Next chapter of neo-prime and prime partnership features Epirus’ Leonidas high-power microwave platform integrated with GDLS’s TRX robotic ground vehicle
Los Angeles, Calif—October 9, 2025—Epirus and General Dynamics Land Systems (GDLS) today announced the introduction of Leonidas Autonomous Robotic (Leonidas AR), a mobile counter-UAS capability featuring Epirus’ Leonidas high-power microwave (HPM) platform integrated with GDLS’s Tracked Robot 10-ton (TRX) unmanned ground vehicle.
Leonidas AR, powered by GDLS TRX, is a robotic ground vehicle equipped with Epirus’ HPM technology for mobile counter-UAS and short-range air defense. The integrated system is highly maneuverable for counter-UAS on the move and a low-cost, low-collateral electronic defeat mechanism ideal for the evolving drone threat environment.
“Epirus’ partnership with General Dynamics Land Systems is an industry-leading collaboration that continues to deliver real results. Together, we are bringing world-first capabilities to market that directly answer the call of the Army Transformation Initiative,” said Andy Lowery, Epirus CEO. “The marriage of neo-primes and primes is how the U.S. defense industrial base can best ensure victory as the battlefield continues to rapidly evolve.”
Leonidas is a modular, scalable, proven HPM solution that uses weaponized electromagnetic interference (WEMI) to disable electronic targets. The platform delivers a one-to-many engagement for swarm defense by which one Leonidas system can disable entire swarms of drones.
Leonidas is software defined, which empowers operators to define safe zones and notch out specific frequencies for low-collateral effects, as well as the ability to alter waveforms, modulate energy outputs and introduce new tactics of engagement for greater effectivity on target. Software also enables rapid innovation and feature updates without removing the system from the battlefield.
General Dynamics Land Systems’ TRX features AI-enhanced design, lightweight material, a hybrid-electric propulsion system and dynamic suspension for all-terrain mobility across combat environments. The vehicle features integrated radar for 360-degree sensing, on-board computing for maximum capability, a state-of-the-art battery system that allows for 300-plus miles of range and a maximum speed of 45 miles per hour. It can be autonomously or remotely operated in high-risk environments to reduce manning and protect air defenders. General Dynamics Land Systems is also developing a wheeled variant to support customer needs.
“By combining General Dynamics Land Systems’ decades of leadership in development and deployment of ground combat vehicles with Epirus’ premier non-kinetic counter-UAS effector, Leonidas AR achieves the level of next-generation technology that today’s battlefields demand. This new capability was born out of a partnership that leverages the best of American innovation to help our warfighters stay a step ahead,” added Jim Pasquarette, Vice President, U.S. Strategy & Business Development, General Dynamics Land Systems.
Leonidas AR is the second mobile counter-UAS system co-developed by Epirus and General Dynamics Land Systems after the companies entered into a teaming agreement in 2021. In 2022, the companies introduced Leonidas Stryker, which features the Leonidas HPM platform integrated with General Dynamics Land Systems’ Stryker, the U.S. Army’s largest and most reliable combat vehicle fleet.
The partnership between General Dynamics Land Systems and Epirus underscores how victory in The Sixth Domain will come from blending the scale and sustainment of traditional primes with the agility and disruptive innovation of neo-primes, creating hybrid ecosystems that can rapidly integrate, produce at scale and deliver mission-ready solutions across the modern battlespace.
A full-scale Leonidas AR prototype system will be on display at Booth 7609 in Hall D/E during the Association of the U.S. Army’s Annual Meeting and Exposition in Washington, D.C.
