Cost growth for ongoing Air Force programs above initial estimates accounts for a substantial portion of this 44 percent increase. In light of the role that optimistic estimating is believed to have played in exacerbating space acquisition cost growth, you requested that we examine (1) in what areas space system acquisition cost estimates have been unrealistic and (2) what incentives and pressures have contributed to the quality and usefulness of cost estimates for space system acquisitions. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-07-96/html/GAOREPORTS-GAO-07-96.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-07-96/pdf/GAOREPORTS-GAO-07-96.pdf GAO-07-96 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-07-96 Other Written Product GAO-07-96; Space Acquisitions: DOD Needs to Take More Action to Address Unrealistic Initial Cost Estimates of Space Systems; Accountability Cost analysis Cost overruns Defense cost control Defense procurement Procurement planning Program evaluation Program management Strategic planning Aerospace research Cost estimates Air Force Advanced Extremely High Frequency Satellite Program Public Law 109-364
