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

If anything, they are slightly worse than the russian engines. China has been behind on domestic engines until very recently.

there is big progress in recent years, I’m sure it’s better than normal Russian engines

In reguard to the j11b, which is the fully domestic flanker, there are different batches under the j11b name with different engines. The original batch still used the AL-31F, while later ones used the ws10a which does appear to be slightly more powerful than the AL-31F, and possibly more reliable.

On closer inspection it does appear j11b is also around 1600kg lighter than the su27, so better flight performance all around

it’s said to be a combination of CFM-56 and AL-31F, and 10% better than AL-31F

If I recall correctly that was only on producing a ‘stealthy’ engine for the J-20, not to do with power output.

does the J-11A MLU use the same radar as SU-27SM?

i remember that the answer is yes, J11A MLU use N001VE

and a domestic advanced rwr I remember, which would be better than 27sm’s spo-15LM

Su-27SM has L-150 Pastel

it’s sm3 I think

Nope, current sm also gets it, they mention it in the devblog aswell

i see, it’s different from the suggestion information, maybe it can be considered as further upgrade after in service?

All Su-27SM, SM(3) have L-150 from the start, suggestion is just wrong.

The only further upgrade I know is that later models have better engine.

Sorry to point out stuff but most of the Chinese fighters nowadays, so J11BG, J16, J10C and the fifth gens too are equipped with the domestic engines that are deemed to be more powerful and more reliable compared to the Russian counterparts.

About the J11B, there were some issues of reliability with the first batch of WS-10 that slowed the process a bit until these engines were fitted back to these models with those reliability issues fixed.

We don’t need to wait until the J16 to have better performance, once again the J11B is one of those options, also when it comes to the SU-33 the Russians will have a by far worse version (can’t even use Fox 3s, and later abandoned the project) compared to the Chinese that instead decided to develop the B version and the T version that are state of the art 4.5 fighters at this point (PL-15 etc…)

Simply to give you an example China actually bought Su-35s to evaluate if the Russian engines were better or not and their conclusion was that they were ahead in that topic too.

So in game China will surely have better engines (not only that, i won’t talk about every single thing) compared to the later Russian versions of their Su-27.

I agree that maybe we won’t be seeing these versions in the next update, of course, but once planes like the Eurofighter start to roll out we can be sure to see those versions.

Edit: I see what your point might be, since versions of the J11 such as the BG were unveiled to the public in 2019, but this is far from when China actually started using the thing. One example would be the ZTQ-15, this tank was in use 5 years before being unveiled to the public in any sort of way, same with the new versions of the J-20, being the J-20A and S that we currently can see photos of when they takeoff from Chengdu.

One rarely mentioned improvement of J-11A MLU is that the more recent upgrades include a new domestic MAWS, so overall it is more or less slightly better than Su-27SM in air combat but worse in CAS role.

What what ???

I can’t seem to find info about the engines, might be some rumors amongst PLA watchers, but you can read this from Asia Times: “According to Asia Times, Chinese source remarked further purchase of Su-35 is not feasible as Russian jet offers little value over the Chinese J-16, due to the latter having superior radar, avionics and other equipment”

At the same time, it has a shorter flight range, speed, maneuverability and less resource. And there are questions about his Radar. What kind of improved avionics is unclear

I wouldn’t count on the range and less resource claims but that also depends on the style of aviation, the PLAAF does intend and already has a decent amount of tankers, making the range claim basically useless on its own. I don’t see the point of discussing the radar, it is an AESA radar and the Su-35 has a PESA, we are talking about different tech here and there’s not much “oh but what if its a bad radar anyway” that can cope with being PESA. In terms of weight the plane is lighter and has more composites used in it, also has radar absorbing material in its structure. Now if you trust wikies and stuff like that the alleged speed of the Su-35 is 2.25 mach at 11.000m, the one of the J16 is said to be mach 2 (doesn’t specify the altitude, it could be sea lvl)
