| 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. | ULA's triple-common-booster-core heavy-lift launcher, retired 2024-04-09 after its final flight; superseded by Vulcan Centaur, which ULA states offers similar heavy-lift capability at lower cost. | Germany's first orbital-class launcher attempt; its first flight in March 2025 was Western Europe's first orbital launch attempt from the European mainland. A qualification second flight carrying CubeSats and ESA experiments has slipped repeatedly through 2026. |
