The PLAN DF-21C anti-ship Ballistic Missile was confirmed by the USN earlier this year. They are apparently developing plans with their SM-3s to defend against it. Please read the link to the U.S Navy announcement on the reference that I cited earlier.
If you feel that you are correct and that the USN intelligence is wrong then that is your business.
What does US-intelligence say about Chinese DEPLOYMENTS in the Indian Ocean???? I’m still waiting to hear a word from you on that.
The DF-21 wonder weapon is obviously a threat but the not kind of silver bullet you are drumming it be based on some Chicom fanboy sites.
