This was the year when many of China's new military aviation projects appeared, so it was very exciting to all of the PLAAF followers. Although there weren't as many news coming out this year about J-20 and J-31, many other projects really came out and took center stage. So this entry will try to look at them.
Y-20 - Although we started see pictures of Y-20 performing low speed taxiing late last year, it did not make it's maiden flight until late January of this year. The second Y-20 prototype made its maiden flight very recently. It looks like this program is progressing well so far. PLAAF is desperate for something like Y-20 to not only do the role of strategic transport but also as the platform for next generation AWACS (and other C4ISR roles), large aerial tanker and airborne laser platform. It has been forced to purchase a number of refurbished IL-76s from Russia in the past couple of years as a stop gap until Y-20 comes into service in 3 to 5 years. I think there is a chance that they will also purchase some new built IL-476 since the production rate for Y-20 is likely to be low in the beginning. In my opinion, this is the most important aviation project for PLA.
J-20/J-31 - It has been a less eventful year for the 5th generation projects. Many of us expect the prototype 2003 to come out this year, but we were disappointed for most of the year (although there is some recent photo that indicate 2003 might be ready). It looks like major improvements are to be made in this third prototype, whereas the first 2 are probably more like technology demonstrators. J-31 has been making some more test flights, but it's not known at the moment what exact role it will have for PLAAF. Similar to J-20, this first prototype is probably more like a technology demonstrator while 601 Institute works on creating a prototype that satisifies all of PLAAF requirements.
Flanker family - While rumours about Su-35 purchase continues unabated, we do know that J-15 project has moved to production stage this year. We are still waiting to see production version of J-15 to appear on CV-16. That will probably happen next year. It looks like J-16 project is also moving toward a first pre-production batch. J-11B/S production has continued this year, but will probably be replaced by J-16 very soon. At which point, J-15 will be produced for the naval aviation and J-16 will be for the air force. J-16 and J-10B are likely to be the main multirole fighters in PLAAF until the 5th generation aircraft enters service.
J-10 family - The production of J-10A finally came to close this year with the 7th batch. Most recently, we saw the last J-10A regiment with the 124th brigade. Earlier this year, we saw J-10A with the 12th division. The 124th brigade maybe all J-10As or a mix with J-10Bs. We now have 10 regiments (FTTC, 44th, 1st, 2nd, 3rd, 24th, 9th, 15th, 12th, 124th brigade) in service with PLAAF, 1 regiment (4th division 12th regiment) in service with PLANAF in addition to 12 in service with August first flight demonstration squad. That will total to over 300 single and twin-seated versions of J-10As, which is a very healthy production run. We have already seen the first production version of J-10B in the air fields of CAC, so they should join service next year. In many ways, J-10B's flight tests lasted a lot longer (5 years) than all of us had estimated. That's probably a combination of 611 Institute/132 factory devoting most of their resources to the J-20 project and the complexity of changes from J-10A to J-10B. It will be the first fighter jet in PLAAF to have AESA radar and a whole host of new generation avionics. There are rumours of a J-10C variant under development, but it's unlikely to have anywhere near the level of changes from J-10A to J-10B. By that time, the production of both the hi (J-20) and lo (J-31) 5th generation fighter jet will both have already started.
Helicopter projects - Most recently, the much speculated Z-20 (the 10-ton general purpose helicopters) made its maiden flight. We can tell from the photos that it is heavily inspired (or cloned) from S-70 blackhawk series of helicopters. As shown with S-70 and NH-90, this class of helicopter can be used for a wide variety of roles for both the army and the navy. One would imagine Z-20 would be very popular in PLA too. It can replace Mi-17 and Z-8B in most of the transport and SAR roles, while serving as the primary SAR/ASW helicopter for medium sized PLAN surface combatants. The other project that will be very important is the Z-15 project. The first Chinese version using WZ-16 engine should be flying next year. Similar to Z-20, it should be a tremendous help for both the army and navy. It can replace many roles currently handled by the undersized Z-9 series of helicopter. Up to this point, the main problem with Chinese helicopter industry is the lack of helicopters between the 4-ton class Z-9 and the 13-ton class Z-8. Z-10 has now filled the space of 6-ton attack helicopter, but Z-15 and Z-20 will now fill the space of 7-ton and 10-ton helicopter to finally provide PLA with a full compliment of domestic helicopters.
