Thank you, sir. That is an excellent question.
As to whether I have the United States' precise numbers, I do not.
Generally, I have a pretty good understanding of how procurement works in, say, a fellow middle power like Australia, and it's not that much better, I'm afraid.
It goes to the heart of the nature, often, of the type of procurement we acquire. As my colleague, Mr. Kasurak, noted, the more sophisticated aircraft complicate sustainment costs and intellectual property negotiations, and the list of variables at play goes on.
In terms of our having the unique situation of trying to manage a complex defence procurement, I'm afraid we're not alone in that regard.
