Shenyang J-11, J-16, J-15, History, Performance & Discussion

That’s a problem because it doesn’t work that way. For other radar, each missile uses a different channel when launched.

In case of having one data link channel, if a new missile is launched after launching a missile, the existing missile will not receive the normal data link signal.

Only newly launched missiles will receive a normal datalink signal and this mean guided only one rather than two simultaneously.

That’s my point, in theory you can launch two but only against the same target… and only one gets proper datalink information

Hi, not at the moment, I don’t think there is reports on PL-12 at the moment

I think there have been several reports on PL-12, just closed by mod

Bold prediction for one year later : Here comes China’s most advanced Flanker the J-16 but it still uses the good old Su-27 RWR

Not really that bold tbh.
Since they need to gimp every single new chinese addition anyway

that’s fixed, something like placeholder data

It is fixed? Good to know.

The J-16D will come into the game with the SPO-10 because secondary Chinese sources aren’t reliable enough compared to their west counterparts.

China upgraded their J-11A fleet with MAWS but completely forgot about the SPO-15, common issue since they are clearly the worst air force in the world!

Chinese sources state that the J-11A retains the existing N001 and only upgrades the FCS to guide the R-77.

Do we know which chinese sources say that? A search through Baidu doesn’t reveal any source that could be used.

Also, the PPT I mentioned is the one presented by PLAAF Senior Colonel Li Chunghua at Northwestern Polytechnical University about the Falcon Strike 2015 training, which is sufficient primary source and shows more clearly than other unreliable western sources that the radar in question was modified based on the N001, not the N001VE.

The powerpoint actually lists it as the Su-27. Western and Chinese PLA watchers described the planes participating in the Falcon Strike as the oldest Su-27SK in PLA service. Contemporary western sources indicated that only the initial batch was delivered with the N001E (which had the FCS upgrade), with the second batch onwards having the capability to engage two targets simultaneously. This information was gained from interviews with Phazotron representatives in 1997, which is as close to being a primary source a secondary source can get. In the same source, the Phazotron representatives indicated that the only limitation for not having the ability to engage 4 targets was software, not hardware (China’s Military Faces the Future, James Lilley and David L. Shambaugh, 1999).

China is gradually improving the electronic subsystems on their SU-27s. U.S. fighter/attack aircraft excel in the areas of advanced radar, fire control systems that allow one aircraft to attack multiple targets, and defensive electronic countermeasures (ECM) that confuse radar and missile threats. For example, the F-15C’s radar can detect targets out to 100 miles and can track and engage multiple targets. The Phazotron radar on China’s current SU-27s have a search range of over 62 miles and can track 10 targets, but can guide anti-aircraft missiles at only two of the targets. But at the 1997 Paris Air Show the Phazotron bureau announced that the next batch of Chinese SU-27s will be equipped with an improved radar. When software upgrades are complete it will be able to engage four targets.62

And at the Paris Air Show, Phazotron’s director said the third batch of Chinese SU-27s will have an improved radar with a larger antenna.93 At MAKS 97 Phazotron officials noted that within six months it could develop the software necessary to allow this radar to engage four instead of the current two targets. Instead of an upgraded Phazotron N-001, it may have already delivered a variant of the Zhuk-27 radar, which also may be able to fire air-to-ground munitions like the Zvezda Kh-31 supersonic anti-ship missile.94

There is nothing to indicate that the planes that participated in the Falcon Strike training were the J-11A, not a J-11 with upgraded FCS. I am also slightly confused as I was explicitly told by a technical mod that no assumptions could be made on sources yet the decision to not give two radar links seems to be made on an assumption that a single source was definitely referring to the J-11A? Even though it clearly states Su-27, does not indicate whether it was a domestic kit built J-11 or J-11A, does not indicate whether it was a fully assembled J-11 or fully assembled J-11A, does not indicate which batch of J-11 delivery it was, and most importantly of all, does not indicate whether it is a J-11A at all! Meanwhile, sources indicating that later deliveries of the SU-27SK had an upgraded radar and processor to allow for simultaneous engagement of 2 or more targets were knocked back because it only indicated that it was the second batch of delivery, and did not explicitly state that it was the J-11A! I simply do not understand the difference in treatment for these two sources.

