McDonnell-Douglas F-15 Projects

[isayyo2]

Is there any more information available about the proposed about the "big wing" F-15E development proposed by McDonnel Douglas in the mid 1990s? The only immediate reference I can find for it is here.

Snippet view ruins fun but it mentions the speed reduction.

Is it possible that the "big wing" F-15E and the F-15XX mentioned in Post #22 are one in the same?

Ah no I didn’t realize he might have meant that. I was referring to this one.

Flug Revue indicates at thicker wing that reduces top speed from Mach 2.5 to 1.8 and reduces acceleration for the sake of heavier loads on the outet wing pylons. In short, this sounds like the opposite of the supercruise capable F-15XX that was proposed as an ATF alternative a couple years before. On the other hand, I always suspected that leading edge slats, such as on the navalized F-15N or F-15XX would have required a thicker wing, at least outboard where thickness tapers down to 3%!
