| Summary | 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. | 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. | Relativity Space's Falcon-9-class successor to Terran 1, partially 3D-printed, with 13 Aeon R methalox engines on a reusable first stage; second stage and fairing expendable. |
