Homing Overlay Experiment
The Strategic Defense Initiative (SDI), derisively nicknamed the "''Star Wars'' program", was a proposed missile defense system intended to protect the United States from attack by ballistic strategic nuclear weapons (intercontinental ballistic missiles and submarine-launched ballistic missiles). The concept was announced on March 23, 1983, by President Ronald Reagan,Federation of American ScientistsMissile Defense Milestones Accessed March 10, 2007. a vocal critic of the doctrine of mutually assured destruction (MAD), which he described as a "suicide pact". Reagan called upon American scientists and engineers to develop a system that would render nuclear weapons obsolete. The Strategic Defense Initiative Organization (SDIO) was set up in 1984 within the US Department of Defense to oversee development. A wide array of advanced weapon concepts, including lasers, Duarte, F. J. (Ed.), ''Proceedings of the International Conference on Lasers '87'' (STS, McLean, Va, 1988). particle bea ...

Ballistic Missile Defense Organization
The Ballistic Missile Defense Organization (BMDO) was an agency of the United States Department of Defense that began on 20 May 1974 with the responsibility for all U.S. ballistic missile defense efforts. It was renamed the Missile Defense Agency in 2002. History It evolved from the SAFEGUARD System Organization. The original mission of BMDO was comparable to that of SAFEGUARD, which was to defend U.S. ballistic missile sites, but BMDO additionally had the more general role of conducting research and development in advanced ballistic missile defense (BMD) technology and also managed what was then called the Kwajalein Missile Range (KMR). In July 1984, BMDO became a part of the Strategic Defense Initiative Organization (SDIO) and one year later BMDO was renamed the U.S. Army Strategic Defense Command. The name "Ballistic Missile Defense Organization" (BMDO) came back into use in 1993 when SDIO was renamed BMDO by the administration of President Bill Clinton and this was ac ...

Basic Research
Basic research, also called pure research or fundamental research, is a type of scientific research with the aim of improving scientific theories for better understanding and prediction of natural or other phenomena. In contrast, applied research uses scientific theories to develop technology or techniques which can be used to intervene and ''alter'' natural or other phenomena.

National Defense Authorization Act
The National Defense Authorization Act (NDAA) is the name for each of a series of United States federal laws specifying the annual budget and expenditures of the U.S. Department of Defense. The first NDAA was passed in 1961. The U.S. Congress oversees the defense budget primarily through two yearly bills: the National Defense Authorization Act and defense appropriations bills. The authorization bill is the jurisdiction of the Senate Armed Services Committee and House Armed Services Committee and determines the agencies responsible for defense, establishes recommended funding levels, and sets the policies under which money will be spent. The appropriations bill provides funds. The passage of a Defense Authorization Act is often used by Congress to honour a senior congress member or other individual. For example, the National Defense Authorization Act for Fiscal Year 2001 is known as the "Floyd D. Spence National Defense Authorization Act for Fiscal Year 2001" in honour of Repre ...

Theatre Ballistic Missile
A theatre ballistic missile (TBM) is any ballistic missile with a range less than , used against targets " in-theatre". Its range is thus between that of tactical and intermediate-range ballistic missiles. The term is a relatively new one, encompassing the former categories of short-range ballistic missile and medium-range ballistic missile. Examples of this type of in-theatre missile are the Soviet RT-15, TR-1 Temp and American PGM-19 Jupiter missile, both from the 1960s. Specific TBMs Specific types of TBMs (current, past and under development) include: * B-611 * BP-12/A * DF-11 * DF-12/M20 * DF-15 * Type 621 * Type 631 * DF-2 * DF-16 * DF-17 * DF-21 (China) , (Saudi Arabia) * Hadès * Pluton * SE.4200 * SSBS S1 * Agni I * K-15 * Prahaar * Pragati (planned) * Pralay * Pranash (planned) * Prithvi I * Prithvi II * Prithvi III * Shaurya * Agni II * Agni-P * Fateh-110 * Fateh-313 * Fateh Mobin * Naze'at * Qiam 1 * Ra'ad-5 ...

Clinton Administration
Bill Clinton's tenure as the 42nd president of the United States began with his first inauguration on January 20, 1993, and ended on January 20, 2001. Clinton, a Democrat from Arkansas, took office following a decisive election victory over Republican incumbent president George H. W. Bush and independent businessman Ross Perot in 1992. Four years later, in 1996, he defeated Perot again (then as the nominee of the Reform Party) and Republican nominee Bob Dole, to win re-election; in neither ballot did he obtain a majority of the popular vote. Clinton was succeeded by Republican George W. Bush, who won the 2000 presidential election. The nation experienced an extended period of economic prosperity during the Clinton presidency. While the economy remained strong, his presidency oscillated dramatically from high to low and back again, which historian Gil Troy characterized in six Acts. Act I in early 1993 was "Bush League" with amateurish distractions. By mid-1993 Clinton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arms Race
An arms race occurs when two or more groups compete in military superiority. It consists of a competition between two or more states to have superior armed forces; a competition concerning production of weapons, the growth of a military, and the aim of superior military technology, the term is also used to describe any long-term escalating competitive situation where each competitor or competitive group focuses on out-doing others. Unlike a sporting race, which constitutes a specific event with winning interpretable as the outcome of a singular project, arms races constitute spiralling systems of on-going and potentially open-ended behavior. The existing scholarly literature is divided as to whether arms races correlate with war. International-relations scholars explain arms races in terms of the security dilemma, rationalist spiral models, states with revisionist aims, and deterrence models. Examples Pre-First World War naval arms race From 1897 to 1914, a nav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-to-air Missile
The newest and the oldest member of Rafael's Python family of AAM for comparisons, Python-5 (displayed lower-front) and Shafrir-1 (upper-back) An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors, usually solid fueled but sometimes liquid fueled. Ramjet engines, as used on the Meteor, are emerging as propulsion that will enable future medium-range missiles to maintain higher average speed across their engagement envelope. Air-to-air missiles are broadly put in two groups. Those designed to engage opposing aircraft at ranges of less than 16 km are known as short-range or "within visual range" missiles (SRAAMs or WVRAAMs) and are sometimes called "dogfight" missiles because they are designed to optimize their agility rather than range. Most use infrared guidance and are called heat-seeking missiles. In contrast, medium- or long-range missiles (MRAAMs or L ...

Brilliant Pebbles
Brilliant Pebbles was a Missile defense, ballistic missile defense (BMD) system proposed by Lowell Wood and Edward Teller of the Lawrence Livermore National Laboratory (LLNL) in 1987, near the end of the Cold War. The system would consist of thousands of small missiles, similar to conventional heat seeking missiles, which would be placed in low Earth orbit megaconstellation, constellations so that hundreds would be above the Soviet Union at all times. If the Soviets launched its Intercontinental ballistic missile, ICBM fleet, the pebbles would detect their rocket motors using Infrared homing, infrared seekers and collide with them. Because the pebble strikes the ICBM before the latter could release its warheads, each pebble could destroy several warheads with one shot. The name is a play on the idea of Smart Rocks, a concept promoted by Daniel O. Graham as part of the Strategic Defense Initiative (SDI). This used large battle stations with powerful sensors, carrying dozens of sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
