 美国的“使用控制”设计特征通过电子和机械特性排除或推迟未经授权的核爆炸。实例包括核武器启动连接装置、使弹头无法爆炸的命令失能，以及在发现篡改时使关键的弹头部件失能的积极保护系统。
 U.S. “use control” design features preclude or delay unauthorized nuclear detonation through electronic and mechanical features. Examples include permissive action links, command disablement to render warheads inoperable, and active protection systems that disable critical warhead components when tampering is detected.
