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.
United States Air Forces Southern Command
A second permanent army airfield, Albrook Field, opened in 1932 due to France Field becoming too small for the numbers of aircraft being assigned to the Canal Zone, as well as having a poor landing surface; offering no room for expansion, and providing little defense for the Pacific entrance to the Panama Canal. A third airfield, Howard Field was built on the Canal Bruja Point Military Reservation, opening on 1 December 1939. By 1940, a rapid increase in the number of flying squadrons in both the Canal Zone as well as in Panama as a result of the pre–World War II mobilization of the Air Corps warranted a new organization, and the Panama Canal Air Force was created as a major command. After several organizational changes and the establishment of the United States Army Air Forces in 1942, Sixth Air Force became the controlling Air Force command authority for USAAF activities in the Caribbean, as well as in Central and South America. Through all these redesignations it was part of the Caribbean Defense Command, (10 February 1941 – 1 November 1947), which was the senior United States Army headquarters in the Canal Zone. The Caribbean Interceptor Command, was the Air Force component (10 February 1941 – 17 October 1941) of the CIC until being inactivated and replaced by VI Interceptor Command.
