@ Areesh, no need to be so much disappointed. If the basic J-10 design comes with latest avionics and is as capable as the rumored J-10B, then whats the bad thing ?? Just not having a DSI makes any difference ?? Don't think so.
It seems due to some unknown reason PAF has made the decision to induct the aircraft much before the due time as told before of 2014-15. The J-10B design getting IOC by the end of this year and then another round of testing before formal production starting would have made the 2014-15 time line possible, but due to the need of urgency by PAF it seems the PAF has decided to get the basic design J-10 with its own requirement of Avionics to fill some gap.
F-16s have not come from the EDA stock as hoped and relations with the US have gone down in the past 1-2 years and even the Blk-52s are with restrictions and the codes for them are still being procured from the US. We were hoping to have something close to a 100 F-16s but we are stuck at the 65 F-16 figure, 34 older ones, 13 EDA ones after the loss of one from the original 14 and the new 18 Blk 52s, so we are still short of 2 full Sqds to reach the 100 mark of front line fighters to take on the enemy.
This short fall needs to be filled asap and the J-10A coming with PAF specified avionics is the best answer as getting F-16s from the US with current relations seems very difficult.
So, my analysis is that these J-10s are kind of stop gap measure / emergency measure to fill the gap created by no F-16s and by 2014-15 when J-10B would be in full production run, we will start getting more out of them.
J-10 with PAF specified avionics is gonna be one hell of a fighter and fully capable to take own what the enemy has currently.
