Based on what? If you post so many sentence then I would expect atleast some depth.
It was impossible for F86 to down mig21... The MKI is a nice plane but everything has its advantages and disadvantages. With ECM going to ne era you can rething the BVR part. Yoou do remind you Indian text?
Cause the coffin mig21 had nice ECM the F15's could do nothing and in WVR it was a fine plane to avoid... Just check how old your Mig21's are... They got upgraded but do you really think that the ECM of JF17 is less? Let me wake you up. The ECM of the JF17 is perfected to counter any Indian hostility. If we are often reminded that SD10 seeker is copied from the same BVR you have then you should understand that we have a trusted friend China to do the math. Why else would we go for 250+ JF17's... Why else would you go for a few LCA's...
