那來4000 億美金的研發經費啊,請不要把全計劃成本(採購+研發)搞在一起 (RDT&E)是550億美金,這資料也太扯了。 The total procurement cost of the F-35 program (incl. engines) is estimated at $319.12 billion + $55.13 billion in research and development (RDT&E) funds + military construction (MILCON) costs in support of the program in the amount of $4.79 billion. This adds up to a total estimated program cost of $379.04 billion.
