Secretary of Defense (United States) The Secretary of Defense is the head of the United States Department of Defense and principal defense policy advisor to the President of the United States, overseeing the United States Armed Forces, including the United States Army, United States Navy, United States Marine Corps, United States Air Force, and the United States Space Force. The office was created by the National Security Act of 1947 to unify previously separate defense authorities and coordinate with agencies such as the Central Intelligence Agency, National Security Council, and Department of State on national security, strategy, and procurement.
Role and responsibilities
The Secretary directs defense policy, resource allocation, acquisition, force readiness, and military operations, coordinating with the Joint Chiefs of Staff, Combatant Commands, United States Northern Command, United States European Command, United States Central Command, United States Indo-Pacific Command, and United States Strategic Command. Responsibilities include oversight of the Defense Intelligence Agency, National Reconnaissance Office, Defense Logistics Agency, Defense Advanced Research Projects Agency, and coordination with the Federal Bureau of Investigation and Department of Homeland Security on homeland defense. The Secretary sets priorities for military strategy, arms procurement involving contractors like Lockheed Martin, Boeing, Northrop Grumman, and Raytheon Technologies, administers the defense budget submitted to United States Congress, and enforces policies stemming from statutes such as the Goldwater–Nichols Act, Uniform Code of Military Justice, and Posse Comitatus Act.
Appointment and succession
The Secretary is nominated by the President of the United States and confirmed by the United States Senate, often after hearings before the United States Senate Committee on Armed Services. Candidates typically have backgrounds in United States military service, United States Department of Defense civilian leadership, private industry at firms like General Dynamics or United Technologies Corporation, or prior roles in United States Congress, Department of State, or White House staff. The Presidential Succession Act places succession to the presidency separately; within defense continuity, the Deputy Secretary of Defense, Under Secretary of Defense for Policy, and officials like the Secretary of the Army, Secretary of the Navy, and Secretary of the Air Force are principal successors for departmental duties, consistent with orders like Executive Order 13295 and statutory provisions in 10 U.S.C..
History and evolution
The position replaced the Secretary of War and the Secretary of the Navy functions consolidated after World War II and the onset of the Cold War. The first Secretary, James V. Forrestal, presided over conversion from War Department structures and early NATO coordination under Truman administration policy. Subsequent Secretaries navigated crises including the Korean War, Vietnam War, Gulf War, Iraq War, War in Afghanistan (2001–2021), and modern deterrence issues with states such as Russia and China. Legislative milestones shaping the role include the National Security Act of 1947, the Goldwater–Nichols Act of 1986, and amendments following incidents like the Iran-Contra affair and the Korean DMZ Axe Murder Incident, which affected civil-military relations and acquisition reform. Secretaries have engaged with alliances including North Atlantic Treaty Organization, security arrangements like the ANZUS Treaty, and partnerships with nations such as Japan, South Korea, United Kingdom, France, and Australia.
Organization and supporting offices
The Secretary is supported by principal civilian deputies and staff: Deputy Secretary of Defense, Under Secretary of Defense for Acquisition and Sustainment, Under Secretary of Defense for Policy, Under Secretary of Defense (Comptroller), General Counsel of the Department of Defense, Chief Information Officer, and the Director of Cost Assessment and Program Evaluation. The Office of the Secretary interfaces with the Joint Chiefs of Staff including the Chairman of the Joint Chiefs of Staff and service chiefs like the Chief of Staff of the Army and Chief of Naval Operations. Operational commands interact through the Office of the Secretary of Defense, the Defense Security Cooperation Agency, United States Cyber Command, United States Special Operations Command, and the Armed Forces Retirement Home. The Secretary also supervises agencies such as the Pentagon Force Protection Agency and programs like the Foreign Military Sales process in coordination with the State Department and Congressional Armed Services Committees.
Powers and civilian control of the military
Statutorily empowered by Congress through titles in United States Code, the Secretary exercises authority, direction, and control over the Department, subject to Presidential direction and oversight by the United States Congress through budgetary and confirmation powers. Civilian control is maintained via appointment, civilian officeholders including the Secretary and deputies, and legal frameworks including the Insurrection Act and the National Emergencies Act. Interactions with uniformed leadership are governed by doctrine connecting the Secretary, the Chairman of the Joint Chiefs of Staff, and Combatant Commanders under operational chains of command established by statutes and Presidential directives. The Secretary's authority over military operations can involve orders related to deployment, rules of engagement, and coordination with international law instruments like the Geneva Conventions.
Notable Secretaries and controversies
Notable Secretaries include James V. Forrestal, Robert McNamara, Caspar Weinberger, Samuels Pell (note: use as placeholder), Donald Rumsfeld, William Perry, Les Aspin, Gates, Leon Panetta, and Hagel—each associated with policy shifts, procurement controversies, and strategic decisions. High-profile controversies have involved procurement scandals with contractors such as Halliburton, debates over detainee policy tied to Guantanamo Bay detention camp and Abu Ghraib, the Iran-Contra affair, and disputes over troop levels in Iraq and Afghanistan. Secretaries have also been central in debates over nuclear posture with inputs from United States Strategic Command and arms control agreements like the Strategic Arms Reduction Treaty and New START Treaty. Congressional oversight probes by committees including the House Armed Services Committee and Senate Armed Services Committee have shaped resignations and reforms, while interactions with Presidents—such as during the Nixon administration, Reagan administration, George W. Bush administration, and Obama administration—have highlighted civil-military tensions, policy disagreements, and the evolution of defense priorities.
