A pair of F-35s can strike multiple targets in a contested environment with no support save, perhaps, a tanker. To get two conventional fighter jets to a similarly contested target requires 10 to 20 additional aircraft. The strike jets must be accompanied by other planes to jam enemy radar, defend the attackers, and provide situational awareness. So even if the F-35 costs twice as much per flight hour as an F-16—it’s less than that, in fact—it’s still the more cost-effective option. Buying F-35s eliminates the need for other aircraft and the personnel, acquisition, training, and logistics that go with them. No economic argument against the F-35 is viable without that calculus.