UAVs - Two major UAV projects took step forward this year. The first is the X-47B like Lijian (Sharp Sword) UCAV from 601 Institute and Hongdu. It had it's maiden flight in November and really gives China a stealthy UCAV that can perform a variety of attacking roles. Going forward, much work needs to be done (like getting a new engine that fits the engine nozzle) to actually bring this into service, but looks like PLAAF is really putting a lot of resources in this area. The other major project is the "second generation" of Soaring Dragon. The first demonstrator version came out in 2011. After 2 years of relative inactivity, we saw it again this year with numerous modifications. It should eventually join PLAAF as a HALE UAV similar to RQ-4. Outside of these two developments, we also saw Wing Loong (similar to MQ-1 UCAV) joining service with PLAAF and numerous other UAV projects like CH-4 that are being developed for both export market and PLA.
Bomber/fighter-bomber - We continue to see the H-6K bomber entering service with PLAAF this year. I don't expect a large production run of this bomber, but it can serve as a bomb truck until a more advanced bomber (which is currently under development) comes into service. That is something I don't expect until later this decade. After much speculation, we've finally seen the maiden flight of JH-7B recently. Contrary to earlier speculations, JH-7B has very few external modifications from JH-7A. The changes are the inclusion of a retractable IFR, strengthening of wing/fuselage to carry larger/heavier missiles and a new generation of avionics. JH-7B is likely to be developed for naval aviation since PLAAF is likely to purchase J-16 in the role of fighter-bomber.
As a whole, this has been a very busy year for Chinese military aviation. The appearances of Z-20, the second Y-20 and first JH-7B have been very exciting to PLAAF followers. At the same time, it's great to see J-10B production finally starting. J-10B and J-16 should be the main fighter jet for PLAAF until the end of this decade. The biggest things to look for next year will be the changes in the third prototype of J-20, the appearance of a next generation bomber and the development of new UAVs.

2013 Chinese Naval Review
2013 was another interesting year to look back on for the Chinese Navy, even if we did not see the commissioning of CV-16 or the launching of 052D. Here are some of the progress of the major projects and the anticipated launching for next year.
Carrier Project - For much of the first half of the year, CV-16 rested in Qingdao while China continue to study what it learnt from 2012. As you will be able to find on this SDF thread and this link containing recent Jane's Article, China has built a naval aviation training facility with multiple take-off and landing strips along with hangars for J-15s, trainers and helicopters. By June, we finally had the second round of flight tests from sea trials for CV-16. After which, 5 pilots have been certified for carrier operation. So far, we have only seen prototype No. 552, 553 and 554 conducting test flights off CV-16. Hopefully as we go forward over the next year, we will see production versions of J-15s and more pilots join flight operations. We have also seen J-15 conducting flights with payload like YJ-83, AAMs, bombs and buddy store. This is still a very early stage of flight operations for PLAN. We should see continued expansion in flight envelope and scale of flight operations over the next couple of years. Without help from existing carrier operators, PLAN have to proceed slowly to learn all of the lessons of carrier operations.
The other part this project is the construction of new carrier. Whereas CV-16 has the designation Type 001, the first domestic carrier is already given the designation of Type 001A. By all account, it should be a STOBAR carrier similar to CV-16. The question at this point is what kind of changes we will see from the not so well designed Admiral K class. Work for this type 001A class has reported been started in the second half of this year in Dalian shipyard (which did the refitting work for CV-16). We saw modules earlier in both Dalian and JiangNan shipyard, but those may just be demonstration modules. Over 2014, we should see more pictures of the modules taking shape. We may see both Dalian and JiangNan build 1 Type 001A carrier.
