is incorporated into the recommended KV. The basic concept is to increase the cross-section of the KV around the seeker with a lightweight array to handle very closely spaced objects. The Exoatmospheric Reentry Interceptor Subsystem (ERIS) KV flown in 1991 had such an array. It employed a lightweight, inflatable tubular frame, which supported a thin membrane that was deployed several seconds before intercept on the basis of estimated time-to-go. While ERIS achieved direct body-to-body impact and also demonstrated the ability to select the aim point, the kill enhancement device provided a hedge against some countermeasures. The ERIS KKV, with its lethality enhancement device deployed, is shown in Figure 5-7.


Layered defense systems are desirable to increase engagement effectiveness, but individual layers should be implemented only if the value added is better and more cost effective than competing options. Layered defense is commonly
