The Kill Vehicle utilizes three Focal Plane detector arrays, two IR and the third a visible CCD array designed and manufactured by Goodrich. The visible FPA assembly is used to determine spatial location and orientation and ultimately hand the acquisition and tracking of the target(s) off to the IR detectors. The Kill Vehicle engages the high speed warheads in the exo-atmospheric phase of their trajectories and destroys them using only the force of impact.

The Visible Focal Plane Array, shown above in its shipping fixture, is comprised of a 256x256 pixel frame transfer array, and a flexible ribbon cable which interfaces the CCD to the Goodrich-designed Visible Sensor Electronics. The EKV vehicle has performed four successful intercepts of ballistic missile targets to date, the latest, designated IFT-8 on 15 March 2002.
