No. 3 squadron of the Royal Australian Air Force became operational in Egypt on 3rd November 1940.
During the next four and a half years, 3 Squadron became one of the most active squadrons in the RAAF, quickly becoming a jack-of-all-trades. In addition to the conventional reconnaissance and ground attack roles of an army co-operation squadron, it defended ground forces and bombers from enemy aircraft, and conducted strikes against enemy shipping.
