There was also a light group, the 3rd Attack Group, equipped with a mixture of Douglas A-20 Havocs and B-25 Mitchells. This group was not just short of aircraft; it was critically short of aircrew as well. To make up the numbers the USAAF turned to the RAAF for help. Australian aircrew were assigned to most of the group's aircraft, serving in every role except aircraft commander. In addition to the RAAF aircrew with the USAAF squadrons, there were RAAF units in the Port Moresby area. No. 30 Squadron RAAF, which had arrived in Port Moresby in September 1942, was equipped with the Bristol Beaufighter. Both the aircraft and the squadron proved adept at low level attacks. Also in the Port Moresby area were the 35th and 49th Fighter Groups, both equipped with Bell P-39, Curtiss P-40 Warhawk and Lockheed P-38 Lightning fighters, but only the last were suitable for long range escort missions.
