| 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. | 99.1%as of [2]108 full successes + 1 partial failure (NROL-30, Jun 2007 — payload still reached usable orbit) across 109 launches ↑ Best | ~95%as of [2]~6 failures/partial failures out of ~105+ flights; gradually being superseded by Long March 5 for GTO |

| 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. | ULA's workhorse since 2002 and the longest-serving active US rocket. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Production ended in 2024 and ULA no longer sells the vehicle, but it continues flying a sold-out backlog of Starliner and Amazon Leo missions into the late 2020s. | China's primary geostationary transfer vehicle for over 25 years. Launched communications, meteorology, and navigation satellites including Beidou-3 (GEO/IGSO nodes). Being phased out in favour of Long March 5 for heavier GTO payloads as newer domestic communications satellites grow in mass. |
