A report by the U.S. General Accounting Office claims that the readiness of the F-35 Joint Strike Fighter is being hurt by so-called "sustainment problems"—basically, the inability for maintenance and repairs of the plane to keep up the pace—leading to aircraft being unavailable for flight operations. The report claims that lack of needed parts were a major factor behind aircraft unable to fly.
The GAO report obtained by Bloomberg News says the F-35s faced "significantly longer repair times" because maintenance facilities are six years behind schedule.
