| 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. | The world's most frequently flown orbital rocket. Block 5 first stages have landed over 280 times and reflown up to 23 times. Backbone of Starlink and commercial crewed launches. | Blue Origin's first orbital rocket. The 7-meter payload fairing is the widest of any current production rocket. NG-2 (Nov 2025) achieved the company's first booster landing on drone ship Jacklyn. |
