Europe's IRIS² Satellite Network: Cost, Delays, Germany

The European Union’s IRIS² satellite network will cost Europe a great deal before it serves a single paying customer, and its schedule already faces strain. The Commission and the SpaceRISE consortium agreed on implementation in early August. The plan calls for 348 satellites: 330 in low Earth orbit, 18 in medium Earth orbit, and a further 66 intended for defence, security and emergency services.

The pitch is sovereignty. IRIS², short for Infrastructure for Resilience, Interconnectivity and Security by Satellite, is meant to provide secure connections for governments, companies and citizens, while closing mobile coverage gaps in Europe and Africa. The network will rely on quantum technology for encryption through the European quantum communication infrastructure EuroQCI. The Commission projects a 60 percent increase in secured capacity for public-sector users in the EU and a 54 percent increase worldwide. Those are ambitious numbers for a network whose first satellites won’t go up until 2029.

The Schedule Problem

The first satellites are scheduled to launch in 2029, with initial services introduced gradually from 2029 or 2030. Media reports said the original plan called for launches two years earlier. That slippage matters: Europe is racing a commercial rival that already operates in orbit.

The bottleneck isn’t only satellites. It’s rockets. Satellites can’t reach space without launch vehicles, leaving operators that can’t launch their own dependent on others. Europe relies on Ariane 6, which has launched since 2024 and has flown four times so far this year. Three flights carried satellites for Amazon Leo, the US company’s internet service intended to compete with Starlink. Amazon has booked at least 18 Ariane 6 launches. Andreas Knopp of the Bundeswehr University Munich told the weekly paper Das Parlament that the number of launches is limited. Political scientist Antje Nötzold of TU Chemnitz described a “launcher problem” to MDR.

Germany’s Share and the Money

Germany’s industrial stake caused friction early. In December 2023, the Federal Ministry for Economic Affairs sent companies involved a strongly worded letter demanding urgent clarification of German industry’s participation and its share in value creation, the Frankfurter Rundschau reported. The taxpayer deserves an answer before the money is spent, not after.

Bremen-based Orbitale Hochtechnologie Bremen (OHB) has moved to secure its position. On 31 August, it signed a contract worth just under €1 billion with satellite operator SES for 18 IRIS² satellites in medium Earth orbit, each weighing around 2.6 tonnes at launch. OHB chief executive Marco Fuchs sees the programme as an important step towards greater European independence. Belgium’s Aerospacelab, founded in 2018 and based in Charleroi, is building 264 low-orbit satellites under an order it says is worth €2.4 billion, with delivery by 2030. Airbus is building at least 66 satellites in the first layer for military communication, due in 2029.

Sovereignty and the Starlink Question

The case for building this network rests on what happened this week. The Ukrainian army reported restrictions to Starlink: connections drop when receivers travel faster than 160 kilometres per hour, as drones do. The service returned partly, but an upper limit remained, and it’s unclear who ordered it. SpaceX boss Elon Musk denied that the company ordered the shutdown, writing on X that Starshield is under the direct control of the US government. Polish foreign minister Radosław Sikorski wrote on X: “Hey, Elon Musk, you big man, are you once again playing politics with your products? As your European customers we are keeping a close eye on you.” Poland has paid for a large share of the Ukrainian terminals.

Germany’s Bundeswehr is pursuing its own track. Major General Armin Fleischmann, the Bundeswehr’s space commissioner, told MDR the plan is for a constellation similar to Starlink but smaller. The SATCOMBw 4 project, at full expansion a three-digit number of low-orbit satellites, would cost between eight and ten billion euros. An initial partial constellation of up to 40 satellites is scheduled for 2029, with full operations planned from 2030. The joint venture OHB Rheinmetall Space Networks is bidding: OHB will build the satellites, while Rheinmetall handles ground stations and end devices. No decision has been taken, though industry reports suggest an award around the turn of the year, and insiders consider early 2027 possible.

The Bundeswehr’s existing military satellites show how long these programmes run. COMSATBw-1 and COMSATBw-2, launched in 2009 and 2010, still orbit at around 36,000 kilometres. Airbus is building their successors, scheduled for handover in orbit in 2029.

Why This Matters: Europe is spending heavily to avoid dependence on a single private provider, and the bill runs into the billions across several national and EU budgets. The Ukrainian Starlink episode gave that argument force, but it also exposed how thin launch capacity is. IRIS²’s success depends less on political declarations than on whether Ariane 6 can fly often enough and whether the Commission, Berlin and industrial partners keep costs and timelines in check. Taxpayers and member states should judge the programme by its delivery dates and value for money, not ambition alone. Sovereignty is real only when the capability works, remains affordable, and belongs to those who pay for it.
