1. Strategic Context: From Protecting Networks to the Contest for Information Superiority
The digitalization of armed forces has transformed not only their operational technologies, but also the nature of military vulnerability. Modern command-and-control systems, intelligence and reconnaissance assets, air defence, uncrewed platforms, satellite navigation, and core logistics infrastructure all rely on digital networks, software, radio links, and continuous data exchange. Consequently, the ability to collect, process, secure, and transmit information in a timely manner has become a decisive factor in operational effectiveness.
This shift broadens the traditional concept of cybersecurity. Protecting military digital infrastructure is no longer confined to defending computers and static networks against intrusions. Digital systems are inextricably linked to the electromagnetic spectrum (EMS) through radio communications, radar, satellite links, and uncrewed assets. If the availability or integrity of these signals is degraded, system functionality can be severely impaired even without software-level compromise.
Modern defence architectures therefore integrate previously distinct operational fields: cyber operations, electronic warfare (EW / EloKa), signals intelligence (SIGINT), secure communications, and advanced data analytics. Their shared objective is to guarantee that friendly forces maintain access to reliable, real-time intelligence and preserve decision dominance even in heavily contested electronic environments.
The strategic relevance of this operational convergence has grown steadily across Europe over the past two decades. The full-scale war in Ukraine since February 2022 has underscored the decisive impact of synchronizing conventional combat power with cyber operations, electronic countermeasures, uncrewed systems, space-based assets, and information operations. For European defence planners, the lesson is clear: cyber and electromagnetic resilience are fundamental pillars of national and collective deterrence.
