One of the corner-stones of the F-35 development for all stakeholders is CAIV. It stands for: cost as an independent variable. You can do the homework and find CAIV in various Joint Strike Fighter briefs throughout the program's pathetic history.
Yet, General Bogdan (linked in the last post), knowingly or unknowingly doesn't believe in CAIV. Because, cost is a dependent variable (see the PDF below).
Bogdan has $6B to finish F-35 development. That is it. There is no more money (or so we are told). Bogdan may have to go back to the warfighters and ask them what capability they want taken off to come in at the new cost ceiling.
What capability do you remove from something that hasn't proven any go-to-war capability?
The program's ill health is dependent on that $6B.