Submarine Program - I've written extensively this year about China's nuclear submarine program. We finally saw a newly launched Type 093B + newly launched Type 094 from the GE photos. Based on Kanwa's measurement, the Type 094 is also modified based on the location of the hump relative to the bow. Based on all that we have heard, a lot of improvements are needed in the upcoming boats before they can really become the deterrent that China needs.
The conventional submarine program was also quite active, but a lot more under the radar. The type 032 testbed was unveiled in July, whereas the type 039B production continued. It looks like the first 8 to 10 039A/039B have now replaced the Song submarines in the 22nd flotilla at Daxiedao and the newer 039B submarines (2 to 4) are going to the 12th flotilla at Lushun. We have also seen a new submarine launched at WC shipyard that's either a new modified version of Yuan (Type 039C or a new designation). In 2014, it will be interesting to see what this new boat looks like.
052C/052D - Over the past year, we've seen the 3rd and 4th 052C join service. The 5th and 6th should join service sometimes next year. The progression of this batch of 052Cs hasn't been as fast as expected. We've seen them numerous times in sea trials and at naval bases before they were commissioned. The time from launching to commissioning is over 2 years compared to about 1 year for 054A. The first 052D went on sea trials this year. We saw that it is still using the Type 517H long range radar as 052C. Seems like Chinese navy really likes the anti-stealth quality of this radar vs the possible benefits of a more modern volume search radar like S1850M. Outside of that, it seems like Dalian shipyard has also started building 052D. I think this class will eventually reach 8 units, although there are speculations this might reach 12. Type 055 might be on hold as they are really ramping up type 052D production next year.
054A - The production of 054A has continued this year with 3 more units launching. We saw some changes on the 10th 054A from HD shipyard equipped with a new generation of variable depth sonar (also seen on Type 052D ships). By this point next year, we should have 20 054As + 2 054s in service. Not sure if that will be the end of 054A production finally, but this has definitely turned out to be the most successful of Chinese naval projects in the past 10 years.
>br/> 056 - This program has a chance to compete with Type 054 series in success. We have already seen 18 of these ships joining service, in sea trials or launched less than 2 years after the first launching. Most recently with the 5th 056 from HD shipyard, we saw a new large variable depth sonar installed in the back. This might mark a new ASW variant of Type 056 intended to replace the Type 037 sub-chasers. Other Type 056s are probably going to replace the other versions of Type 037s in service. This class may end up with 40 units by the end of its production run. At which time, all of the older patrols boats should be retired from active service.
AOR (Type 903A) - This year, the 2 Type 903A AORs in sea trials from Guangzhou and HD shipyard both joined service with East and North Sea Fleet respectively. That gives them a total of 4 Type 903 AORs. Most recently in November, we saw a new AOR under construction at Guangzhou. We will find out in 2014 if this continues to be a Type 903 or a new class of ships.
Zubr - There has not been much movement in the construction of new Type 071 or LHD, so the main amphibious project this year has been the import and domestic construction of Zubr hovercraft. In June, the first Ukrainian built Zubr arrived at Guangzhou. At the same time, the first domestic Zubr has been building at a brisk pace in HP shipyard and now looks to be ready to be launched. The second domestic Zubr looks to have started construction too. The original contract called for 2 to be built in Ukraine and 2 in China. I would not be surprised if more are built in China. It is quite possible that they will only end up taking one from Ukraine and end up with more than 4 Zubr. While I don't think the current threat environment calls for many Zubrs, it certainly would not be a suprise to see a production of 8 to 10 of them. We will find next year if that will be the case.
Looking back now on this past year, it did not unveil as many new platforms as 2012, but was still a very productive year in terms of newly launched and commissioned ships. Looking forward to 2014, I expect more new classes of ships to be unveiled. It would be interesting to see what that newly launched conventional submarine look like. I expect Type 001A pictures to start coming out. Works on a new LHD will probably start in HD shipyard and same with new AOR from Guangzhou shipyard. The pace of maritime cutters construction will continue unabated in the various shipyards around the country. One visible fruit of this modernization is the growth in the export of naval ships to other countries. Most recently, 2 Type 035 submarines were purchased by Bangladesh. With all of this optimism, one still needs to curtail some of the enthusiasm. A lot of sailors need to be trained to use all of the new hardware. The results of training all of the sailors to new ships and technology will determine the success of Chinese naval modernization programs. Although we don't hear as much like we do with USN programs like LCS, there have also been many issues with certain PLAN programs like 051C. Overall, that's to be expected out of such a comprehensive modernization effort.

