| Summary | Japan's next-generation flagship rocket designed to halve H-IIA costs. Uses three LE-9 engines burning liquid hydrogen — the highest-performing expander-cycle engines in the world. First successful flight was TF2 (Feb 17, 2024). HTV-X1 cargo mission to ISS (Oct 2025) demonstrated operational readiness. | Europe's dominant heavy-lift rocket for 27 years. Its most famous payload: the James Webb Space Telescope (Dec 25, 2021). Retired Jul 5, 2023 to make way for Ariane 6. Responsible for launching over 250 commercial and scientific payloads including XMM-Newton, Rosetta, and BepiColombo. | Russia's dominant heavy-lift rocket for GEO comsats and planetary missions from 1965 (Proton family) through 2023 (Proton-M). Notorious for its hypergolic propellant — a highly toxic UDMH/N₂O₄ combination that caused environmental concerns at Baikonur. Replaced by Angara A5. |
