AWACS detect 4th generation jet(with weapon) in 300-400 km. AWACS detect jet in 70-150 km, depends on angle of the jet.
Unlike land base radar network, naval radar network is very limited. In stealthy era, AWACS detection range is not enough at all. Carrier air defense heavily depends on jet patrolling, much more than 4th generation era. This is huge difference.
What is even worse, you need 2 jets patrolling in every directions, so that 2 jet's electro-optical system manage a mini network for angle/distance measurement.
In 4th generation era, AWACS is deployed forward. So that threat can be mitigated. In 5th generation era, it's not.
In 4th generation era, one jet can cover 1-2 directions. In 5th generation era, you need 500 km air defense, 2 jets can cover 1 direction only.
In 2000s, AAM is about 50-75km. Now it's 160 km. Future it will be longer and longer.
The stress of carrier air defense is much heavier than before. You need at least 2-3 times jets for CAP only, and CAP is 24*7.
Once you get into the details of real operation, you will know what China carrier need.