Conventional submarine update
While this is still early, but it looks like a new type of conventional submarine has been launched in WuChang shipyard. Some on the Chinese forum are calling this an improved Yuan, but I see this to be quite different with quite noticeable differences in the sail, the height/location of hump, the shape of bow and the hull in general. Here is a good shot of it:

CV-16 Liaoning's sea trial in South China Sea
This week, CV-16 sailed forth with 2 051Cs and 2 054As escorts to South China Sea for what China calls a scientific and training mission.
There are some concerns that CV-16 was sent there for political purposes to intimidate neigbhouring countries. I personally think that's wildly inaccurate. As I talked about in the previous entry on 091, No. 404 (the first production version of Type 091) was sent to South China Sea for testing at PLAN's deep water testing facility in Hainan. It should not be a surprise that China's first carrier would spend time here given how little space it has to operate around the Qingdao naval base. One of well known posters on Chinese military forum recently posted the following list of uncompleted tests that will need to be carried through this time.
So there are a number of tests that will need to be carried out this time. In the long term, there will be probably multiple carriers home based in the carrier base in South China Sea. After all, there is far more room to operate there than around Qingdao. I think this will be the first of many trips that CV-16 makes to South China Sea until SSF gets its own carrier.

One of well known posters on Chinese military forum recently posted the following list of uncompleted tests that will need to be carried through this time.
- Temperature related tests - Due to the colder temperature of north, certain tests that require hot climate (like air conditioning systems and refrigeration equipments) can only be completed in South China Sea at this time of the year. All of this will happen in the relatively high water temperature of South China Sea, which cannot be replicated around Qingdao.
- Deep water tests - The Bohai sea shelf around Qingdao is generally pretty shallow. South China Sea has long stretches of water depths of greater than 100 m (several hundreds of meters in many cases). ASW tests, especially against deep diving submarines, can really only be carried out here. Other tests including under water communications, acoustic countermeasures testing and deep water anchor testings,
- Testing command & control - As part of having 2 051C and 054A in this sea trial, CV-16 will be able to test the command & control systems leading a flotilla formation. More C&C tests can be completed in South China Sea given the concentration of new combat aircraft and naval ships in the area (including the nuclear submarines stationed at Sanya naval base). He also listed that 054As are part of the flotilla due to their strong ASW suites, which is important given the number of foreign submarines that will be looking to gather CV-16 acoustic signatures. I tend to that's a lost cause.
- Testing the new Carrier base - There is a new carrier base being constructed in South China Sea. Having this flotilla there will test out the ability of the new naval base to support a carrier group.
So there are a number of tests that will need to be carried out this time. In the long term, there will be probably multiple carriers home based in the carrier base in South China Sea. After all, there is far more room to operate there than around Qingdao. I think this will be the first of many trips that CV-16 makes to South China Sea until SSF gets its own carrier.

Other new Chinese military projects
Recently, I’ve talked about future projects for PLAN’s nuclear submarine fleet and surface combatant fleet, because they have been the hot topics that have grabbed the attentions of PLA followers. This blog entry will focus on several other important projects that are under way.
