In today’s geopolitical landscape, the definition of sovereignty is becoming increasingly complex. For defense organizations, the challenge is no longer just about ownership or control; modern sovereignty increasingly requires an approach that balances operational control, national resilience, and crucial interoperability with allied forces. This shift reflects a broader evolution from traditional definitions of sovereignty toward a more modern understanding where multidimensionality delivers strategic advantage in space-based communications.
Beyond Ownership: The Three Pillars
Complete end-to-end ownership was the main focus of traditional sovereignty, but this approach is no longer practical. As Ali Grey Associate Partner at PA Consulting shared, “so few organizations or nations can afford to have [a system that is completely] designed, delivered, and operated in-country.”
Keith Blanchet, Vice President of International Government & Defense at ST Engineering iDirect, described a more practical framework built on three pillars. The first pillar is national resiliency which “goes well beyond just resiliency of the network but has to do with supply chain and many other dimensions.” The second is “replacing the idea of sovereign ownership with sovereign control.” The third pillar is interoperability. Global theaters of operation inherently involve alliances, making the ability to work with allies non-negotiable for effective defense.
Avoiding the Sovereignty Trap
Rather than pursuing fully sovereign and independent systems, nation-states should prioritize building depth and selective sovereign capabilities. As Grey noted “use what’s there and be clear about the things that you really need control over … and then use everything else at your disposal that’s being provided by all the organizations that are putting billions and billions into [commercial systems] but just don’t rely on it [commercial systems] at a time of war.”
Open Standards and Future-Proof Design
Open standards like 5G NTN and Digital Intermediate Frequency are becoming increasingly important force multipliers. If allied nations adopt common standards, their defense organizations can create a common technical framework while maintaining strategic independence. Instead of forcing nations into lockstep compliance, an open standards framework allows each nation to optimize innovations tailored to their unique security needs and operational requirements. With this strategy, nation-states retain flexibility to implement proprietary encryption, sovereign waveforms, and operational procedures specific to their unique threat landscapes. The standards create a common framework that allows interoperability among diverse systems that support national and alliance objectives.
Systems must also be designed with long-term technological evolution in mind. In many cases, the biggest weaknesses are not cryptographic, but human error and process vulnerabilities at the operational edge. To reduce these risks and ensure that individual operators cannot compromise system integrity, automation and zero trust architectures are essential. Additionally, systems must be future proof with the ability to adapt to emerging threats, including the eventual threats that might be posed by post-quantum computing.
The Path Ahead
The definition of sovereignty in this new era of military satellite communications is less about controlling every component. Instead, sovereignty today is about maintaining strategic decision-making authority, building resilience through diversity, and prioritizing flexibility to adapt. In an era of rapid technological change and shifting alliances, this multidimensional understanding of sovereignty offers a more practical and resilient approach to national defense.
