ArianeGroup Germany will assume responsibility for assembling the Vinci upper stage engine of the Ariane 6 launcher at DLR's Lampoldshausen location. Under an agreement signed on October 24, 2025, by representatives from ArianeGroup Germany, ArianeGroup France, and DLR, the site will handle the integration of key components such as turbopumps, valves, and thrust chambers.

Final testing on the fully assembled Vinci engines will be conducted using the P4.1 test stand at Lampoldshausen to ensure performance, reliability, and flight readiness. DLR and ArianeGroup collaborated closely to bring this transition about, consolidating Vinci's final production, system integration, and flight acceptance testing in Germany. Engine installation into the Ariane 6 upper stage will continue in Bremen.

DLR Executive Board Chair Anke Kaysser-Pyzalla emphasized the importance of Lampoldshausen as a pivotal European hub for propulsion systems, stating, "With our unique infrastructure and the strong commitment of our teams, we are making a decisive contribution to the future of European space transportation... Together, we are working on the further development of this exceptional space location."

Walther Pelzer, member of the DLR Executive Board and Director General of the German Space Agency at DLR, highlighted the site's strategic significance for advancing technology and retaining highly skilled jobs in Germany. Jens Franzeck, Chief Industrial Officer at ArianeGroup, noted that the Vinci engine embodies the Franco-German cooperation foundational to ArianeGroup, with design and certain components originating from France and development of thrust chambers in Ottobrunn, near Munich.

The Vinci engine is integral to Ariane 6's performance, offering multiple restarts, efficient fuel use with liquid hydrogen and oxygen, and support for diverse payload missions. Germany's contribution to the Ariane 6 project includes approximately EUR 800 million managed by the German Space Agency at DLR.

For over sixty years, Lampoldshausen has provided dedicated test benches for liquid rocket engines, making it essential for European access to space. Vinci's qualification on the Lampoldshausen P4.1 test stand before Ariane 6's first flight demonstrates the unique expertise available at the site. The relocation of assembly and sign-off testing to Lampoldshausen enhances the facility's role as a core center for space propulsion in Europe.
