This is from F-16. Net
think J-10 if I can put it simply will be better than the blk15,40 comparable to blk 50/52 in performance and mission effectiveness and with a better radar can compete with the Blk60 and Israeli F-16I.
The reasons I can provide is the fact that Pakistan is developing the Jf-17 which is comparable to the blk 10/15 in yaw axis manouverability although not in the pitch due to the rd33 (mig 29 engine)with less thrust and with the cool DSI intakes (a rip-off from JSF) . BUt with this performance add the BVR capability that is going to be on this poor mans Viper which makes it pretty decent.
BUt the reason I rate J-10 is that Pakistan for its advanced fighter role has decided to immediately buy around 36 of the J-10. Now Pakistan has Grippen, Rafale and with that new Blk50/52 F-16s available for the slot. Along with the political aspect in this deal Pakistan choose the J-10 with which they seem to be very impressed with now. If you read the comments of PAF ACM( heading the Jf-17 Development and production program for PAF) a few years back when they evaluated the J-10, they clearly indicate that the J-10 had an excellent structure and aerodynamics and the Chinese were progressing very well with the avionics. Now that I suppose they have met the requirements of PAF (which they take very seriously
) it tells you about the confidence in the avionics and the complete system of the J-10. Therefore the J-10 can definitely be compared to the F-16 and may perform better in some flight envelopes and missions. Over all IMHO the J-10 may become far more mission effective than the Viper, but it will take a little time. J-10 is just a new fighter with pretty of time for improvement.
And oh the Ejection seats is not even an issue if Pakistan will buy it surely, it will definitely have Martin baker seats as replaced before in all the previous fighters like F-7, F-7PG, A-5s and even F-5s from China.
