Latest Updates from PLA

Probably the biggest news to come out this week is the appearance of the Chinese Global hawk UAV. It's developed by CAC and has the name Sky Wing according to Huitong. This is the UAV in one of the airshows.

And you can find the video of the high speed taxing of this UAV here. Generally speaking, this seems like the second Global Hawk-like UAV that China has developed. WZ-2000, by Guizhou, is already in service with PLA Department of Chief Staff according to a recent PLA article. So, is this CAC version supposed to be more advanced and designed for PLAAF's use? I guess we will see more of this plane. It's almost surprising that we saw it unveiled so early (before even its first flight). Normally, this would suggest that the project is not very high in priority.

Also, it seems that there was a crash involving 2 J-8IIs this past week (I don't know the exact details). According to some sources, all of the J-8F planes in service have been grounded for now.

Onto PLAN, I have some image from 525 (a 054 class Frigate) and 138 (a 956EM class destroyer) from ESF visiting the port of Vladivostok. The Russians get a look at the military hardware that they exported to China.




I'm surprised that they didn't post news of this visit anywhere on the English news sites. Now, only 052C, 054A and 051C have not visited other countries making port calls.

Edit: I just got some fresh photos out of HP shipyard of the latest 054A. You can see the front mast forming now. And if you look carefully, you can actually see the aft-mast also.




And also, we got a picture of 2 more 022s in the HP shipyard. I'm sure there are more parked around the corner. We lost count of these little guys a long time ago.

J-8H stats and latest from the shipyards

So, the eyes have shifted away from the Olympics to the Shenzhou-7 mission recently. Even as this is happening, the shipyard construction in JiangNan and Huangpu shipyards. Here is a new photo from JN shipyard making waves.

With the new photo that we are seeing from JN shipyard, it's quite apparent that we will see a huge PLAN shipbuilding boom in this area. And for all the PLA followers out there, I don't think there can be a more exciting time. Just recently, we already saw at least 4 finished Type 022 FACs in the 3rd line of the Changxin shpyard (where all the military ships are built). Now, people are pointing at different sections trying to say which section is for what kind of ship. Of course, the speculation in the picture below is that it is the first section of China's first aircraft carrier to be built. I can't verify the validity of the statement, but I figure the work must have started already, since a lot of the parts are already supplied there. Give it a couple of years, we should see the ship really taking shape in this yard. The only question is whether we will see 1 or 2 carrier getting built at the same time. I suspect 1, since China likes to test out its design before continuing production. Other possible large ships would be the Type 081 LPH and Type 071 LPD, although it seems LPD construction is left to HuDong and Dalian shipyard. People are also speculating which large section is for the newly planned DDGs. Unfortunately, we only get aerial views of this shipyard, so we don't get those really nice up-close photo of the newly built ships anymore. For those of us that have been following 054A and 071 construction, it really is quite a disappointment. In many ways, this year hasn't been the building boom I predicted. Most of the large ship built have been medical ships, YuanWang ships and large tug ships. With JN finally seeing light of the day, we could well be seeing aircraft carrier, 071, 052D, 054A, Yuan and 022 being built at the same time.

Here are some photos from HD shipyard showing the sensors fit on the first F-22P. The pictures are for the front mast and the sensors supporting CIWS on top of the hangar


And this is a very good recent full view photo of the 3rd 054A being built in HP shipyard. It's showing the bow mounted sonar getting installed and the little platform for the AK-176M FCR getting installed. The platform for AK-176M was installed a few days ago. The windows are still nice and tiny.


