里根政府的防卫技术研究小组在前国家航宇局管理人员James C Fletcher领导下,提出了一项到1989年费用为211亿美元的发展计划。这项计划旨在探索新的技术,其中包括大的新定向能量武器和预警卫星的轨道网,最终为美国及其盟国对苏联核武器进攻提供有效的弹道导弹防御系统。根据Fletcher的报告,用于防御弹道导弹的新技术有: 1)定向能量武器——核泵浦x射线激光器、中性粒子束、可见和红外高能激光器; The Reagan administration defense technology research group, led by former NASA administrator James C Fletcher, proposed a development plan that cost $ 21.1 billion by 1989. The project aims to explore new technologies, including a large network of new orienteering energy weapons and early warning satellites that eventually provide the United States and its allies with an effective ballistic missile defense system against the Soviet nuclear-weapon offensive. According to Fletcher’s report, new technologies used to defend ballistic missiles include 1) directional energy weapons - nuclear pumped x-ray lasers, neutral particle beams, visible and infrared high-energy lasers,
