6 052Cs or 3 051/052Bs load 48 missiles, not 64.One Type 052C is not going to down 64 missiles coming at it.
You have to figure that they will be firing two missiles at each anti-shipping missile to begin with, and then more should those not stop it.
I would be surprised, in an actual serious war at sea scenario where on side was able to get off 16-20 modern anti-shipping missiles, and coming in on the heals of SEAD missions that targeted their opponents radar, that it is going to take 3 or more missiles per anti-shipping missiles to kill them.
I also suspect, that even then, that they will have less than a 100% chance of killing them all.
Also, that's why I said "theoretically". In a shooting war where the 052C/D has enough warning so that it is engaging enemy missiles at long range, there is plenty of time to assign only one missile per target and reassess the target after the initial missile makes contact.
As for SEAD, it's all or none, meaning you either destroyed your target or you didn't. It wouldn't take 3 missiles just because SEAD was there. It would still only take either 1-2 missiles or it would take none, because SEAD already killed its target.
Antiradiation missiles in the case of naval engagements are effectively the same as any other standard ASCM as far as air defense missiles are concerned. It's not like a ship is somehow more or less vulnerable to antiradiation missiles compared to ASCMs. Actually probably less since they are almost invariably air-launched which means the defending ship/radar can easily identify them and at longer ranges.It is likely in modern war at sea, that the opponent will be using, as I say, 1st anti-radiation missiles, which will home on the emmitter...and that they will also ave active ECM occurring at the same time as the ASM strike comes in.
Where did I say the ASuW capabilities of the 051B or 052B are "not effective"? I have said that they are LESS effective against modern adversaries like the US and Japan, and also more than enough for most ASEAN navies.So the idea that ASuW capabilities of a vessel like the Type 51B or Type 52Bs are somehow not effective is jut not so.
Yes it will be rare, which is why a single ship with 8 more missiles than another is not huge in the grand scheme of things. You don't need those 8 extra if you are dealing with ASEAN opponents, and 8 extra will be wholly insufficient if you are dealing with the US or with Japan. Besides, the PLAN will soon have only 5 ships (051B, 2x 052s, 2x 052Bs) that load 16 antiship missiles, as the rest of the Ludas are rapidly being phased out of service in the next few years. Most modern destroyers only load 8 ASCMs if they even carry any at all. Ships like the Slava with its rows upon rows of antiship missile canisters are almost anachronistic at this point in naval warfare history. I'm not saying 16 ASCMs on a ship are somehow definitely wrong, just that they are not as important as they used to be in the face of modern network centric air defense and advanced combat management systems where an attacker literally needs several hundred ASCMs to be able to penetrate such a defense.1st, a single ship will rarely be in a position where it is going against a task group of other vessels on the other side.
Second, each ship that carrier 16 missiles can add quickly to the more massive attack you mention.
