Construct all the ships you want, but where do you get the sailors for them afterwards? As it is now, we have naval superiority, and can achieve air superiority from carriers and land-based aviation around Taiwan right now.
Given help from the Japanese, South Koreans, Aussies and especially the Indians, the Chinese would never get so much as a fishing junk out on the open oceans anywhere around West or Southeast Asia, if hostilities erupted.
What we need is not new construction, although a few new DD(X)'s and some new attack subs would be especially welcome.

As I understand it, the next generation of Navy ships will require next to 0 sailors, proportionally compared to current ships.
