I thought you were a submarine guy?

I imagine that fuel cost was a factor over packaging concerns on that project. Or perhaps an aircraft which spends a lot of time in the transitional speeds between subsonic and supersonic speeds.

On boats and hovercraft there is "getting over the hump (hump speed)" transition from displacement mode to planing or hover mode. It would be of interest to me to find out if there is a similar Whitcomb Rule/Area Rule for these types of watercraft. Thinking perhaps narrow bow and wide stern so the front pops up with the rear to follow. Triangular not rectangular footprint.

This reduction of area is mainly intended when these airplanes fly at transonic speeds (0.8-1.2) but not when flying at supersonic speeds where a front shock wave is created.
