Thanks for your thoughts.
I think you are far too high. They have no need for that many...and I do not believe the need will materialize in the foreseeable future.
As I said before, I can see:
06 Type 052Cs (this is already done)
18 Type 052Ds
12 Type 055s
When you couple th 36 very capable vessels with:
24 Type 054A FFGs
40 Type 056 Light Frigates
The PLAN becomes the second most powerful surface fleet in the world, and has the resource to meet what I believe will be its needs over the next 20+ years.
They do not need to match the US Navy in numbers. The US Navy has to maintain a very strong presence in every Ocean. The PLAN does not. The PLAN will be focused primarily in the Western Pacific, and in the SLOCs across to Africa and the Mid East.
Now, the numbers will vary somewhat...and as they age, new upgrades/variants, or new designs altogether will be created. But I believe they will maintain a force structure like this.
Of course (though this is not the thread for it) you have to remember at the same time that they are going probable maintain on the order of 48 SSKs, and probably end up with 12-18 SSNs.
Very powerful order of battle...and over the next ten years, all of it will be made up of modern, capable designs.
(A bit of a late reply)
I've always maintained the idea that 48 DDGs (of 052C/D and 055 displacement) and 48 FFGs (of 054A and 054B/057 displacement) would be the optimal critical mass for the PLAN to reach.
I do agree that the idea of 39 052Ds and 27 055s is way too high. Personally I doubt the PLAN will build many more than 12 052Ds; at the moment I'm of the opinion that mass and serial production of 055 will commence after JN and DL finish their last 052Ds on order in a few years time.
I know I'm jumping in late on the anticipated production runs and total numbers of Type 052Ds and 055s, but, I do so enjoy these types of discussions. Thus, based on my, albeit simplistic, geo-spatial analysis, I'm thinking these types would be deployed in a two-tiered strategic system.
First, and foremost, I'd expect a bastion defense type scheme extending in-depth A2/AD coverage out to ~800 km from the coastline in the open sea zones. In the east sea, this would encompass the Ryukyu Islands zone and, in the south sea, the Paracel Islands zone. To achieve this objective, I'd anticipate ~12 052Ds and ~6 055s each for the east and south seas and ~3 or 4 of each for the north sea. So, to simply achieve this, fundamentally defensive, objective, I'm anticipating ~27 052Ds and ~15 055s.
Secondarily, I'd expect the deployment of expeditionary forces in both the east and south seas to provide the offensive component within any strategy of power projection. I'd anticipate that these forces would comprise ~6 of each platform. So, adding these ~12 of each platform to the ~27 052Ds and 15 055s, gives me a total of 39 052Ds and 27 055s. And, notice, which I'm sure some will, that I haven't even considered units deployed with CBGs/CSGs, although, the expeditionary units could well fulfill this function.
Oh well, my 2 cents, or 1.76 euro cents!
Your entire post however, misses out the importance of frigates in the PLAN order of battle, as well as 056 corvettes.
The availability of frigates means that the PLAN can do with less 052Ds, as 054As and the next generation frigate will take on many of the closer in air defence and ASW roles that 052D will have taken, while being modern and blue water capable.
A large expected number of 056 corvettes (rumours have suggested around 60 once it's all said and done) will mean the PLAN can patrol ECS and SCS during peacetime with corvettes rather than destroyers, and 056s can also do ASW missions in green water and within the first island chain during wartime.
My idea of 48 DDGs, 48 FFGs would be broken down like this:
-8 DDGs and 8 FFGs per fleet will be permanently available at port or patrolling in yellow sea, ECS or SCS. that gives 24 DDGs and 24 FFGs total i.e.: half of the surface fleet, for any western pacific contingencies either in yellow sea, ECS or SCS or beyond, and would operate either as a series of SAGs, multiple CSGs, or a combined task force including anything from carriers to LHDs
-4 DDGs and 4 FFGs per fleet will be under refit or giving their crew landside rest. So that is 12 DDGs and 12 FFGs total (i.e.: one quarter) at anyone time that is unavailable
-4 DDGs and 4 FFGs per fleet that are deployed on blue water operations, so 12 DDGs and FFGs (i.e.: one quarter) at any one time that will be as part of an SAG, CSG, ESG, or just a pair of ships. So that's basically 3 CSGs, ESGs/ARGs, or SAGs worth of surface combatants (assuming 4 DDGs and 4 FFGs per group -- which is actually larger than a typical USN CSG escort group which is made up of 1-2 Tico and 2-3 Burkes), or whatever combination or recombination of ships one wants to deploy depending on the situation. Maybe a single large combined taskgroup of 10 DDGs and 8 FFGs escorting two carriers and two amphibious assault ships in one theatre, with 2 DDGs and 4 FFGs for pirate hunting in another theatre. Or maybe you only want to deploy DDGs and FFGs to launch cruise missile strikes against a 3rd world country that is threatening your interests, so you deploy 4 SAGs of 3 DDGs and FFGs each around it and carriers aren't part of the equation at all.
Overall, what I'm suggesting is a doubling of the current 24 DDG + 24 FFG fleet that we currently see among the PLAN's frontline destroyer flotillas to 48 DDG and 48 FFG of fully modernized and blue water capable frontline combatants.
It is unrealistic to expect the PLAN to fight a multifront war simultaneously, and chances are any conflict will not make the PLAN "limit" itself by only deploying one fleet into battle while leaving the other two at full force in their respective areas.
For instance, an ECS war might cause the PLAN to deploy all of its available East Sea Fleet combatants as well as elements of North and South Sea Fleet, if for example there is little risk of high intensity action in the SCS.
It is also unrealistic to expect any PLAN blue water taskforce to survive a high intensity global conflict against the US until at least 2050 due to the sheer prevalence of USAF and USN bases around the globe which provides overwhelming logistics and air support to any US military elements, which China simply cannot match (and shouldn't seek to match).
Therefore, it is my opinion that any PLAN fleet up to 2050 should seek to achieve two overarching goals:
1: achieve the ability to fight and win an air-naval war in the western pacific against a high tier navy or more (i.e.: JMSDF, or the USN pacific forces),
in conjunction with supporting land based air force and 2nd artillery. For navy procurement, this will require a force of modern surface combatants that range from cruisers, destroyers, frigates, corvettes, down to FACs, as well as aircraft carriers with fighters and fixed wing AEW, ASW helicopters, and ships like amphibious assault ships, AORs, submarines, as well as land based navy MPAs, SOSUS, UAVs, subsystems, as well as larger overall supporting logistics
2: achieve the ability to implement permanent blue water operations on a scale that allows the PLAN to defend SLOCs against non state actors and 2nd tier foreign military forces or navies, as well as the ability to project air power, cruise missile strikes, and amphibious assault that will allow limited unilateral or multilateral action against a 2nd tier foreign state or to protect and/or evacuate a meaningfully large number of PRC expats that require assistance. This basically includes all elements of CSGs, ARGs/ESGs, and SAGs depending on what the situation needs (carriers and airwing, amphibious assault ships and airwing, cruisers+destroyers+frigates, submarines, a large number of large AORs, limited foreign basing/logistics support networks, and extensive satellite communication and guidance capabilities).
In fact I would say to achieve goal 2 is in some ways easier than goal 1, because goal 2 doesn't put the PLAN against a high tier navy like USN or JMSDF and it requires less integration with PLAAF and 2nd Arty and requires a smaller number of ship types and supporting aircraft. I.e.: no need for SOSUS, or MPAs, or corvettes for goal 2.
