There's no doubt this thing can be defeated, but what I'm saying is that it just makes the the commander's job that much harder. For example, when launching or retrieving aircraft, he has to turn his Phalanx-type weps off. Also, there are times when his course is predictable, like when he turns into the wind to launch or retrieve aircraft, or when he has to suspend air ops and maneuver to avoid shallow water. A smart enemy will mix his threats, too, say launching a sizzler type weapon and simultaneously an airstrike and perhaps a fast missile boat attack. He will use feints and deception. The American commander will also have to go farther out than normal into safer waters whenever he has to refuel or undergo replenishment (even nuke carriers need jet fuel for their planes and bunker fuel for their escorts). This will mean spending more time getting to and from station. Even the supply and escort vessels will have to modify their normal procedures, because they are vulnerable to these things too. They are as important as the combatants to the operation and they are very poorly armed and defended. Like they say, amateurs talk tactics, professionals talk logistics.

I was involved in a big NATO exercise like this (granted it was a long time ago and the technology and tactical situation was very different, and our opponents were very good) where we were pretending to invade Norway and the Russians were pretending to defend it. We had a hundred ships spread out over an area about the size of Texas, and our fleet and theirs were groping around blind in some of the worst weather the sea can throw at you. In spite of our radio silence and our low electronic profile (you can't sneak up on anyone if you're using your radar, but without it you're in the 19th century, communicating with flags and lights and scanning the horizion with binoculars.) By the time we were south of Iceland the Russian Bison and Bear patrols had found us, and 48 hours later they were shadowing us with a couple of frigates. If it had been for real, we would have punched through their defense, but we would have taken casualties and the element of surprise would have been lost.

I guess the point I'm tryng to make is that it isn't just about technology,
just like it isn't that way for the grunt on the ground either. Experience has shown us that when the balloon goes up, nothing works the way it's supposed to, especially if neither side has fought a real war in a long time. That's why things go wrong, it's always the little detail you overlooked during planning that gets you, not some quantum advantage or shortcoming in technology.
