| 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 next-generation medium-heavy rocket replacing Atlas V. Powered by two BE-4 engines on the first stage and a cryogenic Centaur V upper stage. Primary customer is USSF under NSSL Phase 2. | The world's most frequently flown orbital rocket. Block 5 first stages have landed over 280 times and reflown up to 23 times. Backbone of Starlink and commercial crewed launches. |
