| 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. | South Korea's first domestically developed and produced launch vehicle, designed entirely without foreign engine technology. Nuri TF4 (Nov 2025) was the first launch managed by Hanwha Aerospace rather than KARI — marking the transition to commercial operation. KASA (Korea Aerospace Administration) took over programme oversight in 2024. | 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. |
