| 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. | 97.5%as of [2]113/117 successes.

| 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 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. | The larger sibling of Kuaizhou-1A, roughly 3.75x the payload class, road-mobile and solid-fueled, recovering commercial cadence after a 2020 debut failure. |
