German Military Robotics Firm ARX Raises €31 Million to Transform European Defense with AI-Powered Autonomous Vehicles

ARX Robotics Secures €31 Million to Revolutionize European Military Autonomy

As Europe continues to recalibrate its defense posture, ARX Robotics announced a funding milestone that signals a watershed moment for the continent's military technology landscape. The German startup, founded by former Bundeswehr officers, has secured €31 million in Series A funding to accelerate the development and deployment of its autonomous military ground systems—technology that is already revolutionizing frontline operations in Ukraine and reshaping NATO's approach to ground warfare.

The investment round, led by HV Capital with participation from Omnes Capital and continued backing from NATO Innovation Fund and Project A, brings the company's total funding to over €40 million in just three years of operation. But behind these impressive figures lies a more significant story about Europe's evolving military autonomy and the race to modernize land forces that have remained stubbornly resistant to technological disruption.

"The demand for modular, software-driven defense systems is growing rapidly—and we're building the company that will define this category in Europe," said Marc Wietfeld, CEO of ARX Robotics, whose military background informs the company's mission-focused approach. "At the core of ARX Robotics is a clear mission: to build the next generation of defense infrastructure through scalable robotics and software."

From Bundeswehr to Breakthrough: The Veterans Modernizing European Defense

In a region where defense innovation has historically been dominated by established industrial giants, ARX represents a new breed of defense technology company. Founded in 2022 by former German military officers Marc Wietfeld, Maximilian Wied, and Stefan Roebel, the startup has leveraged insider knowledge of battlefield requirements to rapidly develop solutions that address critical operational gaps.

Unlike traditional defense contractors that have gradually incorporated automation into existing platforms, ARX began with a digital-first approach. The company's founders experienced firsthand the limitations of conventional military vehicles during their service, particularly the vulnerability of manned systems in contested environments and the critical need for force multipliers in resource-constrained operations.

Their signature innovation—the Mithra OS operating system—enables conventional military vehicles to operate autonomously, creating a force-multiplier effect without requiring entirely new platforms. This retrofit strategy has profound implications for defense budgets and operational capabilities across NATO.

"What sets ARX apart is their fundamental understanding that software, not just hardware, will determine battlefield advantage in modern conflicts," explained a senior European defense analyst who requested anonymity due to ongoing work with multiple contractors. "Their insight was recognizing that most military ground vehicles remain essentially 'dumb' platforms despite advances in other domains like air and naval systems."

The Silent Revolution: AI-Driven Ground Systems Transform Combat Operations

Walking through ARX's production facility reveals a striking contrast to traditional defense manufacturing. Instead of massive assembly lines producing identical units, engineers work to install sophisticated sensor arrays and computing systems designed to transform conventional vehicles into interconnected autonomous platforms.

The company's product lineup addresses the full spectrum of unmanned ground capabilities:

The Gereon RCS unmanned ground vehicle serves as ARX's dedicated autonomous platform. Electrically powered and designed for payloads up to 500 kg, these one-tonne class vehicles can operate for up to 72 hours on a single charge. Their applications range from cargo transport and mine clearance to communications relaying, reconnaissance, and casualty evacuation—critical functions that traditionally expose personnel to unnecessary risk.

Even more transformative is the company's Mithra OS, launched in December 2024 as the world's first independent AI-powered operating system specifically designed for military vehicles. The system transforms conventional military vehicles into autonomous, interconnected units capable of adaptive navigation, autonomous reconnaissance, and remote operation. Perhaps most significantly, it enables manned-unmanned teaming—allowing human-operated vehicles to coordinate with autonomous systems in complex operations.

"Land operations have remained vastly under-automated despite accounting for 80% of military activities, 70% of material usage, and 40% of procurement," noted a military technology expert familiar with ARX's systems. "The ability to retrofit existing vehicles rather than replacing entire fleets offers an elegant solution to budget constraints while dramatically enhancing operational capabilities."

Real-World Validation: Ukraine Becomes Testing Ground for Next-Generation Warfare

The true measure of military technology lies not in demonstration environments but in actual combat conditions—and ARX has moved with remarkable speed to validate its systems in the most demanding proving ground available: the ongoing conflict in Ukraine.

In February 2025, ARX delivered 30 Gereon RCS UGVs to the Ukrainian Armed Forces, representing the largest Western-developed fleet of unmanned ground vehicles deployed to the conflict zone. These systems have demonstrated particular value in dangerous missions including logistics support to forward positions, casualty extraction, and reconnaissance in contested areas.

A defense ministry official from a NATO country, speaking on condition of anonymity due to the sensitive nature of military deployments, confirmed that ARX's rapid development cycle and battlefield-ready solutions have impressed military planners across the alliance. "What we're seeing in Ukraine is a validation not just of unmanned systems generally, but specifically of ARX's approach to autonomy and interoperability," the official said.

This real-world deployment has accelerated interest from other European forces. Currently, ARX is supplying UGVs to six European military forces, including Germany, Ukraine, and the UK. Testing is also underway by the armed forces of Austria, Switzerland, and Hungary, reflecting a growing recognition that autonomous ground systems represent a critical capability gap in European defense.

Strategic Expansion: Building European Defense Infrastructure

ARX's ambitions extend far beyond its current deployments. The company is pursuing a multi-pronged expansion strategy designed to establish it as the backbone of European defense autonomy.

