yeah, it will have to have refueling if it goes hypersonic, otherwise there is maybe a hour of supersonic flight at mach 5, and definatly a couple of hours going at normal thanssonic or mach 1 speeds.(well, I may be lieing, but it's still pretty big for a fighter jet because of the amount of fuel needed to run the ram jets, which is why there is a pretty big risk(like, 50%) of it falling apart at hypersonic speed unless at high altitude.)
