Chengdu J-10, History, Performance & Discussion

With the Pakistani government going to war against Afghanistan, perhaps we’ll finally see a J-10 face combat experience.

Technically, J-10CE was there to escort JF-17s when Pakistan conducted airstrikes on Iran on the start of 2024.

This source I found makes some interesting claims.
Here are some of the highlights that I’ve translated.

-It is revealed that two first-rate pilots of the PLAAF southern command theater, both flying the J-10B, demolished the opposition forces and went on the win the Golden Helmet DACT exercises in 2017, and that these photos seem to suggest them being J-11s, possibly J-11B since J-11A is no longer participating in Golden Helmet at this time, and are already considered second-rate.

-On an unrelated note, it is said that the J-10B was sent to the Cangzhou flight testing center of the PLAAF to square off against the J-11B, and that the J-10B secured a 4:1 ratio against the J-11B. Some even say that it was 10:1, an utter destruction of the J-11B. It is found that the J-11B, despite having an lower RCS than the original J-11, still had many surfaces which led to radar returns, mainly engine fan blades and the tall vertical stabilizers.

-J-10B is using an electronically-scanned array radar compared to the mech-scan pulse-doppler radar of the J-11B, and in the end J-10B was able to track and engage the J-11B much earlier than the J-11B engaging the J-10B. In a dogfight the J-11B fared even worse than in BVR.

-J-10B’s new DSI intake and improved AL-31FN led to a notable reduction in RCS, IR signature, and thrust improvement. Couple in the fact that J-10B’s nosecone is slimmer, the radar/radome is canted, and the intake, the radar return of the J-10B is said to be second lowest in the PLAAF, with only the J-20 having a smaller RCS. Apparently it is in the realm of 1 meters squared or even less, which would put it in comparison with the Rafale and Super Hornet in this regard.

-J-10B utilizes an AESA radar with a supposed detection range of 160-180 kilometers against a target of 3 meters squared RCS.

Isn’t J-10B PESA?

Well, according to this source it is AESA.
I personally think it’s an PESA.

In the context of War Thunder it won’t matter too much anyway, since Gaijin seems to model them the same.

This post was flagged by the community and is temporarily hidden.

IDK cause they did say the PESA had worse range performance than PD, which could very possibly happen as seen by N004 vs ANAWG9. I am just sceptical about the fact that there are no sources on how it even performs, which means if Gaijin so decide to screw it up there’s nothing we can do about it.

Well, some dedicated fan might be able to dig up something, I’m still not the most well-versed PLAAF watcher, so…

I think it’s really hard, as a plane that only productid few dozens, we can’t even know its rader’s name, information about it’s a PESA, is get from the blurry image.

Well… One could try the source I posted… I doubt it could be accepted, but idk.

Gaijin does estimate radar performance off of known characteristics… We know that J-10B’s radar has around 1200-1300 transmit/receive module, general size of the radar, as well as a general decription of the modules. So it wouldn’t hurt to bring attention to it and hopefully they don’t make the radar bad.

By all accounts, I don’t think the J-10B radar would be bad if the J-10B could easily defeat J-11B in BVR, it would need to jam 1493, which is a pretty powerful PD radar.

If all else fails… Maybe someone can try and get membership access to sinodefenseforum, It’s full of people that know much more than me, certainly.

That picture I thought was nice, but it could well have been J10C since the over exposure in the background. Any other way than the antenna on the back to separate them?

It is hoped that the CAS capabilities of the J-10B will be about the same as that of the JAS-39C, with at least four FnF missiles.

You just kinda have to take source at face-value, which state that it is a photo of J-10B.

Also, ngl early J-10 flight demos are much more aggressive than now
Might be because of that mid-air collision back in 2016 that they decided to tone it down.

So has anyone attempted to find hard numbers for the Cd0 of the J-10? I just find it wild that it has so much more drag at mach 1+ than every single top tier delta wing in the game.

Yeah, seems wrong cause it just doesn’t follow any consistent pattern. I also doubt that the decrease will be so small past Mach 1.5 considering it particularly had a number of supersonic optimising measures.

Classic gaijin nerfing a Chinese jet for no reason just because they’re better than Russian jets

IIRC, Gaijin changed the drag numbers past mach 1 because of an interview with a test pilot on chinese state tv, where the pilot claimed that the aircraft started vibrating concerningly past mach 1.4 at some altitude (I cannot remember the exact claim). So in response to this information about potential overspeed damage to the airframe, they completely neutered the ability of the J-10 to accelerate past mach 1 at all altitudes.

That is not a reliable source though for two reasons according to Gaijin’s own standards: 1. It was an ‘experimental’ jet, a prototype rather than a real J10, so we can not conclude that the same would happen to the production version as up to now there are no reports on similar circumstances with any of the serving J10s from 2005 to now, 2 decades. 2. It was said to start vibrating concerningly or what ever wording he used, but that does not indicate the drag need to be increased at supersonic speeds, as we know vibration is not caused by drag or at least not directly.

Gaijin also never publicly admitted to the fact that this is the source they used, since CCTV interviews and stats are not considered good enough for any bug reports anyways.
