No. 4 Service Flying Training School RAAF

No. 4 Service Flying Training School (No. 4 SFTS) was a flying training school of the Royal Australian Air Force (RAAF) during World War II. It was formed in February 1941, and commenced flying the following month. Responsible for intermediate and advanced instruction of pilots under the Empire Air Training Scheme (EATS), the school was based at Geraldton, Western Australia, and operated Avro Anson aircraft. Two reserve squadrons were formed in response to the outbreak of war in the Pacific, though they never saw action. Flying activity was reduced towards the end of 1943, and the school was disbanded in May 1945, having graduated over 1,000 pilots. It re-formed as No. 87 Operational Base Unit, which was renamed Care and Maintenance Unit (CMU) Geraldton in May 1946. CMU Geraldton was disbanded in September 1947.
