1.天基拦截弹(SBI) 天基拦截弹动能杀伤运载器是一种低轨道军用卫星,用来在敌人射弹处于助推段或后助推段时发射“灵巧”导弹,即天基拦截弹或天基拦截器。该运载器在目前研制阶段大约重800磅,长6英尺。它的重量设想还会减少200磅。单独的天基拦截弹仅重10磅,飞行速度为每秒10公里。每个卫星平台携带10枚这样的导弹。据国防部透露,初步计划这些系统携带导弹的总数约为250到350枚(数量最终取决于射弹的速度)。以估计部署1万到10万枚导弹为依据,利弗莫尔的马歇尔协会建立了其他模型。1984到1987财年中共拨出26400万美元用于
1. Space-based Interceptor Bullet (SBI) Space-based interceptor missile-capable vehicle is a low-orbit military satellite that is used to launch “smart” missiles when an enemy projectile is in a booster or after-booster section, Interceptor or space-based interceptor. The carrier weighs about 800 pounds and is 6 feet long at this stage of development. Its weight is reduced by 200 pounds. A single space-based interceptor just weighs 10 pounds, flying at 10 kilometers per second. Each satellite platform carries 10 such missiles. According to the Department of Defense, the total planned initial deployment of these systems is about 250 to 350 missiles (the number ultimately depends on the projectile’s speed). Based on an estimated deployment of 10,000 to 100,000 missiles, the Marshall Association of Livermore has established other models. From 1984 to 1987 fiscal year, the Chinese Communist Party allocated a total of 264 million U.S. dollars
