Yes. For the clarity of everybody, I worked closely with Lockheed Martin on the F-35 initiative.
The reality is that we do need a replacement fighter. The F-18 was originally planned to meet its end life in 2020. It's clearly going to have to be extended somewhat beyond that time. It's a very capable aircraft. It's in ISIL now, in Kuwait, and will do the job there well, I'm sure. Ultimately, you'll get to a point where its capability cannot be extended beyond a certain length of time at any cost in some areas, and it's expensive to even go beyond 2020.
I think we can make a good case that we need fighters for our NORAD obligations, for our NATO obligations, for other obligations we want to undertake. I think it's important that we proceed now to make a decision on a new fighter. I think the analysis has been done.
I certainly support the concept of a fifth generation fighter, not just because of stealth but because of the information fusion and gathering capability, and of course multiplying it affects the task.
