Southwest Air Defense Sector

Los Angeles Air Defense Sector

The Los Angeles Air Defense Sector (SAGE) (LAADS) was designated by Air Defense Command in February 1959 while NORAD's July 25, 1958, SAGE Geographic Reorganization Plan was being implemented. Assuming control of former ADC Western Air Defense Force units, the sector's region consisted of ADC atmospheric forces (fighter-interceptor and radar units) located in southern California north to Santa Barbara and the southern Central Valley. The Manual Air Direction Center (MDC) was at Norton AFB, California, until the Air Defense Direction Center (DC-17) was completed in 1959 for the Semi Automatic Ground Environment.

On 1 April 1966, LAADS was inactivated, as did the other 22 sectors in the country. Most of its assets were assumed by the 27th Air Division.

Reactivated as the Southwest Air Defense Sector (SWADS) on 1 July 1987 at March AFB, California, in the 26th Air Division; the sector received the 26th AD assets when it became inactive on 30 September 1990. SWADS was responsible for the atmospheric defense of approximately one-fourth of the Continental United States. Its eastern border was at the intersection of the 36th parallel north and 97th meridian west south to the Gulf of Mexico at the 28th parallel north. Its region extended west to include the region south of the 36th parallel north to the Pacific Ocean at the 122nd meridian west. It came under the Continental NORAD Region (CONR) Headquarters at Tyndall AFB, Florida. The Joint Surveillance System Sector Operations Control Center (SOCC) was at March AFB and Air Route Surveillance Radar (ARSR) data from several JSS radar stations and tethered aerostat radar balloons (e.g., Ground Equipment Facility J-31 near Los Angeles).

On 1 January 1995, the SWADS consolidated with the Northwest Air Defense Sector, headquartered at McChord AFB, Washington and the combined command was designated as the Western Air Defense Sector (WADS).
