Behind Europe’s EUR 15.6 billion IRIS² deal: three key questions on funding, supply chain, and strategic positioning

In August, the European Commission and the SpaceRISE consortium signed the implementation agreement for IRIS², officially moving Europe’s sovereign connectivity constellation from planning into deployment.

The project is now priced at EUR 15.6 billion, with the constellation expanding from 282 to 348 satellites—including 330 in low Earth orbit and 18 in medium Earth orbit.

This is more than a satellite program. It is Europe trying to do three things at once: secure funding, reorganize its industrial supply chain, and redefine its position in the satellite communications market.

1. The funding question: the contract is signed, but EUR 11.6 billion is still not fully locked in

The biggest issue for IRIS² is not that it is expensive. The real issue is how the money will actually be secured.

When the project was proposed in 2022, the estimated cost was around EUR 6 billion. By 2024, that had risen to EUR 10.6 billion. It has now reached EUR 15.6 billion—roughly a 2.6x increase in three years.

The reason is straightforward: IRIS² has evolved into something closer to a sovereign security infrastructure program, rather than just a communications constellation. More satellites and more system capability are being directed toward secure government communications, resilience, and anti-jamming capacity.

Out of the total EUR 15.6 billion:

the SpaceRISE consortium is expected to contribute up to EUR 4 billion
the remaining EUR 11.6 billion will need to come from the European Commission, ESA, member states, and participating countries

And this is where the real uncertainty lies.

That EUR 11.6 billion currently exists more as a headline commitment than as a fully defined annual funding plan. The actual budget allocations will need to be embedded in the EU’s 2028–2034 multiannual financial framework.

In other words, the contract is in place, but the financing loop is not yet fully closed.

2. The supply chain question: responsibilities are clear, but launch remains the real bottleneck

On paper, Europe has now built a fairly clear industrial structure for IRIS².

Eutelsat is leading the low Earth orbit segment
Hispasat is responsible for the ground segment and selected specialized LEO capabilities
SES is leading the medium Earth orbit segment, user terminals, and operational services

On the manufacturing side, companies such as Airbus Defence and Space, Thales Alenia Space, OHB, and Aerospacelab are all part of the picture.

But the tightest constraint in the supply chain may not be satellite production. It may be launch capacity.

The 348 satellites are expected to rely mainly on Ariane 6, with industry estimates pointing to 10 to 15 launches. Ariane 6 is still ramping up, and Europe has only recently emerged from a period of launch capability disruption.

IRIS² is targeting its first launch in 2029. Whether that milestone can be met will depend heavily on whether Europe can translate policy ambition into reliable launch cadence.

So the key supply chain challenge is not only who builds the satellites, but also who can put them into orbit on time.

3. The strategic question: Europe is not trying to replicate Starlink — it is trying to secure sovereign access

Comparing IRIS² with Starlink purely by satellite count misses the point.

Europe is not trying to win a direct, commercial-scale war on mass broadband connectivity. IRIS² is about building a European-controlled secure communications architecture for governments, defense, emergency response, and critical infrastructure.

Its core value proposition is not sheer scale but control, encryption, resilience, and continuity under crisis conditions.

That also explains why Europe is moving on two fronts at the same time:

internally, operators, manufacturers, and public institutions are aligning around a shared industrial and strategic project
externally, Europe is trying to preserve room for its own companies through spectrum, market access, and regulatory frameworks

IRIS² is therefore not just a constellation program. It is also an industrial policy instrument.

What to watch next

For IRIS², the real test will not be political messaging but execution.

Three milestones matter most:

Whether the EUR 11.6 billion is fully anchored in the EU’s long-term budget with clear appropriations
How prime contracts and subcontracting work are allocated across Europe’s industrial base
Whether the 2029 first-launch target can actually be delivered

If those three pieces fall into place, IRIS² will move from political intent to genuine industrial reality.

At its core, this EUR 15.6 billion program is not just about deploying 348 satellites. It is about Europe placing a long-term bet on sovereign connectivity.
