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 Force Security Forces
On 12 February 1942 the United States adopted the British air defense philosophy. The Army Chief of Staff, Gen. George C. Marshall, approved the allocation of 53,299 African-Americans to the Army Air Forces with the "stipulation that air base defense 'for the number of air bases found necessary' be organized and that 'Negro personnel' be used for this purpose as required." This order formed the Army Air Forces (AAF) air base security battalions in June 1942. Units were deployed throughout the European, Asian and African theaters and designed to defend against local ground attacks. These units were armed with rifles, machine guns and 37mm guns.
