It's interesting because in last year's edition of the Strategic Outlook, we had proffered the idea of a mixed fleet, emphasizing on the one hand interoperability, and on the other emphasizing that since we would not be able to afford as many F-35s, assuming it would be F-35s, that maybe we would be better served by having a mixed fleet. I think that proposal got a lot of people out of joint, and I think we've approached it in a slightly more balanced way today.
Interoperability is key, but then you have to define “interoperability”, and that's where interoperability between Canada and the U.S...no problem. But the moment you go outside of that realm, interoperability is very much in the eye of the beholder. I always give the example of the Saudi air force, which is very much the same as we have ourselves, but there is no interoperability between the Saudi air force and ours, or the U.S. one. That's one part of the element.
The mixed fleet...George, I don't know where we are today on that one, but since the debate on the F-35 is not resolved, we have made proposals that the F-18 Super Hornet might be an option, might be a solution. But the sovereignty aspect in our view is essential.
