Initially seven missions were planned between 2008–2015. With the extension of the ISS project through 2028, three more missions were added, with the tenth flight planned to debut an improved, cost-reduced version called the [[HTV-X]].<ref name="mext20150520">{{cite web|url=http://www.mext.go.jp/b_menu/shingi/gijyutu/gijyutu2/071/shiryo/__icsFiles/afieldfile/2015/05/28/1358152_1.pdf|script-title=ja:2016年～2020年のISS共通システム運用経費（次期CSOC）の我が国の負担方法の在り方について|publisher=Research and Development Division, Ministry of Education, Culture, Sports, Science and Technology|date=May 20, 2015|access-date=June 4, 2015|url-status=live|archive-url=https://web.archive.org/web/20150605155155/http://www.mext.go.jp/b_menu/shingi/gijyutu/gijyutu2/071/shiryo/__icsFiles/afieldfile/2015/05/28/1358152_1.pdf|archive-date=June 5, 2015}}</ref>

The first vehicle was launched on an [[H-IIB]] rocket, a more powerful version of the earlier [[H-IIA]], at 17:01 UTC on 10 September 2009, from Launch Pad 2 of the [[Yoshinobu Launch Complex]] at the [[Tanegashima Space Center]].<ref>{{cite press release|url=http://www.jaxa.jp/press/2009/07/20090708_h2b_e.html|title=Launch of the H-IIB Launch Vehicle Test Flight |archive-url=https://web.archive.org/web/20090711101704/http://www.jaxa.jp/press/2009/07/20090708_h2b_e.html|archive-date=11 July 2009|work=[[JAXA]]|date=8 July 2009|access-date=20 June 2019}}</ref>

By May 2020, all nine missions planned for HTV had been successfully launched, and the spacecraft was retired.

The improved HTV-X is planned to be first used for the tenth flight and will perform scheduled ISS resupply duties starting in 2025.<ref>{{Cite web|url=https://spacenews.com/jaxa-astronaut-charts-future/|title=Koichi Wakata, JAXA vice president and astronaut, helps chart future of ISS and human space exploration|date=27 July 2018|website=SpaceNews}}</ref>
