| Success rate | 0/1 (first flight failed)as of [1]First flight from Andøya Spaceport (2025-03-30): liftoff succeeded but the rocket was terminated ~30 seconds in after a vent valve opened unexpectedly, causing loss of attitude control. Second flight ('Onward and Upward') repeatedly delayed through 2026 (weather, a safety-zone fishing vessel, a composite pressure vessel leak, then off-nominal fluid-system behavior as of 2026-06-15) — not yet flown as of this research. | 100%as of [2]8/8 missions through VA269 Amazon Leo (Jun 17, 2026, 36 sats on upgraded P160C boosters); Ariane 64 debut Feb 12, 2026 ↑ Best | 0/3 — three consecutive failuresas of [1]2024-03-13: disintegrated shortly after liftoff. 2024-12-18: began tumbling during 1st-stage burn, flight terminated. 2026-03-04: flight termination activated ~70 seconds after liftoff. All three launches flew from Spaceport Kii, Wakayama — Japan's first private-sector spaceport.

| Summary | 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. | Europe's flagship launcher replacing Ariane 5. The Vinci re-ignitable upper stage enables multi-orbit missions and controlled deorbit. Primary customers: Amazon Kuiper, European government payloads, and ESA science missions. | 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. |