In the UK, ARX is establishing headquarters in London and a production facility in southwest England, investing £45 million (€52.2 million) and creating 90 highly qualified jobs over the next 30 months. This facility will have a production capacity of up to 1,800 vehicles per year—a five-fold increase from current levels that reflects growing demand across NATO countries.

Perhaps more significantly, ARX has secured a strategic partnership with Daimler Truck, announced in March 2025, to integrate Mithra OS into Mercedes-Benz Special Trucks range, including the Unimog and Zetros models widely used by European militaries. This collaboration will embed ARX Core—the hardware component of the Mithra system—into vehicles to enable integration of sensors, cameras, and communication systems.

"The partnership with Daimler represents a fundamental shift in how military modernization can be approached," explained a military procurement specialist who has worked with several European defense ministries. "Rather than the traditional decade-long procurement cycles for all-new platforms, existing vehicles can be transformed into networked, autonomous systems in a matter of months."

The Geopolitical Context: Europe's Defense Renaissance

ARX's rapid growth coincides with a profound shift in European defense priorities driven by evolving geopolitical realities. The company's ascent reflects broader trends reshaping the continent's approach to military technology and strategic autonomy.

In March 2025, EU leaders endorsed the "ReArm Europe" plan, an ambitious initiative aimed at mobilizing up to €800 billion over four years to strengthen European defense capabilities. Simultaneously, the UK government committed to raising defense spending to 2.5% of GDP, signaling a continent-wide recognition that military preparedness requires substantial new investment.

These developments come against the backdrop of a global military UGV market projected to grow from $2.5 billion in 2023 to $7.8 billion by 2032, a compound annual growth rate of 13.3%. Europe's segment of this market was valued at €535.8 million in 2023 and is forecast to reach €775.8 million by 2030.

A former European defense official who now consults for industry noted that ARX represents the kind of innovative, agile company that European defense planners have long sought to cultivate. "For decades, Europe has wanted to develop its own defense-industrial ecosystem that can match American innovation while maintaining sovereign control over critical technologies," the consultant observed. "ARX exemplifies this new generation of European defense technology companies."

The Competitive Battlefield: David Among Goliaths

Despite its rapid growth, ARX faces formidable competition in the increasingly crowded military autonomy space. Established players include Estonia's Milrem Robotics, which has sold its THeMIS UGV to nine countries including seven NATO members, and industrial giants like Rheinmetall, whose Mission Master A-UGV family supports reconnaissance, fire support, evacuation, and CBRN roles.

American competitors include Textron Systems with its RIPSAW® M5-E featuring hybrid-electric drivetrains and field AI integration, while QinetiQ/Milrem's Titan UGV offers modular payload bays capable of handling 1,500-pound loads. Roboteam's TIGR and PROBOT platforms serve force-protection roles for multiple militaries.

What distinguishes ARX in this competitive landscape is its software-first approach and retrofit strategy. While competitors like Milrem's THeMIS enjoy wider deployment, they lack Mithra OS's independent AI layer that can be applied across different vehicle types. Similarly, Rheinmetall and Textron offer robust platforms but require full system procurement rather than enabling cost-efficient upgrades to existing fleets.

"The genius of ARX's approach is recognizing that military budgets can't support wholesale replacement of vehicle fleets, but incremental modernization through software and sensors offers tremendous operational gains at a fraction of the cost," explained a defense technology investor familiar with multiple companies in the sector.

Looking Forward: Challenges on the Horizon

As ARX deploys its newly secured capital, the company faces several critical challenges that will determine whether it can fulfill its ambitious vision of transforming European ground forces.

Scaling production from successful pilot deployments to industrial-scale manufacturing requires rapid facility expansion, robust supplier coordination, and stringent quality assurance under demanding military standards. The company must also ensure Mithra OS's reliability in contested environments, which entails rigorous cybersecurity certification, real-time fail-safe mechanisms, and interoperability with diverse command and control architectures.

On the regulatory front, ARX must navigate complex national procurement cycles, export controls, and EU defense procurement rules that can slow contract awards and deployments. Market consolidation or potential mergers and acquisitions—potentially subject to national security reviews—could also reshape the competitive landscape.

"The next 18 months will be critical for ARX," suggested a military technology analyst who tracks European defense startups. "They need to leverage this funding to establish themselves as the definitive European platform for autonomous ground systems before larger competitors can adjust their strategies or new entrants emerge."

A European Solution for European Defense

As defense budgets rise and autonomous systems increasingly define military capability, ARX Robotics stands at the forefront of a European defense renaissance. With its unique combination of military operational experience, software innovation, and strategic partnerships, the company exemplifies Europe's drive toward strategic autonomy in critical defense technologies.

The €31 million Series A funding represents more than just capital—it signals institutional confidence in ARX's vision of AI-driven military autonomy and recognition of the transformative potential of its technology. For European defense planners grappling with evolving threats and persistent resource constraints, ARX offers a path to modernization that leverages existing assets while dramatically enhancing operational capabilities.

In a landscape long dominated by legacy systems and established defense contractors, ARX's rapid rise suggests a new model for military innovation—one that values software integration, autonomous capability, and operational adaptability over traditional platform-centric approaches. As the company scales its production and expands its footprint across Europe, the true measure of its success will be whether it can transform not just individual vehicles, but the very nature of ground warfare itself.
