The day I was scheduled to fly against the Flogger, it ground aborted for mx....so I don't know....but USN 'Rising Fighter' program F-14s used our F-4s (clean) as reasonable export Flogger simulators at low altitude, both for performance and depressed angle only radar capability. There used to be a Flogger driver on this site around here somewhere who would probably know. I 'spect though with the late model Floggers and Varks it might have been a 'photo finish'.
