MDA文档的截图,呵呵。重量数据应该算是近期看来比较准确的了,更新的文档我还没找到

好图。对于俄罗斯、中国这样在内陆腹地部署ICBM的国家,KEI根本无法实现助推段拦截。不过和GBI配合使用就可以实现多层拦截,拦截概率大大增加。
参见一篇有意思的文章:《美国在东欧部署反导系统针对谁?》

有一点疑问,上面文章说GBI现在似乎还没有和DSP整合,而是是靠地面远程预警雷达,是这样吗?

楼上同样好资料!

目前最现实的问题是,位于日本青森县的那台X波段雷达,对整个亚太地区的威胁太大了.仅从技术层面看,朝鲜全部,中国东部地区,俄远东地区所发射的导弹,仍然有助推段被拦截的可能.不光如此,台独在执政时,就连台湾都想过部署一部"铺路爪"系统.

KEI第一级燃烧时间约35秒,第二级24秒,第三级就是现在SM-3 BLK IA的第三级双脉冲发动机,两个脉冲分别燃烧10秒,耗尽速度大于6km/s。一、二级耗尽时,KEI应该就能达到助推段拦截高度(二级有很精确的姿控系统),第三级用于保持能量以达到中段拦截。

kktt兄,我的理解是:
GBI由于负责上升段以后的中段拦截,依靠整个传感器网络(包括DSP),它的接战时间很“充裕”。KEI由于时间紧迫,等预警卫星或前沿部署的预警雷达确认目标大概射向后立马发射。

Kinetic Energy Interceptor Prepares for Flight Testing with Simulated Launch Countdown

The Missile Defense Agency successfully completed an important exercise of the Kinetic Energy Interceptors (KEI) program in preparation for its inaugural flight test later this year. Team members executed simulated launch countdown activities of an inert pathfinder Kinetic Energy Interceptor (KEI) booster vehicle on April 9, 2009, at Vandenberg Air Force Base, Calif., as a risk reduction effort for the first flight test of the high- acceleration vehicle.   

The KEI pathfinder missile, fully functional with the exception of inert motors, was tested with range instrumentation, launch operations personnel and launch procedures. This pathfinder vehicle test has validated launch operations activities in preparation for flight testing.   

KEI is designed to be a mobile, globally deployable missile defense system featuring MDA’s newest high- acceleration booster. KEI will provide the Ballistic Missile Defense System (BMDS) with a capability to defeat long-range ballistic missiles during the boost, ascent, and midcourse phases of flight. By engaging hostile missiles in early stages of flight, KEI increases intercept opportunities and enhances the BMDS layered defensive capability.

The KEI program is managed by the Missile Defense Agency in Washington, D.C., and executed by the KEI Project Office in Huntsville, Ala.
