Officials in the F-35 Joint Program Office are doing paper reclassifications of potentially life-threatening design flaws to make them appear less serious, likely in an attempt to prevent the $1.5 trillion program from missing another schedule deadline and budget cap.

The Center for Defense Information at the Project On Government Oversight (POGO) obtained a document showing how F-35 officials are recategorizing—rather than fixing—major design flaws to be able to claim they have completed the program’s development phase without having to pay overruns for badly needed fixes. Several of these flaws, like the lack of any means for a pilot to confirm a weapon’s target data before firing, and damage to the plane caused by the tailhook on the Air Force’s variant, have potentially serious implications for safety and combat effectiveness.
