For points defence PLAN got HQ-16 and FL-3000.
FL-3000N is like Barak 1. No issues there. It would be nice if you get a 360degree capability like Barak 1 through using VLS. Tier 1.
HHQ-16 was derived from the Shtil-1. It is an older generation missile now. I don't think Type 052C is carrying it though. Maybe I am wrong, but only if you can provide more info about it. This is something that can go into 052D's VLS, could be quad packed too. But it has half the range of the Barak 8. In case you build something better, this would form the second tier of your missile defence. Tier 2.
HHQ-9 serves as a long range SAM with limited BMD. Altitude of 30-40Km, range between 150 to 250Km. Tier 3.
What you may be looking here is the beginning of a proper BMD system if you get similar size missiles as HHQ-9 to achieve altitudes between 100 and 300Km and a range of 400-500Km traveling between Mach 8 and Mach 12 like the SM-3 on AEGIS. Tier 4.
So, for carrier fleet defence Tier 1 and Tier 2 are plenty with Tier 4 being area defence against BMs. Don't know if Tier 3 is necessary, maybe it is good to have.
In case of IN, we have an excellent Tier 1 and Tier 2 capability with Barak 1 and Barak 2. Hopefully Tier 3 and 4 will come online with P-15B and P-17A, AAD and PDV. But we have enough to maintain a CBG now against the threats we face.
In case of PLAN, Tier 1 seems to be ready. A VLS will make it better, but not necessary. Tier 2 does not seem to be ready because we know 052C does not have HHQ-16 or equivalent(maybe). Tier 3 is ready. Tier 4, same like IN. Still waiting.
In case of USN. Tier 1 is the RIM-116 equivalent to FL-3000N. Tier 2 is the RIM-162 ESSM with a range of 1.5 to 50Km. Tier 3 with RIM-174 with a range of 250Km. Tier 4 is the AEGIS BMD with the SM-3, altitude of 150-250Km and range of 500Km.
Tier 4 is not needed on every ship, but Tiers 1 through 3 may be important for overall fleet defence.
Let's not forget both ROKN and JMSDF have all 4 Tier defence systems.
