The European Commission has moved its IRIS² secure satellite programme into full-scale deployment, expanding the planned constellation by 66 satellites as Europe attempts to turn years of digital sovereignty policy into functioning communications infrastructure.

An implementation agreement signed with the SpaceRISE consortium on 7 August concludes negotiations that began in January and fixes the programme’s revised design, capacity, deployment timetable, target pricing, and private-sector investment commitments. The main constellation will now comprise 348 satellites, including 330 in low Earth orbit and 18 in medium Earth orbit, with further optional elements available for specific missions.

The additional 66 satellites will form a dedicated layer aimed at defence, security, and emergency users, reflecting the way Europe’s secure connectivity ambitions have become more closely tied to resilience and military requirements. The Commission says the revised design will increase secure governmental communications capacity by 60% inside the EU and by 54% globally.

First launches are scheduled for 2029, while operational connectivity services are expected to begin progressively from the same period. SpaceRISE brings together SES, Eutelsat, and Hispasat, with Airbus Defence and Space, Thales Alenia Space, OHB, Aerospacelab, and other European suppliers participating across the wider industrial programme.

Sovereignty now requires hardware

European policymakers have spent several years treating cloud infrastructure, semiconductors, artificial intelligence, and connectivity as questions of strategic dependence, but satellite communications make the physical consequences unusually visible. A sovereign service cannot be created by regulation alone because satellites have to be designed, financed, manufactured, launched, operated, accredited, and connected to secure terrestrial infrastructure before governments can depend on them.

IRIS², short for Infrastructure for Resilience, Interconnectivity and Security by Satellite, is intended to give European governments and authorised users an alternative layer of secure communications when terrestrial networks are unavailable, disrupted, or unsuitable for sensitive traffic. Emergency response, defence operations, critical infrastructure protection, and communications in remote regions all sit within that remit.

The latest agreement therefore moves attention from whether Europe should build such a system towards whether its institutions and industrial partners can deliver one on the revised timetable. That is a materially different stage from the negotiations Techopia examined in July through SES’s role in European sovereign connectivity, when the commercial and political case was already established but significant implementation details remained open.

By fixing the expanded architecture and moving towards satellite construction, launch procurement, secure ground infrastructure, and service deployment, the agreement gives European manufacturers a clearer pipeline of work. It also turns IRIS² into an industrial policy programme as well as a communications project, with contracts and technical requirements flowing through large aerospace companies and potentially into specialist suppliers, startups, and mid-sized technology businesses.

Security has changed the specification

The expansion also demonstrates how geopolitical conditions can alter infrastructure requirements while a programme is still being designed. The additional 66 satellites are explicitly intended to strengthen defence, security, and emergency capability, while the Commission says the overall constellation has been revised to provide greater resilience and more governmental capacity than originally planned.

Secure communications have become more prominent across European defence planning as governments confront cyberattacks, physical sabotage, jamming, disrupted infrastructure, and the operational lessons of conflicts in which commercial satellite services have played a substantial role. Dependence on externally controlled communications networks can create political as well as technical exposure, particularly when a provider can influence service availability or commercial terms during a crisis.

IRIS² is intended to reduce part of that dependence, although Europe will still operate within a global satellite, launch, semiconductor, and communications supply chain. Sovereignty in this context is less about technological isolation than retaining sufficient control over critical infrastructure, contracts, capacity, and governance to keep essential services available when commercial or geopolitical conditions deteriorate.

The programme also builds on EU GOVSATCOM, which became operational in January and pools secure satellite capacity from participating member states. GOVSATCOM provides an interim layer while IRIS² is constructed, and its hub is expected eventually to act as an access point for governmental IRIS² services.

Execution becomes the harder test

Moving into implementation does not remove the risks attached to a project of this scale because satellite programmes carry long development cycles, substantial engineering requirements, launch dependencies, and cost exposure. The first launches remain three years away, while services will need accreditation and integration into government systems before the constellation can fulfil its resilience objectives.

Commercial questions will run alongside those governmental requirements. SpaceRISE’s members are established satellite operators rather than a newly created public utility, so the programme has to combine public security objectives with an industrial structure intended to attract private investment and support commercial connectivity services.

Europe is also building IRIS² while the commercial low-Earth-orbit market continues expanding elsewhere, meaning the programme will enter a sector where other networks already operate at substantial scale. Competing satellite-for-satellite with existing global constellations is not its central purpose, however, because secure government connectivity, accreditation, European operational control, and resilience sit at the centre of the design.

With the architecture expanded and the implementation agreement signed, IRIS² has crossed from sovereignty strategy into an engineering and delivery programme. Factories now have to build the satellites, launch capacity must be secured, ground systems have to work, and European governments ultimately have to be able to rely on the resulting network when terrestrial communications cannot be taken for granted.
