NORAD's role is to provide aerospace warning and aerospace control. I think that speaks to the particular nature of this question when it comes to a continental defence perspective.
With the over-the-horizon radars that will be developed as per the NORAD modernization, some of the space-based capabilities that we described earlier, the sustainment of the North Warning System and the upgrades that we're doing with our F-18s right now—the 36 F-18s as part of the Hornet extension project—and then the future fighter capability, we're developing the capabilities to better sense.
You're speaking also of the ability to counter small or micro UASs that are becoming much more prevalent in theatres, which speaks a little more to the Canadian Army role, so I'll hand that over to my colleague.
