| Summary | ULA's triple-common-booster-core heavy-lift launcher, retired 2024-04-09 after its final flight; superseded by Vulcan Centaur, which ULA states offers similar heavy-lift capability at lower cost. | 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. | China's workhorse medium-lift rocket, used exclusively for Tianzhou automated cargo missions to the Tiangong space station. Designed to replace the Long March 2F for high-cadence LEO/cargo missions. Uses the same YF-100 engines as Long March 5's boosters. |
