You forgot just one tiny little detail
US ships currently don't have anti-ship missiles for those VLS , so they would have to relay on old Harpoon launchers (removed from some ships) . On the other hand, Chinese could and would pack ASMs in their VLS. Therefore, in case of conflict, Chinese ships would have an advantage until LRASM arrives .
I deliberately didn't calculate in air power , because we have been comparing surface combatants . In case of war, both sides would try to avoid areas where enemy air units could strike them, but that is another story .
Nothing has been forgotten.
None of the Type 052C can carry a ASMs in their VLS.
The US Navy Tactical Tomahawk IV has a two-way data link which allows the missiles to be retargeted on the fly, and includes a TV camera with real time video feed, and cooperative engagement capabilities, being able to accept target data from multiple sources. They could be used for anti-shipping missions as they stand. In addition, a 2015 upgrade plans to add radar receivers to the missiles as well, for additional targeting capabilities.
Tactical Tomahak missiles have been in full rate production for several years.
The US and its allies would also work together in any major conflict involving any of them. They exercise regularly for cooperative engagement and any of the three Korean AEGIS vessel with their 16 ASMs and more VLS cruise missiles, or the six JMSDF, with their eight ASMs each would be a part of any Surface Action Group, or Carrier Strike Group with US vessels.
With the Tactical Tomahak capabilities, the Tico ASMs, the Burke flight I and II ASMs, and all of those allied ASMs, their would be overwhelming force available. Now and for the foreseeable future.
Finally, you simply cannot set aside either of the probabe two US carriers working with these ships either. In any major conflict, the principe role of those AEGIS vessels would be to protect the carriers, who would sweep the sea of enemy surface combatants with their aie wing.
As I say, the PLAN is doing amazing things. But the reality is that in any major conflict that pulls in the US they would have to face the US, Japan, and probably South Korea. They are a long wys from being able to do that...and this does not even include the huge disparity of SSNs that the US would apply in such an event.
The PLAN has excellent AEGIS-like vessels, and will build many more. The eventual 18 Type 052C/D vessels, and probable 10-12 Type 055 vessels will be a critical and powerful force in the western Pacific. They will be modern, and very capable.
But, without large numbers of equally capable SSNs and 2-3 available carriers and their air wings, they would be overwhelmed.
It will be the late 2020s and into the 2030s, IMHO before the PLAN has successfully integrated and worked up all of those forces to prevent that from happening.
And the US and its allies will themselves not be static in the mean time.
Time will tell, and the naval technology development in the mean time will be very exciting and interesting to watch develop.
