| Summary | 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. | A two-stage medium-lift launcher originally designed with a reusable combined-booster-recovery concept in mind, though currently operational vehicles fly expendable. Exclusively from Wenchang. | A family of medium-lift launchers from SAST serving China's growing SSO/LEO commercial and government satellite demand, with the 6A and 6C variants adding solid boosters or a simplified expendable configuration respectively. |
