United States Secretary of Defense
The
United States Secretary of Defense is the head of the
United States Department of Defense concerned with the
armed services and
military matters. The Secretary is a member of the
President's Cabinet.
This position was created in 1947, when the Navy, Army, and newly created Air Force were merged into the new Department of Defense. In the same massive reorganization, the Secretary of the Navy was changed to a non-Cabinet position placed under the Secretary of Defense and the Secretary of War was replaced by the Secretary of the Army, also a non-Cabinet position under the Secretary of Defense.
