| 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. | Russia's dominant heavy-lift rocket for GEO comsats and planetary missions from 1965 (Proton family) through 2023 (Proton-M). Notorious for its hypergolic propellant — a highly toxic UDMH/N₂O₄ combination that caused environmental concerns at Baikonur. Replaced by Angara A5. | 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). |
