| 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. | Russia's primary medium-lift workhorse, descended from the Soyuz family that has flown since 1966. Carries both crewed Soyuz spacecraft and Cygnus-class cargo. Fregat upper stage significantly expands mission flexibility. Production continues at Samara (now TsSKB-Progress). | LandSpace's enhanced methalox launcher, the higher-performance successor to the original Zhuque-2 (the first methalox rocket ever to reach orbit, in 2023) — see slug 'zhuque-2' for the original vehicle already in our database. |
