As I indicated in response to an earlier question, I think one of the key things to take into account, as we move into the Arctic in a more deliberate and sustained way, is that it is not just physical capability in terms of ships. The Arctic offshore patrol ships, the Harry DeWolf ones, are going to give us a significant improvement in the RCN's ability and the overall Government of Canada's capacity to have a sustained presence in the north.
I mentioned Nanisivik as the start of a sustainable support capability in the high north. I think the other key capabilities to your question, which will help in that regard, are other investments that are happening in terms of surveillance, communications, space-based, territorial-based. All of these investments represent what can be characterized as a system of systems approach.
There is no one single solution to the challenges you've characterized. It really comes down to having an integrated network of sensors so that we know what's going on in the high north; having the communications capabilities that are required to operate in high latitudes because those are special requirements—not all communications operate in those high latitudes—and so there are investments required and investments that are planned in that regard; then lastly, having a set of platforms that can either respond if we know something's happening or can be pre-positioned to respond, as in the case of the Arctic offshore patrol ships, long-range patrol aircraft, and other capabilities we have in our inventory now and that are all also undergoing extensive modernization.
