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 Ground Based Interceptor (GBI) was launched and successfully deployed an Exoatmospheric Kill Vehicle (EKV). January 2010 : MDA conducted a flight test of the Ground-based Midcourse Defense System which failed to intercept its target.

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 GBI consists of a multi-stage rocket booster (Boost Vehicle [BV]) and a kinetic kill vehicle (Exoatmospheric Kill Vehicle [EKV]), which makes interception of ballistic missile warheads possible using hit-to-kill technology.

2019年8月21日 · The RKV would have replaced the current Exoatmospheric Kill Vehicle (EKV) on the Ground-Based Interceptor, which makes up the Ground-based Midcourse Defense (GMD) system designed to protect the...

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.

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。

2023年12月17日 · 美国在7,380亿美元的2020财政年度《国防授权法》（NDAA）中，导弹防御局（MDA）的获得的资金达到了104亿美元，其中一项关键的计划是启动和研发 下一代拦截器（NGI），同时提高第一代地面拦截器（GBI）的可靠性，提高现有的“宙斯盾”分层导弹防御系统的能力。 此外，这些防御性法案首次提出并资助超音速和弹道跟踪空间传感器（HBTSS）和超音速防御拦截计划。 MDA负责这些重要任务的开发，测试和部署。 其中所提出的NGI将取代目前 …
