Here are some relevant statements from that article you linked to that support what I have been saying:
...perhaps a strategically publicized test sometime in the future...Right now it is smoke and mirrors. They do not have the 4CI capability to support it. They do not have the OTH or long distance targeting and tracking capability, they do not have the acquisition technology for the seeker head once the missile arrives in the area. And the list goes on.
...the mere perception that China might have an antiship ballistic missile (ASBM) capability could be a game-changer...
While Chinese ASBM capability remains uncertain...
...if supported by "a sophisticated command-and-control system,"
They are looking at it, no doubt, but what they are doing more is getting people all worried about something in the hopes that we will change our direction because we are so far in front of them.
As I said, even if they do come out with something in the future...and in my estimation they are a long ways out from even successfully testing it, much less deploying it...we already have a defense that we have tested successfully and deployed in place to counter it.
