China's military progress has been great and historic. But I think China has only scratched the surface of its full military potential. They are just spending 1.5% of GDP on the military right now. Its lower than most EU countries. I believe when China is truly serious about its military expansion, they will spend 4-5% of GDP on military in peace time. That means atleast 2-3 times bigger quantity of hardware produced.
Let's not even forget what China will be able to do in wartime production levels. China will make US production in WW2 look like Child's play in a future WW3.
There is no need to go anywhere near 4% of China's GDP for military spending, but yes, Chinese wartime production levels would likely look extraordinary, assuming production was uninterrupted.
My guestimate is that mass-produced Chinese nuclear carriers with an airwing would be in the ballpark of $10 Bn. And let's say they commission 1 per year, as a peacetime cold-war scenario.
For another $10 Bn, they could get 5?? Type-095 SSNs every year.
After 10 years, that's 10 nuclear supercarriers plus 50 SSNs.

That's an annual procurement cost of $20 Bn, or about 0.2% of China's GDP.
Of course, you have operating costs as well, but the final figure might only be 0.4%? of GDP after 10 years.
