A Ground-Based Interceptor loaded into a silo at Fort Greely, Alaska in July 2004.. Ground-Based Midcourse Defense (GMD), previously National Missile Defense (NMD), is an anti-ballistic missile system implemented by the United States of America for defense against ballistic missiles, during the midcourse phase of ballistic trajectory flight.
A ballistic missile ... The mid-course phase is the longest in the missile's trajectory, beginning with the conclusion of powered flight. ... online book review ...
The midcourse phase represents the majority of the time of flight of a ballistic missile, from minutes to the better part of an hour depending on the range of the missile. During this phase the payload follows a ballistic trajectory, with warheads, decoys and radar reflectors mixed together in an extended formation known as the target cloud. In ...
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.
The motto in Latin: Custos Custodum Ipsorum means "Guard of the Guardians Themselves" in English. The Aegis ballistic missile defense system (Aegis BMD or ABMD), [1] also known as Sea-Based Midcourse, is a Missile Defense Agency program under the United States Department of Defense developed to provide missile defense against short and intermediate-range ballistic missiles.
Intercept: Most systems can be used in different phases of ballistic missile flight, i.e., boost [73] (where surface or air-launched anti-aircraft missiles might also be effective because the ballistic missile is moving relatively slowly at low altitude), requiring proximity to the launch site and immediate response, mid-course/exo-atmospheric ...
Common examples include long-range air-to-air missiles that use semi-active radar homing (SARH) during most of the missile's flight, and then use an infrared seeker or active radar homing once they approach their target. Similar examples include surface-to-air missiles, anti-ballistic missiles, and some anti-tank missiles.
The Missile Defense Agency leads the development of anti-ballistic missiles for North America. The Next Generation Interceptor (NGI) [21]: 4:13 is a MDA program to upgrade the kill vehicles for the ground-based interceptors, with different vendors, Lockheed Martin and Northrop Grumman competing.
