JSFf,
Slide 5 compares conventional Eagle with 5th gen. Slide 19 compares SE with 5th Gen. In any event, I tend not to put too much faith in manufacturers' glossy brochures I would rather base my opinions on defence analysis.
I wonder if, in this case of the ROK sales bid, they're comparing the head aspect RCS with the US F-35 or the version that Korea would get (and you guys, come to that). What do you reckon?
