Developed and built in Japan, the H-II Transfer Vehicle (HTV) known as "KOUNOTORI (white stork)" is an unmanned cargo transfer spacecraft that delivers supplies to the International Space Station (ISS).
Japan, the U.S., and Russia currently operate cargo transfers to the ISS. Among the supply vehicles, KOUNOTORI serves as the backbone of ISS operations with its world-leading supply capacity of approx. 6 metric tons, and is the only space liner capable of delivering large items of hardware.
Given its consistent on-time arrivals ever since the launch of the first technology demonstration mission, KOUNOTORI is widely acknowledged to be a safe and reliable vehicle, for which the world has high expectations regarding its operations.
