Eutelsat selects Arianespace for two upcoming OneWeb launches

• Two dedicated Ariane 64 launches secured for 2027 and 2028
• Supporting the renewal and service continuity of Eutelsat’s OneWeb LEO network
• Adding further European launch capacity to Eutelsat’s diversified options for access to Space

Paris, 10 September 2026 – Eutelsat (ISIN: FR0010221234 – Euronext Paris / London Stock Exchange: ETL) has selected Arianespace to conduct two dedicated launches for its OneWeb Low Earth Orbit (LEO) constellation.

Scheduled for 2027 and 2028, the missions will launch OneWeb satellites aboard Ariane 64 rockets, the most powerful version of Ariane 6, from Europe’s Spaceport in French Guiana.

The two missions support Eutelsat’s plan to progressively renew the OneWeb constellation and ensure service continuity of its LEO services, with 440 satellites already procured and under construction.

Together with launch capacity already secured through other providers, they provide additional diversity and flexibility in Eutelsat’s access to space options as it manages the deployment of future satellites. The missions will also support preparations for the next phase of Eutelsat’s LEO roadmap, including in the IRIS² programme.

Arianespace has supported the expansion of Eutelsat’s GEO fleet and the initial deployment of OneWeb. The new missions extend that longstanding relationship, bringing together strategic European capabilities in satellite communications and access to space.

Jean-François Fallacher, Chief Executive Officer of Eutelsat, said: “Access to space is a critical enabler for a satellite operator. Eutelsat and Arianespace have a long and important history in both GEO and LEO, and we are delighted to take this partnership into its next chapter. These launches will play an important role as we renew OneWeb and secure the long-term future of our LEO network. They also bring together two critical European capabilities -- satellite connectivity and access to space -- reinforcing Europe’s resilience and independence in space.”

David Cavaillolès, CEO of Arianespacesaid, “We are particularly proud to be working with Eutelsat once again, having supported the deployment of OneWeb from its earliest stages. This agreement opens a new chapter in the shared history of Arianespace and Eutelsat, while demonstrating Ariane 6’s ability to meet the needs of large LEO constellations. It also goes to the heart of our mission: giving Europe autonomous access to space and the launch capability to deploy its most strategic infrastructure.”
