| Summary | 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. | A family of medium-lift launchers from SAST serving China's growing SSO/LEO commercial and government satellite demand, with the 6A and 6C variants adding solid boosters or a simplified expendable configuration respectively. | 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. |
