This explains the operational squarden with PAF.Pakistan has started mass production of the JF-17 Thunder in January 2008 and more than17 JF-17 are with PAF.
I hope by the end of next year PAF will have its first 40 a/c
I believe 6 will be produced in Pakistan by the end of this year.
Next year 8-10 in Pakistan and 10-15 in China.
we do know that there will be a changed engine and avionics etc in the next block, but will it have some design changes also???
