In 1935 the RCAF constructed a landing field on a section of the Canadian Army's Currie Barracks located in southwest Calgary. The airfield was known as Currie Field or the Calgary Military Airport. In 1938, the aerodrome was home to two RCAF squadrons: No. 3 (Bomber) Squadron with the Westland Wapiti and No. 1 (Fighter) Squadron with the Armstrong Whitworth Siskin and later, the Hawker Hurricane. No. 1 (F) Squadron was renumbered to 401 Squadron when it was posted overseas for combat duty. During the Second World War, the British Commonwealth Air Training Plan (BCATP) established "No. 3 Service Flying Training School" (SFTS) at the airfield. Aircraft flown at this school were Avro Ansons and Cessna Cranes. No. 3 SFTS closed on September 28, 1945.
