| Summary | Currently the most powerful operational rocket in the world. Three Falcon 9 cores sharing propellant cross-feed produce 5.1 MN of sea-level thrust. Primary mission profile: DoD/NRO GEO payloads and planetary science. | 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. | 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. |
