The Canadian Air Force (CAF) was a contingent of two Canadian air force squadrons – one fighter and one bomber – authorized by the British Air Ministry in August 1918 during the close of the First World War. The unit was independent from the Canadian Expeditionary Force and the Royal Air Force (RAF). Both squadrons were stationed in the United Kingdom at Upper Heyford and later, Shoreham-By-Sea, Sussex. All aircraft, equipment and training facilities were provided by Britain. Recruiting, pay and clothing, however, was a Canadian responsibility.
