| Summary | ULA's workhorse from 2002–2024. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Its Russian RD-180 first-stage engine became a political liability after 2022; last flight was the Amazon Kuiper testbed on Apr 9, 2024. | 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. | 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. |
