In Berlin, a new industrial alliance has set off alarm bells in Paris and Brussels, signalling that low‑Earth orbit is no longer just a field for cooperation, but a stage for rivalry between Europe’s own defence giants.
Germany is preparing a military satellite constellation in low‑Earth orbit that directly challenges France-backed Airbus and the EU’s flagship IRIS² secure connectivity programme. The project, currently dubbed “LEO‑MilSat”, is being driven by a new partnership between defence heavyweight Rheinmetall and satellite specialist OHB. Their aim: a sovereign, encrypted “military OneWeb” for German and potentially European armed forces, emergency services and critical infrastructure.
Berlin’s quiet revolution in orbit
The Rheinmetall–OHB alliance marks a sharp shift in how Germany sees space. For years, Berlin focused more on terrestrial hardware: tanks, munitions, air defence. Space was often treated as a supporting act. That era is ending.
Under the LEO‑MilSat concept, dozens or even hundreds of satellites would fly in low‑Earth orbit (typically 500 to 1,200 km above the surface). This architecture offers fast, low‑latency links and makes the network harder to knock out in a crisis.
LEO‑MilSat is designed less for streaming video and more for keeping commanders connected when ground networks are jammed, hacked or destroyed.
Military planners want resilient communications in scenarios where fibre-optic cables are cut, relay towers are hit, or hostile actors bombard frequencies with electronic warfare. A dense mesh of satellites can reroute data around damaged nodes, keeping command chains alive.
A “military OneWeb” with a German flag on top
Project insiders present LEO‑MilSat as a sovereign counterpart to commercial constellations like OneWeb and Starlink. It would be built under German leadership, with strict control over encryption, tasking and data routing.
The targeted users go beyond the Bundeswehr:
- Armed forces engaged in overseas missions or on NATO’s eastern flank
- Civil protection agencies responding to floods, wildfires or cyberattacks
- Operators of critical infrastructure such as power grids and rail networks
- Government services that need secure, high-availability links
For Rheinmetall, this is a strategic leap. The company wants to reposition itself from maker of armoured vehicles and ammunition to a central actor in European space defence. That fits NATO’s decision to recognise space as an operational domain alongside land, sea, air and cyber.

OHB, for its part, brings decades of experience in satellite platforms and mission design. After a period of restructuring and delisting from the stock market, the company is searching for a big flagship programme. LEO‑MilSat offers exactly that.
Rheinmetall contributes defence budgets, sensors and military integration; OHB delivers the orbital hardware and space know‑how.
Billions at stake in secure space connectivity
Behind the industrial romance sits a very hard number: tens of billions of euros. Secure satellite connectivity is one of the hottest markets in defence technology, combining cyber security, space hardware and communications.
Analysts expect spending on such systems to surge this decade, as states seek insurance against both kinetic attacks and digital threats. The ongoing war in Ukraine has shown how valuable constellations like Starlink can be when traditional infrastructure is disrupted.
Investors have noticed. Rheinmetall’s valuation has already been buoyed by rising defence orders. A strong position in space could help sustain that rally by broadening its portfolio beyond conventional arms. For OHB, LEO‑MilSat is a chance to reassert itself after losing some major institutional contracts in recent years.
| Programme | Lead country / actor | Main purpose | Estimated value |
|---|---|---|---|
| LEO‑MilSat (working name) | Germany (Rheinmetall–OHB) | Military and crisis communications | Several billion euros over decade |
| IRIS² | European Union, with Airbus among primes | EU‑wide secure connectivity, dual‑use | Around €10 billion envelope |
| OneWeb | UK‑based, operated by Eutelsat | Civil and governmental broadband | Multiple billions invested globally |
Airbus and IRIS² in the German crosshairs
This story really bites once Airbus Defence and Space enters the frame. Until now, Airbus has been the natural champion for big European satellite systems. The EU’s IRIS² project, designed as a secure connectivity layer for governments, businesses and critical services, was widely seen as its home turf.
IRIS², with a budget envelope estimated around €10 billion, aims to give the EU an answer to Starlink and other non‑European constellations. It mixes geostationary and low‑Earth orbit assets and is meant to serve both civilian and governmental users.
