That's another excellent question.
This program was founded in the very beginning as...half of our contractual requirements are written around sustainment of the airplane and that has never happened before in any acquisition program in the U.S. on the airplane side of the house. Sustainment is something we figured out later, after we built the airplane.
In this case, we have designed in reliability and maintainability features in this airplane that we've never had on airplanes before, because the maintainers wanted a bigger role and because everybody was complaining about the cost of operating these sophisticated airplanes. So we have the features built into the airplane. We actually have a contractual requirement that they be twice as reliable as the airplanes they're replacing and take half the time to fix. That calculates out to fewer maintenance man-hours, fewer personnel required, and all those kinds of things.
We also calculate the cost of the F-35 annually with a large group of people that includes representatives from Canada. They come down to our facility in Fort Worth for a week or so and we lay out every potential cost you could ever possibly incur on the program, including what it's going to cost to upgrade your information computers 20 years from now. We rack all those costs up so that everybody has wide-open eyes: “this is what it's going to cost to maintain the airplane”. There is no legacy airplane today that can collect any of those costs. They don't track them. They don't collect them in those categories. So there's no direct comparison, but this is what it's going to take to fly and operate this airplane.
We also have very powerful economies of commonality and scale. We're going to be maintaining the airplane around the globe in nine nations. We're going to have common spare parts. If you operate in a coalition operation, the airplanes will be maintained by a common logistics stream.
There are many other features that will feed into the cost of ownership and operation in the future. We're highly confident that the airplane is going to turn out to be a reliable, maintainable, and reasonable airplane to operate in terms of the cost of ownership.
The analysis that's going on right now, way in advance of the airplane actually getting into operational service, uses legacy cost models. Legacy cost models, when you compare them to legacy airplanes, don't include many of the cost elements we're talking about.
If you asked our government, I think they would tell you that there is more known about what this airplane is going to cost to own and operate than has been known about any airplane at this point in its development--and it will unfold as it goes. A large part of that ultimate cost to Canada is what Canada wants to do in Canada in terms of training centres, overhaul systems, and all that kind of stuff.
