The McChord SAGE Direction Center was one of the six Direction Centers designated as a SAGE Regional Control Center (RCC) in 1966 and it remained operational, still using the vacuum tube FSQ-7 computers, until deactivated on 24 Oct 1983. McChord JSS ROCCWith the closure of the McChord SAGE Direction Center in 1983, the adjacent former SAGE Combat Center was fitted out as a JSS System Regional Operations Control Center (ROCC). The equipment employed was the new FYQ-93 computer system that provided 18+ configurable weapons system consoles and could accept input directly from some 20 JSS System radar sites and other sensor systems. This same system was also in place at the Griffiss Eastern Air Defense Sector and controlled the east coast airspace during the 911 attack. 
During the life of the FYQ-93 at McChord, the name of the command post changed several times, and the area of responsibility grew from just the northwest to the west coast and then in January 1995 to some 1.9 million square miles, about 63% of the CONUS.
