Primary Alerting System
The Primary Alerting System (PAS), was a network of land-line connections used by the Strategic Air Command ( SAC) for command and control of its nuclear forces. PAS provided immediate and simultaneous voice communications to all ( SAC) unit command posts and missile launch control facilities. PAS reached each Command Post by two geographically diversified circuits; one circuit, commonly called the "front-door" circuit tied the unit directly to Headquarters ( SAC); the other, or "back-door" circuit provided a link to the parent Numbered Air Force.

Minimum Essential Emergency Communications Network
The Minimum Essential Emergency Communications Network (MEECN) is a network of systems providing uninterrupted communications throughout the pre-, trans-, and post-nuclear warfare environment. At minimum, MEECN is designed to provide a one-way flow of information to activate nuclear forces during severe jamming and a post-nuclear environment. Components As of 1994, MEECN consists of various programs: Miniature Receive Terminals (MRTs) for nuclear bombers, High Power Transmit Sets (HPTS) for E-4B aircraft, Dual Frequency MEECN receivers (DFMRs) for ICBM Launch Control Centers. Ground Element MEECN System (GEMS) The GEMS program, short for Ground Element Minimum Essential Emergency Communications Network, is intended to replace deprecated communications facilities. This system features improved infrastructure for alerting aircrew, and maintaining communications in the event of nuclear conflict. Notable elements include updated Extremely High Frequency (EHF) communications satellites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Wave Emergency Network
The Ground Wave Emergency Network (GWEN) was a command and control communications system intended for use by the United States government to facilitate military communications before, during and after a nuclear war. Specifically, the GWEN network was intended to survive the effects of an electromagnetic pulse from a high-altitude nuclear explosion and ensure that the United States President or their survivors could issue a launch order to Strategic Air Command bombers by radio. The New York Times, 12 September 1988 AN/URC-117 was the system's identifier, which signified various radio comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airborne Launch Control System
The Airborne Launch Control System (ALCS) provides a survivable launch capability for the United States Air Force's LGM-30G Minuteman III intercontinental ballistic missile (ICBM) force. The ALCS is operated by airborne missileers from Air Force Global Strike Command's (AFGSC) 625th Strategic Operations Squadron (STOS) and United States Strategic Command (USSTRATCOM). The system is located on board the United States Navy's E-6B Mercury, which serves as USSTRATCOM's " Looking Glass" Airborne Command Post (ABNCP). The ALCS crew is integrated into the ABNCP battle staff and is on alert around the clock. Overview In the mid-1960s, United States civilian and military leadership became concerned about the possibility of a decapitating attack from the Soviets, destroying any land-based communication links to the nuclear forces of the Strategic Air Command. One solution to the communication problem was placing radio equipment on board an aircraft, and allow it to fly over the United State ...

Post Attack Command And Control System
The Post Attack Command and Control System (PACCS) was a network of communication sites (both ground and airborne) for use before, during and after a nuclear attack on the United States. PACCS was designed to ensure that National Command Authority would retain exclusive and complete control over US nuclear weapons. Among other components, it included Strategic Air Command assets such as the Looking Glass aircraft and mission, and various hardened command and control facilities. The belief by the Soviet Union in the reliability of PACCS was a crucial component of the US mutual assured destruction doctrine, ensuring a long-term stalemate. History The Strategic Air Command headquarters staff, under the direction of General Thomas S. Power assessed the feasibility of placing a continuous command and control element in an airborne mode. The purpose of such a system would be to use the aircraft as a platform for specially installed communications equipment to ensure delivery of comma ...

Command Data Buffer
Command Data Buffer (CDB) was a system used by the United States Air Force's Minuteman ICBM force. CDB was a method to transfer targeting information from a Minuteman Launch Control Center to an individual missile by communications lines. Prior to CDB, new missile guidance would have to be physically loaded at the launch facility; the process usually took hours. History The surviving remnant of the Minuteman Command Control System (MICCS), CDB permitted the rapid, remote, retargeting of the Minuteman III fleet. CDB was operational at all Minuteman III wings by 15 Aug 1977. Minuteman II wings had a similar install, designated Improved Launch Control System, providing the older system the potential for remote retargeting. Phaseout CDB was replaced in the late 1990s by the Rapid Execution and Combat Targeting system, currently in use by United States ICBM forces.

Survivable Low Frequency Communications System
The AN/FRC-117 Survivable Low Frequency Communications System (SLFCS) was a communications system designed to be able to operate, albeit at low data transfer rates, during and after a nuclear attack. The system used both very low frequency (VLF), and low frequency (LF) radio bands. Mission SLFCS was used for United States nuclear forces' command and control communications for Emergency Action Message dissemination and force direction. Single channel, receive only capability was provided at ICBM launch control centers. The single channel operated between 14 kHz and 60 kHz to receive commands from remotely located Combat Operations Center – Transmit/Receive (T/R) sites; this low frequency range is only slightly affected by nuclear blasts. SLFCS' primary advantage was that it would experience minimal radio signal degradation as a result of nuclear detonations. It would be an alternate means of communication during and after detonations, providing a survivable comma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AUTODIN
The Automatic Digital Network System, known as AUTODIN, is a legacy data communications service in the United States Department of Defense. AUTODIN originally consisted of numerous AUTODIN Switching Centers (ASCs) located in the United States and in countries such as England and Japan. Background The design of the system, originally named "ComLogNet", began in 1958 by a team of Western Union, RCA and IBM. The customer was the U.S. Air Force and the system's purpose was to improve the speed and reliability of logistics traffic (spare parts for missiles) between five logistics centers and roughly 350 bases and contractor locations. An implementation contract was awarded in the fall of 1959 to Western Union as prime contractor and system integrator, RCA to build the 5 switching center computers and IBM for the compound terminals which provided for both IBM punched card and Teletype data entry. The first site became operational in 1962. During the implementation the government reali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SAC Automated Command And Control System
The Strategic Automated Command and Control System (SACCS) is a United States Strategic Command command and control system to coordinate the operational functions of United States nuclear forces (ICBMs, nuclear bombers, and SLBMs). 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.) The Strategic Air Command Digital Information Network was deployed to replace SACCS' "Data Transmission Subsystem and part of the Data Display Subsystem", 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 (i.e., either a HUTE rac ...
