US CIWS is only 20mm which is effective against regular sized, subsonic anti-ship missiles. But what about the Brahmos? It's huge and supersonic. It will not be stopped by the 20mm which will mean that even after a successful hit, the debris will be kinetic enough and have enough mass to damage the ship.
Now, Turkey has a weapon which is a copy of the millenium gun, something like 35mm, if memory serves me right. It has the mass and kinetics to stop a supersonic heavy missile much better. If this can be coupled with a Turkic close-in SAM, you have a winner.
Problem with Chinese equipment, now they are exhorbitantly priced, often unreliable operationally.
If only Pak would develop its own SAM systems. PN, PA and PAF could have all benefited.
