| 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. | Japan's flagship medium-lift rocket for 24 years, retiring after an exceptional 49/50 mission success record. Launched the SELENE lunar orbiter (2007), Akatsuki Venus probe (2010), Hayabusa2 (2014), SLIM lunar lander (2023), and the ALOS series Earth observation satellites. | China's most powerful operational rocket and the backbone of its flagship space programs. Launched Tianwen-1 to Mars, Chang'e 5 sample return, Chang'e 6 far-side sample return, all Tiangong core and lab modules, and the Xuntian space telescope. The CZ-5B variant delivers entire station modules in a single flight. |
