ARX Robotics is building software-defined ground platforms into an interoperable defense layer

ARX Robotics secured its first British Army contract through Task Force RAPSTONE and began UK manufacturing of autonomous ground vehicles. The order covers GEREON uncrewed ground vehicles configured with intelligence, surveillance and reconnaissance payloads, plus technical support for Recce-Strike experimentation.

UK Manufacturing Footprint

The British Army order sits inside a £45 million UK expansion plan targeting production of up to 1,800 robotic vehicles annually and at least 90 skilled jobs. ARX refined the first UK-manufactured GEREON vehicles through field exercises in Kenya and the Baltics with British Army operators.

ARX operates manufacturing capacity in the UK and continental Europe. The UK facility supports British Army contracts while European production supports GEREON vehicles, Mithra OS integration work and wider UGV supply.

Founding and Funding

Marc Wietfeld is CEO, Maximilian Wied is CFO and Stefan Roebel is COO of ARX Robotics, which they co-founded in 2022 after service as former German Army officers. The company raised €31 million in Series A funding in 2025 from HV Capital, Omnes Capital and the NATO Innovation Fund, with Project A, Discovery Ventures and Expansion Ventures participating.

GEREON uncrewed vehicles support reconnaissance, logistics resupply, route clearance, casualty evacuation and force protection. Mithra OS is ARX's operating system for autonomous ground platforms, built to integrate autonomy, sensors and software control across robotic vehicles and legacy military fleets.

Products and Partnerships

RENK and ARX formed a partnership covering Mithra OS integration with RENK mobility systems, joint product development, joint production sites and international distribution across the USA, UK, France, Italy, India and the Middle East. RENK brings customer relationships across 70+ armies and 40 navies.

Hector extends ARX's software-defined ground platform approach into a medium-class, optionally manned UGV built on Mithra OS. The platform uses a shared chassis across internal-combustion and electric configurations, 120 km/h top speed, up to 4 km control range, up to 500 kg load capacity, thermal night vision cameras and modular attachments.

Deployment and Validation

Exercise Haraka Storm in Kenya integrated an ARX GEREON UGV with Helsing's HX-2 loitering munition in a ground-to-air Recce-Strike sequence with British Armed Forces. British troops from 2 SCOTS used GEREON to locate an armoured vehicle, transmit targeting data to battlegroup headquarters and enable HX-2 to strike the designated target.

The Task Force RAPSTONE contract moves UK-manufactured GEREON configurations into British Army Recce-Strike experimentation. ARX also discloses deployments with several European armed forces and active use in Ukraine.

Maturity

ARX has public record disclosures covering founder roles, Series A capitalization, UK manufacturing expansion, RENK and Helsing partnerships, British Army procurement and a Recce-Strike field demonstration in Kenya. Public material does not show delivered unit counts by individual customer, total fleet sizes with British or European forces, precise Task Force RAPSTONE contract value, production cadence by facility, or measured field performance from active deployments in Ukraine.
