Not exact, but the key concept: the central line landing is a possibility.

That's not a valid reasoning.

For starters, the USS United States has a flushed deck design, meaning that she was not designed with any permanent island superstructure. However, the 076 LHD does have island superstructure (two of them, in fact). That alone nullifies any notion of a landing strip with its central line lined along the centerline of the warship, as the landing strip had to be aligned off the centerline of the warship in the direction away from the island superstructures in order to avoid warplanes from clipping their wings onto the island superstructures during landing.

And if you are talking about a straight deck flight deck - Such designs have existed all the way back in the 1920s, i.e. when the world's first ever CV hit the water. There's nothing new about it.

For example

Suppose, let's imagine, that the satellite network (or precisely some Drones) detects a threat on an island in the first chain.

Who is in charge

GJ-11 taking off from 076

While the large aircraft carrier Fujian and Destroyers 055 are in charge of dominating the Ocean.

There is no such requirement. The front part of the deck was used for parking and launch at the straight deck design. Failing to catch the arresting cable could result in a crash on the front deck.

Central line landing is an easier approach for landing. Of course, the wing span needs to be limited, with 25 wide runway for a maximum 15m wide jet, or 18m wide for a low-speed drone. PLAN already has a central line landing ship built to experiment.

So I suppose that warplanes landing on the flight decks of aircraft carriers since the interwar period just clipped their wings against the island superstructures?

I don't think you realize just how massive the wingspans of UCAVs of substantial sizes and capabilities can be - And why they are designed as such in the first place.

In fact, this applies to literally every carrier-based aircraft that have ever existed.

And here're the dimensions of the ship itself.

Sorry to disappoint, but 16.5 meters is nowhere near being enough to conduct your so-called "centerline landing" while having simultaneous takeoff operations on the exact same flight deck towards the front. And we haven't even talked about the length of the flight deck itself, which even the Mojave STOL-capable UAV would struggle very hard to land without going over the bow and into the water.

In fact, nobody around the world does that. And there are plenty of good reasons why nobody chooses the flight deck layout design of the cancelled USS United States CV.

Therefore, warship designers are left with two choices - Either the aircraft carriers have angled deck designs to enable simultaneous landing and launching operations (i.e. by directing the landing warplane at a sufficient angle away from other warplanes that are parked/being launched towards the front of the flight deck), or they must accept having only one of the two operations undertaken at any given time with a straight deck design.