The first of which is the next generation of diesel submarines. At the current time, 12 Yuan class submarines have joined service with PLAN. Out of which, the first 8 (including the original + 3 improved 039As) joined the 22nd flotilla replacing the 8 Song class submarines that were there. These boats are 330 to 337. Two of them were visited by the Deputy Chief of US Naval Operations very recently. The next 4 (338 to 341) joined service with NSF. Based on what I can gather from Chinese sources, it looks like we should be seeing the next generation of diesel submarine come out shortly. Although, we will probably see a few more Yuan (probably 4) join NSF to complete that flotilla. Back when Type 032 came out, I thought it might be the next generation of submarine, but it turned to be a replacement for the Gulf class missile test bed. One thought is that the next generation will be collaboration with the Russians based on the Amur class submarine. As I talked about in a previous blog entry, this project would make sense due to access to Russia’s latest generation of noise isolation technology along with single hull design. From all I have heard, the negotiation over this collaboration is continuing, but has not been signed off. China is looking to put its own engine (with AIP technology), sensors, combat system and weaponry on the boat. Due to the normal protracted pace of negotiation on an export deal, this project will not get under way for a couple of years even if it gets signed off. Also, something based on Amur class would be smaller in size than China’s existing fleet of Yuan and kilo submarines. I think PLAN will only be looking for a limited fleet of this type of submarine (maybe 4 boats) for shallow waters rather than as a replacement for the larger and more ocean-going Yuan submarine. From this deal, it will be looking for technology transfers in hull design and noise isolation technology that it can apply to future classes. If China does launch a new submarine class in the near future, the production of this boat must have started while Yuan class submarine is still ongoing, which means the design work would have started a while ago. From this, I would infer that the boat would have minimal input from any possible deal for the Amur class. Since the conventional submarines of SSF need to be replaced and submarines there have much greater room to operate, I think this new class will probably be a large conventional submarine like Yuan. It will be smaller than the Type 032 class, but building larger conventional submarines seems to be the direction that PLAN is going.
The other project that is already bearing fruit is the KJ-500 AEWC&C aircraft project. It is PLA’s second generation of AEW aircraft based on the Y-8/9 airframe. Unlike KJ-200, which sports balance beam radar, KJ-500 will be housing a large AESA disk like KJ-2000 plane. Until more IL-76 or Y-20 airframes become available for china, PLAAF is unlikely going to get any new KJ-2000 aircraft. At this point, we have more identified KJ-200s in service with PLANAF than PLAAF (although PLAAF unit does have more hangars). This could indicate that the radar of KJ-200 may not fully satisfy the requirements of PLAAF. A more powerful AESA radar using newer generation of T/R modules is developed and housed on the Y-8/9 airframe to produce KJ-500. We have already seen pictures of this radar on a Y-8CE test bed a couple of years ago. This year, we are seeing the first two prototype units of KJ-500 in the airfields. It will probably go into service with PLAAF over the next couple of years. By the end of this decade, China should have more IL-76 and Y-20 airframes, which would usher in a replacement for the KJ-2000 aircraft.
And finally, we have recently seen the second generation Soaring Dragon (Xiang Loong) prototypes appearing in the Chengdu air fields. We saw the original back in 2011 doing high speed taxiing runs, but it disappeared after a while. It may have been a technology demonstrator. The second generation prototype appears to be much smaller in length and wingspan. It also uses the canted vertical stabilizers + ventral stabilizing fins vs the single vertical stabilizer in the original. This and other more subtle changes indicate a stealthier profile than the original. It also features fairings in the fuselage that could house different types of sensors. Due to its smaller size and less powerful engine, it's unlikely to have the range and endurance of a predator, but should be more than sufficient for PLAAF at the moment. The partnership of 611 Institute/GAIC has already produced the Wing Loong/Pterodactyl UCAV (similar to MQ-1 Predator). With the Soaring Dragon project, it looks like they have won the competition to develop a HALE UAV for PLAAF. Similarly, the 601 Institute looks to have won the competition for long range UCAV with the appearance of Sharp Sword project. At this point, I think Soaring Dragon will probably join service earlier than Sharp Sword due to the greater complexity in the UCAV project, but it will probably take at least another 3 to 5 years for Soaring Dragon to join service.
