History
The air division was activated at Fresno Army Air Base, California as the 4th Ground Air Support Command in September 1942, drawing its cadre from the 15th Bombardment Wing, which was simultaneously inactivated. It was one of five such commands activated that month.

Following the Japanese attack on Pearl Harbor, the command's observation units performed antisubmarine patrols off the Pacific coast. These patrols continued until January 1943.
