Citando:
"The United States has spent over $320 billion so far to develop and acquire more than 2,400 fighter jets, according to the GAO report.
Dr. Michael Gilmore, the director of Operational Test and Evaluation at the Department of Defense until 2017, also provided a fairly searing depiction of the F-35 program in his FY 2015 Annual Report. He wrote that it would be problematic to make any commitment to a block purchase of the F-35 before November 2021 because of the technical challenges the program faced, but he did not identify fuel tubes as a specific issue."
