BRUSSELS / RankWire.AI / – On Friday, European space authorities completed a significant expansion of the EU’s leading orbital communications system after months of extensive negotiations in Brussels. The European Commission officially announced the signing of a contract to broaden IRIS2 satellite constellation through a binding implementation agreement with the SpaceRISE industrial consortium. This formal agreement marks the end of detailed technical and financial discussions that started in January 2026, moving the Infrastructure for Resilience, Interconnectivity and Security by Satellite program from planning to large-scale industrial deployment.
According to the new agreement, the primary satellite network will increase from 282 planned orbital units to a total of 348 active spacecraft. The upgraded architecture incorporates 330 satellites in higher low Earth orbit along with 18 in medium Earth orbit, with additional orbital slots reserved for specialized missions. The implementation contract defines the key timetable for satellite production, launch procurement, ground segment development, and operational connectivity services. The initial satellite launches are scheduled for 2029, providing early sovereign connectivity for participating member states shortly thereafter.
This expansion directly responds to rising security needs and changing defense requirements across Europe. The updated design involves technical enhancements to the core satellite hardware, along with the addition of 66 low Earth orbit spacecraft intended for defense agencies, national security bodies, and emergency response teams. Technical evaluations indicate that this architectural upgrade will boost secure government communication capacity by 60 percent within the EU and by 54 percent worldwide, strengthening regional response capabilities during complex emergencies and infrastructure crises.
EU Commission Moves Forward with IRIS2 Satellite Constellation Expansion
The SpaceRISE consortium, which manages the main development efforts and 12-year operational rights, includes major European satellite operators such as SES, Eutelsat, and Hispasat. The public sector’s implementation is closely coordinated with the European Space Agency, which provides engineering support and launch management. Industrial manufacturing involves a broad network of European aerospace companies, including Thales Alenia Space, Airbus Defence and Space, and OHB, as well as telecommunications firms Orange and Deutsche Telekom.
Funding for the expanded satellite infrastructure relies on a public-private partnership model combining EU budget contributions, national government investments, and private industry funding from consortium members. Member states are in the process of formalizing their financial commitments for deployment over the 2028-2034 fiscal period. Government records show Poland has allocated 656 million euros, Hungary 500 million euros, and Spain has announced investments between 1.6 billion euros and 2 billion euros, with additional national funding negotiations ongoing.
Enhanced Technology to Improve Government Secure Communications by 60 Percent
The expanded system will also include nations outside the EU, such as Norway and Iceland, under separate administrative agreements. As the third major space initiative following Galileo and Copernicus, IRIS2 aims to provide high-quality, tamper-proof communication channels for public authorities, especially in remote areas. The network will utilize military-grade encryption standards across dedicated spectrum bands to protect critical infrastructure from cyber threats and physical interference.
With manufacturing now underway at European industrial facilities, the European Commission and SpaceRISE will oversee phased milestones leading to initial orbital tests. The signing of this contract ensures the expansion of the IRIS2 satellite constellation to meet long-term strategic goals of European autonomy. The resulting resilient, European-owned orbital infrastructure will support civil protection, defense missions, and commercial digital services for decades to come.
