新华社北京8月13日电 根据美国政府最新幻灯片演示，研发中的"金穹"天基导弹防御系统包含四层 防御系统，一层基于卫星，三层部署在陆地，其中11个短程导弹发射装置将分布在美国本土、阿拉斯加 和夏威夷。 路透社报道说，幻灯片展示了该导弹防御系统"前所未有的复杂性"和研发过程中的技术难题。 四层防御系统 路透社13日报道，美国政府上周在亚拉巴马州亨茨维尔以幻灯片形式向防务承包商展示"金穹"系统 细节。材料显示，"金穹"系统架构由四个集成层组成：一个天基传感和目标瞄准层，用于导弹预警、跟 踪及"导弹防御"；三个陆基层，包含导弹拦截器、雷达阵列，还可能配备激光武器。 幻灯片显示，由于该系统所需的发射器、拦截器、地面站和导弹发射场的数量尚未确定，项目的基 本架构存在不确定性。 路透社报道说，令人"意外"的是，幻灯片展示的地图上显示，美军看起来计划在中西部新建一个大 型导弹发射场，用于部署"下一代拦截弹"，并将与"萨德""宙斯盾"反导系统一起构成所谓"上层防御"。 美国国防部下属的导弹防御局2024年4月宣布委托美国军火商洛克希德-马丁公司研发"下一代拦截 弹"，并表示这是提升陆基中段防御系统的重要部分，将力争不晚于202 ...
