I will start, and General Huddleston might have more to add.
Yes. The idea is that the Canadian contribution to the new layered surveillance system would be an Arctic over-the-horizon radar site near the Canada-U.S. border that would look to the outer reaches of Canadian territory. A second site would be in the High Arctic in Canada that would see up and over the pole. A little bit of residual research and development are required for that High Arctic system, but the plan would be for that to be fielded approximately two years after the lower-latitude system.
Thank you.
