Re: Harriers
There's all sorts of arguments that can be had about range comparisons, such as how much fuel you allow for combat. But one set of figures I saw suggested that the F-35B has a lower combat radius than a Misubishi Zero.
That 266 miles, when you include a substantial allowance for problems, is rather too plausible. 3 planes, and 3 hose units on a KC-10, maybe you can refuel all three planes at the same time, but it would be tricky flying, and hose units can fail.
