| Summary | Europe's flagship launcher replacing Ariane 5. The Vinci re-ignitable upper stage enables multi-orbit missions and controlled deorbit. Primary customers: Amazon Kuiper, European government payloads, and ESA science missions. | Europe's dominant heavy-lift rocket for 27 years. Its most famous payload: the James Webb Space Telescope (Dec 25, 2021). Retired Jul 5, 2023 to make way for Ariane 6. Responsible for launching over 250 commercial and scientific payloads including XMM-Newton, Rosetta, and BepiColombo. | JAXA's small solid-fuel rocket derived from the M-V rocket heritage. Designed for highly autonomous operations — launch preparations could be managed by just 8 people. The sixth and final E-6 mission (Oct 2022) failed when the PBS kick stage didn't ignite; a ground explosion during Epsilon S testing (Jan 2023) ended the programme. |