The first of which is the next generation of diesel submarines. At the current time, 12 Yuan class submarines have joined service with PLAN. Out of which, the first 8 (including the original + 3 improved 039As) joined the 22nd flotilla replacing the 8 Song class submarines that were there. These boats are 330 to 337. Two of them were visited by the Deputy Chief of US Naval Operations very recently. The next 4 (338 to 341) joined service with NSF. Based on what I can gather from Chinese sources, it looks like we should be seeing the next generation of diesel submarine come out shortly. Although, we will probably see a few more Yuan (probably 4) join NSF to complete that flotilla. Back when Type 032 came out, I thought it might be the next generation of submarine, but it turned to be a replacement for the Gulf class missile test bed. One thought is that the next generation will be collaboration with the Russians based on the Amur class submarine. As I talked about in a previous blog entry, this project would make sense due to access to Russia’s latest generation of noise isolation technology along with single hull design. From all I have heard, the negotiation over this collaboration is continuing, but has not been signed off. China is looking to put its own engine (with AIP technology), sensors, combat system and weaponry on the boat. Due to the normal protracted pace of negotiation on an export deal, this project will not get under way for a couple of years even if it gets signed off. Also, something based on Amur class would be smaller in size than China’s existing fleet of Yuan and kilo submarines. I think PLAN will only be looking for a limited fleet of this type of submarine (maybe 4 boats) for shallow waters rather than as a replacement for the larger and more ocean-going Yuan submarine. From this deal, it will be looking for technology transfers in hull design and noise isolation technology that it can apply to future classes. If China does launch a new submarine class in the near future, the production of this boat must have started while Yuan class submarine is still ongoing, which means the design work would have started a while ago. From this, I would infer that the boat would have minimal input from any possible deal for the Amur class. Since the conventional submarines of SSF need to be replaced and submarines there have much greater room to operate, I think this new class will probably be a large conventional submarine like Yuan. It will be smaller than the Type 032 class, but building larger conventional submarines seems to be the direction that PLAN is going.
The other project that is already bearing fruit is the KJ-500 AEWC&C aircraft project. It is PLA’s second generation of AEW aircraft based on the Y-8/9 airframe. Unlike KJ-200, which sports balance beam radar, KJ-500 will be housing a large AESA disk like KJ-2000 plane. Until more IL-76 or Y-20 airframes become available for china, PLAAF is unlikely going to get any new KJ-2000 aircraft. At this point, we have more identified KJ-200s in service with PLANAF than PLAAF (although PLAAF unit does have more hangars). This could indicate that the radar of KJ-200 may not fully satisfy the requirements of PLAAF. A more powerful AESA radar using newer generation of T/R modules is developed and housed on the Y-8/9 airframe to produce KJ-500. We have already seen pictures of this radar on a Y-8CE test bed a couple of years ago. This year, we are seeing the first two prototype units of KJ-500 in the airfields. It will probably go into service with PLAAF over the next couple of years. By the end of this decade, China should have more IL-76 and Y-20 airframes, which would usher in a replacement for the KJ-2000 aircraft.
And finally, we have recently seen the second generation Soaring Dragon (Xiang Loong) prototypes appearing in the Chengdu air fields. We saw the original back in 2011 doing high speed taxiing runs, but it disappeared after a while. It may have been a technology demonstrator. The second generation prototype appears to be much smaller in length and wingspan. It also uses the canted vertical stabilizers + ventral stabilizing fins vs the single vertical stabilizer in the original. This and other more subtle changes indicate a stealthier profile than the original. It also features fairings in the fuselage that could house different types of sensors. Due to its smaller size and less powerful engine, it's unlikely to have the range and endurance of a predator, but should be more than sufficient for PLAAF at the moment. The partnership of 611 Institute/GAIC has already produced the Wing Loong/Pterodactyl UCAV (similar to MQ-1 Predator). With the Soaring Dragon project, it looks like they have won the competition to develop a HALE UAV for PLAAF. Similarly, the 601 Institute looks to have won the competition for long range UCAV with the appearance of Sharp Sword project. At this point, I think Soaring Dragon will probably join service earlier than Sharp Sword due to the greater complexity in the UCAV project, but it will probably take at least another 3 to 5 years for Soaring Dragon to join service.

