Answer:
The new government agencies that were created by the National Security Act were the Central Intelligence Agency, the National Security Council and the Department of Defense.
Step-by-step explanation:
The National Security Act of 1947 was an act that realigned and reorganized the US armed forces, foreign policy, and the intelligence apparatus after the end of World War II.
The act combined the War Department and the Department of the Navy in the National Military Establishment (NME) led by the Secretary of Defense, which was renamed the United States Department of Defense in 1949.
In addition to the military reorganization, the National Security Act established the National Security Council, a coordination center for national security policies in the executive branch, and the Central Intelligence Agency (CIA); the first American intelligence agency established in times of peace.
