The Exo-atmospheric Kill Vehicle (EKV) is a sensor/propulsion package that uses the kinetic energy from a direct hit to destroy the incoming target vehicle. This hit-to-kill technology has been proven in a number of successful flight tests, including three using Ground-Based Interceptors.

Ground-Based Midcourse Defense (GMD), previously National Missile Defense (NMD), is an anti-ballistic missile system implemented by the United States of America for defense against ballistic missiles, during the midcourse phase of ballistic trajectory flight.

The Exo-atmospheric Kill Vehicle (EKV) is a sensor/ propulsion package that uses the kinetic energy from a direct hit to destroy the incoming target vehicle. [1] In the late 1990s, North Korea demonstrated significant progress on its nuclear and ballistic missile program, particularly in its ability to strike the U.S. homeland.

2023年12月13日 · In the wake of its latest test of the Ground-based Midcourse Defense (GMD) system, the U.S. Missile Defense Agency has published a video explainer that provides a very useful description of what exactly happened in that complex engagement process, as well as how much of the overarching U.S. missile defense architecture actually works.

2021年7月26日 · The Exo-atmospheric Kill Vehicle (EKV) is the GMD’s means of physically destroying incoming target missiles. The EKV consists of a sensor-propulsion package that collides with the re-entry vehicle during the midcourse phase of the missile’s ballistic trajectory, using its own infrared seeker, guidance system, and motor.

2020年1月30日 · In August 2019, hardware-in-the-loop ground testing requested by USNORTHCOM assessed sensor performance, GMD fire control engagement planning and execution, and Exo-atmospheric Kill Vehicle (EKV) performance. The MDA conducted the first operational flight test of the GMD weapon system in March 2019.

2022年8月1日，mda授予诺斯罗普·格鲁曼公司一份升级gmd系统的合同，以实现拦截弹硬件的现代化。 大气层外杀伤器(EKV)是雷声公司与Aerojet制造的拦截器组件， EKV由拦截弹发射至拦截轨道后分离，使用自身的燃料来修正轨道，不再进一步加速。

2023年12月13日 · 作为美国国家导弹防御系统（NMD）的一部分，EKV由中段拦截系统的陆基拦截弹（GBI）发射，并使用自身燃料进行轨道修正，采用直接碰撞方式摧毁目标。 中段拦截系统所部署的GBI是一种三级固体轨道助推火箭，其两级版本则用于欧洲方向的北约导弹防御系统，此次试验则是中段拦截系统的三级拦截弹首次以“二级模式”进行拦截测试——即指令第三级不要点火，并提前分离杀伤拦截器，以提供在更近距离上的拦截，这一测试成功利用了已部署拦截弹的 …

2019年11月12日 · The current Exoatmospheric Kill Vehicles (EKV) were deployed in the early 2000s and rely upon 1990s-era technology. Essentially advanced prototype s, the EKVs rely on complex and unique designs that create production and …

2023年12月17日 · 在美国反导拦截体系中，最为关键的拦截武器是GBI.GBI携带的动能拦截弹头称为EKV，是美国第一代已经装备的大气层外动能拦截弹头，目前已经部署了44枚拦击弹。
