| Summary | CASIC's road-mobile, quick-response small solid launcher, operated commercially by ExPace since 2017 — one of the higher-cadence Chinese small-lift vehicles. | Japan's next-generation flagship rocket designed to halve H-IIA costs. Uses LE-9 engines burning liquid hydrogen — the highest-performing expander-cycle engines in the world. First flight TF1 (Mar 7, 2023) failed; first success was TF2 (Feb 17, 2024). HTV-X1 cargo mission to ISS (Oct 2025) demonstrated operational readiness, and the solid-booster-free H3-30 variant debuted Jun 12, 2026. | The next evolution of ESA's Vega line: replaces the Zefiro-9 and AVUM+ stages with a single cryogenic LOX/methane upper stage powered by the new M10 engine, adding multi-orbit deployment flexibility. First flight is a stated target (2027), not yet flown. |
