See: SBIRS, and missile defense in general. There are also issues with updating the location of carriers, since communications can be jammed and carriers are not stationary. Just being able to know when something is launched (SBIRS) gives the US a defense against these weapons. In addition to that, I would be very surprised if there was not a way to shoot these things down, with lasers or otherwise. We're talking about the US military budget, and maintaining the investment of 50+ billion dollars just spent on building the carriers over the years.
