Why does the 'sub' have to know 'where' the helicopter is ? All the sub has to do is launch it. The missile (presumably) contains guidance and homing abilities and can 'find' the target itself. This type of 'missile' has been mentioned and discussed throughout the posts on this thread.

So the sub just shoots it off and hopes for the best? Do you mind if I ask what your experience on this subject is?

Let me ask you this. Does the Navy have 'command and control' systems that allow one SHIP to fire a missile and the 'control' or guidance to target to come from another ship, or an aircraft (like an AWACS) ?

IIRC, that is part of the way an AEGIS system works.
