That's a fair question. When the requirements for the Joint Strike Fighter were first created--this would have been 10 to 12 years ago, when they firmed up what the various requirements were--one of the them, independent of the aircraft, was price. In the past, occasionally, it was, “We don't care how much it costs, make the airplane beautiful.” This time it was, “We do care how much it costs. It has to cost in this area, and you make the airplane as good as you can make it for that price.”
Now what they've done is made a very excellent aircraft, and they are tracking down the line to the price within a few...I don't want to say this out loud, but within a few million--because times have changed, materials have changed, and prices and things like that--per unit of the price that was set out as the goal for the program, That's why I think it's affordable, because it's very much in line with what everyone thought it would be when they started out on this great collaboration.
Secondly, I know the prices of other aircraft in the world. We hear them frequently. We see the Europeans buying a tranche here, a tranche there, and you see the number at the end of it. You can calculate what the approximate price is of those aircraft, with the wherewithal to actually make them fly, because the aircraft itself is not flyable without some additional support, in most cases.
We keep an eye on what's comparative across the western world, and from those day-to-day activities we're sure that it's an affordable aircraft and that it'll sell in the area of 3,000-plus aircraft. If it's not affordable, it won't, and we're confident it will. That's because we do pay attention. We see the costs coming down. We know that every time we bid, we bid less, and every supplier that's kept is bidding less because we're getting better at what we're doing. There's great price pressure on the aircraft from five years ago.
