| 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. | 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. | 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). |
