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.
Air National Guard
Being "local" ground forces affiliated with the Army, militias were considered state-centric/territorial-centric in nature, this versus naval forces, which were considered wholly activities of the federal government. This distinction accounts for why there are no National Guard components in the U.S. Navy, U.S. Marine Corps or U.S. Coast Guard. Because the present day U.S. Air Force evolved from the U.S. Army, it was only natural that a separate Air National Guard would be established with the divestiture of the former U.S. Army Air Forces and its establishment as a separate and independent U.S. Air Force in 1947.
