I'll separate your question into two parts, if I may: my operational intent, and then the other part with respect to the north warning system.
The north warning system is part of NORAD's suite of equipment. I'm certainly not in a position to comment on the future evolution of its capability development, improvement, or recapitalization. Lieutenant-General Parent down in NORAD would best answer that question.
From my perspective, I take a bigger view of infrastructure. It's about the facilities I have for my units that are based in the north. It's about the infrastructure, in terms of communications, that I need to command and control, either permanent installations or forces as they are deployed out on the land. We have an emerging concept whereby we establish northern operational hubs as launching pads. We bring forces from the south strategically and move them out tactically from a number of different locations in the north.
When I say “infrastructure,” that could be a standing contract for a certain amount of support or services based on that concept. We use some of the infrastructure we have. We have contracts in place. We bring forces and ready kit from the south. By “infrastructure” I mean all of that, such that we are better positioned to launch, command, and control operations.
