Anti-missile projects and their origins
The first anti-missile projects of defense date back to the Second World War. The present document describes the evolution of the American doctrines since end of the year 1990. The project Star Wars was launched by Ronald Reagan in 1981; the United States carried out substantial investments on this program, by distancing the possible competitors, and had begun the implementation of these projects.
Without guarantee, the leaders seldom express vocally that, this project, is to be used only in the event of major crisis. It modifies the balances of the forces with other nations and calls in question the traditional principle of dissuasion.
The general principle of such a defense is the destruction of a ballistic missile during one of the three phases of its trajectory: during launching powered (interception early -boost phase intercept), the trajectory or the Outer phase descent, often performed in free fall. Destruction can be made by the explosion of a nuclear warhead in the vicinity, which, if not destruction, should at least allow blurring the guiding magnet system (with the risk of falling then random missile). The current anti-ballistic missiles with a longer working principle of kinetic interception, which simply means destruction by collision (hit to kill).
Because of the speeds reached by missiles (especially descent phase), the relative velocity of the missile (the missile is approx 10km/s) and decoy systems should be accompanied by a highly developed detection device that is as fast as possible.
