Minor nitpick: I'm pretty sure you mean the F-15, not the F14.  As for
the F-15, yes the most recent version with GE powerplants can indeed
supercruise. I'm not sure about the B-1 Lancer either- I don't *think*
it can actually supercruise, but one of the B-1 tactics to evade
pursuing fighters is to stay supersonic (at treetop altitudes, BTW)
until the fighters run out of fuel trying to keep up.  That capabiltiy
is probably simply because it has a lot more fuel reserve than a fighter
