(Bonus) The Strategic Defense Initiative - Wikipedia

(Bonus) 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 (intercontinental ballistic missiles and submarine-launched ballistic missiles). The concept was announced on March 23, 1983, by President Ronald Reagan,[1] 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.[2] Elements of the program reemerged in 2019 with the Space Development Agency (SDA).[3]

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,[4][5] particle beam weapons, and ground and space-based missile systems were studied, along with various sensor, command and control, and high-performance computer systems that would be needed to control a system consisting of hundreds of combat centers and satellites spanning the entire globe and involved in a very short battle. The United States held a significant advantage in the field of comprehensive advanced missile defense systems through decades of extensive research and testing; a number of these concepts and obtained technologies and insights were transferred to subsequent programs
