Does South Korea not have any missiles for their F-15Ks? Both the F-35A and the F-15K use the same AMRAAMs.
I guess the problem here is resources, not logistics, since both the F-16 and F-15s of the ROKAF use most of the weapons mentioned in the article. 40 aircraft is not a small number given that the F-15K fleet is 60 strong; you would expect
at least a limited number of munitions would have been brought alongside.
