I've been seeing some figures about the cost of fighters in WW2.
P-51s or F6Fs are rated around 50,000$...
P-47 around 80,000$...
P-38 at 13,000~14,000$....
F4U at a whoppin' 150,000$... (!)
Now, I'd understand twin-engined aircraft being more expensive, since it means double the cost of engines, fuselages, components, and etc etc.. but why's the F4U so expensive?
Any particular reason behind it's megalomaniacal price?
