National Communications System

The National Communications System (NCS) was an office within the United States Department of Homeland Security charged with enabling national security and emergency preparedness communications (NS/EP telecommunications) using the national telecommunications system. The NCS was disbanded by Executive Order 13618 on July 6, 2012.

The genesis of the NCS began in 1962 after the Cuban Missile Crisis when communications problems among the United States, the Union of Soviet Socialist Republics, the North Atlantic Treaty Organization, and foreign heads of state threatened to complicate the crisis further. After the crisis, President John F. Kennedy ordered an investigation of national security communications, and the National Security Council (NSC) formed an interdepartmental committee to examine the communications networks and institute changes. This interdepartmental committee recommended the formation of a single unified communications system to serve the President, Department of Defense, diplomatic and intelligence activities, and civilian leaders. Consequently, in order to provide better communications support to critical government functions during emergencies, President Kennedy established the National Communications System by a Presidential Memorandum on August 21, 1963. The NCS mandate included linking, improving, and extending the communications facilities and components of various Federal agencies, focusing on interconnectivity and survivability.

On April 3, 1984, President Ronald Reagan signed Executive Order (E.O.) 12472 which broadened the NCS' national security and emergency preparedness (NS/EP) capabilities and superseded President Kennedy's original 1963 memorandum. The NCS expanded from its original six members to an interagency group of 23 federal departments and agencies, and began coordinating and planning NS/EP telecommunications to support crises and disasters.
