Santa Ana Army Air Base (SAAAB) was a World War II-era air base located near Santa Ana, California. The air base was decommissioned in 1946, and part of the land was annexed by Costa Mesa in 1953. The air base was used for basic training, although it did not have planes, hangars or runways. The base was 1,336 acres (5.41 km2), and the main section of the base was located between Baker Street to the north, Harbor Boulevard to the west, Wilson Street on the south, and Newport Boulevard on the east. The land formerly occupied by the air base is today the home of John Wayne Airport, the Orange County Fairgrounds, and Orange Coast College.
