It’s always difficult to determine costs for various weapons and systems. Here’s an example that appears to be relatively straightforward. From a Defense News website article we see the costs for the next batch of F-35 engines (1).
“The cost of the modifications are included in the contract for LRIP 7, which was also awarded Tuesday. That award was for $592 million. When added to a previously awarded sustainment contract from last December, the total cost for LRIP 7 comes in at $943 million in funding for Pratt.
The lot covers 36 engines, as well as associated management and support.”
As I read this, the engine production cost is $592 for 36 engines which is $16.5M per copy. The engine acquisition cost, including “management and support”, whatever that is, is $943M which is $26.2M per copy.
Since you can’t, apparently, buy engines without “management and support”, the actual cost of an F-35 engine is $26.2M per copy.
No point to this post – just data.
