Two Australian fighter squadrons also took part in the fighting in North Africa. No. 239 Wing, a Curtiss P-40-equipped unit in the Desert Air Force, was dominated by Australians, in the form of two RAAF squadrons—No. 3 Squadron and No. 450 Squadron—and numerous individual Australians served in RAF squadrons. These two squadrons differed from the other RAAF squadrons in the Mediterranean in that they were made up of predominantly Australian ground-staff and pilots; the other RAAF units had ground crews made up of mostly British RAF personnel.
