<!---->H-IIB (H2B) is an expendable launch system used to launch H-II Transfer Vehicles (HTV) towards the International Space Station. H-IIB rockets are liquid-fuelled with solid-fuel strap-on boosters and are launched from the Tanegashima Space Center in Japan. Mitsubishi and JAXA have been primarily responsible for design, manufacture, and operation of H-IIB.

H-IIB is able to carry a payload of up to 8 tons to GTO, compared with the payload of 4 to 6 tons for the H-IIA. Its performance to LEO is sufficient for the HTV (16,500&nbsp;kg). The first H-IIB was launched in September 2009.


The H-IIB launch vehicle is a launch vehicle developed jointly by JAXA and Mitsubishi Heavy Industries to launch the H-II Transfer Vehicle. The H-IIB was designed to adopt methods and components that have already been verified by flights on the H-IIA, so that manufacturing the new launch vehicle would be more cost-effective, with less risk, in a shorter period of time. JAXA was in charge of preliminary design, readiness of the ground facility, and the development of new technologies for the H-IIB, in which the private sector has limited competencies, while the Mitsubishi Heavy Industries is responsible for manufacturing. JAXA successfully conducted eight firing tests of the new cluster design with the simulated first-stage propulsion system, called Battleship Firing Tests, since March 2008, at MHI's Tashiro Test Facility in Odate, Akita...
