mikip, I know we've done this here before, but I don't believe your costing for the F-35B. Almost everyone here will give you a different figure and it's hard to tell which one is right. What I do know is that it's higher than most people think (or wish to believe). There's a lot of smoke and mirrors involved.
This might help explain - until it gets discredited by someone that doesn't want the cost to be too high.
