As the Flying Corps grew, so did the number of wings. The 3rd Wing was established on 1 March 1915 and on 15 April the 5th Wing came into existence. By August that year the 6th Wing had been created and in November 1915 a 7th Wing and 8th Wing had also been stood up. Additional wings continued to be created throughout World War I in line with the incessant demands for air units. The last RFC wing to be created was the 54th Wing in March 1918, just prior to the creation of the RAF.
