The Cheetahs were sold to Ecuador. I don’t think a F-100 would fit; An F-404 would be feasible, but I don’t think U.S. companies would be keen on supporting it given it would eat into potential U.S. sales.
Thanks sukhoi! Yes small sales no margins and the support might eat up those margins. It would have to be a retrofit package for a ton of countries and do them all. Getting import/export approval of the engines is another matter as well. I typed my thoughts up quickly you are probably correct F-100 is big, but I remember a F-16 that GE tried to get for export sales with a J-79 in it which leads me to believe it would fit unless that GE engine is smaller than the F-100. The 404 is like a Small Block Chevy, it has been stuck in everything....
