Gereon UGV Mounts Vigil Launcher and Mark 1 Missile for Crewless Mobile Air Defense With UK Forces.

ARX Robotics, Babcock, and Frankenburg Technologies combined the GEREON UGV, Vigil launcher, and Mark 1 missile into a mobile counter-drone system at DVD 2026 in Millbrook, UK. The configuration is intended to move short-range air-defense effectors with UK ground forces and protect command posts, armored units and logistics nodes against drones and loitering munitions.

The GEREON-based configuration combines robotic mobility, Babcock’s modular Vigil launcher and Frankenburg’s Mark 1 interceptor in a distributed short-range air-defense role. It allows missile effectors to move with maneuver formations and creates an uncrewed firing node that can be positioned closer to the assets it is intended to protect.

GEREON provides the robotic carrier for the architecture. ARX Robotics describes it as a medium-sized autonomous and modular unmanned ground system designed to accept different mission payloads. The tracked platform reaches 15 km/h, has a driving range of 40 km, and can be controlled at distances of up to 4 km. Its payload capacity reaches 500 kg, while ARX lists manual and autonomous operating modes, thermal night-vision cameras, up to 72 hours of operating time, and a charging time of 2.5 hours. These characteristics allow the vehicle to move specialist payloads into exposed or dispersed positions while keeping personnel away from the launcher.

The air-defense component is based on Vigil, Babcock’s modular multidomain launcher. Vigil uses a munition-agnostic architecture intended to accommodate different effectors and to be adapted to land or maritime platforms. In its larger configuration, the launcher measures about 3 meters long, 1.6 meters wide and 1.5 meters high, with capacity for up to 24 effectors and a payload of 572 kg. It can also be integrated into 10, 20-, or 40-foot ISO containers, allowing the same launcher concept to support fixed installations, deployable land systems, or naval applications.

On GEREON, Vigil is configured with twelve Mark 1 missiles arranged in two groups of six around a central module. The smaller load reflects the dimensions and mobility requirements of the UGV rather than the capacity of a full-size Vigil installation. The result is a compact firing element carrying its own interceptor stock and able to reposition with maneuver units. Electro-optical equipment is also mounted around the central section, while the launcher can be connected to external detection and command assets as part of a wider air-defense network.

Frankenburg Technologies supplies the Mark 1, a lightweight guided interceptor developed for counter-UAS missions. The missile weighs less than 2 kg, measures 0.65 meter in length and has an engagement range below 2 km. It travels at high-subsonic speed, uses a solid-fuel rocket motor, and operates on a fire-and-forget basis with a proximity-fuzed warhead. Frankenburg states that the missile is intended to engage Class I to III UAS, including propeller-driven one-way attack drones and faster jet-powered targets. Its small dimensions allow several rounds to be carried on a relatively light platform, supporting repeated short-range engagements against drone threats.

The UK dimension extends beyond this configuration. ARX Robotics has begun manufacturing GEREON vehicles in Britain and secured an initial British Army order through Task Force RAPSTONE, with UK-built systems intended to support Recce-Strike experimentation. The company says it is investing £45 million in UK production capacity for up to 1,800 robotic vehicles annually. GEREON has also been used by British units during Project Convergence-Capstone 6 in the United States, where the UGV supported reconnaissance, counter-UAS, electronic warfare, logistics and casualty evacuation tasks while feeding data into brigade, divisional and corps-level networks.

Operationally, the GEREON-Vigil combination allows missile effectors to be distributed without assigning another crewed air-defense vehicle to every protected element. A launcher could be positioned near a command post, ammunition point, logistics hub, or armored formation while operators remain farther from the firing position. Several vehicles could be dispersed across a formation to create multiple launch points and reduce dependence on one air-defense node. When connected to external radar, electro-optical sensors, or a command-and-control network, the UGV can receive target tracks generated elsewhere and engage threats entering the Mark 1 envelope. The missile’s sub-2 km range still requires close positioning to the defended asset and places a premium on early detection and rapid target allocation.

For the United Kingdom and other NATO forces, the concept reflects a broader effort to distribute counter-UAS weapons across more numerous and less crew-dependent platforms. Attack drones and loitering munitions now threaten frontline units as well as headquarters, logistics routes and support areas, creating demand for defenses able to move with formations. GEREON with Vigil and Mark 1 does not replace medium- or long-range air-defense systems, but it can add a mobile point-defense layer built around dispersed sensors and effectors. In an operational configuration, the architecture could increase the number of available firing positions while limiting personnel exposure at individual launcher sites.
