IOTL, specialized anti-aircraft ships often carry names and classifications similar to those of other ships their size.
Your challenge is to come up with a term or set of terms, preferably along with a two-digit hull code for the USN not already used by 1941 (see the "designation" column here: http://www.ibiblio.org/hyperwar/USN/USN-ships.html ), for specialized anti-aircraft ships such as the USN's Atlanta class.
Said term(s) would eventually be used for ships such as the Ticonderoga and Arleigh Burke classes.
