Its mission was to train newly graduated pilots from Training Command in combat tactics and maneuvers before being assigned to their permanent combat unit. Initially assigned to IV Fighter Command, then transferred to III Fighter Command in 1944, being re-equipped with P-51D Mustangs. It took part in air-ground maneuvers and demonstrations, participating in the Louisiana Maneuvers in the summer of 1944 and in similar activities in the US until after V-J Day.

Utah Air National Guard The wartime 407th Fighter Squadron was re-activated and re-designated as the 191st Fighter Squadron, and was allotted to the Utah Air National Guard, on 24 May 1946. It was organized at Salt Lake City Municipal Airport, Utah and was extended federal recognition on 18 November 1946 by the National Guard Bureau. The 191st Fighter Squadron was entitled to the history, honors, and colors of the 407th Fighter Squadron. The squadron was equipped with F-51D Mustangs and was assigned to the Colorado Air National Guard 140th Fighter Group, although it was operationally under the control of the Utah Air National Guard at Salt Lake City. During its early years with the F-51D, the unit earned prominence as one of the Air Force's most respected aerial gunnery competitors. Korean War activation As a result of the Korean War, the 191st Fighter Squadron was federalized and brought to active duty on 1 April 1951 and assigned to the 140th Fighter Wing. The unit was ordered to the new Clovis Air Force Base, New Mexico, which arrived in October 1951. The federalized 140th was a composite organization of activated Air National Guard units, composed of the 191st, the 187th Fighter Squadron (Wyoming ANG) and the 120th Fighter Squadron (Colorado ANG). The 140th and its components were equipped with F-51D Mustangs, and were re-designated as Fighter-Bomber squadrons on 12 April 1951. During their period of federal service, many pilots were sent to Japan and South Korea to reinforce active-duty units,
