Thank you very much for your question.
It's a very good question.
There's an old saying in the defence industry that goes, “The last 5% of performance is 50% of the cost.” I think that's a general rule of thumb that can be taken into consideration for the F-35. The fact is we don't really know what this plane is going to be capable of. Its testing is very early on. In fact, there has been some good news in the F-35 program. Last month they did their first test of flying the plane at night. We now know it works in the dark, which seems incredible, considering that they're already producing these aircraft and they hadn't actually tested them at night yet.
So it's very early days. This is the reason why, as you read this week, the Pentagon's chief officer responsible for purchasing the aircraft declared that the F-35 was acquisition malpractice—that it has gone into production far too early without proper testing. It was all of these qualifications and specifications, and performance was mostly based on computer modelling, which has turned out to be quite flawed. I think there are some real questions about what the performance is going to be of the F-35.
You also asked about this four generation, five generation.... To be honest, I've never found anybody who could explain to me clearly what the first four generations of aircraft were. It seems to be, ironically, a made-up generational number. I don't know if anyone has come before this committee who can explain what the first generation was, or what the second generation was. I've never seen that clarified. It's generally a marketing term.
I think there are questions about our needs. I did the report on the F-35 in October 2010, and at that point we said that first we need to be clear on what our capabilities are and what's going to be required of our aircraft. I think everyone agrees that we need to replace them, but with what kinds of capabilities--and is stealth, in particular, one of those capabilities that's required? The stealth factor limits the performance of the aircraft quite a bit. It limits its range, for instance. You can't put additional fuel tanks on because then it loses its stealth capability. You can't mount weapon systems out on the plane's wings. They have to be all carried inside the aircraft in order to maintain the stealth capability. It's something, for instance, that South Korea, which is about to enter a competition for the replacement of its aircraft, has pointed out as a major problem. They want to be able to use weapon systems mounted outside.
I think there are significant questions around the performance and whether the F-35 is the right aircraft. It can only be solved through a clear statement of the requirements for the replacement of the CF-18s, and we would have to see an open competition.
