The H-IIB Launch Vehicle is an powerful version of H-IIA to open the door to a new possibility for future missions including cargo transport to the International Space Station (ISS). The major purpose of H-IIB is to launch the H-II Transfer Vehicle "KOUNOTORII" (HTV), a cargo transporter, to the ISS. The KOUNOTORI carries necessary daily ...

For this reason, the launch capacity of the H-IIB was set at 16.5 tons. To achieve this, H-IIB use two first-stage H-IIA engines (LE-7A), which are clustered and loaded with 1.7 times more propellant than on the H-IIA. To achieve this improvement, the diameter of the first-stage body has been expanded to 5.2 meters from the H-IIA's 4 meters.

2020年5月21日 · The H-IIB Launch Vehicle No. 4 (H-IIB F4) carrying the H-II Transfer Vehicle (HTV4, a cargo transporter to the International Space Station) will be launched on August 4 (Sunday, Japan Standard Time.) The launch time will be around 4:48 a.m. (JST.) It will be blasted off from the Yoshinobu Launch Complex at the Tanegahsima Space Center.

The major purpose of H-IIB is to launch the H-II Transfer Vehicle "KOUNOTORI" (HTV), a cargo transporter, to the ISS. The KOUNOTORI carries necessary daily commodities for the crew astronauts, spare parts for the ISS, experimental devices and samples, and other research items. By operating two launch vehicles, H-IIA and H-IIB, we can respond to ...

The KOUNOTORI is an unmanned cargo transporter to be launched by the H-IIB launch vehicle.It is designed to deliver up to six tons of supplies including food, clothes, and experiment devices to the ISS in orbit at an altitude of about 400 kilometers and return with spent equipment, used clothing, and other waste material.

The H-IIB project is the first rocket developed jointly by JAXA and MHI. All previous projects had been fully JAXA's responsibility. This time JAXA is in charge of preliminary design, readiness of the ground facility, and the development new technologies in which the private sector has limited competencies, while the private sector is ...

The H-IIB Launch Vehicle is equipped with four Solid Rocket Boosters (SRB-As) whereas only two SRB-As are attached to the standard H-IIA. The H-IIA Launch Vehicle No 11 with four SRB-As (H2A204 type) was successfully launched in 2006, thus we utilized already verified technology in the H-IIB to improve its launch capability.

The H-IIB Launch Vehicle No. 3 (H-IIB F3) is scheduled to be launched on July 21 (Sat.,) 2012 to inject its payload, the third H-II Transfer Vehicle (HTV3) into its orbit. The H-IIB Test Flight was launched exactly at the scheduled launch time and date on September 11, 2009, and that was the first punctual launch of the first flight of Japan ...
