| Summary | A Japanese commercial solid-fuel small launcher that has failed on all three flight attempts through March 2026, putting its commercial viability in serious question. | 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. | 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. |
