Did it ever occur to you that if the same job can be done by a less expensive asset then you can also purchase more of them? Instead of two ships of limited usefulness you might have 5 or 10 that are as effective and far more flexible? Of course it didn't.
Did it ever occur to you that using your existing stock of usable hulls is a cheaper proposition than buying new ones from Litton until you're broke?
Put another way, did you ever hear of getting full value from your already-amortized investments?
Taking your logic a little further, perhaps you'd like to try to do the job with a mighty fleet of highly flexible Boston whalers equipped with RPG's -- the way the Iranian Revolutionary Guards were doing it, back before "Robocruiser" cleaned their clock.
That's the rowboat Navy of the future the "on-the-cheap" thinking in the White House and Pentagon is lusting to buy us, in lieu of all those horridly expensive real ships manned by hundreds of real men.
The Navy of the future will be an AI Navy, contracted out to chipmaking companies on Taiwan, right? If we do it your way, that is.
