It's very good observation.
We obviously have the fighter jets that play an important role in NATO, and the tankers, as we've talked about, for providing air-to-air refuelling, given the distances that are involved. We also make use of our other air resources in the Canadian Forces to conduct surveillance operations. We have maritime patrol aircraft, which regularly conduct surveillance missions over the approaches to the eastern and western seaboards of Canada.
We have missions that go up into the Canadian Arctic to survey the Arctic land mass, but also the seaward approaches and the waters in the Arctic archipelago. We also work with other government departments that contract aircraft to conduct surveillance and patrol missions. We pair up with them and make use of those aircraft to conduct surveillance.
As I said, we have, again with our partnership with the United States.... One of our strengths in Canada is our expertise in space. We make use of space extensively to assist in the surveillance, particularly on the maritime side of who is in our waters. The navy, on the Atlantic and Pacific approaches to Canada, has a very good picture of what we call marine domain awareness. That has a high level of fidelity, in terms of what ships are in our waters and where they're going.
It's a difficult challenge based on the size of the space that we have to look at, but we do harness all of our resources, and we work with all of our partner agencies in government to maximize the resources they're employing to build the very best picture of what's going on around our territory.
