Congratulations to China on their latest and greatest-ever Carrier. A phenomenal achievement indeed.
That said, it is necessary for some posters here to be humble and not try to act as if the Americans have been making stupid design decisions for their Carriers and that China has built a perfect Carrier on its very first attempt.
For example, a couple of posters have said that Americans designing additional lifts on the port side is unnecessary ("US has an odd obsession with having a lift on port side") without realizing that it is for redundancy against wartime damage to the starboard elevators. Also, having an elevator that allows for planes to also exit the port side of the hangar greatly facilitates (you do not have to turn the parked aircraft's nose to the other side) aircraft flow when more aircrafts are needed on the deck and in quick succession. You cannot design a Carrier assuming that it won't be hit during wartime.
Also, catapult failture rates are greater than what is acknowledged. Even on a 4 catapult American Carrier, to keep 3 working at all times is a huge ask. In Fujian's case, PLAN would be lucky to have 2 working at all times during wartime when intense cyclic launches would be required.
So, while Fujian is a fantastic achievement by any standard, it is still the penultimate step for PLAN towards a true 4-catapult, 3/4 lift, 75 aircraft air-wing nuclear-powered Supercarrier.
