Worldwide Military Command and Control System
The Worldwide Military Command and Control System, or WWMCCS /ˈwɪmɛks/, was a military command and control system implemented for the command and control of the United States military. It was created in the days following the Cuban Missile Crisis. WWMCCS was a complex of systems that encompassed the elements of warning, communications, data collection and processing, executive decision-making tools and supporting facilities. It was decommissioned in 1996 and replaced by the Global Command and Control System.

Background[edit]
The worldwide deployment of U.S. forces required extensive long-range communications systems that can maintain contact with all of those forces at all times. To enable national command authorities to exercise effective command and control of their widely dispersed forces, a communications system was established to enable those authorities to disseminate their decisions to all subordinate units, under any conditions, within minutes.
Such a command and control system, WWMCCS, was created by Department of Defense Directive S-5100.30, titled "Concept of Operations of the Worldwide Military Command and Control System," which set the overall policies for the integration of the various command and control elements that were rapidly coming into being in the early 1960s.
As initially established, WWMCCS was an arrangement of personnel, equipment (including Automated Data Processing equipment and hardware), communications, facilities, and procedures employed in planning, directing, coordinating, and controlling the operational activities of U.S. military forces.
This system was intended to provide the President and the Secretary of Defense with a means to receive warning and intelligence information, assign military missions, provide direction to the unified and specified commands, and support the Joint Chiefs of Staff in carrying out their responsibilities. The directive establishing the system stressed five essential system characteristics: survivability, flexibility, compatibility, standardization, and economy.
Problems[edit]
Despite the original intent, WWMCCS never realized the full potential that had been envisioned for the system. The services' approach to WWMCCS depended upon the availability of both technology and funding to meet individual requirements, so no truly integrated system emerged. Indeed, during the 1960s, WWMCCS consisted of a loosely knit federation of nearly 160 different computer systems, using 30 different general purpose software systems at 81 locations.[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] One study claimed that WWMCCS was "more a federation of self-contained subsystems than an integrated set of capabilities."
The problems created by these diverse subsystems were apparently responsible for several well-publicized failures of command and control during the latter part of the 1960s.
During hostilities between Israel and Egypt in June 1967, the USS Liberty, a naval reconnaissance ship, was ordered by the JCS to move further away from the coastlines of the belligerents. Five high-priority messages to that effect were sent to the Liberty, but none arrived for more than 13 hours. By that time the ship had become the victim of an attack by Israeli aircraft and patrol boats that killed 34 Americans.[28]
A congressional committee investigating this incident concluded, "The circumstances surrounding the misrouting, loss and delays of those messages constitute one of the most incredible failures of communications in the history of the Department of Defense."
Furthermore, the demands for communications security (COMSEC) frustrated upgrades and remote site computer and wiring installation. TEMPEST requirements of the Cold War day required both defense from wire tapping and electromagnetic signal intercept, special wire and cabinet shielding, physical security, double locks, and special access passes and passwords.
