| 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. | Firefly Aerospace's two-stage small-lift rocket powered by four Reaver engines at sea level and one Lightning engine in vacuum. Also provides launch services for NASA's CLPS programme (Blue Ghost lander launched on Falcon 9). FLTA007 'Stairway to Seven' succeeded Mar 11, 2026. | India's most reliable and frequently flown launch vehicle, operational since 1994. Set a world record in Feb 2017 by deploying 104 satellites in a single flight (Cartosat-2D + 103 microsats). Launched Chandrayaan-1 (2008), Mars Orbiter Mission (2013), and Aditya-L1 (2023). The dual C61/C62 failure streak raised concerns about aging solid motor design. |
