European Union advances Iris² secure satellite communications program

The European Union is advancing its Iris² satellite constellation project, a strategic initiative designed to ensure autonomous and secure communications for defense, security, and emergency services. The program aims to deploy between 348 and 350 satellites across low and medium Earth orbits, with the first launches scheduled to begin in 2029. This infrastructure is intended to provide critical connectivity for government agencies—such as civil protection and emergency responders—while also offering commercial services to private telecommunications operators.

At a recent space summit in Paris, 22 European nations reaffirmed their support for the project, which seeks to reduce reliance on non-European systems like SpaceX’s Starlink. The development is being led by the SpaceRISE consortium, comprising Eutelsat, SES, and Hispasat, with industrial partners including Airbus Defence and Space and Thales Alenia Space.

While the project gains political momentum, it faces economic and industrial challenges. Estimated costs have risen from €10.6 billion in 2024 to approximately €15.7 billion. Additionally, discussions regarding national work-sharing and the distribution of industrial benefits among member states remain key considerations for the program’s long-term implementation. To bolster international cooperation, the EU has also signed an agreement with South Korea to enhance secure satellite communication capabilities.
