Stealth is a technology that has evolved over time. We're now in what we call the third or fourth generation of stealth, F-22 being the predecessor, and F-35 being the successor to F-22 and building a lot on F-22 experience, taking it to another level, primarily in the area of ease of maintenance. We have substantially improved the fragility of stealth technology now, until it is very rugged; two of our three airplanes have to go to sea on ships, and therefore the technical characteristics have to be very rugged.
If you had your choice of being in a stealthy airplane or not being in one, you would want to be in one, because you have a significant tactical advantage in that there's uncertainty on the part of the adversary as to where you are and what you're doing, and there is certainty on your part as to where he is and what he's doing. That's a significant tactical advantage. When you couple that technology with the sensors we have now, to give the pilot a 360-degree view of everything that's happening around him and integrate all that data for him so that he basically is looking at a big-screen TV and seeing the world around him and not trying to manage sensors, you have a serious significant technical advantage over any other airplane that's flying out there.
We are very confident that this airplane is going to revolutionize. We're building this airplane for the next 50 years. We're operating some fighters today that are 50 years old, and we're going to be flying this airplane way into the future where technologies are changing more rapidly than they are today. So we have to have a good solid base on them. We have to have one that will evolve with time, and we think that's what this airplane does.
