He said "052D is getting an upgraded CIWS gun..." which could easily just mean that the class itself is being upgraded to 1130 standard. This has already happened to the 054A and as I said, should have happened to the 052D a while ago.
... wait, are you suggesting that all 052Ds will get 1130s?
Because what I was saying is that at this stage we have no indications that all 052Ds will get 1130s. JN hull 9 and onwards were equipped with 1130s while all other JN hulls (and I believe DL hulls atm) were equipped with 730s, and there are no indications of those hulls being upgraded with 1130s.
So the reason I sought to clarify his statement, is because one could mistakenly think he was suggesting all 052Ds will get 1130s to replace 730s, when in reality right now we only know that JN hulls 9 and onwards have had 1130s replacing 730s (fresh out of construction), while all others are remaining with 730s.
