China is going for 20 heavy carriers and 20 LHD by the 2030s.
Such a force would be ridiculous... it would be much more valuable for them to produce more escort vessels and support vessels and have a more balanced and capable fleet.
They also need to expand their focus beyond the Pacific ocean... they should start reaching out to countries around the world that lack investment and want to grow and develop... in Africa and central and south america and start expanding their trade ties and relationships around the world.
This will be good for China but also for the countries smart enough to improve ties and ignore western bullshit claims that China and Russia are the devil.
They would not gain anything by having 20 heavy carriers, but in terms of cost we would be talking about probably 60 billion dollars just to build them and probably 10 billion a year just to operate them... plus the costs of escorts... a huge drain on the economy for no benefit except dick waving on the internet.
Having some carriers makes a lot of sense because it gives them mobility and more depth in terms of both defence and attack when at sea... but having too many makes less sense.
Give themselves 10 years experience with their current models and they can evaluate what works and is good and what is not so good and worth changing... and they can sell their existing models and build new ships that are more capable and useful for themselves and have a formidable fleet...
