Wow! Japan has to be just as concerned as Taiwan - and the Chinese hate Japan.
*** "The ocean is notoriously shallow along the south-eastern coast of China. I told you that the waters surrounding China are only conducive to CCP naval movements twice a year: April-ish and November-ish..." ***
Excellent information and good intel on the names and types of all the Chinese naval vessels.
Is the navy essential to China in regards to taking control of Taiwan? ...of Japan?
The prevailing current through the strait is a branch of the Kuroshio, or Japan, Current which is the western Pacific equivalent of the Gulf Stream. There is a small southward flowing current close in on the coast of mainland China. Prevailing winds are from the Northeast, especially in winter. In other words, the Taiwan Strait is a choppy mess of a place to navigate much less fight.
Add to that the fact that it is so narrow, almost all of the strait is within coastal missile range of one side or the other and much of it is within artillery range. You may as well try to fight a naval battle on Lake Erie with modern weapons. No thank you.
Given that the average PLA soldier is too short to wade and can't yet fly under their own power, then I would say yes, the PLAN is essential to the CCP attacking Taiwan or Japan.
