re: PLAN Type 052 Class Destroyer
Sorry but no navy in the world wants to disrupt sea lines of comunication.
Come on, surely you not not naive enough to believe that? In the event of war, every navy would want to cut the sea based supply lines of their enemies.
Only the USN can do it, and the USN has had freedom of navigation for every nation as one of its core interests for decades. They wont allow any navy to block sea lines of comunication. All merchant navies can count on them, including china. There is no need for china to do that.
Again, I'm not sure if this is naivety or wishful thinking. The US will not insert itself into a fight between a non-aligned power and a potential rival. Just for example, if a war broke out between China and India and India decided to go after Chinese shipping in the Indian Ocean, are you saying the USN will sink the Indian fleet because of it? Of course not, and if the roles were reversed, there would be no way America would leave itself vulnerable by not developing a strong navy if China promised to keep the world's shipping lanes open.
For PLAN to truly protect china´s sea lines, it would have to increase imensely its size.
Which is precisely what the PLAN has been doing in the last decade.
To defend against japan/SK navies (which also includes taking the fighting to the high seas), china will need all vessels that it can get. Thats why ESF should be the priority.
You do realize that just because a ship is assigned to the SSF or NSF it would not forbid them to operate in the ESF area of jurisdiction right?
The idea that SK or Japan would try to launch some invasion of the Chinese eastern seaboard is laughable. They haven't got anywhere near the kind of strength. Even fighting on the 'high seas' within the second island chain, the ESF would be under land based sensor and air cover. PLAAF and PLANAF land based strike power alone is more than enough to make sure the Japanese and SK surface fleets cannot operate safely within 500-1000km of the Chinese coast quite easily. Anything beyond that is of little concern to the PLA toh. If the Japanese and SK navies want to intercept shipping going to and from America carrying the vast amounts of daily items that most Americans depend on, well, lets just say that is as much of a blockade against China as it is against America, and when its national interests are directly threatened is the only time you can realiably expect the USN to step in.
