Exoatmospheric Kill Vehicle
|This article needs additional citations for verification. (February 2008)|
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.
The EKV is boosted to an intercept trajectory by a boost vehicle (missile), where it separates from the boost vehicle and autonomously collides with an incoming warhead.
The EKV is launched by the Ground-Based Interceptor (GBI) missile, the launch vehicle of the Ground-Based Midcourse Defense System. The EKV's own rockets and fuel are for corrections in the trajectory, not for further acceleration.
