What seems obvious to us is eye opening for the "expert OSINT" twitter crowd. I see this as Lyle warning the experts who think China is going to do the 1million men across the straits maneuvers which US military can counter by flying over unopposed (I know, but that's what people).
They are also shocked to find out China has enough ground attack capabilities to knock out all of Taiwan's air defense and Ryuku bases. Or that China has a large MPA fleet.
Each fleet they show in there would probably suffice as a CSG on long deployment. But it wouldn't work like that in reality.
Realistically, if they had 3 carriers in service, they can at most surge 2 carriers in operation. They'd probably put the more capable carrier east of Taiwan and the less capable in SCS. The escorts will depend on which surface combatants are available, but I would imagine they need at 4 055s (and more if they have more than 8 in service), 1 075, 10 052C/Ds, 10 054As, half of their active 093s/Yuan. I'd expect an airwing of 24 to 30 J-35s, about 15 J-15/Ds + 4 KJ-600 and 6 to 10 helicopters for CV-18 in wartime. And it's proximity to China means they can swap out aircraft if it needs heavy maintenance, so they can keep up high availability among on board aircraft. It will also be so close to mainland that replenishment is never an issue.
