In September 1953 the 164th, now designated as a Fighter-Bomber Squadron, received its first jet aircraft, refurbished F-80A Shooting Stars that had been modified and upgraded to F-80C standards. The squadron only operated the Shooting Star for a year when in October 1954 the equipment was changed to F-84E Thunderjets that had returned from wartime duty in Korea. In August 1954, the 164th began standing daytime air defense alert at Mansfield, placing two aircraft at the end of the runway with pilots in the cockpit from one hour before sunrise until one hour after sunset. This ADC alert lasted each and every day until 30 June 1956.
