If your world is USN centric then the differentiation is irrelevant because all the carriers come with CAT. However outside of the USN, the distinction is useful in any conversation because there is a clear divide between the two. As for the PLAN which is the nature of this thread, we expect the migration to CAT will eventually happen but until then a lot of the conversation will revolve around this.
Yes, that's why I was specific in my explanation.
Anyway I think that was what my shipmate Popeye was alluding to.
