I doubt that the radar is BVRAAM capable. As for the range, even a small radar like that should have a range in excess of 30km. I would speculate 50 to 60km is possible using range while search. However, on a track while scan function it should go down to 20 to 30km. If the radar is the SY-80, which operates at Ku band, not like the KLJ-6E at X-band, the range maybe shorter but on the other hand, the resolving and tracking power is even greater.A while back I thought I read somewhere that the Bangladeshi F-7BGs are BVR capable and were armed with MRAAMs but recently I have read another article saying that its nearly identical to the J-7G in terms of avionics and only has a range of about 30km, and is armed with only short range missiles. Is this correct?
