We have two strategic air-to-air refuellers on standby at all times. They're located in the United States, both on the west coast and the east coast. They are provided for us to use whenever we need them, especially when we have to travel long distances to go north and intercept and take a look at a track of interest. More often than not—because I was also the commander in Winnipeg for the Canadian region—whenever we deployed up north, we would bring RC-130 tactical refuellers to the same location to help out, and when it's available we would use our Airbus as well. However, you will understand that we have been busy in the Forces in the last few years and our tankers have been very useful within the coalition, as they are now. So it depends. If they're available we'll take them. Sometimes they're not available, but we have support from the United States to do our mission.