Finally, I read some other interesting stuff on China's ASBM doctrine since the last post. It seems that PLAN placed heavy emphasis on the seeker of the ASBM. It expects to use land based OTH radar (I know, sounds crazy) and SAR satellites (I'm guessing the Yaogan series here) to track the location of the ship. Then, it will fire off a DF-15 or DF-21 to that location with not much mid-course updates. For a ballistic missile with a maximum speed of mach 6 (7400 km/h) , it will reach a target 2000 km away in less than 30 minutes. In 30 minutes, a carrier group can move at most 15 nm (< 30 km). In 10 to 20 minutes, a carrier group can move at most 10 to 20 km. The Chinese believe that the seeker on ASBM at really high altitude will be able to seek ships in a much large circumference. I would think finding the ship while traveling at such high speed would pose the largest technology barrier, since a seeker of something that fits a ballistic missile would be able to easily find a large ship within a 40 km radius if it's moving at much slower speed(an advanced multi-function fighter radar can detect ships at 300 km range). We know that fast AShM like Onix can find ships from that far out traveling at mach 3. The seeker for the BM would have to scan faster and have a really fast processor to process all the information. In the end of the day, all of the Chinese sources I have read express pretty firm belief that this ASBM doctrine is ready to be executed, while Western sources seem to believe that this is still being developed. I would tend to side with Chinese sources when I see this kind of conflicting views.


Interestingly from this list post, we saw what is probably the most detailed description of PLAAF tactic and J-8H performance. I don't ever recall seeing something so exact I guess. The source seems to be good, but it's hard to imagine how he was allowed to post something this specific. Anyway, for your convenient I have translated it.

It says that J-8H can operate over 80% of time, with over 18 aircrafts (each regiment has 24). It takes 1 hour and 20 minutes to prepare the plane to fly again from a new airbase after arriiving there from another. It takes a "Dadui" 2 minutes and 33 seconds to fly out and a "ZhongDui" 33 seconds to fly out. There are 16 seconds between the takeoff of 2 consecutive "Zhongdui". Zhongdui means a medium team and Dadui means a large team. I'm not sure what is the size of large team and medium team. It takes large team 9 minutes to land and a medium team 1 minute 44 seconds to land.

Combat format, combat flights normally operate in 2 to 4 4-plane formation making a large team. When intercepting aerial targets, normally operate in a 4-plane formation. Going after ground targets, normally operates in 2-plane formation. The optimum distance between 2 2-plane formation is 1000 to 1500 m. The planes in the 2-plane formation are 110 m apart.

Flight speed - It flies fastest at 17 km altitude, flies at 2337 km/h = 646 m/s = mach 1.9. At 200 m altitutde, it flies at 1010 km/h = 280 m/s = mach 0.82. It does ground attack missions at speed of mach 0.57 to mach 0.71. It intercepts planes at mach 0.65 to mach 1.6.

Flight altitude - the maximum flight altitute is 18 km. In ground attack missions, when doing A2A combat, operates at 2000 to 4000 m. When cruising, operates at 800 to 3000 m. The maximum altitutude is 12 km. Ground attack planes returns at 1200 to 4500 m, maximum altittude is 9000 m. When actually doing ground attack, typical altitude is 700 to 1600 m. Leaving bombing mode, the altitude is normally 500 to 2100 m. When abandonning diving in attacks, the altitude is normally 350 to 400 m. It will rise to 1000 m+ to shrug off target.

Ground attacking normally operates at 500 to 1500 m, lowest is 200 m, highest is 3000 m. When attacking aerial targets, operating altitude is 3000 to 15000 m, lowest is 600 m.

When doing ground attack, a regiment normally sends out 1 large team, which is 8 plane (explains the first part I guess), Joins the combat navigation route when about 15 km from target. Typically dives down at 10 to 20 degrees to attack, sometimes 30 to 45 degree. Everytime, a single team can attack 2 to 4 times, maximum 6 times. A single plane can operate in the target area for 6 to 17 minutes. When firing off missiles at 500 m in altitude, at 900 km/h, the launch distance is over 50 km. At 6000 m in alttutde, the firing distance is over 100 km.

Interception of targe - Attack method - At medium to high altitude, it typically uses 90 and 180 degree turns to point toward the direction of attack or use 90 and 180 degree turns to shrug off tailing attacks. Altitude difference is typically around 800 to 2500 m, minimum is 200 m, largest is 5000 m. In low altutde, use a lot of tailing and attacking from high altitutde, altitude difference is 500 to 2000 m. Entering attack at angle of normally 10 to 30 degrees, minimum is 0 degree, maximum is 70 degrees.

