I have some good news...
FC-20 prototype J-10B has passed all of it's technical and aerial trials, proven it's new user interface and suites, and will be coming to the PAF with an advanced Chinese engine which will undergo serial production in 2013. There are only minor delays in a supposed variant of WS-10 which has been tossed, is currently being tested. Airframe is made with more composite materials and the payload has increased. Also CFT's have been successfully tested and will also be a part of the initial 36 FC-20 package which will come with A-2-G and A-2-A munitions such as a new PLAAF ramjet bvr missile and of course SD-10.
Here is the best part... FC-20 is coming with ToT and there will be maintenance facilities and also some production capabilities which will keep this bird in service for at least 30 years.
It is also confirmed baat that FC-20 is not J-10A and China will be undertaking a MLU close to FC-20 standards in about 10 years when the PLAAF will have seriously ramped up J-10 production as they want in ideal terms at least 600 J-10B flying and all their old J-10A will have undergone the same upgrade as PAF's FC-20's except for certain western components which the PAF will supposedly obtain.
Also the RADAR was decided to be a high performing PESA radar rather than AESA which makes sense, as these would increase the cost of each fighter by at least 20-25%. There will already be Chinese awacs providing long range coverage, Pakistan is not the size of the US or Russia so the PAF will 99% not get AESA in FC-20.
It is supposedly going to be marketed against Rafale, Typhoon and other Western 4.5 gen fighters in a way which China says it has not done before and many air forces who would have bought MiG or Lockheed will get J-10A export variants. PAF and PLAAF will be the only nations flying the J-10B for foreseeable future.
