HTV-X1 is the first flight of the HTV-X series, serving as a technical demonstration mission of the new uncrewed expendable cargo spacecraft. As the maiden flight, HTV-X1 is flown as a technical demonstration and was thus not loaded to maximum capacity, with a deficit of approximately 1,500 kilograms (3,300 lb) deducted mainly from unpressurised cargo. HTV-X1 is scheduled to remain berthed to the ISS for up to six months, during which cargo will be transferred to the ISS and waste loaded onto the HTV-X.
