Those were not F-15EX's those were much much older F-15E's they are being phased out in the next 10 years. They stopped building these things 8 years ago and combined they cost the US approx $93 million so sure its expensive still but its a third of what you are thinking because these were not EX's and were going to be retired in the next 10 years.
F-15E's the US Air Force received their last ones in 1999.
