The key to 'Rearm Europe' is automated, military (intra-)logistics

“Rearm Europe”: How the EU is building on digitalization and automation in defense

The European rearmament initiative “Rearm Europe” faces a fundamental challenge: How can Europe build up its defense capabilities with the necessary speed and efficiency to meet the geopolitical threats of the 21st century? The answer lies not only in procuring new weapons systems or increasing defense budgets, but rather in the revolutionary transformation of military logistics through advanced automation and artificial intelligence.

The new dimension of the military logistics challenge

The “Rearm Europe” initiative, or “Readiness 2030” as it was renamed after diplomatic discussions, represents Europe’s response to the changed security situation since Russia’s war of aggression against Ukraine. With a planned volume of over €800 billion by 2030, this is the largest European rearmament initiative since the Second World War. However, the sheer size of the financial resources alone does not guarantee success.

European defense logistics faces complex structural problems. National fragmentation, a lack of interoperability between systems, and an inadequate industrial base have made Europe strategically dependent on non-European partners. At the same time, the conflict in Ukraine clearly demonstrates that modern warfare is no longer won solely through traditional "heavy metal" approaches—tanks, artillery, and conventional systems—but rather through the intelligent integration and networking of all available resources.

Automation as the core of the strategic realignment

The crucial component for the success of “Rearm Europe” lies in the comprehensive automation of military intralogistics. This encompasses not only physical transport operations, but the entire supply chain from procurement and storage to distribution to end users. Automated systems can help overcome the chronic weaknesses of European defense logistics.

Modern military operations generate enormous logistical demands. A single main battle tank requires between 400 and 600 liters of fuel daily, in addition to ammunition, spare parts, and provisions for the crew. Larger operations involving several thousand vehicles and tens of thousands of soldiers create logistical challenges that are virtually impossible to manage without automated support. This highlights the transformative potential of automation: it can not only increase efficiency but also drastically reduce reaction times and minimize error rates.

The automation of intralogistics encompasses various technological levels. At the operational level, driverless transport systems and autonomous vehicles enable the transport of supplies even in hazardous areas without endangering human personnel. Intelligent warehouse systems with automated storage and retrieval systems and robot-assisted order picking can reduce processing times by up to 70 percent while simultaneously increasing accuracy.

Artificial intelligence as an enabler of intelligent logistics networks

The second crucial element is the use of artificial intelligence to optimize the entire supply chain. AI systems can process massive amounts of data in real time and derive precise forecasts for material requirements. This enables predictive logistics, where supplies are already en route before they are even requested.

Predictive maintenance of military equipment is particularly relevant. Modern weapon systems and vehicles are equipped with a multitude of sensors that continuously collect operational data. AI algorithms can identify patterns in this data and predict failures before they occur. This makes it possible to deploy spare parts and maintenance teams precisely when and where they are needed. Studies show that predictive maintenance can increase equipment availability by 10 to 20 percent while simultaneously reducing maintenance costs by 5 to 10 percent.

The integration of AI into military logistics goes far beyond simple optimization algorithms. Modern systems can plan complex multimodal transport chains, calculate alternative routes in case of disruptions, and even simulate the impact of enemy actions on supply security. This creates a resilient logistics architecture that remains functional even under challenging conditions.

The German and European innovation landscape

In recent years, Germany has developed into a major center for military automation technologies. Companies like Rheinmetall are investing heavily in AI-based systems and autonomous platforms. Rheinmetall's PATH A-Kit, an AI-powered navigation system that can be integrated into virtually any vehicle, demonstrates the potential of platform-agnostic solutions. Rheinmetall has already achieved initial success with autonomous convoy systems in international competitions such as the European Land Robot Trial 2024.

At the same time, innovative startups like ARX Robotics are emerging, pursuing software-defined defense approaches and modernizing existing military vehicle fleets through the retrofitting of AI systems. These modular solutions offer the advantage of being cost-effectively integrated into existing systems without requiring complete new procurements.

The European research landscape is working intensively on the further development of military automation technologies. Projects such as RoX, funded by the German Federal Ministry for Economic Affairs and Climate Action, aim to develop digital ecosystems for AI-based robotics. These initiatives combine basic research with practical application development and create the technological basis for the next generation of military logistics systems.

Interoperability as a cornerstone of European defense logistics

A key problem in European defense logistics is the lack of interoperability between the various national systems. Each country has developed its own standards and procedures over decades, leading to significant inefficiencies in multinational operations. The “Rearm Europe” initiative offers the opportunity to overcome this fragmentation through unified, automated standards.

NATO has already taken important steps in this direction. The Logistic Functional Area Services (LOGFAS) system and similar initiatives aim to establish common data standards and interfaces. Automated systems can help enforce these standards, as they are inherently based on standardized protocols.

