Major Chinese/Pacific Carrier deployments

 Recent satellite images of Hainan show major new assets for the Chinese Navy, including the Supercarrier Shandong 17

 and the Amphibious Assault Carrier Hainan 31

Note these ships are deployed with the Chinese South Sea Fleet, which is within striking distance of Taiwan with overwhelming force.  While the Hainan 31 has a practical use against Taiwan, the Shandong 17 does not, only to provide overwhelming Chinese air cover.  It does have a practical use against american and Japanese Carrier groups.
​Excellent examples of these can be found at Yokosuka, most notably the USS Ronald Reagan CVN-76

Additionally, because of the Chinese military buildup, Japan has built it's own Carriers, starting with the JS Izumo DDH-183

The Izumo, along with it's sister ship JS Kaga DDH-184, deploys F-35 fighters.  In all probability the Chinese Supercarrier deployments are not to attack Taiwan directly, but to confront american Supercarriers, which they are the equal of.
