Aegis Ballistic Missile Defense System
The Aegis Ballistic Missile Defense System (Aegis BMD or ABMD), also known as ''Sea-Based Midcourse'', is a United States Department of Defense Missile Defense Agency program developed to provide missile defense against short to intermediate-range ballistic missiles. The program is part of the United States national missile defense strategy and European NATO missile defence system. Aegis BMD is an expansion of the Aegis Combat System deployed on warships, designed to intercept ballistic missiles in post-boost phase and prior to reentry. Aegis BMD-equipped vessels can engage potential threats using the Standard Missile 3 mid-course interceptors and the Standard Missile 2 and Standard Missile 6 terminal-phase interceptors.Aegis BMD web page , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aegis Bmd Mda
The aegis ( ; grc, αἰγίς ''aigís''), as stated in the ''Iliad'', is a device carried by Athena and Zeus, variously interpreted as an animal skin or a shield and sometimes featuring the head of a Gorgon. There may be a connection with a deity named Aex or Aix, a daughter of Helios and a nurse of Zeus or alternatively a mistress of Zeus (Hyginus, ''Astronomica'' 2. 13). The modern concept of doing something "under someone's ''aegis'' means doing something under the protection of a powerful, knowledgeable, or benevolent source. The word ''aegis'' is identified with protection by a strong force with its roots in Greek mythology and adopted by the Romans; there are parallels in Norse mythology and in Egyptian mythology as well, where the Greek word ''aegis'' is applied by extension. Etymology The Greek ''aigis'', has many meanings including: # "violent windstorm", from the verb ''aïssō'' (word stem ''aïg-'') = "I rush or move violently". Akin to ''kataigis'', "th ...

SM-3
The RIM-161 Standard Missile 3 (SM-3) is a ship-based surface-to-air missile system used by the United States Navy to intercept short- and intermediate-range ballistic missiles as a part of Aegis Ballistic Missile Defense System. Although primarily designed as an anti-ballistic missile, the SM-3 has also been employed in an anti-satellite capacity against a satellite at the lower end of low Earth orbit.Pentagon news briefing of February 14, 2008video : although no name for the satellite is given, the launch date of December 14, 2006 is stated The SM-3 is primarily used and tested by the and also operated by the |
George W
George Walker Bush (born July 6, 1946) is an American politician who served as the 43rd president of the United States from 2001 to 2009. A member of the Republican Party, Bush family, and son of the 41st president George H. W. Bush, he previously served as the 46th governor of Texas from 1995 to 2000. While in his twenties, Bush flew warplanes in the Texas Air National Guard. After graduating from Harvard Business School in 1975, he worked in the oil industry. In 1978, Bush unsuccessfully ran for the House of Representatives. He later co-owned the Texas Rangers of Major League Baseball before he was elected governor of Texas in 1994. As governor, Bush successfully sponsored legislation for tort reform, increased education funding, set higher standards for schools, and reformed the criminal justice system. He also helped make Texas the leading producer of wind powered electricity in the nation. In the 2000 presidential election, Bush defeated Democratic incum ...

Squib (explosive)
A squib is a miniature explosive device used in a wide range of industries, from special effects to military applications. It resembles a tiny stick of dynamite, both in appearance and construction, but has considerably less explosive power. They consist of two electrical leads separated by a plug of insulating material; a small bridge wire or electrical resistance heater; and a bead of heat-sensitive chemical composition, in which the bridge wire is embedded. They can be used to generate mechanical force to shatter or propel various materials; and for pyrotechnic effects for film and live theatrics. A squib generally consists of a small tube filled with an explosive substance, with a detonator running through the length of its core, similar to a stick of dynamite. Also similar to dynamite, the detonator can be a slow-burning fuse, or as is more common today, a wire connected to a remote electronic trigger. Squibs range in size from ~ in diameter.

RIM-2 Terrier
The Convair RIM-2 Terrier was a two-stage medium-range naval surface-to-air missile (SAM), and was among the earliest surface-to-air missiles to equip United States Navy ships. It underwent significant upgrades while in service, starting with beam-riding guidance with a range at a speed of Mach 1.8, and ending as a semi-active radar homing system with a range of at speeds as high as Mach 3. It was replaced in service by the RIM-67 Standard ER (SM-1ER). Terrier has also been used as a sounding rocket. History The Terrier was a development of the Bumblebee Project, the United States Navy's effort to develop a surface-to-air missile to provide a middle layer of defense against air attack (between carrier fighters and antiaircraft guns). It was test launched from on January 28, 1953, and first deployed operationally on the s, and in the mid-1950s, with ''Canberra'' being the first to achieve operational status June 15, 1956. Its US Navy designation was SAM-N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightweight Exo-Atmospheric Projectile
The Lightweight Exo-atmospheric Projectile (LEAP) is a lightweight miniaturized kinetic kill vehicle designed to destroy incoming ballistic missiles both inside or outside the Earth's atmosphere.Paul Baker, Buster Kelley, Anne Avetissian, ''Lightweight exo-atmospheric projectile (LEAP) Space Flight Test, June 1992, performance validation'', AIAA and SDIO, 2nd Annual Interceptor Technology Conference, Albuquerque, NM, June 6–9, 1993 The warhead is delivered to the interception point by a system such as the Aegis Ballistic Missile Defense System. History Development began in 1985 by the Strategic Defense Initiative Organization, which pioneered the development of miniaturized kill vehicle technology. It was originally created by the now-defunct Hughes Aircraft Company; the modern versions are developed and built by Raytheon.

Railgun
A railgun or rail gun is a linear motor device, typically designed as a weapon, that uses Electromagnet, electromagnetic force to launch high velocity projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high speed, mass, and kinetic energy to inflict damage. The railgun uses a pair of parallel conductors (rails), along which a sliding Armature (electrical engineering), armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail. It is based on principles similar to those of the homopolar motor. As of 2020, railguns have been researched as weapons utilizing electromagnetic forces to impart a very high kinetic energy to a projectile (e.g. APFSDS) rather than using conventional propellants. While explosive-powered military guns cannot readily achieve a muzzle velocity of more than ≈, railguns can readily exceed . For a similar projectile, the ra ...

Strategic Defense Initiative
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 be ...