It’s not even a hard thing to fix-if they copy pasted the Su-27SM into the Chinese tree it would be more accurate than the current J-11A we have!

I’m on phone right now so I’ll send you a link to the following article:

歼-11综合改装工程主要围绕着发射R-77主动雷达制导来完成,首先需要改进的机载N001火控雷达,从相关资料来看,N001火控雷达一个缺点就是信号/数据处理系统较差,无法使用一些比较先进的算法,如快速博立叶变换等,这样就限制机载雷达的性能,不具备多目标攻击能力、对地性能较低等,由于更换雷达需要对飞机航空电子系统较大的改动,所以歼-11综合改装工程仍旧保留了N001雷达,但是采用了“附加”的形式增加了一个先进的信号/数据处理系统,由于信号/数据处理系统能力增强,新的系统用来支持新的武器如R-77导弹,以及新的工作模式,如对地工作械,同时还可能对接收机进行更新,采用了低噪声接收机,从而提高了机载雷达的性能。

这个问题严重制约了中国空军的现代化空战能力,所以,在进入新世纪后,“歼11综合改装工程”随即展开。该项目的主要目的,是让歼-11A战斗机具备发射R-77中距空空导弹的能力。同时,这批次的歼-11A战斗机还换装了部分在歼-11B战斗机上使用的机载设备和多功能彩色显示屏,算是“降阶版歼-11B战斗机”,也被称为歼-11A MLU型战斗机。

刚开始的时候,是打算将国产PL-12中距空空导弹集成到歼-11A战斗机上的。但这样做会导致整机航电系统大改,工作量较大,性价比不高。于是,在白俄罗斯588航空修理厂的协助下,我们决定仿照苏-27UBM1的水平,将歼-11A战斗机升级到歼-11A MLU的水平。

原本的N001机载火控雷达主要问题是数据处理系统较差,无法使用快速博立叶变换等先进算法。所以,歼-11A MLU仍然保留了N001机载火控雷达,只是加装了一套先进的信号/数据处理系统。这样一来,歼-11A MLU不仅具备发射R-77中距空空导弹的能力,而且还具备了多目标攻击能力和对地攻击能力。

2000年中国空军从俄罗斯引进R-77主动雷达制导空空导弹到货,因此让歼-11战斗机能够使用R-77主动雷达制导空空导弹就成为当务之急。作为新雷达投入使用之前的过渡措施,我们对N001E雷达进行了改进,技术合作方是白俄罗斯588厂。主要改进包括升级N001E雷达的信号/数据处理系统,换上新的计算机,以提高雷达性能,配合新的工作模式和武器。这次升级并没有对雷达进行全面更新,因此性能提高程度有限。

Also, the aircraft that participated in Falcon Strike 2015 is not the J-11A/Su-27SK.

J-11A cannot use the R-77, and the R-77 can be used starting with the upgraded J-11A. This is confirmed by the mention of the RVV-AE (R-77) at the top of the PPT. It also mentions the MAW as “导弹逼近”. This further proves that the aircraft that participated in Falcon Strike 2015 was a J-11A.

All Western sources confuse the N001VE fitted to the Chinese Su-30MKK and the J-11A upgraded in Belarus with the N001 to use R-77. This is not worth considering

Sina Military just a military channel under unofficial new media platforms, the content of the article does not even indicate the source of the message, it cannot even be considered as reposting second-hand information, and the end of the article said that

I know, I’m on my phone and can’t access the material, so I posted that article instead. Did I miss mention that?

then i suggest that you reply after the call, just forwarding a news article without a source as a response may seem disrespectful to the other party, especially he is seriously discussing with you

I’m not calling, I’m posting from my cell phone. I don’t know what are you’re talking about.

Before you talk to me about disrespectful, read again what I said.

I apologize to you, and i request that you release the information you hold about the radar used in J11A when conditions permit, and then we can discuss it together, cause there’s some inconsistent information

I upload most of the material I have, but sometimes it’s not possible for Chinese material. I will check if it is possible to upload it.
