Why would a reentry path differ in our case here from an orbital path?
.
Because it is dynamic and changing -- unlike a stable orbit. Moreover, as the reentering vehicle approaches the outer bounds of the atmosphere it enters a domain of rather large sensitivity of very small changes in its velocity vector as a predictor of its future trajectory. It all makes for an exceedingly difficult intercept problem - particularly given that, unlike orbital rendezvous, it doesn't permit controlled, slow vectoring in the final stages of apoproach.
What objection would you have to the demonstration of a capability we have on about 25 ships that can go anywhere in the world's oceans? Sounds like a good idea to me.
