Kaja Kallas, the EU’s High Representative for Foreign Affairs and Security Policy, has described military mobility as a critical insurance policy for European security. She stressed that the ability to move troops and equipment swiftly across borders strengthens deterrence and readiness. With tensions rising in Europe, she argued that the EU must act now to ensure its defence infrastructure keeps pace.
According to Kallas, the EU can no longer tolerate outdated procedures that delay deployments weeks. She pointed to examples where member-states still require up to 45 days’ notice for cross-border military movements, a timescale she called entirely out of step with today’s threats. Instead, she said, the aim must be to reduce these delays dramatically so forces can move in days or even hours.
The European Commission has backed this view and launched a new military mobility package to streamline logistics and upgrade infrastructure across the bloc. The package seeks to harmonise rules for moving military equipment, expand investment in dual-use transport corridors and create emergency mechanisms for rapid deployment. The goal is to build a harmonised military mobility area within the EU.
Europe’s key transport networks are now in the spotlight. Bridges, tunnels and rail lines that were built purely for civilian use may not be ready for the weight or speed demanded modern militaries. Kallas warned that if tanks or cargo planes cannot be deployed promptly, the continent’s ability to deter aggression is compromised. That means some civil infrastructure must be strengthened and re-imagined as part of defence.
For Portugal, this debate holds practical implications for Lisbon’s role as a regional hub. The country may face decisions on upgrading infrastructure, contributing to shared mobility corridors and aligning national rules with EU-wide standards. Improved military mobility could enhance Portugal’s strategic weight within EU and NATO frameworks.
Critically, the “insurance policy” metaphor Kallas used underlines the difference between wishing for peace and preparing for conflict. She emphasised that having capacity ready does not mean you will use it, but that readiness itself enhances deterrence. For the EU this means combining investment, regulation and political will to close gaps before a crisis hits.
As the EU advances its defence agenda, member states will need to coordinate more closely on logistics, procurement and standardisation. The military mobility initiative is not simply about hardware or highways. It is about trust, interoperability and the shared conviction that Europe can act both swiftly and collectively when challenged.
In summary, Kallas’s message is clear: Europe must treat military mobility not as an optional upgrade but as essential strategic infrastructure. As she put it, “you hope you never have to use it to full capacity, but having it ready ensures more credible defence.” The time to build that readiness is now.
