ElwoodBlues According to the US Navy, what actually makes an aircraft carrier obsolete today is that it can be sunk in a heartbeat by a single ballistic missile.
In addition to it's vulnerability in that regard, an aircraft carrier cannot defend itself on any level, which is why they are always escorted by a small armada of US Navy Destroyers which act as the 'guns and cannons' an aircraft carrier is not otherwise fitted with.
Therefore, to own an aircraft carrier also means owning about 5 destroyers which act as permanent escort vessels which play defense for that one floating airport, which is all an aircraft carrier really is. This means that carrier groups are obsolete
permanently according to US Navy sources.
