George Air Force Base was a United States Air Force base located within the city limits, 8 miles northwest, of central Victorville, California, about 75 miles northeast of Los Angeles, California. Established by the United States Army Air Corps as an Advanced Flying School in June 1941, it was closed at the end of World War II. It was again activated as a training base by the United States Air Force with the outbreak of the Korean War in November 1950. It remained a training base throughout the Cold War and in the immediate post-Cold War period, primarily for the Tactical Air Command (TAC) and later the Air Combat Command (ACC), training USAF, NATO and other Allied pilots and weapon systems officers in front-line fighter aircraft until being closed in 1993.
