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 Army Air Forces
By the end of World War II, the USAAF had created 16 numbered air forces ("First" through "Fifteenth" and "Twentieth") distributed worldwide to prosecute the war, plus a general air force within the continental United States to support the whole and provide air defense. The latter was formally organized as the Continental Air Forces and activated on 15 December 1944, although it did not formally take jurisdiction of its component air forces until the end of the war in Europe.
