US Ambassador to Canada Pete Hoekstra describes the current defence relationship between the two countries as “awesome,” but stressed military interventions by the US military into Canadian airspace would increase if Canada does not increase its purchase of Lockheed Martin F-35s beyond the 16 currently on order.
The North American Air Defence Command (NORAD) is a decades-old partnership between Canada and the US which tracks inbound threats and scrambles armed jets to intercept where appropriate.
