H3 Launch Vehicle

The H3 Launch Vehicle is an innovated version of H-ⅡA and H-ⅡB, currently Japan's primary launch vehicles, and succeeds in significantly reducing launching costs as well as improving versatility. The new launch vehicle aims to take care of Japan's space transportation from the 2020s onwards and make full-scale entry into the international satellite launching market. We began development in FY2014 with the aim of the first launch in FY2020. We engage in development of a new solid booster (SRB-3), etc. together with the JAXA and the prime contractor, Mitsubishi Heavy Industries.
