| 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. | Russia's primary medium-lift workhorse, descended from the Soyuz family that has flown since 1966. Carries both crewed Soyuz spacecraft and Cygnus-class cargo. Fregat upper stage significantly expands mission flexibility. Production continues at Samara (now TsSKB-Progress). | 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. |
