i will stick to what i said earlier. Blk 2 has more tech advancements than people have been "made" to believe. A new EW suite is among them, what has been confused is IRST and AESA, rest of technology has seen a major up lift and goes all the way to blk 50 standard. Sensor fusion and MMI is much better. It already has Datalink capability but it is Chinese/ Pakistani version and not the NATO Link 16 standard but this can be readily incorporated without much fuss.
@ IB
In China, new generation JFT avionics are on the test bench already. What i interpret from the "new generation" is 5th generation. Current avionics are already 4+ generation as they are fast, versatile and incorporate sensor fusion capability. Not everything is a rumor, but not all can be verified on internet either. Wait till the 2nd blk comes because it will surprise more than a few.