The future of PLAN destroyers
Most recently, the 4th 052C joined service with PLAN as 151. Over the next half a year or so, the final 2 052Cs should also join service in the same flotilla. The first 052D started sea trials a little while ago and the construction for this program is proceeding very nicely. We have 3 052Ds launched along with modules for 2 others in JN shipyard. There is also speculations that Dalian shipyard also got works for 052Ds. The product run for 052D is expected to reach 8. That would mean a total of 16 052B/C/Ds. A big question is what will happen after this production run is over. These 16 ships will form 4 destroyer flotillas. At this point, 052D is already as fully loaded with weapon/sensor as its hull could handle. As part of PLAN's continuous modernization, a new Type 055 class is expected to be built to lead the next generation of PLAN surface warship.
There is a lot of discussions on SDF recently regarding whether or not this Type 055 class is needed, so I'm going to just jump in here to talk about what i think of this speculated class. If we look at recent new classes, typically the first one or two ship of a particular hull type gets produced with current generation of sensors of weapons. In the case of 054, it was equipped with radars, missiles and close in weapon systems that were already on other ships. In the case of 052B, it was equipped with newer subsystems than 051B and 052, but they were proven Russian or Chinese copy of Russian subsystems that were on Sovs. Although both 054 and 052B were said to use a newer generation of combat systems, the visible weapon subsystems were already mature. And the reason for that is PLAN generally does not like to create a new surface ship hull type (with new propulsion system) and also putting new weapon or sensor subsystems on there. When one considers how new some of these subsystems are to PLAN, it certainly makes sense that they would want to be conservative and evaluate them on existing platforms first. As a result of this, the new VLS, radar suite and CIWS were installed on 052C and 054A class.
And with the introduction of the impressive 052D class, a even more complete VLS (and associated radars) along with a new main gun, the HQ-10 CIWS and new type of variable depth sonar are squeezed onto this existing hull after already getting that new generation of 052C subsystems. I would expect this new VLS to be on all future major PLAN surface ships. From that stand point, any new missiles that's designed for this VLS would be usable by all PLAN surface ships post 052D. I do expect that the first 055 will use a lot of the subsystems that we already see on 052D, but with more VLS and larger radar or one with higher placement. The first couple of ships will be used to test out a new larger and more stealthy hull using a new propulsion system. There has been quite the discussion on SDF on whether this class is needed when China can just keep on mass producing 052D like it is doing with 054A. I think it's important to note that 8 052D + 6 052C is quite an extended production run for this class of ships. As PLAN becomes more of a blue water fleet, it believes that a larger platform with more modern propulsion system is required to be better suited for blue water operation. This would allow better speed and manueverability in escorting carriers, smoother operations in bad weather conditions/sea state and greater ability to lead a flotilla. On top of that, 052D's hull has very little left for expansion in the future and would not be able to support any future weapon system like laser or a more powerful ABM radar that would have greater power requirement than what the current propulsion system offers. The 055 platform does not need to be the size of a 12000 ton cruiser like some have suggested. Something along the lines of Arleigh Burke class or Kongo class with future expansion possibilities would more than satisfy PLAN requirements. Once PLAN is satisfied with the 055 platform, it will then proceed with installing new weapon subsystems.
Similary, although 054A has been one of PLAN's most successful program, it will need to be succeeded by a new platform using the new standard VLS along with a new type of propulsion system.

Type 091 and what it tells us about China's nuclear submarine program
Recently, there were a rather significant release by Chinese news on the performance of PLAN's first generation nuclear submarines 091 and 092. While these news releases probably don't satisfy the curiosity of many PLA followers waiting to hear about the latest generation of attack subs, I find the release to be quite helpful in understanding PLAN.
One of the things I really enjoyed doing is comparing the 091 program to the CV-16 Liaoning project. Bear in mind, the two programs happened in two different periods of PLAN history. The construction of the first 091 started in the late 60s and the last unit did not launch until 1990. Its development lasted through the political turbulent years of 70s and the decade of military cuts in the 80s. In comparison, the CV-16 development lasted through this past decade when PLAN had its most budgetary and political support for naval power projection.
