The National Security Act. 1947. The National Security Act of 1947.
The National Security Act had three main parts. 1. It streamlined and unified the nation's military establishment by bringing together the Navy Department and War Department under a new Department of Defense. This department would facilitate control and utilization of the nation's growing military.
Second, The act established the National Security Council (NSC). Based in the White House, the NSC was supposed to serve as a coordinating agency, sifting through the increasing flow of diplomatic and intelligence information in order to provide the president with brief but detailed reports.
Finally, the act set up the Central Intelligence Agency (CIA). The CIA replaced the Central Intelligence Group, which had been established in 1946 to coordinate the intelligence-gathering activities of the various military branches and the Department of State. The CIA, however, was to be much more--it was a separate agency, designed not only to gather intelligence but also to carry out covert operations in foreign nations.