Radar is turned on normally 45 to 80 km from target, maximum of over 100 km (there might be some lost in translation here). First detect the target in medium to high altitude at 75 to 90 km, maximum of 110 km. Tracks the target in medium to high altitude at 45 to 70 km, maximum 80 km. In low altitutde, this happens at 35 to 55 km. When attacking target in medium to high altitutde, enters into 2 attacks per encounter. The first attack happens at 40 to 65 km away, maximum range is 80 km. The second attack happens at 20 to 33 km, minimum 4 km. Attacks happen 3 to 8 km apart. low altituude encounters happens at 3 to 8 km. And then it talks about operating with clouds around.

F-22P Taking shape + my thoughts on PLAN's ASBM program





It's really nice looking at these pictures because the first F-22P (251) is taking shape in front of us. We are seeing FM-90N and 76 mm being fitted on it. Actually, the FCR for the main gun looks exactly like the one for AK-176M, but the turret looks different. The sensors and the 30 mm CIWS are also looking really good now. If we go by previous exhibition posters, the tracking radar is TR-47C(MR-34) and the search radar is the export SR-64. SR-64 really is an interesting dilemma, because it's totally encased in a bulb on all the PLAN ships. It is almost hard to imagine that they are the same radar. We also see a Z-9C model on the helipad, which is consistent with what they do during the construction of other ships. I'm not going to make any guesses on when the sea trial will start.

The other thing I found interesting was Galarhn's post regarding ASBM. Actually, he quoted something by Robert Farley. So, this is something I recently spotted on ASBM from a Chinese military magazine interview with a naval base designer. The original text is as follows:

第十期兵工科技22页,记者对某地地总设、潜地总设王文超的采访,摘录如下:

记:一般而言,弹道导弹主要是打击大面积的固定目标,如果用弹道导弹来打击移动目标,可以实现么?
王:随着寻的末制导技术的发展,并且解决了运用到弹道导弹上的技术问题后,目前完全具备打击活动目标的能力

He was asked if ballistic missile can hit moving target. He said that with improvements in terminal guidance (after solving the technical problem of putting it on a ballistic missile), they currently have the capability to hit moving targets.

Ever since reports of Chinese ASBM came out, there has been a lot of discussions on whether or not this is true and also whether or not SM-3 has the capability of stopping it. This topic really has caused a lot of heated discussions on forums. SM-3 certainly has performed well in tests against the targets that it is designed against from all that I have read. I don't know exactly what the test parameters are, so I won't get into the discussion of which side will win in this kind of encounter. The idea of developing a ballistic missile with the accuracy of hitting a stationary USN aircraft carrier which only has a beam of 41 m is difficult. In that case, you'd basically have to achieve a CEP of 20 m provided that you can find the center of the aircraft carrier. Of course, hitting close to the carrier could also cause a lot of damage. If we use 30 m CEP as the barometer, hitting this kind of stationary target would be difficult, but not unimaginable. Consider that the export P-12 missile was quoted to have a 50 m CEP (and 30 m CEP with GPS guidance), it's not too hard to see a SRBM like DF-15 achieving such a target. We know from a previous Chinese article that DF-5 achieved a CEP of 250 m in the 80s after travelling 9000 km. If we think of all the improvements made in the past 20 years, it's reaonable to think that a MRBM like DF-21 can have a CEP in the 2 digits. I think it's even possible to imagine that DF-21 can achieve the 30 m CEP that's needed. However, is the terminal guidance that they put onto DF-21 good enough to track an aircraft carrier? Consider the speed that it is moving at as it is coming down, it's almost hard to see how it would be able to do so. There is also the other hard part of adjusting the direction to get there. Modern computers have certainly made this process much faster, but is it good enough? I guess we would not know until a test happens.

The other thing is that I don't think DF-21 is the only ASBM they are preparing. DF-15 has also been mentioned, due to it's shorter range and greater accuracy/adjustment. Of course, its range will eliminate the possibility of engaging a carrier (unless USN gets too close). There has also been the talk of JH-7A equipping some kind of a BM like B-611. If we ever see a picture of that coming out, I would be totally convinced that it's designed to engage aircraft carriers. So as things stand, the Chinese sites all claim that ASBM is a done deal. Most Western sources state that they are working on it, but still not there yet. The rest of us will just have to wait to see.

More pictures of the new 054

So, I got some more photos of the ship today. The first couple shows the bridge more clearly. It looks like the platform for the front mast is bigger in this one (at least to my eyes).




