ok, i’ll bite.
If we buy the theory that L.M define supercruise as Mach 1.5,
then it follows that the B-58 hussler cruises at Mach 1.5 on dry thrust, according to L.M.
Now ask yourself: is that reasonable, or just plain rude ?

They defined the term, with respect to the subject at hand, in the previous sentence.
Speed in these studies took the form of supercruise-supersonic flight without using an afterburner (a source of undesirable and unstealthy infrared energy). Optimizing an aircraft for supercruise leads to long, slender configurations with small highly swept wings and large high-temperature engines.
The ATF would not be the first military aircraft capable of supercruising. This title belongs to the B-58 Hustler. The B-58, however, had to employ its afterburners or dive steeply to accelerate through the transonic drag to get to the flight condition where it could supercruise. The F-16XL and newer-model F-16s are capable of supersonic flight without afterburner as well.
Note tha lack of a specific mach 1.5 speed, jsut “supercruise-supersonic flight without using an afterburner”
