| 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. | 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. | Russia's new-generation heavy-lift rocket built entirely of Russian-manufactured components — a political priority after Proton-M's dependence on Ukrainian components. Five URM-1 universal rocket modules share the same propellant (RP-1/LOX), unlike Proton-M's toxic hypergolics. Flight rate remains very low. |
