How is that special? The military already has the F-22 which can supercruise just fine. Or the Eurofighter if your military isn’t the USAF.
And also, fuel cost is probably the last concern of an Air Force. Maybe logistics of supplying fuel in an actual war is important, but I think the money for buying the fuel itself is basically zero compared to maintenance and getting the plane in the first place.
