Counter-UAV: Epirus engages Colombia, also works with GDLS and Kodiak AI for Leonidas AGV.

Counter-UAV: Epirus engages Colombia, also works with GDLS and Kodiak AI for Leonidas AGV. 11 April, 2026 Three major defense companies, Epirus, General Dynamics Land Systems (GDLS), and Kodiak AI, have teamed up to develop a new autonomous vehicle for counter-uncrewed aerial vehicles (Counter-UAV) missions: the Leonidas Autonomous Ground Vehicle (AGV). The vehicle was unveiled at the recent AUSA Global Force Symposium & Exhibition expo in Alabama. Zona Militar spoke with Andrew Wargofchik, spokesperson for Epirus, about the Leonidas AGV and the company's projects in Latin America. Regarding Colombia, Wargofchik explained that Epirus is engaging the Colombian Ministry of Defense regarding the "potential of integrating" the company's high-power microwave (HPM) platform "into their counter-UAS shield." The company is confident that other Latin American militaries and security services will similarly be interested in Epirus's systems to combat drones operated by criminal gangs and narco-insurgents. The so-called narco-drones can transport explosives, drugs, or be utilized for surveillance missions. "The Leonidas high-power microwave platform is capable of supporting the Latin American counter-UAS initiatives" aimed at eliminating these threats. Wargofchik explained that the company's technology is "scalable and modular, and works by injecting high levels of microwave energy into a precise volume of space, coupling directly into the electronics of incoming threats. Latin American militaries are very interested in counter-UAV technologies. Case in point, the Colombian Ministry of Defense is seeking to develop a counter-UAV "national shield," while the Ecuadorian air force recently completed a training course on counter-UAV missions. As for the Leonidas AGV, the platform combines technologies from the three companies: GDLS provides the commercial-grade truck platform, Kodiak AI provides the autonomous driving system, and the payload is Epirus' Leonidas high-power microwave system, designed to counter UAV threats. A press release issued by the three companies describes the AGV as a "mobile counter-UAS capability that can be operated without human intervention or teleoperated to extend the counter-UAS line of defense across fixed-site and expeditionary mission sets." The Leonidas AGV can defeat single, swarm, or fiber-controlled drone attacks and is ideal for protecting a variety of locations, including military installations and forward operating bases. According to Epirus, integration of the systems and platforms of the three companies "took less than four months." As for the future of the Leonidas AGV, Wargofchik confirmed to Zona Militar that the three companies are "planning Leonidas AGV testing events in the coming months to further mature the system and demonstrate its counter-UAS and shoot-on-the-move capabilities," without providing specific details. The spokesperson did confirm that Epirus will be present at the upcoming Sea Air Space expo at the National Harbor in Maryland (near Washington, DC) to showcase its systems to the US Navy. Zona Militar also asked about the US military's response to the Leonidas AGV. To summarize, the response was "overwhelmingly positive" due to Leonidas AGV's mobility, autonomy, and commercial development timeline, which "directly answers the modernization calls of the Department of War and US Army." Wargofchik explained that the "Leonidas AGV is well-suited for a range of multi-service missions, including JIATF-401 homeland defense applications" as well as the defense of US Air Force assets and military installations. The company has continued to test and showcase Leonidas's capabilities through a variety of demonstrations and tests, including a December 2025 live-fire demonstration at an undisclosed US government testing site. The target was a fiber-optic guided UAV, which has become quite popular in the ongoing war between Russia and Ukraine. Also, last year, on 26 August, 2025, the company carried out another demonstration, this time against a swarm of UAVs. According to the company, Leonidas was tested against 61 drones across five operationally relevant flight scenarios. The result was very successful, as Leonidas managed to disable 61 of 61 drones and defeat a 49-drone swarm.

General dynamics-led team unveils self-driving truck with microwave counter-drone tech.

General dynamics-led team unveils self-driving truck with microwave counter-drone tech. The Leonidas Autonomous Ground Vehicle consists of a commercial Ford F600 model truck tricked out with Kodiak's autonomous driving software and Eprius' high-power microwave (HPM) c-UAS platform. By Carley Welch on March 24, 2026 9:00 am GLOBAL FORCE 2026 - General Dynamics Land Systems, Epirus and Kodiak AI unveiled today a new mobile, autonomous vehicle for counter unmanned aerial system (UAS) missions, dubbed the Leonidas Autonomous Ground Vehicle (AGV). The prototype AGV shown here in Huntsville, Ala., consists of a commercial Ford F600 model truck tricked out with Kodiak's autonomous driving software and Epirus' Leonidas high-power microwave (HPM) c-UAS platform. GDLS serves as the lead systems integrator for the product, responsible for ensuring all the platforms work together. Andrew Brown, Epirus' US Army growth lead, told Breaking Defense in an interview that the three companies teamed up to make the AGV after the Army's former Rapid Capabilities Critical Technologies Office gave a "definitive direction" that it wanted a prototype of a mobile HMP solution. Brown said the companies hope to embed the product with the Army-led Joint Interagency Task Force (JIATF) 401, responsible for the Defense Department's counter-drone efforts regarding homeland defense, as well as the broader Army. "We're tight and close with the Army and the other services, but also JIATF 401," Brown said. "So we see the AGV as part of that solution for defense and homeland security, both for military installations, but also can be used for airports, air bases, railheads, national infrastructure [and] critical infrastructure." An appeal of the product, Brown said, is that it can take down drones without causing much surrounding damage and it is cheaper than exquisite interceptor systems. The option for unmanned navigation means soldiers can stay out of harm's way, he said. Ray Moldovan, business development manager at GDLS, acknowledged that the AGV is in the prototyping phase at this point and has not yet been tested to take down drones while driving autonomously, but he said the team is hoping to conduct testing with JIATF 401 sometime this year, depending on the Army's interest. "As a team here, we're looking for that definitive signal from the Army customer to go. I think it's akin to holding back race horses here, we're ready to answer the call of the Army when it comes," he said. Brown said that the first generation of the Epirus' HPM system was used in the Indo-Pacific theater last year as part of the Army's Balikatan exercise. The second generation recently completed testing in February with the Army, and the service owns two of those systems, he said. In regards to Kodiak's autonomous driving solution, Chet Gryczan, the managing director of Kodiak Defense, said it allows the AGV to drive on terrain ranging from highways to off-road environments without endangering a driver. Currently, Kodiak is on contract with the Marines to integrate its autonomous driving system into Joint Light Tactical Vehicles for the service's Remotely Operated Ground Unit for Expeditionary Fires platform. The company also provides its autonomous system to the commercial market, Gryczan added. "The partnership here is really that this vehicle is delivering capability to the warfighter that's, frankly, faster. We're doing it faster and smarter and and really at a scale that we can kind of address the Army's needs and what they're asking for right now, where we see perhaps there's a gap," he said. "The fact that we're leveraging a commercial platform and a commercial driver, and bringing Epirus' Leonidas to this as well is a match made in heaven, so to speak." In addition to making sure every aspect of the AGV fits together, GDLS is also in charge of modifying the commercial vehicles so they can receive the various sensors to connect with the autonomy, Moldovan told Breaking Defense. Though the current prototype uses a F600 truck, he said the system can work with any commercial truck.
