On the topic, I think that Boeing should ditch on the F-15SE idea and just sell up the Supers as stop gaps to the F-35, not replacements, because they are substantially different, but they would make bucketloads on F/A-18E/F sales to F-35 customers. The Aussie defence budget comparatively isn't particularly high, yet we opted (quite smartly IMHO) to buy 24 Supers to stand in for 15-20yrs.
