just to be perfectly clear, when you mention these prices, the equivalent prices for other aircraft would include sensor suites as well am I right? Like in the Super Hornet comparison. Also, by your calculations, this price includes weapons and some sort of maintenance (I suppose) that is included in the overall price am I right? If so, 180 million per airframe is not a lot more than other airframes and, considering bang for the buck, might even be a contender for the F-16... Pretty impressive considering all the cost overruns.South Korea's FMS request is now online for a requested 60 aircraft. The full package is worth $10.8b or around $180m per aircraft (whole package divided by numbers of aircraft only.)

Seems like the $180m - $200m package costs are fairly steady at present. With the exception of Japan (which I suspect includes substantial domestic manufacturing and hence the higher per aircraft / package price tag) the costs are more than reasonable compared to other aircraft types.
