Guys the original topic was PAF should have invested more on J10.
There ar equite a few ythings to consider. China has been working on J10 since the early ninties. It took a step back in 96 with one of the prototypes crashing. A lot of changes were made as a consequence. To be honest the tweeks with J10 are still going on.
PAF wanted a quickfit replacement aircraft for its ageing fleet that would be easy to acquire maintain and its expertise absorbed in its own infantile infrastructure.
If you look at the requirement of PAF with the evolution history of J10 you will understand why PAF went for the thunder instead. I am not even certain to what extent PAF could have contributed to the J10 programme. Thunder on the other hand was a low priority project for China so cost sharing seemed a good idea. But for J10 we would not have had that strong a case.
Also induction wise we will not get j10 till 2014-15, as China has an urgent requirment to replenish its ancient stock as well. It is not building J11s quickly enoughtherefore for it the J10 is the mid end plane.
However we would not have been able to do with the J10 what we have done with thunder. As such it was the right choice to go for Thunder instead.
