| 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 commercially active small launch vehicle, designed and built in-house at Rocket Lab. Rutherford engines are the first flight-proven engines made with additive manufacturing (metal 3D printing). Booster recovery via parachute and helicopter catch (later transitioned to ocean recovery). |
