Exoatmospheric Kill Vehicle prototype. The Exoatmospheric Kill Vehicle (EKV) is the Raytheon-manufactured interceptor component with subcontractor Aerojet of the U.S. Ground-Based Midcourse Defense (GMD), part of the larger National Missile Defense system.
In the case of bodies with substantial atmospheres, such as Earth's atmosphere, the exosphere is the uppermost layer, where the atmosphere thins out and merges with outer space. It is located directly above the thermosphere. Very little is known about it due to a lack of research.
It is designed for exo-atmosphere interception of ballistic missiles during the spaceflight portion of their trajectory, including those of ICBMs. [2] It may also act as an anti-satellite weapon. The American Ground-Based Midcourse Defense (GMD) system, formerly known as National Missile Defense (NMD), was first tested in 1997 and had its first ...
The Japanese Defense Ministry is considering allocating money in the fiscal 2015 state budget for research on introducing the ground-based SM-3. Japanese ballistic missile defense strategy involves ship-based SM-3s to intercept missiles in space, while land-based Patriot PAC-3 missiles shoot down missiles SM-3s fail to intercept. Due to concern ...
Conducted a successful exo-atmospheric test at the Pacific Missile Range Facility (PMRF) off Kauai, Hawaii. The flight test demonstrated the system's ability to detect, track and intercept an incoming unitary target above the Earth's atmosphere. The missile was hot-condition tested to prove its ability to operate in extreme environments. [23] [24]
Lightweight Exo-atmospheric Projectile. The Lightweight Exo-atmospheric Projectile (LEAP) is a lightweight miniaturized kinetic kill vehicle designed to destroy incoming ballistic missiles both inside [1] or outside the Earth's atmosphere. [2] The warhead is delivered to the interception point by a system such as the Aegis Ballistic Missile ...
The environment of the explosion (e.g. submarine, ground burst, air burst, or exo-atmospheric) determines how much energy is distributed to the blast and how much to radiation. In general, surrounding a bomb with denser media, such as water, absorbs more energy and creates more powerful shock waves while at the same time limiting the area of ...
High Endoatmospheric Defense Interceptor (HEDI) was an atmospheric missile defense layer developed for the Strategic Defense Initiative, along with Exoatmospheric Reentry-vehicle Interceptor Subsystem. It consisted of a two-stage launch vehicle (booster) and an infrared homing kill vehicle with a conventional warhead. [1]
