Germany is pressing ahead with a €10 billion military satellite network built with Rheinmetall, OHB and Airbus, triggering a sharp debate within the European Union over whether Berlin is bolstering the continent’s defence capabilities or quietly undermining them by building a parallel system that duplicates an EU project already under way.
The friction sits at the intersection of two expensive ambitions. The EU’s IRIS² programme — a €10.6 billion constellation of 290 satellites designed to give Europe a unified, space-based communications network independent of American infrastructure — is the bloc’s most significant collective defence investment in a generation. Germany’s proposed 100-satellite network, running in low-Earth orbit and designed exclusively for military communications, would sit alongside IRIS² rather than within it. To supporters, that is strategic redundancy in an era of rising threats. To critics, it is a €10 billion exercise in fragmentation that Europe cannot afford.
“If Germany now builds a purely national architecture that is not integrated into IRIS², there is a risk of weakening European structures,” Marie-Agnes Strack-Zimmermann, chair of the European Parliament’s security and defence committee, told Reuters. The warning came from one of the EU’s most prominent voices on defence policy — a German lawmaker, notably, criticising her own government’s approach.
The technical architecture Germany has in mind draws on technology comparable to Elon Musk’s SpaceX Starshield platform, the military communications constellation that has underpinned Ukraine’s battlefield connectivity since Russia’s invasion. The parallel is deliberate and instructive: Starshield demonstrated what a purpose-built, low-Earth-orbit military network can do in active conflict. Berlin wants that capability sovereign, under German control, with performance parameters that a Berlin government spokesperson described as “entirely different” from what IRIS² is designed to deliver.
That argument — that the two systems serve genuinely distinct functions and are therefore complementary rather than competitive — is the core of the German defence. IRIS², the spokesperson noted, “has the potential, where appropriate, to complement national initiatives in fulfilling sovereign tasks.” The language is carefully hedged, as government language tends to be when the actual position is that national requirements override collective frameworks.

OHB chief executive Marco Fuchs, whose company stands to benefit from the German contract, was more direct. Military communications cannot be procured the way civilian bandwidth is leased. “If there is a genuine military requirement, you cannot simply say: ‘I’ll rent it from private companies and wait to see how the conditions turn out,'” he said. The remark was aimed at IRIS², which relies on public-private partnerships and is designed to carry commercial traffic alongside its military functions — an architectural choice that purists argue compromises the network’s military utility.
The economics are where critics find their sharpest ground. Jeanne Dillschneider, the Green Party’s rapporteur on the Bundestag’s defence committee, observed simply that “the taxpayer will ultimately pay the bill” — a reminder that sovereign capability comes at sovereign cost, and that Germany’s fiscal position, already stretched by rearmament commitments, does not make duplication comfortable. Christophe Grudler, a European Parliament lawmaker focused on defence and space policy, argued that a smaller national constellation would deliver less coverage and less scalability than an integrated European system, at greater cost per capability unit. “Fragmentation is rarely the most efficient use of public resources,” he said.
The Alternative for Germany party took the opposing view, reframing the entire debate. Redundancy, AfD defence spokesperson Ruediger Lucassen argued, is not inefficiency — it is basic military prudence. In a conflict environment where adversaries have demonstrated both the intent and the capacity to disrupt or destroy satellite systems, having only one network, however large, is a single point of failure. “Redundancy — in military terms, reserves — is not a waste of money but a requirement of responsible national security policy,” he said.
The argument has merit that transcends AfD’s political positioning. Modern warfare’s dependence on space-based communications, demonstrated graphically in Ukraine, has made satellite constellations both indispensable and vulnerable. Russia has invested heavily in counter-satellite capabilities. China has done the same. A Europe that concentrates its military communications in a single programme, however well-designed, is betting that programme will survive a conflict in which adversaries will specifically target it.
Italy is watching Germany’s initiative and exploring its own domestic low-Earth-orbit network with both military and civilian applications, though Rome’s project remains at an early feasibility stage well behind Berlin’s planning. If Germany proceeds, it may set a precedent that other large EU members follow — each building national constellations alongside IRIS², each citing sovereign requirements, each drawing down the political and financial capital available for collective European defence architecture.

The European Commission has declined to weigh in directly, with a spokesperson noting that investments by individual member states are a national responsibility while reiterating the efficiency arguments for IRIS².
IRIS² is not expected to reach full deployment until the 2030s — a timeline that defence planners increasingly regard as dangerously slow given the pace at which the European security environment has deteriorated.
Grudler, despite his objections to fragmentation, acknowledged the urgency: “Europe must accelerate.” His concern is that national alternatives will not solve the timeline problem and will compound the coordination problem.
What Germany is proposing is, in the end, a bet on national capability over collective coherence — a bet that a purpose-built military network under Berlin’s exclusive control is worth the friction it generates with partners who believe the EU’s collective architecture is the only viable long-term answer. Both sides of that argument are making it simultaneously, in Brussels and Berlin, while the satellites they are arguing about have not yet been built.
