One of the selling points of the F-35 is that it supposed to be significantly more reliable than legacy aircraft.
The Pentagon’s chief weapons tester said the next-generation F-35 jet continues to fall short of full combat readiness targets and, despite some progress on reliability issues, all three versions of the fighter are breaking down “more often than planned.”
None of the Air Force, Marines and Navy variants of the Lockheed Martin Corp. fighter are meeting their five key “reliability or maintainability metrics,” Robert Behler, the Pentagon’s director of operational testing, said in prepared remarks Wednesday before two House Armed Services Committee panels.

“The operational suitability of the F-35 fleet remains at a level below service expectations,” Behler said in the prepared remarks. “In short, for all variants, aircraft are breaking down more often than planned and taking longer to fix.”

Even with that 2020 target approaching, analysis to date shows that neither the Marine Corps nor Navy F-35 models are currently “on track” to meet their reliability metrics even as they log more hours, according to the latest assessment.
Among the key lagging metrics cited by Behler are “mean flight hours between critical failure” — a data point that refers to the time between failures that result in the loss of capability to perform a mission-critical task, or mean time between part removals for replacement from the supply chain.
Significantly, while the F-35 fleet demonstrated, over short periods, “high mission capability” rates reflecting the percentage of time jets are safe to fly and able to perform at least one specific mission, the jets “lagged” by “a large margin” the more complete measure of “Full Mission Capable” status, he wrote.
That indicates “low readiness” for combat missions “that require operationally capable aircraft,” Behler said.
Something is seriously wrong with our whole weapons procurement and development process.
