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.
Nineteenth Air Force
The Nineteenth Air Force was inactivated in July 1973, as part of the economies enacted after the end of the Vietnam War. On 4 August 1998, the Chief of Staff of the United States Air Force (CSAF), General Michael E. Ryan, and the Acting Secretary of the Air Force (SECAF), F. Whitten Peters, announced their plans to implement a major change in the structure of the Air Force. They proposed to divide the USAF’s combat strength and the elements directly supporting it into ten Aerospace Expeditionary Forces (AEFs). Although the EAF concept was a major step in recasting the operations, outlook, and culture of the USAF, it sprang from the performance of missions traditionally performed by the Air Force — the timely response of land-based air power to the needs of the nation.
