More than a million spare and replacement parts for the F-35 Lightning have gone missing in the past eight years, estimated to be worth about $85 million, according to a Government Accountability Office (GAO) report as of March 2026. The report also said the F-35 office has not established procedures to effectively monitor reports of lost parts, and responsible property officers are not given the training or procedures they need to do their jobs.
