| Summary | 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. | A Japanese commercial solid-fuel small launcher that has failed on all three flight attempts through March 2026, putting its commercial viability in serious question. | 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. |
