One of the challenges we face right now, of course, is that we are so far behind in trying to understand the lethal nature of what the Russians and Chinese have been creating. We're still trying to go through the various infrastructure examinations of where they have to go.
We know that the high north has to be the location of some of the hypersonics in order to be able to respond, but it also runs into and goes back to the previous question about what systems. We also have to be talking about where we are going to be placing an air interceptor such as the F-35. I agree with Richard when he says it's the only real plane we should be looking at.
We also have to talk about having infrastructure that then can be looking eastward and where we can put the fuelling resupply equipment for these aircraft, because they have to be in the air.
We also need a higher capability to have our submarine assets going into what's called the GIUK gap, which is the Greenland-Iceland-U.K. gap, where we think the Russians will be coming in with this latest generation of hypersonics that are coming.
As well, we have to have the ability to be watching the Bering Strait. I don't have to remind this committee that the Chinese had four research vessels sailing up the Bering Strait obviously doing examinations for future submarine transportation routes, so we have to be watching that in that context.
I say those choke points are the most important to be covering.
