| Summary | Rocket Lab's medium-lift reusable rocket targeting the $100B constellation replenishment market. Uses a 'hungry hippo' fairings design that opens at the top rather than traditional clamshell separation. First flight delayed to Q4 2026 after a Jan 2026 propellant tank test anomaly. | 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. | 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. |
