| Summary | 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. | 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). | Currently the most powerful operational rocket in the world. Three Falcon 9 cores sharing propellant cross-feed produce 5.1 MN of sea-level thrust. Primary mission profile: DoD/NRO GEO payloads and planetary science. |
