| 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. | Europe's dominant heavy-lift rocket for 27 years. Its most famous payload: the James Webb Space Telescope (Dec 25, 2021). Retired Jul 5, 2023 to make way for Ariane 6. Responsible for launching over 250 commercial and scientific payloads including XMM-Newton, Rosetta, and BepiColombo. | 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. |
