| 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. | Russia's replacement for the Ukrainian-built Zenit, restoring medium-lift capability lost after 2014. Uses the RD-171MV — described as the most powerful liquid-fuel rocket engine in the world — on its first stage, launching from Baikonur. | Firefly Aerospace's two-stage small-lift rocket powered by four Reaver engines at sea level and one Lightning engine in vacuum. Also provides launch services for NASA's CLPS programme (Blue Ghost lander launched on Falcon 9). FLTA007 'Stairway to Seven' succeeded Mar 11, 2026. |
