| 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. | 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. | A medium-lift successor to Firefly's Alpha, co-developed with Northrop Grumman, aimed at the national-security and commercial medium-lift gap between small launchers and heavy-lift vehicles. |
