History
This position was created in 1947 when the Navy, Army, and newly created Air Force were merged into the new National Military Establishment. In the same massive reorganization, the Secretary of War was replaced by the Secretary of the Army and, along with the Secretary of the Navy and the new Secretary of the Air Force, became a non-Cabinet position placed under the Secretary of Defense. In 1949, the National Military Establishment was renamed the Department of Defense, which remains the current name of the department.
The SecDef and the President of the United States together constitute the National Command Authority (NCA), which has sole authority to launch strategic nuclear weapons. All nuclear weapons are governed by the two-man rule, even at the highest levels in government. Both individuals must concur before a strategic nuclear strike may be ordered.
The SecDef, as the head of the United States Office of the Secretary of Defense, is assisted by a Deputy Secretary and five Under Secretaries in the fields of Acquisition, Technology & Logistics; Comptroller/Chief Financial Officer; Intelligence; Personnel & Readiness; and arguably the most important, Policy. All of these positions require Senate confirmation.
