| Summary | Galactic Energy's workhorse small-lift solid rocket — one of the most-flown Chinese commercial launchers — with a sea-launch variant (Ceres-1S, debuted Sep 2023) and a larger Ceres-2 in development. | 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. | Germany's first orbital-class launcher attempt; its first flight in March 2025 was Western Europe's first orbital launch attempt from the European mainland. A qualification second flight carrying CubeSats and ESA experiments has slipped repeatedly through 2026. |