And finally a side by side comparison of the current 054 to the 054A from HP.

Chủ Nhật, 14 tháng 9, 2008

The new 054 in HP

So, we finally got some more clear photos of the 054 series frigate under construction in HP. You can see the photos below.






If we compare it to 525 and 529, we'd see that the lines leading to the bow on this specific ship actually looks more like 525. Obviously, it's not a 054, because it does not have the platform for HH-7 and seems to be keeping that for HH-16 like on 054A. The bridge looks like 529, except that the windows are much smaller and round (for RCS purpose?). The surfaces seem to be more stealthy than 529. They seem to be setting up the area where Sea Soul radar will go. We still need to see where the front mast is going to be with respect to the little platform on the bridge. So, the question is what is this boat? It's clearly not a 054 nor the first batch of 054A. The theory has generally been 054B or 054A+. Either way, the more important part is what kind of fit this ship will see. That will have to wait. One of the guys that post a lot of photos from HP mentioned that 054C and even D are being planned. So, we will just need to wait a few months and observe all the photos. As you may remember, it took months to confirm the number of VLS cells on 054A and that they are hot launched.

Zhuhai airshow + engines

So, we finally got a slight peak at what will be shown in Zhuhai airshow 2008. If you check Aviation Now, you will find this piece
日前,珠海机场获息,国产重要机型都将亮相本届珠海航展,其中部分有:3架歼-10(J-10)、2架歼-8B、1架轰油6、1架飞豹A。据了解,歼-10其中一架进行飞行表演,另外2架静态展示。轰油6将在此次航展进行空中加油表演。(张宝鑫 张艳)

The list above includes 3 J-10s (one doing flight demonstration and the other 2 are just for display), 2 J-8B, 1 HU-6 and 1 JH-7A. Also, the HU-6 will conduct in-flight refueling with I presume J-10 and J-8B. Of course, we should expect the usual suspects like JF-17, L-15, JL-9, UAVs, ARJ-21, MA-60, but J-10 will be the star of the show.

The other big news coming out in the past day is Guizhou Liyang's announcement of a new engine project. The article is posted below. It basically tells us that WS-13 (aka Taishan) finished the 300 hour long duration test at the end of the last year. And also mentioning the launch of the new engine. At this point, they could either be talking about WS-12 (aka Tianshan) or another turbofan engine in this weight class that is a generation ahead. So, it would be in the class of EJ-200/F414-EDE.


I know that the engine development situation in China is kind of confusing, so I will just look at the major engine makers and what they are working on.

Guizhou Liyang
Currently makes the WP-7 series and WP-13 series for J-7s. Due to the number of J-7, JJ-7s and JL-9s in PLAAF, this is probably the mostly used engine at the current time. It is developing WS-13 for JF-17. The project is obviously getting close to the original design certification. It will soon be able to fly with JF-17. The project that was mentioned here, which may or may not be WS-12.

Shenyang Liming
This one is most well known for its WS-10A (Taihang) and WP-14 (Kunlun) series engines. Since J-8II, J-10 and J-11B are the elite forces in PLAAF, we'd expect Liming to be doing pretty well in the coming years. At the current time WS-10A still has yet to receive production certification, but that should come in the next 2 years. It will then be considered mature. At the same time, Liming is also developing improved versions of Taihang and Kunlun. In the case of improved Taihang, it will be comparable to the improved AL-31FM series engines and be the main power plant of Chinese aircrafts. There are rumours that Liming will develop a more advanced version to compete for PLAAF's 5th generation jets. In the world of gas turbines, Liming has developed QC/D-128, QC/D-70, QC/D-168, QC/D-185 and QC/D-260 based on Taihang and Kunlun. So, it has also managed to corner the PLAN market.

Xi'an aircraft engine maker
At the current time, XAE is most well known for its WP-8 and WS-9 engines. Both are in full production mode (WS-9 just passed production certification this year) for aircraft built by XAC. Although, H-6K is using D-30KP2, so WP-8 is probably only used for replacements now. With the success of JH-7 series aircraft, WS-9 will still be in hot demand. More importantly, the WS-15 is well under way in XAE. This will be the future of Chinese aircraft engines. It is the only well known 5th generation aircraft engine project for China until this recent Liyang news.

