So far, this is the most elaborate specifications that I have read about the F-7BGI planes BAF bought from China. BAF very seldom declares its purchases, but a select group of BD posters were criticizing it is not BVR capable. I was almost the only one to defend the purchase. These special people were showing fondness for some other expensive plane with almost the similar features of F-7BGI, but 3 times more expensive. Now, read also the small news below published by XairForce and it referrred to the news agency below:

The Bangladesh Air Force has F-7BGI Fighter Aircraft. New F-7BGI of Bangladesh AF - sixteen examples will be delivered as a stop-gap until new generation fighters (JF-17?) appear. These are arguably the most advanced F-7s ever built (J-7G2 airframe, glass cockpit, HOTAS, GPS guided PGMs, improved KLJ-6F radar with 85+km range and 2 target simultaneous tracking, WP-14C Kunlun III engine with 82 kN thrust).
