| 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. | 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. | Europe's primary small satellite launcher derived from Vega. The P120C first-stage motor is shared with Ariane 6's solid strap-on boosters. Avio took over programme management from Arianespace in Dec 2025. |
