Okay.
It's my understanding that the planes Australia bought are just slightly older. They're a different block from the fleet we currently have here in Canada, which we bought from 1980 to 1982. I understand that upgrading them to our standards is going to be quite a bit of work.
When you look at the costs of upgrades, especially as you look at combat capability, you see our fighter fleet hasn't been upgraded in 10 years. I understand that with the Australian fleet it's even longer, plus their airframes are slightly different, so it makes plug-and-play a little more challenging.
Has that at all weighed into the overall factors on whether or not the purchase is rational?
