Maybe. But the bigger problem is that the forces deploying such a weapon need to exercise and test fire the system at simulated targets -- a lot. That's the only way to take a theoretical capability and make it an operational weapons system that is taken seriously by your adversary. So unless the Chinese start live-fire exercises over the South China Sea demonstrating that they can 'hit' a simulated CVBG, this is all smoke.
Couldn’t help but tail-gate this comment. There was an article day announcing that the Iranian Navy will be deploying a surface combatant into the Atlantic. Talk about blowing smoke! ;-)
