There have been 60-70 F15 and F16s operating in Iran (could be more just found via public sources).

And when an F-15E was shot down they got spooked. They're relying heavily on missiles because it doesn't cause a multiday story in the news when one is shot down on its way to the target (and because they're incapable of thinking more than one move ahead, and because it's not their money...).
