A friend of mine doesn't think so, but I don't see how that : plane can fly at Mach 2 without reheat. Your friend is correct. Concorde *is* equipped with Afterburners, but they're used only for brief periods (takeoff and transonic acceleration). The use of Afterburners roughly DOUBLES the specific fuel consumption. Concorde wouldn't have the range to cross the Atlantic if their use were required for cruise.
