I’ll grant you the continued efforts of the submarine folks (silent service and all) but the rest…come on. The first DDGX won’t feel the kiss of a champagne bottle for another 10 years and I can’t even imagine how long it will take any new amphibs to get on line. You are right to note that the carrier has worked for us consistently over the last 80 years…just as the battleship/dreadnaught worked for us for the previous 80.And yet we're in the midst of recapitalizing our sub force, our DDGs and investing in a whole new class of FFGs. We spend our defense dollars on CVNs because they have adapted well to a variety of missions short of peer conflict, while being the best means of power projection available during those high end fights. It's not an addiction... it is what has worked for us consistently over the last 80 years.
Or…as the 1930’s quote goes…”You may hear people say that submarines have done away with the battleship, and that aircraft have annulled the mastery of the sea. That is what our pessimists say. But do you imagine that the clumsy submarine or the fragile aeroplane is really the last word of science?” I’d dare say that the CVN may well find itself far from being the last word of science.
