| Summary | 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. | ULA's workhorse since 2002 and the longest-serving active US rocket. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Production ended in 2024 and ULA no longer sells the vehicle, but it continues flying a sold-out backlog of Starliner and Amazon Leo missions into the late 2020s. | ULA's triple-common-booster-core heavy-lift launcher, retired 2024-04-09 after its final flight; superseded by Vulcan Centaur, which ULA states offers similar heavy-lift capability at lower cost. |