608 Institute
This institute develops the remaining major item engines. It currently builds WS-11 series engine for K-8 and have received the ToT for licensed production of the AI-222-25K. It is also developing WZ-9 for the Z=10 helicopter and WZ-10 for future Chinese helicopters like the 10 tonne helo (or maybe even future Z=10 and Z-15). There are also some mysterious pieces on 608 in the past. This quote below discloses that they developed a turbojet that has already been tested with a plane. It's still unclear what this plane is, although people suspect it's a CAS aircraft replacing Q-5. It talks about developing a motor for UAV and starting certification flight for WZ-9. Looks like 608 has the future PLA helicopter and trainer/attacker market cornered.

608所的涡喷是什么东东
4月8日的航空报除了涡轴9的消息外,还有个涡喷的消息,文字如下:某型涡喷在完成先期技术攻关和技术验证机研究两个完整阶段后已成功装机试飞

4月15号HKB报道:608所07年某无人鸡动力装置关键技术研究顺利通过验收、某涡喷发动鸡在完成了先期技术攻关和技术验证鸡研究两个完整阶段后成功装鸡试飞;我国自行研制的具有完全自主知识产权的某型发动鸡在06年首飞成功、07年顺利完成科研调整试飞的基础上,目前已进入定型试飞阶段。。。


Finally, there are the WS-150 (or maybe WS-200), WS-500 and WS-850. These are the engines being developed for cruise missiles and small UAVs. I really wasn't able to find which specific factory designs and produces them.

So, that's a rundown on the Chinese engine makers for everyone.

Updates on PLA

So, I haven't had the time to post here recently, but hurricane Hanna is keeping me indoor today, so I will catch up on some of the things we missed. Obviously, the Olympics stopped, so we've finally been getting some news and pictures from China.
So, the first order of business is WS-10A. We've seen a new article on it out recently.

It just talks about good reviews toward the usage of the WS-10A. The users are rapidly reporting problems to the relevant teams and getting them addressed. This continual process will allow WS-10A to quickly become a reliable engine for everyone. I think this just indicates that they seemed to have adopted a more modern process in the maturation of an engine. As they become more technologically advanced, their methodology of testing and using engines is also getting better.

We've also seen a bunch of new pictures coming out. We got updated photos of what I think is the 3rd 054A being built in HD shipyard. It's kind of interesting that we've seen this ship while getting nothing from HP. There was a ship in there that we suspected to be 054A, but now looks to be something else. So, here are the photos of the 3rd 054A.



It will be interesting to see over the next few months if there will be any difference between this ship and the previous 4. It's been speculated that the new batch of 054A will be improved upon the first 4. I guess we will see.

The other interesting part is that the construction of surface combatants have not gone as expected this year. We've only seen this one 054A under construction and have not seen any movement toward 052D from JN shipyard. I guess a lot of ships will have to wait until 2009 before starting. However, we've seen a dramatic increase in the number of submarines showing up. Below is the 4th Yuan submarine that we've seen. Now, we can't see it well enough to see if this is the one that was shown to have a different hump than the previous 039A. So, I'm waiting for more photos of this submarine that contains more than just the sail.



And finally, we are finally seeing more pictures of 093 coming out.



So, I've read that several posters have tried to call the submarines in second/third photo 091G. But clearly, the sail is not sloped down as we saw on 403 photo from recent times. Yes, there does appear to be some difference in the limber holes between the 2 submarines in the photo (third photo is more clear on this). I suspect that the submarine further off with the interrupted limber holes is the newer version. It is either a newer 093 or possibly upgraded from an earlier model (403 was changed in that way.) With so many picture coming out, one can only suspect that the 095 project is going well.

And finally, some more photographs we've seen coming out recently of different parts of PLAN.

Medical ship + helicopter to be used on it




It's interesting how the helicopter model and the radar model name is different.

Other tidbits:
  • China is starting negotiation on IL-76/78 deal again
  • Pakistan has announced the purchase of 4 AWACS from China + negotiating on J-10s
  • China has submitted its military expenditure in 2007 to UN
  • China has started to recruit the first 50 pilots for naval aviation (ship-borne aircraft)
