| 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. | The next evolution of ESA's Vega line: replaces the Zefiro-9 and AVUM+ stages with a single cryogenic LOX/methane upper stage powered by the new M10 engine, adding multi-orbit deployment flexibility. First flight is a stated target (2027), not yet flown. | 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. |
