D. Security System Concepts 1. Security for nuclear weapons is provided by in-depth systems that provide deterrence, detection, delay, and denial of individuals who are not authorized access to a nuclear weapon. These same systems may provide protection from damage attempts including stand-off attacks. Security systems are designed in response to actual validated threats or postulated threats that may arise as adversary intentions develop. Detection must be accomplished through physical or electronic measures that detect possible threats to nuclear weapons at the earliest possible point when an attempt or the preparation for an attempt to penetrate the system is being made.
Denial is the ultimate goal of delay and is the nullifying, repulsing, or termination of an attack.
Diverse and redundant communications to ensure command and control. The efficient installation and operation of the security system, including the training and exercising of response forces, shall be sufficiently imposing to deter potential attacks. Deterrence is the first line of defense, but is only effective when supported by an active, operational security system. Consequently, security forces shall be trained as they would be expected to be employed.
