MSOCS,
(as has always been quoted, i.e. Not inc engine)
You rather quickly discovered one of my cynical, baseless claims of JPO "creative accounting" practices. I know you aren't interested in the bigger picture, but you should be as it will determine how many will actually be bought, by whom and when:
The unit cost of the F-35A is $109.88 million (recurring cost) in FY 2016. The airframe costs $64.47 million, the F135-PW-100 engine costs $13.06 million, the avionics cost $16.74 million, while other costs make up the remaining $15.61 million.
The unit cost of the F-35B is $121.33 million (recurring cost) in FY 2016. The airframe costs $71.81 million, the F135-PW-600 engine (coupled to the Rolls-Royce LiftSystem) costs $30.82 million, the avionics cost $16.33 million, while other costs make up the remaining $2.37 million.
The unit cost of the F-35C is $117.83 million (recurring cost) in FY 2016. The airframe costs $86.09 million, the F135-PW-400 engine costs $13.06 million, the avionics cost $16.36 million, while other costs make up the remaining $2.32 million.
The total procurement cost of the F-35 program (incl. engines) is estimated at $319.12 billion + $55.13 billion in research and development (RDT&E) funds + military construction (MILCON) costs in support of the program in the amount of $4.79 billion. This adds up to a total estimated program cost of $379.04 billion (numbers are aggregated annual funds spent over the life of the program without price/inflation adjustments).The F-35 airframe will cost $318.39 billion ($270.43 billion procurement + $43.17 billion RDT&E + $4.79 billion MILCON), while the F135 engine will cost another $60.65 billion ($48.69 billion procurement + $11.96 billion RDT&E).
Now if Lockheed Martin can drag another 15,000 hours of labor out of each airframe constructed, the costs could drop to the figures you quote by 2020 which, BTW, includes the cost reduced P&W engine.
To give you a comparison to fixate upon:
In FY 2016, the unit cost of an F/A-18E/F Super Hornet is $67.2 million (flyaway cost) or $70.0 million incl. non-recurring and support costs. The cost of the airframe is $46.21 million, the two F414-GE-400 engines cost $10.72 million ($5.36 million each), and the avionics costs $8.71 million.
The F-22 is no longer in production. In 2007, the unit cost of the F-22A was $136.2 million ($148.7 million flyaway cost or $179.7 million incl. support costs). The airframe's cost was $87.74 million, the F119-PW-100 engine cost $10.03 million each, and the avionics cost $28.36 million.
Personally, I am glad the pilots seem to like the F-35. They damn well better and the F-35s had better do everything promised by the JPO and Lockheed Martin without the creation of a bottomless $$$ pit.