In spite of all of this, there are also similarities between the two program. In both cases, China had to go alone with almost no help from outside sources. As a result of this, both projects proceeded in a very methodical manner. Aside from the extended research before they start doing work on the ships, land based simulation models were built to help train the crew members. They did not try to do too many things too quickly. For CV-16, they first practised carrier take-off/landing on land based simulation air strip before trying touch-n-go on CV-16 before finally giving each of the original J-15 crew a chance to do take off/landing. In between each steps, PLAN took their time evaluating lessons before moving forward. As we go forward, CV-16 will gradually practice more complicated take-off and landing scenarios in its training process. In the 091 project, the entire test program went through multiple boats. No. 401 went through numerous testing after it joined service in the early 1970s before being forced back to the dry docks for extensive modifications 10 years later and not emerging again until 6 years after that. The long endurance patrol testing that one would expect out of something like an attack sub did not happen until with No. 403 in 1985. Only after No. 404, the first production version of Type 091, was in service did PLAN really finish testing of all the critical mission requirements. In 1988, No. 404 went through deep dive testing to 300 m, submerged torpedo launching tests and sailing at maximum submerged speed of 22 knots. Obviously, the testing period of 091 was very long (over 15 years), but one can see the similar gradual process of expanding on the mission envelope with carrier operations.
The big differences between the two program are obviously the technical preparedness and budgetary constraint of the two programs. China certainly walked into Type 091 project about as technologically limited as one can be in such a strategic program. The first two units were basically test mules that are already decommissioned. Even No. 404 and 405, the production certified units of the class, took 12 to 13 years from laying down to joining service. That's something CV-16 project never had to worry about. China was as ill equipped as one could imagine to start a program like 091 from budgetary, technology and political support point of view. It was as well equipped as it could be for the CV-16 project.
At the same time, looking at the 091 program can also give us clue about the current and future Chinese attack submarines. One of the biggest challenges for the 091 program was getting a safe working nuclear submarine into a submarine at a time when China could not even build its own civilian nuclear plant. One can imagine that the reactors in Type 091 boats experienced its shares of nuclear safety and reliability issues over time. Due to the low efficiency of its generators, Type 091 could only operate at a maximum submerged speed of 22 knots. So I think that the biggest change from Type 091 to 093 was having a safe and reliable reactor that can sustain a much higher submerged speed (say 30 knots). We know that it took 13 years to launch the last unit of Type 091. Let's say that time was cut to half ( 7 years ) fro the lead boat Type 093 class due to improved technology and funding, that would still mean the first unit would've been laid down in the mid 90s. At that time, China's civilian nuclear technology was only able to commission the Qinshan-1 CNP-300 plant employing first generation safety/efficiency. One could imagine that even with improved safety and reliability, these reactors on Type 093 probably weren't very efficient and quiet. The Chinese bbs rumours of pebble bed reactors for 093 are quite ludicrous when one actually thinks about the timelines.
Fortunately for PLAN, China's civilian nuclear industry has made a lot of progress since then. The second generation CNP-600 plants were used in the Qinshan-2 project that were connected to the grid in the early 2000s. With the recent proliferation/localization of CPR-1000 plants, transfer of technology from the AP-1000 project and the development of CAP-1400 power plant, the Chinese civilian industry should be able to design its own 3rd generation nuclear plant in the near future. If we assume that similar progress was made in the military nuclear reactors during the same period in noise level, safety and efficiency, it would reason that quieter and more powerful reactor would be available to power larger submarines. Seeing that the most recent 093B submarine was launch sometimes last year, it could be using a new type of reactor available in the early 2000s that would be a full generation ahead of the ones available for the first two 093s. That could lead to smaller/quieter/more efficient reactors allowing for more space for noise isolation technology and more power available for greater maneuverability. For the next generation of attack submarine (Type 095 class), it should be using a reactor from around 2010 that will be another generation safer and more efficient. If 091 and 093 programs are good indications, the first Type 095 will also likely to be a prototype unit that will have problems resolved in later unit.
Of course, all of that is speculations on my part, but we rarely get new information on China's nuclear submarine force.
