A carrier can likely get far enough to generate a miss. Missiles and drones have very limited sensors so in order to hit anything another platform has to cue them with a fairly precise target location. In other words, an adversary like China would need to have enough satellites, submarines, and/or patrol aircraft to maintain a continuous target track long enough to make a decision, launch the weapons, and have them fly out to the target. Current thinking is that China could probably do this inside the first island chain but would struggle to put the pieces together further out in the open Pacific Ocean.
