Can we really compare Tejas and JF 17 ??? By Indian Aerospace/Defense News

[Su-11]

Kopyo radar has its limitations

For using the full range of R 77 Mig 21 will have to use AWACs or SU 30 MKI

What limitation would that be? You know its range for a given target size, why would it use Su-30? And Awacs cannot guide a BVR missile!
