Background

The ITT 465L Strategic Air Command Control System (SACCS) with its IBM AN/FSQ-31 SAC Data Processing Systems attained operational capability on January 1, 1968; and its gradual replacement began on October 6, 1975, when the SACCS original IBM 4020 Military Computers were replaced by Honeywell 6080 computers (remaining FSQ-31 components were entirely decommissioned in November.)[ citation needed ] The Strategic Air Command Digital Information Network was deployed to replace SACCS' "Data Transmission Subsystem and part of the Data Display Subsystem", [2] 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 [3] (i.e., either a HUTE rack or MBCP rack). [4] On February 20, 1987, "SAC declared initial operational capability for the SAC Digital Network when [it] operated successfully between the Headquarters SAC Command Center and the 55th Strategic Reconnaissance Wing Command Post, both located at Offutt AFB, Nebraska, and the 351st Strategic Missile Wing Command Post at Whiteman AFB, Missouri." [3] SACDIN eventually "linked 135 locations and permitted two-way message communications with ICBM launch control centers for the first time," [3] and the Ground Wave Emergency Network communication system had a Final Environmental Impact Statement issued in September 1987. [5]

SAC Automated Command and Control System

In 1990 when the 465L System had been entirely replaced by the "SAC Auto Cmd/Ctl Sys" [6] for several years, the former SAC C2 system continued using that name as part (except for the SACCS Data Processing System) of "USSTRATCOM Command and Control" (PE 0101316F). [7] By 1995, the "emergency war order (EWO) communication systems consist[ed] of the primary alert system (PAS), SAC digital network (SACDIN), Survivable Low Frequency Communications System (SLFCS), Air Force Satellite Communications System (AFSATCOM), [ICBM] Super High Frequency Satellite Terminal (ISST) and [UHF] voice radio communication systems" [4] The USSTRATCOM SACCS was redesignated[ when? ] Strategic Automated Command and Control System with the same acronym on tbd\ [ specify ] and by 2011, the Minimum Essential Emergency Communications Network was being modernized in the Nuclear Command and Control System. [8] 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." [9]

Age of system and planned replacement

A Government Accountability Office report on aging and outdated "legacy systems" used by the federal government published in 2016 noted that the SACCS was one of the oldest federal IT investments, running on 1970s-era IBM Series/1 software and 8-inch floppy disks. [10] The report noted that the Department of Defense "plans to update its data storage solutions, port expansion processors, portable terminals, and desktop terminals by the end of fiscal year 2017."

Semi-Automatic Ground Environment Historic US military computer network

The Semi-Automatic Ground Environment (SAGE) was a system of large computers and associated networking equipment that coordinated data from many radar sites and processed it to produce a single unified image of the airspace over a wide area. SAGE directed and controlled the NORAD response to a possible Soviet air attack, operating in this role from the late 1950s into the 1980s. Its enormous computers and huge displays remain a part of cold war lore, and after decommissioning were common props in movies such as Dr. Strangelove and Colossus, and on science fiction TV series such as The Time Tunnel.

Missile launch control center

A launch control center (LCC), in the United States, is the main control facility for intercontinental ballistic missiles (ICBMs). A launch control center monitors and controls missile launch facilities. From a launch control center, the missile combat crew can monitor the complex, launch the missile, or relax in the living quarters. The LCC is designed to provide maximum protection for the missile combat crew and equipment vital to missile launch. Missile silos are common across the midwestern United States, and over 450 missiles remain in US Air Force (USAF) service.

Boeing EC-135 Command and control aircraft by Boeing

The Boeing EC-135 is a retired family of command and control aircraft derived from the Boeing C-135 Stratolifter. During the Cold War, the EC-135 was best known for being modified to perform the Looking Glass mission where one EC-135 was always airborne 24 hours a day to serve as flying command post for the Strategic Air Command in the event of nuclear war. Various other EC-135 aircraft sat on airborne and ground alert throughout the Cold War, with the last EC-135C being retired in 1998. The EC-135N variant served as the tracking aircraft for the Apollo program.

Operation Looking Glass American command and control center

Looking Glass is the code name for an airborne command and control center operated by the United States. In more recent years it has been more officially referred to as the ABNCP. It provides command and control of U.S. nuclear forces in the event that ground-based command centers have been destroyed or otherwise rendered inoperable. In such an event, the general officer aboard the Looking Glass serves as the Airborne Emergency Action Officer (AEAO) and by law assumes the authority of the National Command Authority and could command execution of nuclear attacks. The AEAO is supported by a battle staff of approximately 20 people, with another dozen responsible for the operation of the aircraft systems. The name Looking Glass, which is another name for a mirror, was chosen for the Airborne Command Post because the mission operates in parallel with the underground command post at Offutt Air Force Base.
