The Royal Canadian Air Force (RCAF) (French: Aviation Royale Canadienne (ARC)), formerly Canadian Forces Air Command, is one of three environmental commands of the Canadian Forces. Commanded by Lieutenant-General André Deschamps, Chief of the Air Staff, the RCAF has 14,500 Regular Force and 2,600 Primary Reserve airmen and airwomen, supported by 2,500 civilians.

The Royal Canadian Air Force is responsible for all aircraft operations of the Canadian Forces, enforcing the security of Canada's airspace and providing aircraft to support the missions of Royal Canadian Navy and Canadian Army. The RCAF is a partner with the United States Air Force in protecting continental airspace under the North American Aerospace Defence Command (NORAD). The RCAF also provides all primary air resources to the National Search and Rescue Program.

The RCAF, an independent service until 1968, developed from the Canadian Air Force (CAF), which was formed in 1920. The CAF was incorporated into the Department of National Defence in 1923 and granted royal sanction in 1924 by King George V.
