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. | 75%as of [2]6/8 successes; VV22 (Dec 2022) Zefiro-40 failure destroyed Pléiades Neo 5&6; returned to flight VV25 (Dec 2024). 3 successes in 2025. ↑ Best | 43%as of [2]3/7 full successes (FLTA003 Jul 2023, FLTA005 Dec 2024, FLTA007 Mar 2026) + 2 partial successes + 2 failures through FLTA007 |

| 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 primary small satellite launcher derived from Vega. The P120C first-stage motor is shared with Ariane 6's solid strap-on boosters. Avio took over programme management from Arianespace in Dec 2025. | Firefly Aerospace's two-stage small-lift rocket powered by four Reaver engines at sea level and one Lightning engine in vacuum. Also provides launch services for NASA's CLPS programme (Blue Ghost lander launched on Falcon 9). FLTA007 'Stairway to Seven' succeeded Mar 11, 2026. |
