Strategic Defense Initiative

The Strategic Defense Initiative (SDI), nicknamed the Star Wars program, was a proposed missile defense system intended to protect the United States from attack by ballistic strategic nuclear weapons. The concept was announced on March 23, 1983, by President Ronald Reagan, 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. Elements of the program reemerged in 2019 with the Space Development Agency (SDA).

The bright spikes extending below the initial fireball of one of 1952's Operation Tumbler–Snapper test shots, are known as the "rope trick effect". They are caused by the intense flash of thermal/soft X-rays released by the explosion heating the steel tower guy-wires white hot. The development of the W71 and the Project Excalibur x-ray laser were based on enhancing the destructive effects of these x-rays.

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.
