Yeah, this is true. I hadn't really thought of that. I guess it would depend on what sort of mission profile and the type of target one wanted to neutralize. Perhaps, if one wanted to go for an all-out kinetic kill profile then, yes. Why slow down?
But just for argument's sake, your mission profile called for releasing X-amount of cruise missiles into a heavily defended airspace no manned aircraft could enter. Instead of wholesale kinetic kill tactics, maybe you only want to remove certain key targets in your designated target area. Kinetic kill is definitely great. But suppose the mission called for the sort of precision only a subsonic cruise missile would ensure? Perhaps then, would the cruise missiles be necessary. But then again........
Perhaps, you could drop two CAV's, kinda of a one-on-one approach. One CAV loaded up with cruise missiles for you precision work. And the other CAV for a kinetic kill approach, a la " Rods Of God" or some other amazing toy. Either way, it's going to be a really bad day for whoever's on the recieving end.
The upshot: you won't have to send your aircrews to their death over an impenatrable airspace. They will fight another day and all the resources to needed for a strike package (e.g.- tankers, AWACS, ECM, SAR helos, etc.) won't be neddlessly wasted on that one set of targets. And all the while your targets will still be neutralized. Things to definbitely make you "Hmmm"
OK, I know I'm going get dissected now
