Europe's IRIS² Satellite Network Advances with German Leadership in Defense Strategy

The European Union has taken a decisive step to bolster its strategic autonomy by advancing the IRIS² satellite network, a €35 billion initiative designed to shield European communications from foreign dependency and enhance military resilience.

The IRIS² constellation will consist of 348 satellites—330 in low Earth orbit and 18 in medium Earth orbit—offering secure, high-capacity communications for EU governments and critical services. This move follows concerns raised by the limitations of foreign-operated networks, such as Starlink, during recent conflicts including the war in Ukraine.

Germany plays a pivotal industrial role through OHB, the Bremen-based aerospace company, which secured a contract worth just under €1 billion with SES to deliver 18 medium Earth orbit satellites. With each satellite weighing 2.6 tonnes at launch, these units form the backbone of IRIS²’s public-sector infrastructure. Belgian firm Aerospacelab is responsible for another 264 satellites, while Airbus will supply at least 66 satellites dedicated to military communications.

The first IRIS² satellites are scheduled for launch in 2029, with initial services coming online gradually from late 2029 or 2030. The network is expected to increase secured capacity for European public-sector users by 60%. For Germany, IRIS² complements the Bundeswehr’s own SATCOMBw satellite project, which has an estimated budget of €8–10 billion and targets full deployment by 2030.

The European Commission’s backing of IRIS² reflects a broader commitment to reinforce the bloc’s defense and technological capabilities. The project not only seeks to protect sensitive communications but also to catalyze growth in the European aerospace sector by supporting local manufacturers and operators.

However, the deployment timeline faces risks, notably the limited availability of launch vehicles, with dependence on the Ariane 6 rocket potentially causing delays. Despite these logistical challenges, industry and policymakers view IRIS² as a critical step in ensuring that Europe, Latin America’s key partner in technology and security, remains competitive and resilient in an era of geopolitical uncertainty.
