| Summary | 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. | 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. | The world's most commercially active small launch vehicle, designed and built in-house at Rocket Lab. Rutherford engines are the first flight-proven engines made with additive manufacturing (metal 3D printing). Booster recovery via parachute and helicopter catch (later transitioned to ocean recovery). |
