Ground-Based Midcourse Defense
Ground-Based Midcourse Defense (GMD) is the United States' anti-ballistic missile system for intercepting incoming warheads in space, during the midcourse phase of ballistic trajectory flight. It is a major component of the American missile defense strategy to counter ballistic missiles, including intercontinental ballistic missiles (ICBMs) carrying nuclear, chemical, biological or conventional warheads. The system is deployed in military bases in the states of Alaska and California; in 2018 comprising 44 interceptors and spanning 15 time zones with sensors on land, at sea, and in orbit. In 2019, a missile defense review requested that 20 additional ground-based interceptors be based in Alaska. GMD is administered by the U.S. Missile Defense Agency (MDA), while the operational control and execution is provided by the U.S. Army, and support functions are provided by the U.S. Air Force. Previously known as National Missile Defense (NMD), the name was changed in 2002 to different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Missile Defense
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles. Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles. China, France, India, Iran, Israel, Italy, Russia, Taiwan, the United Kingdom and the United States have all developed such air defense systems. Missile defense categories Missile defense can be divided into categories based on various characteristics: type/range of missile intercepted, the trajectory phase where the intercept occurs, and whether intercepted inside or outside the Earth's atmosphere: Type/range of missile intercepted These types/ranges include strategic, theater and tactical. Each entails unique requirements for intercept, and a defensive system capable of intercepting one missile type frequently cannot intercept others. H ...

Command, Control And Communications
Command and control (abbr. C2) is a "set of organizational and technical attributes and processes ... hatemploys human, physical, and information resources to solve problems and accomplish missions" to achieve the goals of an organization or enterprise, according to a 2015 definition by military scientists Marius Vassiliou, David S. Alberts, and Jonathan R. Agre. The term often refers to a military system. Versions of the United States Army ''Field Manual 3-0'' circulated circa 1999 define C2 in a military organization as the exercise of authority and direction by a properly designated commanding officer over assigned and attached forces in the accomplishment of a mission. A 1988 NATO definition is that command and control is the exercise of authority and direction by a properly designated individual over assigned resources in the accomplishment of a common goal. An Australian Defence Force definition, similar to that of NATO, emphasises that C2 is the system empowering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Management
Battle command (BC) is the discipline of visualizing, describing, directing, and leading forces in operations against a hostile, thinking, and adaptive enemy. Battle command applies leadership to translate decision into actions, by synchronizing forces and warfighting functions in time, space, and purpose, to accomplish missions.— — — Battle command refers both to processes triggered by commanders and executed by soldiers and to the system of systems (SoS) that directly enables those processes. Alternate definition FM 100.5 BC is defined as the art of battle decision-making, leading, and motivating soldiers and their organizations into action to accomplish missions. BC includes visualizing the current state and future state, formulating concepts of operations to get from one to the other, and doing so at least cost. Assigning missions, prioritizing and allocating resources, selecting the critical time and place to act, and knowing how and when to make adjustments during ...

Missile Silo
A missile launch facility, also known as an underground missile silo, launch facility (LF), or nuclear silo, is a vertical cylindrical structure constructed underground, for the storage and launching of intercontinental ballistic missiles (ICBMs), intermediate-range ballistic missiles (IRBMs), medium-range ballistic missiles (MRBMs). Similar facilities can be used for anti-ballistic missiles (ABMs). The structures typically have the missile some distance below ground, protected by a large "blast shelter, blast door" on top. They are usually connected, physically and/or electronically, to a missile launch control center. With the introduction of the Soviet UR-100 and the U.S. LGM-25C Titan II, Titan II missile series, underground silos changed in the 1960s. Both missile series introduced the use of hypergolic propellant, which could be stored in the missiles, allowing for rapid launches. Both countries' liquid-fueled missile systems were moved into underground silos. The introduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbital Sciences
Orbital Sciences Corporation (commonly referred to as Orbital) was an American company specializing in the design, manufacture, and launch of small- and medium- class space and launch vehicle systems for commercial, military and other government customers.

Ground-Based Interceptor
The Ground-Based Interceptor (GBI) is the anti-ballistic missile component of the United States' Ground-Based Midcourse Defense (GMD) system. Description This interceptor is made up of a boost vehicle, constructed by Orbital Sciences Corporation, and an Exoatmospheric Kill Vehicle (EKV), built by Raytheon. Integration of these is performed by Boeing Defense, Space & Security. The three-stage Orbital Boost Vehicle (OBV)Orbital Sciences Ground-based interceptor (GBI (2002) Orbital Boost Vehicle OBV) uses the solid-fuel rocket upper stages of the Taurus launcher. The interceptor version deployed in the U.S. has three stages. A two-stage version was successfully tested in 2010 for use in Europe's NATO missile defence as a backup option to the preferred Aegis System Standard Missile 3. A total of 64 interceptors are planned: 30 interceptors were deployed at the end of 2010 at Fort Greely, Alaska and Vandenberg Air Force Base in California, with 14 additional missiles deployed by ...

Exoatmospheric Kill Vehicle
The Exoatmospheric Kill Vehicle (EKV) is the Raytheon-manufactured interceptor component with subcontractor Aerojet of the U.S. Ground-Based Midcourse Defense (GMD), part of the larger National Missile Defense system. The EKV is boosted to an intercept trajectory by a boost vehicle (missile), where it separates from the boost vehicle and autonomously collides with an incoming warhead. The EKV is launched by the Ground-Based Interceptor (GBI) missile, the launch vehicle of the GMD system. The EKV's own rockets and fuel are for corrections in the trajectory, not for further acceleration. The successor to the EKV, known as the Redesigned Kill Vehicle (RKV), was scheduled to debut in 2025. The RKV program, headed by Boeing and lead subcontractor Raytheon, was canceled by the Department of Defense on August 21, 2019. Earlier in the year, the Pentagon had issued a stop work order on the project following a design review deferment in December 2018 due to the failure of critical compon ...
