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.
Numbered Air Force
The table below lists current and historical numbered air forces of the US Air Force, their C-NAF designation (if applicable), their current shield and station, and the major command (MAJCOM) to which they are currently assigned. Note that the lineage of some numbered air forces is continued by non-NAF organizations (e.g., the 15th Expeditionary Mobility Task Force continues the lineage of the Fifteenth Air Force). Boldface indicates a NAF or C-NAF that is currently active.
Named Air Forces operate at the same level as Numbered Air Forces. General Headquarters Air Force, the first named air force of the United States Army's air arm, began operations in 1935. The GHQ Air Force became the Air Force Combat Command in 1941. Several of the numbered air forces began as named air forces.