Of particular relevance is the concept of “military mobility,” which aims to simplify and accelerate cross-border troop movements. Automated logistics systems can not only optimize physical transport processes but also reduce bureaucratic hurdles through automated documentation and approval procedures.

The global economy is currently undergoing a fundamental transformation, a watershed moment that is shaking the foundations of global logistics. The era of hyper-globalization, characterized by the relentless pursuit of maximum efficiency and the "just-in-time" principle, is giving way to a new reality. This new reality is marked by profound structural breaks, geopolitical power shifts, and increasing fragmentation of economic policy. The once taken-for-granted predictability of international markets and supply chains is dissolving and being replaced by a period of growing uncertainty.

Challenges in implementation

The introduction of automated logistics systems in military contexts presents specific challenges. Security aspects are paramount: Automated systems must be protected against cyberattacks and be able to continue functioning even in the event of partial system failures. This requires redundant systems and robust encryption methods.

Another critical aspect is staff training. The introduction of automated systems fundamentally changes workflows and requires new skills from operators. This includes not only the technical operation of the systems, but also an understanding of the underlying processes and the ability to troubleshoot malfunctions.

The costs of developing and implementing automated logistics systems are substantial. Estimates suggest that fully automating European defense logistics would require investments in the hundreds of billions. However, these investments must be considered in the context of long-term savings: automated systems can reduce operating costs by 20 to 30 percent while significantly increasing efficiency.

Key technological components

Modern military intralogistics relies on a multitude of interconnected technologies. Autonomous vehicles form the backbone of the physical transport chain. These range from small drones for supplying isolated units to heavy unmanned trucks for transporting bulk goods. The development of these systems has made significant progress in recent years: modern autonomous military vehicles can already navigate complex terrain while avoiding enemy activity.

Intelligent warehouse systems represent another key component. These systems utilize a combination of robotics, AI, and advanced sensors to automate the entire warehouse process. Modern systems can not only automatically perform storage and retrieval operations but also monitor the condition of stored goods and raise alarms when necessary.

All system components are integrated via central control platforms based on AI algorithms. These systems can solve complex optimization problems in real time, such as optimal route planning for hundreds of vehicles or the allocation of resources across different priorities. They consider not only static parameters like distances and capacities, but also dynamic factors such as traffic conditions, weather, and threat scenarios.

Predictive maintenance as an efficiency factor

A particularly important aspect of automated military logistics is the predictive maintenance of equipment and systems. Military vehicles and weapon systems often operate under extreme conditions

This can lead to increased wear and unpredictable failures. Traditional maintenance concepts are either based on fixed intervals or only react after damage has occurred – both approaches are inefficient and costly.

Modern predictive maintenance systems use a combination of IoT sensors, machine learning, and advanced data analytics to continuously monitor the condition of equipment and predict failures. These systems can analyze vibrations, temperatures, oil pressure, and other parameters in real time, identifying patterns that indicate impending problems.

The advantages of this technology are considerable: studies show that predictive maintenance can increase the availability of military equipment by up to 25 percent, while simultaneously reducing maintenance costs by 10 to 15 percent. For European defense, which often has to operate with limited resources, this can mean the difference between successful and failed missions.

Cybersecurity and resilience

The increasing networking and automation of military logistics creates new attack vectors for cyberattacks. Adversary forces could attempt to hack, disrupt, or even take over automated systems. This necessitates a comprehensive cybersecurity concept that includes both preventive and reactive measures.

Modern military automation systems must therefore be developed according to the principle of "security by design." This means that security aspects are integrated into the system architecture from the outset, rather than being added later. This includes encrypted communication, secure authentication, regular security updates, and the ability to isolate compromised system components.

At the same time, automated logistics systems must remain functional even in the event of partial failures. This requires redundant systems, decentralized decision-making structures, and the ability to automatically reconfigure themselves in case of malfunctions. Only in this way can it be ensured that supplies are maintained even under adverse circumstances.

Integration of civilian and military logistics structures

An innovative approach to strengthening European defense logistics lies in the better integration of civilian and military logistics capabilities. Civilian logistics companies possess advanced automated systems and extensive infrastructure that could be used for military purposes in times of crisis.

This civil-military fusion, modeled on the Chinese example, could bring significant efficiency gains to Europe. Civilian logistics companies have already gained extensive experience with automated warehouse systems, AI-supported route optimization, and predictive analytics. This expertise could also benefit military logistics through suitable cooperation models.

At the same time, military technologies could also find civilian applications. Robust automated systems developed for military purposes could be used in civilian logistics centers, while civilian innovations could find military applications. These synergies could reduce development costs and increase the speed of innovation.

