Originally built as a blimp base in 1942 as Santa Ana Naval Air Station.
Following the end of World War II, the Santa Ana NAS was decommissioned by the Navy in 1949. It was then transferred to the Marine Corps in 1951, and was renamed Marine Corps Air Facility Santa Ana by 1965. It was later renamed Marine Corps Air Station Tustin.
