A SAGE component, a 64 x 64 [4K] magnetic core memory … SAGE direction center. This installation is located at Stewart Air Force Base in New York state. …[Hancock Field] combined direction-combat center was located at Syracuse, New York.[captions of p. 198, 208, & 265 photos] NOTE: Schaffel's history uses the same name as "The Emerging Shield: The Air Defense Ground Environment," Air University Quarterly Review 8, no. 2 (spring 1956).
SAGE—Air Force project 416L—became the pattern for at least twenty-five other major military command-control systems… These were the so-called "Big L" systems [and] included 425L, the NORAD system; 438L, the Air Force Intelligence Data Handling System; and 474L, the Ballistic Missile Early Warning System (BMEWS). … Project 465L, the SAC Control System (SACCS) [with] over a million lines, reached four times the size of the SAGE code and consumed 1,400 man-years of programming; SDC invented a major computer language, JOVIAL, specifically for this project.
A previously referenced AT&T training manual on SAGE/BUIC/AUTOVON phone systems does list all the AUTOVON/SAGE Switching Centers & includes their General Purpose (AUTOVON) NNX, their SAGE NNX, and … For example, Delta, Utah had 890 for AUTOVON, 764 for SAGE

The missile and space surveillance and warning system currently[specify] consists of five systems and a space computational center located in the NORAD Cheyenne Mountain complex. The five systems are: the Ballistic Missile Early Warning System; the Defense Support Program (DSP) formerly called Project 647; the Forward Scatter over the Horizon Radar (440L system); the Sea-Launched Ballistic Missile Warning System; and the Space Detection and Warning System. … 20 April The 425L system portion of the NORAD Cheyenne Mountain Complex (NCMC) became fully operational.

Semi-Automatic Direction Center System, later known as…Semi-Automatic Ground Environment System, in essence, the Lincoln Transition System.
To be more specific, I have in mind something like the BADGE system; in U.S. experience, examples would be SAGE, 412L,[specify] or the NORAD COC … The early development of SAGE was hampered by the fact that the radars were not considered as a part of the system.
The function of the Control Center in solving the air defense problem is to combine, summarize, and display the air battle picture for the supervision of the several sectors within the division. … The typical Control Center (CC) building housing the AN/FSQ-8 Combat Control Central is a 3-story structure of the same type construction as the DC building.(p. 7)

To ensure continuous operation each computer was duplexed; it actually consisted of two machines.
The North Bay SAGE centre is the only one on the continent to be fully "hardened", or constructed underground.

The following paper is a description of the organization and techniques we used at MIT's Lincoln Laboratory in the mid-1950s to produce programs for the SAGE air-defense system. The paper appeared a year before the announcement of SAGE; no mention was made of the specific application other than to indicate that the program was used in a large control system. The programming effort was very large—eventually, close to half a million computer instructions. About one-quarter of these instructions supported actual operational air-defense missions. … In a letter to me on April 23, 1981 … A Lincoln Utility System of service routines containing 40,000 instructions has been prepared … the experience of the Lincoln Laboratory that a system of service programs equal in size to the main system program must be maintained to support preparation, testing, and maintenance of the latter.
