How much does an F-35 jet engine cost?
The Pentagon’s most recent Lot 18 agreement with Pratt & Whitney has raised the F-35A’s flyaway cost back beyond $100 million. Each F135 engine now costs an average of $20 million, up from Lot 17’s $14–15 million. Billed as the most expensive fighter jet in the world, the F-35A Lightning II costs about $82.
