The Defense Department’s auditor reviewed prices paid for 46 spare parts on the C-17 from 2018 to 2022 and found that 12 were overpriced and nine seemed reasonably priced. It couldn’t determine the fairness of prices on the other 25 items.
So if we extrapolate from the data, the majority of the other items were probably overpriced as well.
You could take it once step further and say the trust has proven to be violated, so things that are hard to price have a higher likelyhood of being gauged, too
