Mainly to "sailorboy"....while I agree with much of what you said, just when did you serve on one? As with the "Sir Galahad", the new Forts had many and various teething problems. They both seem pretty reliable nowadays.
My point is that having "one stop" ships is that flexibility is reduced. If two or more ships are (say) 1000 miles apart and one needs fuel and the other needs missiles...well, the ship can't be in 2 places at once, can it. So, as I said, we need more of them, not less. BY.
