Thank you.
That's an excellent question. As Mr. Finn indicated, it's an options analysis. That's when the Department of National Defence is looking at what its needs are, what's on the market, and what it should buy. We support them in that role, because we do industry engagement earlier and earlier. We've found that this helps us to be precise about what is available in the market, what Canada can afford, and what fits with our needs.
I would point out, as well, that increasingly we're buying complex systems to put on platforms, whether on land, sea, or air. The acquisition cost is a diminishing portion of that. The real money is in sustainment and in-service support over the life cycle. Increasingly, it is about two-thirds of the defence cost, if you look at it. It's something we need to plan for, be ready for. It's a continuous cycle, as Mr. Finn pointed out—continuously maintaining existing equipment while you're thinking about refreshing it.
