| Summary | 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. | 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. | 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. |
