The move toward a launch vehicle series will help us reduce costs and provide a wider range of launch capabilities while assuring reliability using the proven technologies acquired through the development of the H-II.
The H2A202 is the H-IIA standard type of this series. Two solid rocket boosters (SRB-A) are equipped. Capable of launching up to four (4) metric tons into Geostationary Transfer Orbit (GTO).
Four solid rocket boosters (SRB-A) are attached. The H2A204 configuration is also capable of launching six (6) metric tons into Geostationary Transfer Orbit (GTO).
In September 2009, H-IIB Test Flight (H-IIB TF1) successfully launched the H-II Transfer Vehicle (HTV) Demonstration Flight into orbit. Customers in the global satellite market from all around the world responded with piqued interest. MHI successfully completed the missions of the H-IIB flight No.2 and No.3, and then we started the launch services of the H-IIB from flight No.4 in 2013. Currently, the HTV is the main payload for the H-IIB launch vehicle Not long into the future, however, we plan to add the H-IIB launch vehicle to our launch service lineup. Until then, we will continue to build experience with our HTV missions. The success of the H-IIB launches will allow us to deliver larger satellites to respond to many of the new needs emerging in the global market.
The H2B is heavier version compared to the current H-IIA launch vehicle. The H-IIB has capability of launching about eight (8) metric tons into Geostationary Transfer Orbit (GTO).
