| 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. | Relativity Space's Falcon-9-class successor to Terran 1, partially 3D-printed, with 13 Aeon R methalox engines on a reusable first stage; second stage and fairing expendable. | A liquid-biomethane orbital smallsat launcher from Interstellar Technologies, Japan's most established private rocket startup by suborbital flight heritage, though not yet flown to orbit. |
