| 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. | Primary launch vehicle for Cygnus ISS cargo missions from 2013–2023. Its Ukrainian-built Zenit-derived first stage and Russian RD-181 engines became untenable after the 2022 invasion of Ukraine. Northrop switched NG-20 onward to Falcon 9 while Antares 330 (with Firefly Miranda engines) is in development. | Firefly Aerospace's two-stage small-lift rocket powered by four Reaver engines at sea level and one Lightning engine in vacuum. Also provides launch services for NASA's CLPS programme (Blue Ghost lander launched on Falcon 9). FLTA007 'Stairway to Seven' succeeded Mar 11, 2026. |
