| Summary | 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 primary geostationary transfer vehicle for over 25 years. Launched communications, meteorology, and navigation satellites including Beidou-3 (GEO/IGSO nodes). Being phased out in favour of Long March 5 for heavier GTO payloads as newer domestic communications satellites grow in mass. | A liquid-biomethane orbital smallsat launcher from Interstellar Technologies, Japan's most established private rocket startup by suborbital flight heritage, though not yet flown to orbit. |
