The Central Security Service (CSS) is a combat support agency of the United States Department of Defense which was established in 1972 to integrate the National Security Agency (NSA) and the Service Cryptologic Components (SCC) of the United States Armed Forces in the field of signals intelligence, cryptology, and information assurance at the tactical level.

The Goldwater–Nichols Department of Defense Reorganization Act of October 4, 1986 made the most sweeping changes to the United States Department of Defense since the department was established in the National Security Act of 1947 by reworking the command structure of the U.S. military. It increased the powers of the chairman of the Joint Chiefs of Staff and implemented some of the suggestions from the Packard Commission, commissioned by President Reagan in 1985. Among other changes, Goldwater–Nichols streamlined the military chain of command, which now runs from the president through the secretary of defense directly to combatant commanders, bypassing the service chiefs. The service chiefs were assigned to an advisory role to the president and the secretary of defense, and given the responsibility for training and equipping personnel for the unified combatant commands.

Gaining its independence from the Army on 18 September 1947, the United States Air Force began development of military space and ballistic missile programs, while also competing with the United States Army and United States Navy for the space mission.
