Sir, thank you for your question.
RADARSAT-2 is really about imaging objects on the surface. In that respect, it is not an effective surveillance mechanism for submarines that are transiting underwater or under ice. Having said that, RADARSAT-2 is but one of a large number of sources of information that we base this on. What RADARSAT-2 enables us to do is focus our observation in specific areas of the north in response to other information that tells us we should be looking carefully at what's going on there. I guess that's what I would say in response to your question.
The MSOCs are really information exchange centres, yes, but they allow us to bring all sources of information together, not just military information but information from across government, so that we have all the information we hold on what is going on in a maritime domain and can make sense of it. Vessel reports, radar data, reports from vessels we have and aircraft we have on patrol, and that type of thing are all brought together, with a single understanding of what's happening in our maritime domain.
