宇宙ステーション補給機
H-IIB was able to carry a payload of up to to Geostationary transfer orbit (GTO), compared with the payload of 4000-6000 kg for the H-IIA, a predecessor design. Its performance to low Earth orbit (LEO) was sufficient for the H-II Transfer Vehicle (HTV). The first H-IIB was launched in September 2009 and the last H-IIB was launched in May 2020.
