Air Force testimony today that the FMC rate of the F-35 is 29%. It has been around 30% for over a year. It is a great airplane, but the maintainers can't maintain it. You wonder what the marine corps F-35 FMC rate is, they have a hell of a lot harder time attracting people than the AF and their operating environment is a lot tougher. The Navy better figure out how to keep the Super Hornet line going.
