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. | 78%as of [2]~7/9 successes.

| Summary | 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. | 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. | Japan's next-generation flagship rocket designed to halve H-IIA costs. Uses LE-9 engines burning liquid hydrogen — the highest-performing expander-cycle engines in the world. First flight TF1 (Mar 7, 2023) failed; first success was TF2 (Feb 17, 2024). HTV-X1 cargo mission to ISS (Oct 2025) demonstrated operational readiness, and the solid-booster-free H3-30 variant debuted Jun 12, 2026. |
