Marines Put F-35B Flight Costs 17 Percent Lower Than OSD

PENTAGON: By combing through the assumptions — some of them deeply questionable — undergirding the Defense Department’s official cost estimates for the F-35B and refining them, the Marines say the plane should cost 16.6 percent less per flight hour than the current estimate. Since the F-35B is the most expensive plane to operate, lowering these cost estimates for the Joint Strike Fighter’s Marine version would have a substantial impact on the program’s overall costs.

Anyone who has watched the Harrier or the F-35B knows that Marines pilots rely sparingly on STOVL mode. It’s only used for a limited set of tactical moves and, usually, for taking off or landing the aircraft. The great majority of the plane’s flight time — could it be as much as 80 percent? — would be spent flying without using the lift fan and STOVL.

The current CAPE estimate assumes $41,000 an hour for the F-35B a senior defense official said they will eventually bring the costs down to $30,000 per hour, with an interim figure of about $37,000. Schmidle also notes that the F-35B’s cost figures were extrapolated from the costs of the much older AV-8B Harrier.

Overall, once the F-35 replaces the three Marine aircraft — F-18, EA-6B, Harrier — it is designed to supplant the Marines will save an estimated $520 million a year in operations and maintenance costs in 2012 dollars, Schmidle says.
