Eutelsat Commits €3.39 Billion to Lead Europe’s IRIS² Satellite Constellation
Eutelsat announced a total investment commitment of €3.39 billion in IRIS², Europe’s secure-communications constellation. The first satellites of the 330-spacecraft low Earth orbit network will launch from 2029.
At a Glance
- Total commitment of €3.39 billion: €2.23 billion for shared IRIS² infrastructure, €1.16 billion for the commercial Ku-band payload and ground segment.
- The constellation counts 330 satellites: 264 with dual Mil-Ka/Ku-band payloads, 66 with Mil-Ka-band only.
- First Ka-band satellites launch from 2029; the commercial Ku-band network reaches full operation by mid-2032.
- Investment phased over 2027-2034; capacity revenue estimated above €10 billion through 2040.
- Airbus Defence and Space, Thales Alenia Space and Aerospacelab provide manufacturing capacity.
Europe’s Sovereign Constellation Push
IRIS² — the Infrastructure for Resilience, Interconnectivity and Security by Satellite — is the European Union’s low Earth orbit constellation for secure government and military communications. Eutelsat’s €3.39 billion commitment, announced on August 10, is the clearest signal yet that the program has moved from planning to execution. CEO Jean-François Fallacher called the milestone “a defining moment for Eutelsat and for Europe’s space ambitions.”
Of the total, €2.23 billion goes to the shared IRIS² infrastructure and €1.16 billion to Eutelsat’s commercial Ku-band payload and ground segment. The company projects more than €10 billion in capacity revenue between 2032 and 2040 under the initial concession agreement.
330 Satellites, Two Payload Tiers
The constellation comprises 330 spacecraft: 264 carrying dual military Ka-band and commercial Ku-band payloads, and 66 flying Mil-Ka-band payloads only. The first Ka-band satellites launch from 2029, with the commercial network fully operational by mid-2032. Airbus Defence and Space, Thales Alenia Space and Aerospacelab will build the satellites.
The program anchors Europe’s bid for a sovereign alternative in a LEO market dominated by Starlink and OneWeb — a dependence whose risks the war in Ukraine made unmistakable.
Why It Matters
IRIS² is one of the biggest tests of Europe’s claim to strategic autonomy in space. Eutelsat putting billions of its own capital at risk is the first major commercial guarantee that the program will not remain on paper.
