Det 2 is a tenant unit under Canada's 22 Wing. The wing provides surveillance, identification, control, and warning for the aerospace defense of Canada and North America.
Radar information received via satellite from the North Warning System across the Canadian Arctic, coastal radars on the east and west coasts of Canada, and airborne warning and control system aircraft is collected and analyzed by operators on site. These operators are experts in surveillance and identification of all air traffic approaching North America, which amounts to some 200,000 flights per year.
All aircraft penetrating this radar coverage are detected and identified by the personnel of 21 Aerospace Control and Warning Squadron, who are always on guard--24 hours per day, 7 days per week. Unidentified aircraft, aircraft in distress, or aircraft suspected of conducting illegal activities may be intercepted by Canadian CF-18 fighters.
Critical information on air sovereignty events is forwarded to the North American Aerospace Defense Command (NORAD) at Peterson Air Force Base, Colorado, where it is in turn passed on to the command authorities--the President of the United States and the Prime Minister of Canada--to decide on the appropriate responses.
Training of the personnel who perform the air sovereignty mission is done by 51 AC&W (Operational Training) Squadron, an integral unit of 22 Wing.
Due to this binational nature of the NORAD agreement, Det 2 provides US personnel to support the mission of the Canadian Air Defense Sector (CADS).
