Su-30MKK has integrated PL-12 and PL-8B now, and if Gaijin gives a later batch with Zhuk-MS radar it won’t be bad. It also uses L-150 Pastel RWR which is miles better than what J-11 and J-11A get.
Of course, I still hope for something like J-11B or J-15, but knowing Gaijin they might not decide to add it just yet.
It’s in the ballpark of 700kg lighter than J-11A, which is the common figure. Some sources claim even more.
It should be around 100-200kg lighter than the Russian Su-27 we have currently. The most important bit is the new engines though, which will give it a much better thrust-to-weight ratio.
WS-10A engines of the J-11B have 132 kilonewtons of thrust with full afterburner. For reference, AL-31F has 122.6 kilonewtons of thrust with full afterburner.
The very initial batch used AL-31F, but every J-11B starting from the second production block uses WS-10A. I don’t think Gaijin will add initial block J-11B.
We will know once the dev server drops and we get a look of the model. WS-10A nozzle length is different compared to AL-31F and all Saturn variants, it is shorter.
