The idea that the USN would seek to build a larger carrier just so it is longer than 003 out of spite is a bit silly.Actually, i think that it does matter. I think that the US prizes aircraft carriers a lot. Its a kind of national status. For example, an attack on the carriers is considered an attack on CONUS.
Not that i think that it will be longer, but if china was to make an aircraft carrier longer than any ship of the USN, even if it is conventional and with less displacement, there would be offended egos on the other side of the pacific. And more calls to make bigger ships and navy.
Would that make any difference to china if it happened, i dont think so.
This is verging on OT here but I will just note the French very much disagree that CdG is "clearly enough", their next carrier will be rather similarly sized to Type 003, currently estimated at 75k tons+. There is no such thing as a carrier that is "too large" as far as deck and hangar space is concerned. The only limiting factors are berthing/docking capacity and the need to transfer through certain areas (Suez). The fact of the matter is pretty much all carrier navies would love to have something sized like a supercarrier, its a simple matter of cost which limits such pursuits.To be honest I think the Nimitz class is just too large for most uses.
I think something with the displacement of the Charles de Gaulle is clearly enough and at best something with the displacement of the Shandong would be quite enough....
It is true for everything.The fact of the matter is pretty much all carrier navies would love to have something sized like a supercarrier, its a simple matter of cost which limits such pursuits.
