These images are screen grabs from a local tv channel report on JF-17. Project director JF-17 said, JF-17 range has been increased in Block-II. BVR , Air-to sea and Air to ground weaponry has been integrated. Avionics has been updated which can absorb any weaponry of any origin quit easily. Production has been improved as well. 16/year capability has been attained, next goal is 20/year and ultimate goal would be 25/year
And IMHO Block-III induction depends upon how soon RD-93 MA becomes available, As per the russian document, stated year is 2018/2019. So we won't see Block-III before that
