List of Royal Canadian Air Force squadrons
The Royal Canadian Air Force existed from 1924 to 1968, later designated Canadian Forces Air Command under the Canadian Forces, and then renamed to its original historic name of Royal Canadian Air Force in 2011. These are the squadrons that have served with Canada's air force since 1924.
The 100-series squadrons
Established in Canada in the 1930s most of these units were either disbanded or reassigned a 400 series number for overseas service.
The 400-series squadrons
During the Second World War, the British Commonwealth Air Training Plan set out co-operation between the various British Commonwealth air forces. Under Article XV of the plan, RCAF squadrons were attached to and/or formed within British RAF operational formations. These squadrons were known as 'Article XV squadrons'. To avoid confusion with squadron numbers of other Commonwealth squadrons, RCAF units were assigned squadron numbers from 400-449. Not all squadrons up No. 449 were formed, however. This squadron series continued through the post-war years, and the majority of current Royal Canadian Air Force operational squadrons are still numbered in the 400s due to their legacy as wartime units. For this historical reason current squadrons are listed here with their original RCAF names.
The 600-series squadrons
During the Second World War pilots who served in the 600-series RCAF squadrons were recruited from the Royal Canadian Artillery in England and Italy, and trained to fly at 22 E.F.T.S. Cambridge (England), completing their operational flying training at 43 O.T.U. (RAF Andover). Observers were trained at Larkhill (England); these were selected 'Other Ranks' from the Royal Canadian Air Force and Royal Canadian Artillery. The three Canadian 'Air Observation Post' squadrons operated under the command of 70 Group, RAF Fighter Command; the first two squadrons saw action while serving with 84 Group, Second Tactical Air Force.
Subsequent to the Second World War the RCAF expanded their squadron numbers to include 444-450. No. 450 was also a Royal Australian Air Force squadron during the war and the Canadian squadron duplicated the number by error, which was discovered when No. 450 Squadron RCAF was formed in 1968.
