Sprint Missile
The Sprint was a two-stage, Solid-propellant rocket, solid-fuel anti-ballistic missile (ABM), armed with a W66 neutron bomb, enhanced-radiation thermonuclear weapon, thermonuclear warhead used by the United States Army from 1975-1976. It was designed to intercept incoming Atmospheric entry, reentry vehicles (RV) after they had descended below an altitude of about , where the thickening air stripped away any decoys or Corner reflector, radar reflectors and exposed the RV to observation by radar. As the RV would be traveling at about , Sprint had to have phenomenal performance to achieve an interception in the few seconds before the RV reached its target. Sprint accelerated at 100g-force, ''g'', reaching a speed of in 5 seconds. Such a high velocity at relatively low altitudes created skin temperatures up to , requiring an ablative shield to dissipate the heat. The high temperature caused a plasma (physics), plasma to form around the missile, requiring extremely powerful radio signa ...

Anti-ballistic Missile
An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles (missile defense). Ballistic missiles are used to deliver nuclear weapon, nuclear, Chemical weapon, chemical, Bioagent, biological, or conventional weapon, conventional warheads in a ballistics, ballistic flight trajectory. The term "anti-ballistic missile" is a generic term conveying a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs). Current counter-ICBM systems There are a limited number of systems worldwide that can intercept intercontinental ballistic missiles: * The Russian A-135 anti-ballistic missile system (renamed in 2017 to A-235) is used for the defense of Moscow. It became operational in 1995 and was preceded by the A-35 anti-ballistic missile system. The system uses ABM-4 Gorgon, Gorgon and Gazelle (missile), Gazelle missiles pre ...

Multiple Independently Targetable Reentry Vehicle
A multiple independently targetable reentry vehicle (MIRV) is an exoatmospheric ballistic missile payload containing several warheads, each capable of being aimed to hit a different target. The concept is almost invariably associated with intercontinental ballistic missiles carrying thermonuclear warheads, even if not strictly being limited to them. By contrast, a unitary warhead is a single warhead on a single missile. An intermediate case is the multiple reentry vehicle (MRV) missile which carries several warheads which are dispersed but not individually aimed. Only the United States, the United Kingdom, France, Russia, China and India are currently confirmed to have deployed MIRV missile systems. Pakistan is developing MIRV missile systems. Israel is suspected to possess or be in the process of developing MIRVs. The first true MIRV design was the Minuteman III, first successfully tested in 1968 and introduced into actual use in 1970. The Minuteman III held three small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Gaither Committee
''Deterrence & Survival in the Nuclear Age'', commonly referred to as the Gaither report, is a report submitted in November 1957 to the United States National Security Council and the United States President, U.S. president concerning strategy to prepare against the perceived threat of a Nuclear warfare, nuclear attack from the Soviet Union. It was prepared by a panel constituted as part of the Science Advisory Committee, at that time part of the Office of Defense Mobilization. The report's common name stems from the panel's first chairman H. Rowan Gaither. He and the group were tasked by President Dwight D. Eisenhower with creating a strategy that would strengthen the US military Missile defense, defensive systems, and better prepare the US for a nuclear attack. The report was largely written by panel members Paul Nitze and George Lincoln. It called for an urgent strengthening of US missile technology, along with offensive and defensive military capabilities. It also called for a f ...

Kwajalein Atoll
Kwajalein Atoll (; Marshallese: ) is part of the Republic of the Marshall Islands (RMI). The southernmost and largest island in the atoll is named Kwajalein Island, which its majority English-speaking residents (about 1,000 mostly U.S. civilian personnel) often use the shortened name, Kwaj . The total land area of the atoll amounts to just over . It lies in the Ralik Chain, southwest of Honolulu, Hawaii. The US Navy has hosted a naval base on Kwajalein Island since World War II. It was the final resting place of the German cruiser '' Prinz Eugen'' after it survived the Operation Crossroads nuclear test in 1946. In the late 1950s, the US Army took over the base as part of their Nike Zeus anti-ballistic missile efforts, and since then the atoll has been widely used for missile tests of all sorts. Today it is part of the Ronald Reagan Ballistic Missile Defense Test Site, with various radars, tracking cameras, missile launchers, and many support systems spread across many islands. ...
