Air Defence Command (Canada)

Air Defence Command was a command of the Royal Canadian Air Force and later the Canadian Armed Forces, active from 1951 to seemingly 1975.

Originally, post-war plans called for air defence to be the responsibility of reserve, auxiliary squadrons only. Vampire jet fighters and older P-51 Mustangs were earmarked for these squadrons. With the rise of the "Iron Curtain" and the increasing tension in Europe, a change was seen as necessary and regular, full-time squadrons became the force's frontline.
