The UK has spent nearly $40m on satellite services supplied by SpaceX, expanding its use of the company’s Starlink and military-focused Starshield networks while the Government pursues greater sovereign space capability.
Ministry of Defence information shows that Britain has acquired approximately 1,000 Starshield terminals and 500 Starlink terminals. Spending has reached about £13m on Starshield and £16.5m on Starlink, making satellite connectivity supplied through SpaceX an increasingly material element of defence communications.
The UK is also the first country outside the United States to publicly acknowledge using Starshield, the security-focused service developed for government and military customers.
Starlink was built primarily as a commercial satellite broadband network, while Starshield uses separate terminals and network gateways and is designed for military and national-security requirements, including enhanced encryption and priority access.
The Ministry of Defence began using Starshield in 2024 through existing Starlink equipment before purchasing dedicated terminals from 2025. The service operates across SpaceX’s wider satellite infrastructure, giving defence users access to the scale and coverage of its low-Earth-orbit network.
The spending exposes a strategic tension in UK space policy. The Government’s new national space strategy sets out plans for more resilient national satellite communications and places greater emphasis on domestic capability, security, procurement, and industrial growth.
Current operational requirements are nevertheless being met partly through infrastructure controlled by a US commercial provider. International procurement is routine across defence and communications, but the concentration of critical connectivity in a small number of private satellite platforms has increased the attention paid to resilience and sovereign access.
SpaceX has developed Starlink at a scale that most national programmes cannot reproduce quickly. Its constellation provides broad geographical coverage, a large installed base, and established ground infrastructure, making the service useful where terrestrial networks are unavailable, damaged, or operationally unsuitable.
Those characteristics have increased military demand as defence activity becomes more dependent on resilient data links, distributed sensors, remotely operated systems, and rapid communications across dispersed locations.
Europe is investing in alternatives. The EU’s IRIS² secure communications programme is intended to provide a sovereign European capability, while national governments are increasing spending on military satellite systems. Delivery will take time, leaving existing commercial constellations with significant operational importance in the interim.
The UK faces the same sequencing problem. Expanding domestic capability involves satellite manufacturing, launch capacity, spectrum, ground systems, secure integration, and long-term procurement. Defence users still need reliable connectivity while that infrastructure develops.
Commercial suppliers can provide speed and flexibility, but they shift parts of the resilience question from ownership towards contractual and technical safeguards. Governments have to consider continuity of access, pricing, cybersecurity, data handling, replacement hardware, interoperability, and service availability during geopolitical or commercial disruption.
The economics also differ between the two SpaceX services. Starshield carries substantially higher hardware and service costs than consumer-oriented Starlink because of the security and priority features required by government users.
Defence demand therefore represents a higher-value market built partly on infrastructure scaled through commercial broadband, while governments gain access to capabilities that would be expensive and slow to recreate independently.
The spending also illustrates the potential market for UK suppliers if sovereign programmes succeed. Satellite communications increasingly support defence resilience, logistics, intelligence, and command systems rather than operating as a specialist peripheral service.
Britain’s likely path is therefore one of gradual diversification rather than immediate replacement. SpaceX can meet current operational requirements while UK and European programmes build additional capacity and control over strategically important infrastructure.
The speed at which those sovereign systems become operational will determine how long the current level of dependence on commercial US satellite networks persists.
