First of all, we do have a limited air-to-air refuelling capability that we've employed over the years. Canada and the Royal Canadian Air Force have been providing both our tactical tankers, the C-130H tanker as well as the Airbus, which has a multi-role platform as well, to support our operations on a non-persistent basis. For the regular response, we actually rely on tankers provided by the U.S. Air Force.
However, I can tell you that, as part of the NORAD modernization package approved in June of this year, there will be an enhancement to the strategic air-to-air refuelling capabilities of the Royal Canadian Air Force that will enable greater participation and support of our activity. It's going to increase not only our response posture but also our reach in the very wide area of the Canadian Arctic.
