In mid-1942, a number of USAAF 5th Air Force Airacobras serving in the New Guinea theatre (including P-39Ds and P-39Fs) were diverted to the Royal Australian Air Force (RAAF). Fourteen Airacobras (serials A53-1/14) were received at No 2 AP Bankstown on July 27, 1942, and these aircraft subsequently served with Nos 23, 24, 82 and 83 Squadrons. A further five Airacobras arrived in May 1943 (serials were A53-15/19) and three more were received in July 1943 (serials were A53-20/22). The RAAF Airacobras were used exclusively for patrols against Japanese aircraft attempting to attack targets in Australia, and never saw any combat. By November 1943, all the RAAF Airacobras had been returned to the 5th Air Force, with the exception of A53-1, -3, -5 and -8, which had been written off in accidents.
