Definitely.
First of all, NORAD has a binational structure, which means it is equally responsible to and made up of personnel from the United States and Canada. In fact, it's the world's only binational command structure. It employs a layered defence network of satellites, ground-based radars, airborne radar and fighter aircraft to track and identify aircraft and inform appropriate actions.
In Yukon, for example, NORAD detected the object and launched Canadian and U.S. fighter aircraft to investigate. At the direction of the Prime Minister, as I mentioned, the decision was made to take down the object. This was the first time NORAD had ever downed an aerial object in Canada.
We recognize the need to continue to improve in this area in terms of decision-making. That's why we're putting on the table almost $40 billion to modernize NORAD and continental defence. Going forward, NORAD will continue to exercise its mission exactly as it has done in the past. If an unknown object enters U.S. or Canadian airspace, it will be assessed; it will be identified as to whether it's a threat. If it's not a kinetic military threat, further discussion across government will occur to determine whether it poses a risk to national security, safety of flight, or people on the ground.
I will say that there are additional actions that we are going to be taking. NORAD will continue to have battle rhythm drills, but it will refine these battle rhythm drills to include streamlining the reporting of unidentified objects to improve timely communication on such objects. There will be further efficiencies—
