Command Data Buffer

Last updated

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.

United States Air Force Air and space warfare branch of the United States Armed Forces

The United States Air Force (USAF) is the aerial and space warfare service branch of the United States Armed Forces. It is one of the five branches of the United States Armed Forces, and one of the seven American uniformed services. Initially formed as a part of the United States Army on 1 August 1907, the USAF was established as a separate branch of the U.S. Armed Forces on 18 September 1947 with the passing of the National Security Act of 1947. It is the youngest branch of the U.S. Armed Forces, and the fourth in order of precedence. The USAF is the largest and most technologically advanced air force in the world. The Air Force articulates its core missions as air and space superiority, global integrated intelligence, surveillance, and reconnaissance, rapid global mobility, global strike, and command and control.

LGM-30 Minuteman 1961 family of intercontinental ballistic missiles of the United States Air Force

The LGM-30 Minuteman is a U.S. land-based intercontinental ballistic missile (ICBM), in service with the Air Force Global Strike Command. As of 2018, the LGM-30G Minuteman III version is the only land-based ICBM in service in the United States.

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. [1]

The Improved Launch Control System was a system used by the United States Air Force's Minuteman II intercontinental ballistic missile force. The system was a method to transfer targeting information from a Minuteman launch control center to an individual missile by communications lines. Prior to the Improved Launch Control System, new missile guidance had to be loaded at the launch facility; the process usually took hours.

Phaseout

CDB was replaced in the late 1990s by the Rapid Execution and Combat Targeting system, currently in use by United States ICBM forces. [2]

Rapid Execution and Combat Targeting System

The United States Air Force's Rapid Execution and Combat Targeting System (REACT) is a modification of the LGM-30 Minuteman launch control centers (LCC's) that provides continual monitoring and rapid retargeting of Minuteman ICBMs. It integrates communication systems and weapon systems into a single console.

LGM-118 Peacekeeper former land-based ICBM deployed by the United States

The LGM-118 Peacekeeper, also known as the MX missile, was a land-based ICBM deployed by the United States starting in 1986. The Peacekeeper was a MIRV missile that could carry up to 10 re-entry vehicles, each armed with a 300-kiloton W87 warhead in a Mk.21 reentry vehicle (RV). A total of 50 missiles were deployed starting in 1986, after a long and contentious development program that traced its roots into the 1960s.

The 351st Operations Group is an inactive unit of the United States Air Force. Its last assignment was with the 351st Missile Wing at Whiteman Air Force Base, Missouri. It was inactivated on 31 July 1995.

Missile launch control center type of facility in the United States

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.

The mission of the 625th Strategic Operations Squadron (STOS) is to execute and support global strike through continuous, rapid, accurate and survivable nuclear operations. The 625th STOS has five flights that play different roles in this mission. The Latin motto of the 625th STOS is Si vis pacem para bellum, which means, "If you wish for peace, prepare for war."

Airborne Launch Control System US Strategic Command platform for survivable launch control system for ballistic missile force

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 weapon system is located onboard 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.

This is a chronology of the LGM-30 Minuteman intercontinental ballistic missile, acquisition and operational.

Airborne Launch Control Center US Strategic forces charged with maintaining survivable launch control system for ballistic missile force

Airborne Launch Control Centers provide a survivable launch capability for the United States Air Force's LGM-30 Minuteman Intercontinental Ballistic Missile (ICBM) force by utilizing the Airborne Launch Control System (ALCS) onboard which is operated by an airborne missileer crew. Historically, from 1967–1998, the ALCC mission was performed by United States Air Force Boeing EC-135 command post aircraft. This included EC-135A, EC-135C, EC-135G, and EC-135L aircraft.

A missile combat crew (MCC), is a team of highly trained specialists, often called Missileers, manning Intermediate Range and Intercontinental ballistic missile systems. In the United States, men and women, officially coded as Nuclear and Missile Operations Officers, of the United States Air Force, operate underground missile systems at launch control centers located throughout the country. There are also a select few missileers that have the chance to become part of a Missile Combat Crew-Airborne (MCC-A) operating the Airborne Launch Control System which provides a survivable launch capability for the Minuteman ICBM force. Crew size varied among the different missile systems, but the number was always greater than one, to abide by USSTRATCOM's Two-man rule for positive control of nuclear weapons.

Simulated Electronic Launch Minuteman (SELM) is a method used by the United States Air Force to verify the reliability of the LGM-30 Minuteman intercontinental ballistic missile. SELM replaces key components at the Launch Control Center to allow a physical "keyturn" by missile combat crew members. This test allows end-to-end verification in the ICBM launch process.

Simulated Electronic Launch Peacekeeper (SELP) was a method used by the United States Air Force to verify the reliability of the LGM-118A Peacekeeper intercontinental ballistic missile.
