The F15A, with a crew of one and the F15B with a crew of two. Since the F15B's primary purpose is aircrew training, I think we can safely assume they scrambled the F15A. The F-15A has a Cruise Speed of 466,79 Mph and a maximum speed of 1649,75 Mph at an altitude of 36007.2 Feet . It's (ferry) range is 1500 miles with three external fuel tanks. Also, the F-15A is capable of aerial refueling . The capability to accelerate to supersonic speed from the F-15A depends on different factors, such as the weight of the aircraft at take off (MTW) and the amount of fuel on board. One would hope that, given one of their primary tasks: the interception of suspicious aircrafts ASAP, the F-15's are always standby in optimal condition and being able to take off within minutes, being able to accelerate to mach 1.5 or faster ASAP and having enough fuel aboard to maintain that speed for a longer period of time.
