“The H3 Launch Vehicle is a large-size next-generation launch vehicle whose maiden flight is scheduled in Japan Fiscal Year 2020 from the Tanegashima Space Center. H3 is under development to be a successor to the H-IIA Launch Vehicle, the current mainstay launch vehicle, in order to maintain Japan’s autonomous access to space.
Recently, many satellites that are closely related to our lives have been transported to space, thus utilizing space has become part of our daily lives. Under such a progressive society, H3 is aiming to become a launch vehicle that attracts people’s attention not only in Japan but also globally as an easy-to-use space transportation system.
For H3 to succeed, JAXA will modernize the overall launch vehicle based on our experience cultivated through the development and operation of H-IIA. In that sense, we face technological challenges including the development of a new large liquid engine (LE-9) and solid rocket boosters (SRB-3). Technologies developed for H3 will be applied to the Epsilon Launch Vehicle.
JAXA and related companies will make active use of Japanese technologies in various fields to develop the new launch vehicle.”
