Are you defending the USN's ability to conduct a 2000 km perimeter CAP or are you suggesting that by 2040 the PLAN CVG would be contracted off to the USN to operate?
If you wish to taken seriously please provide the contents description that support the notion that the USN can conduct a 2000 km perimeter CAP and even if that is true how would that equally apply to the PLAN? Mentioning a link is frankly not good enough.
Then you should read the full CSBA paper which describes the proposed operating profile of future US carriers
Basically, the CSBA are proposing a new airwing with drones to operate CAP at 2000km.
It's certainly possible to construct such an airwing, but most of the aircraft envisioned currently do not exist.
Given the aircraft we've seen so far plus a military budget which would be larger than the US circa 2030-2035, it should be feasible for the Chinese carrier programme to field an equivalent airwing in the future.
