| Summary | 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. | 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. | Russia's primary medium-lift workhorse, descended from the Soyuz family that has flown since 1966. Carries both crewed Soyuz spacecraft and Cygnus-class cargo. Fregat upper stage significantly expands mission flexibility. Production continues at Samara (now TsSKB-Progress). |
