ExDECS is a mobile, solid-state HPM system derived from the company’s Leonidas Expeditionary platform. It was developed under a contract awarded by the U.S. Navy’s Office of Naval Research (ONR).
In September 2024, ONR awarded Epirus a follow-on contract to further support testing and evaluation of the system under the Preliminary Evaluation of Ground-based Anti-Swarm UAS System (PEGASUS) programme. Following the signing of the Department of Defense Form DD250, confirming Factory Acceptance Testing, the prototype was shipped to Dahlgren, where it completed Government Acceptance Testing.
The system will now be used to support the Marine Corps’ experimentation objectives in the Low Altitude Air Defense (LAAD) mission. It aims to enhance Ground Based Air Defense (GBAD) capabilities by assessing the impact of HPM technology.
Leonidas Expeditionary, introduced in 2024, is the most recent addition to Epirus’ portfolio of scalable HPM systems for counter-electronics applications. The system is designed for integration with light tactical vehicles, companion trailers, and other mobile platforms to strengthen expeditionary short-range air defence.
“Drone warfare is changing the fight — fast. Systems like ExDECS give Marines a decisive advantage by neutralising multiple electronic threats at once with a single system — what we call a one-to-many capability,” said Andy Lowery, CEO of Epirus.
“This delivery is a critical step toward fielding non-kinetic counter-swarm solutions that enhance the mobility, survivability, and lethality of our Marine forces,” Lowery added.
