| Success rate | ~55%as of [2]IFT-1 through IFT-11; ~6 complete mission successes, remainder partial or vehicle lost. No orbital payload deployment yet. | 75%as of [2]~6/8 successes. TF1 (Feb 2023) first flight failure (LE-9 ignition issue, DAICHI-3 lost). F8 (Dec 23, 2025) QZS-5 lost to 2nd-stage relight anomaly. | 100%as of [2]7/7 missions through VA268 Amazon Leo (Apr 30, 2026); Ariane 64 debut Feb 12, 2026 ↑ Best |
| Total flights | 11as of [2]IFT-1 (Apr 2023) through IFT-11 (May 2026 target). IFT-10 (Aug 2025) achieved full mission: booster caught + Ship splash-down. ↑ Best | 8as of [2] | 7as of [2] |
| Cost / kg LEO | ~$600/kgas of [1]SpaceX target figure; not yet achieved in operational configuration ↓ Cheapest | ~$5,500/kgas of [1]Target unit price ¥5B (~$35M at ¥145/$); roughly half H-IIA's per-launch cost | ~$7,500/kgas of [1]Estimate based on ~$115M A62 / ~$165M A64 list prices |
| Summary | Largest and most powerful rocket ever flown. Super Heavy booster uses 33 Raptor engines. V3 Ship introduced Aug 2025. Mechazilla caught the booster on IFT-5 (Oct 2024) and IFT-10 (Aug 2025). Primary vehicle for Artemis HLS lunar landing (Artemis III planned 2026). | Japan's next-generation flagship rocket designed to halve H-IIA costs. Uses three LE-9 engines burning liquid hydrogen — the highest-performing expander-cycle engines in the world. First successful flight was TF2 (Feb 17, 2024). HTV-X1 cargo mission to ISS (Oct 2025) demonstrated operational readiness. | 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. |
