| Summary | 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. | The larger sibling of Kuaizhou-1A, roughly 3.75x the payload class, road-mobile and solid-fueled, recovering commercial cadence after a 2020 debut failure. | 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. |
