| Summary | A medium-lift, kerosene/LOX launcher built specifically to deploy China's Guowang mega-constellation at high cadence from Wenchang's new commercial pads. | 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. | China's most-used sun-synchronous and polar orbit workhorse for small-to-medium military and commercial Earth observation satellites. Launched from Jiuquan and Taiyuan. Uses storable hypergolic propellants for high launch-readiness but produces toxic exhaust. |
