指挥、控制、通信与情报系统(简称C~3I)是一种以计算机为核心技术设备的军用信息系统。它始自50年代美军“赛其”半自动防空系统的问世。60年代美军又组建了称为“全球军事指挥控制系统”(WWMCCS)的战略C~3I系统,主要用来指挥控制其战略核部队。WWM-CCS是一项庞大复杂的系统工程,由国家级指挥中心、探测预警系统和通信系统三大部分组成。它呈多级伞状结构,共和各种重要的分系统数十个。80年代美国里根政府极为重视C~3I建设,不但对WWMCCS作了多方面改进,还把C~3I置于与核武器同等重要的地位,作为国家威慑力量的组成部分。目前美军广泛使用的GPS全球定位系统和Milstar卫星通信系统都是那时开始研制的。在此期间,前苏联和北约的C~3I系统也有了
Command, Control, Communication and Intelligence System (C ~ 3I) is a military information system with computer as the core technology and equipment. It started with the advent of the semi-automatic air defense system of the U.S. Army in the 1950s. In the 1960s, the U.S. military also established a strategic C-3I system called the “Global Military Command and Control System” (WWMCCS), which is mainly used for directing and controlling its strategic nuclear forces. WWM-CCS is a large and complex system engineering. It consists of three major components: state command center, early warning system and communication system. It is a multi-level umbrella structure, a total of dozens of various important subsystems. In the 1980s, the Reagan administration attached great importance to the construction of C ~ 3I. It not only made many improvements to WWMCCS but also placed C ~ 3I on the same status as nuclear weapons as an integral part of the deterrent force of the state. At present, both the GPS and the Milstar satellite communications system widely used by the U.S. military were developed at that time. During this period, there were also C ~ 3I systems in the former Soviet Union and NATO
