The SOCC employs 27 NORAD contingency suites, and 31 Battle Control System-Fixed (BCS-F) displays. BCS-F fuses data from airborne, ground and naval elements and civil air traffic sensors into an integrated air picture. This allows commanders to monitor the airspace above, beyond and within U.S. and Canadian borders, providing a major component for homeland defense.
It also incorporates a newly developed situational awareness system that gives WADS unprecedented tools and technology to assist state and local responders in dealing with natural disasters. It has the redundant capability to cover the EADS if the call arises.

On 1 April 1966, SEADS was inactivated, as did the other 22 sectors in the country. Most of its assets were assumed by the 25th Air Division. The DC-12 SAGE Direction Center was assigned to the 25th Air Division, remaining in operation until 31 December 1969.

At the end of 2005, the outdated Q-93 radar system was replaced with modernized computer systems which was a major shift in how CONUS is defended since the Q-93 system had been in use since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.
