Superficial costcomparisons can become even more skewed if that one service requirement is permitted to be revised so as to make it less exacting after the design that meets the more demanding specification has been set for the multi-purpose airplane.
Third, when deciding on drug approvals, European regulators may take into consideration cost and cost-effectiveness (including comparisons to other available therapies), whereas the FDA cannot.
When comparisons are adjusted to remove this disparity, the cost per flight hour of the F-35 is only about ten percent higher than that of legacy planes for a fighter that is far more survivable and effective.
