Naval Air Base San Pedro, NAS Terminal Island was a US Navy World War II 410-acre airfield on Terminal Island in San Pedro, California part of the City of Los Angeles.

Allen Field was built in 1927 by filling with sand the Port of Los Angeles and enlarging Terminal Island.

A Naval Air Reserve Training Facility was built next to Allen Field in 1927 and used the runway - ramp.

To facilitate delivery of these aircraft, the U.S. Navy established the Naval Air Ferry Command (NAFC) (VRF-3) in 1943.

Due to a shortage to servicemen during the war, a unit of WAVES (Women Accepted for Volunteer Emergency Service) was stationed at the base.
