I should note that max speed (supersonic) is very much *not* max cruise. The maximum range is severely decreased by flying at supersonic speeds because it is highly fuel-inefficient. Instead, the speed for max cruise (farthest distance traveled per pound of fuel used) is typically around Mach 0.8-0.9 for modern fighters; the fighter would be traveling at around that speed to go the farthest on a single tank of gas.
