ITT 465L Strategic Air Command Control System

System Development Corporation (SDC) also built a Simulation Facility (SIMFAC) in Paramus, New Jersey to model the SAC Command Post using "Command/Control personnel stations, capabilities to produce simulated SACCS hardware printouts…wall displays [and] a soundproof observation deck [booth] in which SIMFAC personnel perform actions necessary to simulate all external occurrences starting from an Intelligence buildup to changes in threat responses"[2]--the 50 ft × 35 ft (15 m × 11 m) "isolation booth" was completed in 1962 by International Electric Corporation.

[7] In September 1960 the "installation of a SAC display warning system" included 3 consoles (e.g., BMEWS Display Information Processor (DIP) in the Offutt bunker[7]: 218  and on 7 December I960, the 465L Program was cut to ""a most austere approach"[7] (an austere air defense sector was also established for NORAD, which soon planned a smaller BUIC control system.)

[14] On January 1, 1968, the SACCS attained operational capability[22] (maintenance at Offutt and March were by the respective 55th Strategic and 33rd[23] Communications Squadrons.)

)[30] Instead of SATIN IV, a restructured plan deployed the Strategic Air Command Digital Information Network to replace SACCS "Data Transmission Subsystem and part of the Data Display Subsystem",[31] e.g., on November 5, 1986, "Martin Marietta Corporation technicians began installing SAC Digital Network (SACDIN) equipment in 91st Strategic Missile Wing missile launch control centers[32] (i.e., either a HUTE rack or MBCP rack).

"[32] SACDIN eventually "linked 135 locations and permitted two-way message communications with ICBM launch control centers for the first time,"[32] and the Ground Wave Emergency Network communication system had a Final Environmental Impact Statement issued in September 1987.

[37] By February 2012, USSTRATCOM was using the Integrated Strategic Planning and Analysis Network (ISPAN), and the USSTRATCOM Replacement Facility Fit-Out (PE 0303255F) was to "include secure HEMP-Shielded Command and Control Center, mainframe computer data centers, multiple 24/7 mission operations centers, storage and maintenance areas, labs/workrooms, back-up generators, Uninterruptible Power Source, Technical Control Facility, Fiber Ring, [with funding] beginning in FY13.

At the Offutt AFB nuclear bunker and at March AFB ; SACCS had 3 AN/FSQ-31 systems each with a Data Processing Central (DPC), Data Display System (DDS), and Data Transmission Subsystem (DTS) [ 1 ] ( Barksdale AFB didn't have a DPC.) The DCS consisted of an Encryption/Decryption Subsystem, High Speed Data Transmission Equipment (Modems), and an Electronic Data Transmission Control Center (EDTCC) with secure voice units and Technical Control Consoles (TCCs)--SACCS "voice transmission [was] by patching 4-wire telephone terminating equipment on the circuit at each end. [ 1 ] NORAD 's 1963 Chidlaw Building Combined Operations Center, then Cheyenne Mountain Complex in 1966 (top left), received SAC data (e.g., to allow relay of messages through northern NORAD radar stations for recalling SAC bombers.)

In 1965, RCCs were at 13 "operational base command posts" (duplexed from different EDTCCs except for 4 RCCs with "short order sites"), and SRCCs were at 2 "missile site alternate command posts"—RCCs/SRCCs had a "Fault and Facility Control Panel.". One Offutt EDTCC communicated with 1 SRCC and 6 RCCs (with 2 circuits to the 1 local RCC), while the other Offutt EDTCC only had circuits to 4 RCCs (2 bomber, 2 ICBM). At the Numbered Air Force bases, circuits from one EDTCC were to 7 RCCs, and the other connected to 5 RCCs and 1 missile SRCC. [ 1 ]
