The DC-12 SAGE Direction Center was assigned to the 25th Air Division, remaining in operation until 31 December 1969.

WADS assumed responsibility for the air sovereignty of the western United States from Texas around the west coast and across to North Dakota. Its area of responsibility is approximately 1.9 million square miles, about 63% of the continental United States. On 1 October 1997, the Western Air Defense Sector completed a seamless transition from the active duty Air Force to the Air National Guard. Citizen-soldiers of the Washington Air National Guard are currently guarding America's skies. The

(CONR) has responsibility for the Western Air Defense Sector and Eastern Air Defense Sector. It is headquartered at

, Florida. At the end of 2005, the outdated Q-93 radar system was replaced with modernized computer systems which was a major shift in how CONUS is defended since the Q-93 system had been in use since 1983. Also, in 2005 Western Air Defense Sector assumed responsibility of more airspace shifting from down the center of the US to East of Mississippi totalling roughly 75% of the US airspace. There have been a few system updates since 2005 but only upgrades to the firmware and program versions, not the hardware itself like what happened in 2005.
