From the information I have, this project not only has the cost of the acquisition and whatever infrastructure changes we have to make to it, but it also includes a 30% contingency. Again, when you're dealing with the kind of technological evolution of an aircraft of this nature, it is appropriate.
Indeed, it depends on when you buy the aircraft off the assembly line, which kind of determines the cost as well. From the information I have, one of the reasons that government over the years has upgraded our CF-18s is that they could last until 2017 to 2020. So we were buying the aircraft off the assembly line when the cost actually fit for us.
From my standpoint—and again, the commander of the Royal Canadian Air Force can get into more detail—65 is the minimal operational requirement for us. We need to have these aircrafts, both for the sovereignty of Canada and to meet our international obligations as set by the Government of Canada.
