allowing quick adaptation to different mission needs.

Potential markets include air base defense, mobile platforms like the Stryker vehicle, and integration into U.S. missile defense infrastructure. The system’s success could also support foreign military sales under the AUKUS Pillar II initiative, with Australia already evaluating Leonidas for battlefield use.

Lowery warned that while the system delivers unmatched electronic power, its strong signal could also make it a target. The Army is developing “shoot-and-scoot” tactics to mitigate this vulnerability, allowing Leonidas to fire briefly and relocate before being struck.
