Nick Schwellenbach, national security investigator at the Project On Government Oversight (POGO): “The Department of Defense rebuked Air Force demands for more C-17 cargo planes in favor of upgrading C-5s, according to a February 14, 2008, Pentagon letter and supporting documentation to Congress obtained by POGO and made publicly available for the first time. According to the letter from John Young, Undersecretary of Defense for Acquisition, to various congressional committees: “the Department reviewed several options for procuring additional C-17 aircraft and rejected those options as not meeting requirements and more costly to the taxpayer. Further, the higher costs of options procuring additional C-17s are unaffordable in the Future Years Defense Program.” The Air Force wants more than the 198 C-17s total they are currently projected to have.”
