I don't keep abreast this any longer. Last time I checked, they were so far off that it wasn't anything more than a dream of those who don't know better. We don't have to get our a/c carriers in range of their coast to defend Taiwan with our Naval a/c. If they attack our Navy with their Navy, they'll completely lose theirs, even if it's 10 times its present size. So we'll likely own the air around Taiwan, not to mention our subs disrupting the seas. Even if China had the equipment, that's less than half the battle. China has zero experience at an operation this size, and next to zero chance of getting it right on first try.
China's ambitions toward Taiwan is something we need to be prepared for and continue to counter wo that they can't intimidate Taiwan into submission, not something we need to be fearful of occurring while we're not looking.
