Mr. Chair, I thank the member for the question.
The possibilities are endless. In terms of sensors and effectors, fighter aircraft or tankers and so forth, we have needs everywhere.
We do the work with the tools we've been given, and we send a list of our requirements to the Canadian and U.S. governments every year. As I mentioned earlier, those needs change as the threat changes.
After 9/11, we had to adapt to a new internal threat, that of terrorist groups using commercial aircraft. We're currently transitioning to be able to detect cruise missiles and respond to the threat, as I mentioned earlier.
As part of the modernization of NORAD, the Canadian government is going to give us additional tools that will improve our ability to respond to the mission.
I mentioned the Canadian government, but the U.S. government also announced support in its most recent budget for the purchase of four over-the-horizon radars, similar to the ones Canada will procure after NORAD modernization.
We continue to communicate our needs to both governments to ensure we're able to respond to a current or future threat.
