| Summary | Japan's flagship medium-lift rocket for 24 years, retiring after an exceptional 49/50 mission success record. Launched the SELENE lunar orbiter (2007), Akatsuki Venus probe (2010), Hayabusa2 (2014), SLIM lunar lander (2023), and the ALOS series Earth observation satellites. | Largest and most powerful rocket ever flown. Super Heavy booster uses 33 Raptor engines. V3 Ship debuted on Flight 12 (May 22, 2026) from Starbase Pad 2 — it reached space but broke up at the ocean surface, and the vehicle is grounded pending an FAA mishap review. Mechazilla booster catches demonstrated from Flight 5 (Oct 2024) onward; first payload deploy on Flight 10 (Aug 2025). Primary vehicle for the Artemis HLS lunar lander (Artemis III LEO docking demo 2027, first landing on Artemis IV). | LandSpace's enhanced methalox launcher, the higher-performance successor to the original Zhuque-2 (the first methalox rocket ever to reach orbit, in 2023) — see slug 'zhuque-2' for the original vehicle already in our database. |
