| 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. | LandSpace's enhanced methalox launcher, the higher-performance successor to the original Zhuque-2 (the first methalox rocket ever to reach orbit, in 2023) — see slug 'zhuque-2' for the original vehicle already in our database. |
