But there still remains a point that all these fighters cost so much to maintain and fly, while jf-17 block3 with aesa, better avionics can do MOSTLY everything that these other jets can do and still flight cost will be lower than that of an f-16. Its a really good bargain for a country like Qatar which is very small. But again i also have my reservation over this news.Rafale, EF and F-15E Strike Eagle are 4.5 generation only....... ..
I would rather say that JF 17 is not comparable at all because it is light weight. These are medium weight aircrafts with superior technological advantages. So, it would be better to wait for credible source... Thank you.
