I've no doubt the Chinese will build an extensive fleet of carriers. I can't picture the Russians doing the same. Time will tell.
I have no doubt either, but that was not the point you initially made, which was that Russia are only currently making frigates, and this:
But I think where we differ fundamentally is on the idea that there is a future for Russian carrier aviation.
They don't have to match China nor the US.
They have never stated they would.
It doesn't mean they won't operate a carrier or two or three, or whatever.
All evidence suggests a reinvestment into shipyards, and a slow but steady growth in the size of naval ships being constructed.
And an interest in keeping the Kuznetsov, and maintaining a fixed shipboard air component.
They built an onshore carrier aviation training facility in Yeysk, and are back at the NITKA carrier aviation training complex in Crimea. Kuznetsovs airwing have done training there since then.
The rest, the future, we can take educated guesses on, based on what is happening.
