Developed and built in Japan, the H-II Transfer Vehicle (HTV) known as "KOUNOTORI (meaning 'white stork' in Japanese)" is an unmanned cargo transfer spacecraft that delivers supplies to the International Space Station (ISS).
"KOUNOTORI" provides very basic support for ISS operations by delivering up to six tons of cargo and has the world's largest transportation capacity. It also has the unique function of carrying multiple numbers of large-size experimental instruments on one flight.
