Yes, HiMAT was particularly good in the transonic range: .8 to 1.2 mach. I have no idea how good it was beyond that speed. Still, it would kick butt on the F-35 or anything current.
Now, the F-14 with the wing glove vanes was capable of pulling 7G at mach 2+. Of course the Navy deleted them for the B and D. Ignorant, short sighted thinking to say the least.
Of course, the US military decided that supersonic combat was irrelevant in the late 80's to the present. They decided that electronics were more important than anything else. Ignorance is bliss.
