Was going through the Russian export weapons catalogue here: RosOboronExport and can across this below page. For the first time I have seen the marketing guys separate missile performance by target type. We see it a lot for the radar but not the missile. I am assuming here that beyond 50km the missile will have a less kinetic energy to hit an agile and evading fighter, but still good enough for engage a bomber.
This then makes question the “maximum ranges” we see for most missiles. It is very likely these maximum ranges are for the “easy targets” and will be a lot less for the evading fighter.
It sounds/is obvious when you think about it, but generally we miss/forget that reality. This applies to many other systems we discuss and compares here, talking of the crude/high level figures without defining the conditions or tests.
