That's a very good question. Because of the new technology--the stealth, the interoperability that we will have with our NORAD colleagues—we will be the beneficiaries of this larger package of F-35s that will be operating over North American skies, patrolling our coast lines, because of NORAD. The optimum number of aircraft arrived at by experts like General Deschamps is 65. He'll be able to speak to that further in terms of the technical capability.
So because of all of the advancements that have been made in a fifth-generation aircraft, they can do what 78 aircraft are currently doing. Sixty-five will have that same ability--and perhaps more because of stealth, because of technology, because of interoperability.