The Security and Defence Hub offers expert advice and up-to-date information to effectively support companies and organizations in strengthening their role in European security and defence policy. Working closely with the SME Connect Defence Working Group, it particularly promotes small and medium-sized enterprises (SMEs) that wish to further develop their innovative capacity and competitiveness in the defence sector. As a central point of contact, the Hub thus creates a crucial bridge between SMEs and European defence strategy.

European Industrial and Technological Strategy

The success of “Rearm Europe” depends crucially on whether Europe can develop an independent industrial and technological base for automated logistics systems. Dependence on non-European technology providers would undermine strategic autonomy and make Europe vulnerable in critical situations.

The European Defence Agency (EDA) and national research institutions are already working on developing European standards and technologies for military automation. At the same time, European defense companies are investing heavily in AI research and autonomous systems. Rheinmetall, for example, has announced plans to invest several billion euros in the development of digital defense technologies in the coming years.

Of particular importance is the development of European champions in critical technology sectors. Companies like Rheinmetall, Thales, and Leonardo must become global leaders in military automation solutions to guarantee Europe's technological sovereignty. This requires not only financial investment but also the creation of suitable regulatory frameworks and the promotion of research and development.

Training and staff development

The successful implementation of automated logistics systems requires a fundamental reorientation of military training. Soldiers must not only learn to operate highly complex technical systems, but also understand the underlying principles and processes.

This affects various qualification levels: At the operational level, soldiers must learn to operate and monitor automated systems and intervene in case of malfunctions. At the tactical level, officers must understand how to optimally integrate automated logistics capabilities into their operational planning. At the strategic level, leaders must understand the capabilities and limitations of automated systems in order to make informed decisions about investments and deployment.

Training must be practice-oriented and include realistic scenarios. Simulators and virtual training environments can help to practice complex situations without risking expensive equipment. At the same time, continuous professional development programs must ensure that staff can keep pace with rapid technological advancements.

International cooperation and standardization

The automation of military logistics can only be successfully implemented through close international cooperation. Most modern military operations are multinational undertakings that require seamless collaboration between different armed forces.

NATO and the EU have already taken important steps toward harmonizing logistics standards. The NATO Logistics Stock Exchange (LSE) and similar initiatives aim to establish common procurement procedures and warehousing standards. Automated systems can help enforce and monitor these standards.

The development of common interfaces and protocols for automated systems is particularly important. Only when systems from different nations can work together seamlessly can the full efficiency gains of automation be realized. This requires not only technical standardization, but also legal and organizational harmonization.

Economic impacts and efficiency gains

The automation of military logistics promises significant economic advantages. Current studies suggest that the complete automation of European defense logistics could reduce operating costs by 20 to 30 percent, while simultaneously increasing efficiency by 40 to 50 percent.

These efficiency gains result from various factors: Automated systems work more precisely and faster than human operators, they require no breaks and can be used around the clock. At the same time, they reduce human error, which can be particularly costly in military logistics.

The resources saved can then be used for other critical areas, such as the procurement of modern weapons systems or the improvement of soldiers' equipment. This creates a positive cycle in which efficiency gains in logistics enable additional investments in defense capabilities.

Future prospects and development trends

The development of automated military logistics systems is still in its early stages. Further technological breakthroughs are expected in the coming years, offering the potential for even greater efficiency gains.

Developments in the field of swarm-intelligent systems, where hundreds or thousands of autonomous units work together in a coordinated manner, are particularly promising. Such systems could solve complex logistics tasks completely autonomously, without requiring human intervention.

The integration of quantum computing and advanced AI also promises further improvements. Quantum computers could solve complex optimization problems that are unsolvable with conventional computers, while advanced AI systems will enable even more precise predictions and decisions.

The trend is moving towards fully autonomous logistics ecosystems that are self-learning and self-optimizing. These systems would not only react to pre-programmed scenarios, but would continuously learn from new situations and improve their performance.

Conclusion: Automation as an enabler of European defense capability

Automated military intralogistics is not merely a technical upgrade of existing systems, but the key to the successful implementation of the “Rearm Europe” initiative. Without a fundamental transformation of logistics processes through automation and artificial intelligence, Europe will not be able to achieve its defense objectives in a timely manner and with the necessary efficiency.

The challenges are considerable: technical complexity, high investment costs, cybersecurity risks, and the need for extensive personnel training. However, the advantages far outweigh the disadvantages: drastic increases in efficiency, reduced costs, improved responsiveness, and ultimately, a stronger defense capability for Europe.

Success will depend on whether Europe makes the necessary investments, develops the required technological capabilities, and implements the organizational changes. Time is of the essence: geopolitical tensions are rising, and Europe must act quickly to secure its strategic autonomy. Automated military logistics offers a path forward—it is up to political and military leaders to follow it.
