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. | — | 43%as of [2]3/7 full successes (FLTA003 Jul 2023, FLTA005 Dec 2024, FLTA007 Mar 2026) + 2 partial successes + 2 failures through FLTA007 ↑ Best |

| 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. | Rocket Lab's medium-lift reusable rocket targeting the $100B constellation replenishment market. Uses a 'hungry hippo' fairings design that opens at the top rather than traditional clamshell separation. First flight delayed to Q4 2026 after a Jan 2026 propellant tank test anomaly. | 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. |
