Arianespace announced at the European Space Conference in Brussels the signature of the launch contract with the European Union Agency for the Space Programme (EUSPA), under the delegation of the European Commission, to orbit the second pair of second-generation satellites of the Galileo constellation (Galileo L18) on board an Ariane 6 launcher. With this signature, the European Commission and the EUSPA are formalising the launch contract of Galileo L18, following the initial mission allocation to Arianespace made in April 2024.
The launch of Galileo L18 will represent Ariane 6's fifth mission for Europe's high-precision global navigation satellite system. On December 17th, 2025, Ariane 6 successfully orbited for the first time, and with the utmost accuracy, a pair of satellites for Galileo (Galileo L14). Two other Ariane 6 launches are scheduled to complete the first-generation of Galileo satellites with the launch of the Galileo L15 and Galileo L16 missions. The fourth Galileo Ariane 6 flight will put into orbit the first pair of second-generation Galileo satellites (Galileo L17).
David Cavaillolès, CEO of Arianespace, commented: “This signature with the European Commission and EUSPA underscores Arianespace's commitment to guaranteeing Europe's sovereign access to space. Just last month, the successful and precise launch of two Galileo satellites showcased Ariane 6's accuracy and relevance for such critical missions. We are extremely proud of our long-standing partnership with our European partners, which enables the flagship Galileo global navigation satellite system to provide high-precision positioning and services to governments, institutions, and citizens worldwide.”
Rodrigo da Costa, EUSPA Executive Director, said: “This new launch contract builds on last year's first agreement for Galileo's second generation, demonstrating continuity and EUSPA's long-term commitment to its expanded role, including launch activities. It reinforces our responsibility for delivering precise and reliable services while strengthening the Union's space autonomy for users worldwide.”
Timo Pesonen, Director-General of DEFIS, European Commission, said: “The Galileo programme is a cornerstone of Europe's strategic autonomy. This new launch contract, implemented by EUSPA with Arianespace under delegation of the European Commission, confirms our commitment to a robust, secure, and fully European navigation system, while Ariane 6 demonstrates Europe's capacity to guarantee reliable and independent access to space for critical infrastructures.”
