To say the F-35 has failed to deliver on its goals would be an understatement. Its mission capable rate is 69 percent, below the 80 percent benchmark set by the military. 36 percent of the F-35 fleet is available for any required mission, well below the required 50 percent standard. Current and ongoing problems include faster than expected engine wear, transparency delamination of the cockpit, and unspecified problems with the F-35’s power module. The General Accountability Office (GAO) has blamed some of this on spare parts shortages, writing:

[T]he F-35 supply chain does not have enough spare parts available to keep aircraft flying enough of the time necessary to meet warfighter requirements. “Several factors contributed to these parts shortages, including F-35 parts breaking more often than expected, and DOD’s limited capability to repair parts when they break.

There have been so many problems with the F-35, it’s difficult even to summarize them. Pilot blackouts, premature part failures, software development disasters, and more have all figured in various documents over the years. Firing the main gun can crack the plane. The Air Force has already moved to buy new F-15EX aircraft. Multiple partner nations that once promised F-35 buys have shifted orders to other planes. The USAF continues to insist it will purchase 1,763 aircraft, but the odds of it doing so are increasingly dubious. The F-15EX costs an estimated $20,000 per hour to fly. The F-35 runs $44,000. Lockheed-Martin has promised to bring that cost down to $25,000, but it’s been promising that for years. Former Air Force pilots have not been kind in their recent evaluations of the aircraft’s performance and capabilities.
