Okay, so when Skunk Works and Kelly and Ben Rich and everybody sit down to work on this, the current state-of-the-art fastest plane at the time, this is late 1950s when they start working on this, is the McDonnell Douglas F-4 Phantom. which is able to hit just over Mach 2 with its afterburners on. So not sustained flight, like when you punch the afterburners, it can barely touch Mach 2.
