During World War II, the Royal Australian Air Force established a Bombing and Gunnery School (2BAGS) at Port Pirie in June 1941. The role of these schools was to teach bombing and aerial gunnery in accordance with the standard Royal Air Force syllabus. During the course of the war, 2 Operational Training Unit (2OTU) was formed at Port Pirie on 6 April 1942 and later 2BAGS was formally re-designated as 3 Aerial Observers School (3AOS) on 9 December 1943.
Over the course of the schools’ existence, 22 RAAF airman died during training operations. A commemorative service will be held to honour their memories and recognise their sacrifice.