By pitching a German-run alternative just as IRIS² is ramping up, Rheinmetall is firing a warning shot directly across Airbus’s bow.
Industry insiders describe this as a form of “space war by tender”. For decades, large satellite contracts rotated among a small circle of primes, with France and Germany balancing influence. The LEO‑MilSat push suggests Berlin no longer wants to accept Airbus’s near-automatic leadership, particularly when French interests dominate.
The competition could intensify once procurement decisions for IRIS² follow-on segments and complementary systems are on the table. If Germany aligns its national spending behind LEO‑MilSat, it may seek to shape EU rules in favour of modular, interoperable constellations that leave room for its own project.
Europe caught between unity and fragmentation
The political dilemma for Brussels is stark. On one hand, EU leaders talk constantly about “strategic autonomy”: reducing dependence on US constellations like Starlink and limiting reliance on commercial solutions that could change terms overnight.
On the other, member states are pushing their own sovereign projects, driven by national industries and domestic politics. Germany’s LEO‑MilSat and France’s close ties to Airbus and Eutelsat pull in slightly different directions.
Rheinmetall plays this tension carefully. The company labels LEO‑MilSat as a fully European answer, while stressing that Germany will retain command over sensitive functions. That message reassures Berlin but raises questions in other capitals about data sharing, access priorities and control of encryption keys.
The risk is a patchwork of national constellations, each expensive to build, none large enough alone to match global competitors.
At the same time, a bit of industrial rivalry can push innovation. If Airbus, Rheinmetall and OHB all feel the heat, Europe might get more capable, more resilient satellite systems sooner than planned.
France’s uneasy position in low‑Earth orbit
Paris has been signalling for several years that space is no longer just about observation satellites and launchers. Under President Emmanuel Macron, France created a Space Command and has invested strongly in military space capabilities.
In secure communications, though, France has taken a more pragmatic route. It has backed Eutelsat’s involvement in OneWeb as a stopgap measure, giving European actors a stake in an existing low‑Earth orbit constellation while IRIS² is being developed.
That approach buys time but raises tough questions. Once IRIS² is operational and national projects like LEO‑MilSat are in orbit, how many separate constellations can European taxpayers sustain? Budget pressure could force governments to pick winners, turning today’s competition into tomorrow’s consolidation fight.
What a military LEO constellation actually does
For non‑specialists, talk of constellations and sovereignty can feel abstract. In practical terms, a LEO‑based military network gives commanders several concrete advantages.
- Shorter signal paths mean lower latency, useful for drone control or real-time targeting.
- Many small satellites create redundancy; losing a few to attacks or technical failures hurts less.
- Orbits can be tailored to focus coverage over Europe, the Arctic, or crisis regions.
- Dedicated government capacity reduces the risk that commercial users crowd out military traffic in wartime.
In a conflict scenario on NATO’s eastern flank, for example, ground fibre could be sabotaged and mobile networks overwhelmed or jammed. Units in the field would then rely on secure satellite terminals mounted on vehicles, ships or aircraft. Those terminals would automatically connect to whichever LEO‑MilSat node is overhead, hopping between satellites as they move.
Even in peacetime, such a system can support encrypted links for embassies, crisis response teams, maritime patrols or border surveillance aircraft.
Key terms behind the space confrontation
A few concepts matter for understanding this brewing contest:
Low‑Earth orbit (LEO): A band of space relatively close to Earth. Satellites here circle the planet in about 90–120 minutes. Their proximity allows for quicker communications and cheaper launches, but they need to be deployed in larger numbers for continuous coverage.
Secure connectivity: Military and government users need encrypted, authenticated links that resist jamming and spoofing. That requires both robust space hardware and sophisticated ground segment technology, including anti-jam antennas and hardened gateways.
Sovereignty of data: European states want to know where their data flows, who can access it, and under which jurisdiction. Using foreign-owned constellations makes that harder to guarantee, especially in a crisis involving those same powers.
As Germany advances its LEO‑MilSat plan and Airbus pushes IRIS², these technical issues turn into political arguments over whose equipment, whose software and whose keys sit at the heart of Europe’s next generation space infrastructure.
The coming years will show whether Berlin and Paris can align their ambitions around a shared architecture, or whether their “space war” hardens into separate constellations competing for the same sky and the same budgets.
