They're about to commission their third.

With nuclear-powered ones on the way.

They're looking at building 4-6 additional carriers, which they would have operating in the one region.

America's carriers are thinly scattered around the world.

I guess the point is that China would have a numerical advantage if the war was fought in the South China Sea.

But I think it comes down to who deploys hypersonic missiles in great enough numbers first.

Aircraft carriers have zero defence against hypersonics. At least for now.
