Early administration and training was carried out by RAF officers and other personnel, who were seconded to the new Royal Ceylon Air Force or RCyAF. The first aircraft of the RCyAF were de Havilland Canada DHC-1 Chipmunks, used as basic trainers. These were followed by Boulton Paul Balliol T.Mk.2s and Airspeed Oxford Mk.1s for advanced training of pilots and aircrew along with de Havilland Doves and de Havilland Herons for transport use, all provided by the British. The closure of British bases in Ceylon in 1956 saw the air force take over former RAF bases; Katunayake and China Bay became RCyAF operational stations while auxiliary functions were carried out at Diyatalawa and Ekala.
