5th Reconnaissance Squadron
Following World War II, the National Security Act of 1947 established the U.S. Air Force as a sister service of the Army and Navy. The concurrent establishment of major commands within the Air Force brought wholesale realignments, including creating new wings with subordinate groups and squadrons. The Air Force established the 9th Strategic Reconnaissance Wing on 25 April 1949 and activated it on 1 May. The Air Force also activated and redesignated the 9th Bomb Group and its subordinate squadrons, making them the 9th Reconnaissance Group, and the 1st, 5th and 99th Reconnaissance Squadrons. The 5th Reconnaissance Squadron's new home was Fairfield-Suisan (later Travis) AFB, California. For the next 11 months, squadron crewmembers flew RB-29s on visual, photographic, electronic, and weather reconnaissance missions.
Idaho Air National Guard
18 September 1947, however, is considered the Idaho Air National Guard's official birth concurrent with the establishment of the United States Air Force as a separate branch of the United States military under the National Security Act. The initial mission of the Idaho ANG was the air defense of the state. On 1 July 1955 the 190th Fighter-Interceptor Squadron was authorized to expand to a group level, and the 124th Fighter Group (Air Defense) was allotted by the National Guard Bureau, extended federal recognition and activated.
