Every CCP sub would be siting around the island as a defensive perimeter for any logistical support, which must be brought from thousands of miles away and months to fully mobilize.
Taiwan has nothing but basically F-16's, older ADF versions at that, but probably upgraded indigenously. Runways would be cratered. The Electrical grid knocked out. Support would have to come in initially against a CCP air umbrella.
Brute force, shipping capability of the CCP, 90 miles away, 1.3B people and the second or first economy in the world on how you want to look at it..
And the last place I would want to be is on a USN carrier. Counter missile tech would have to approach 100% PK or you are disabled, at the least.
Subs and stealth are the way of the future and smaller dispersed nodes of firepower.
JMO..lets hope we never find out.
