Department of the Navy

Department of the Navy. Established by an Act of Congress in 1798, it is a military department within the United States Department of Defense responsible for the naval warfare and expeditionary forces of the United States. It oversees the United States Navy and the United States Marine Corps, and during wartime, it also assumes control of the United States Coast Guard. The department's leadership, headquartered at The Pentagon, formulates policy and manages resources to maintain global maritime superiority.

History

The department's origins trace to the Continental Navy, formed during the American Revolutionary War. Following the ratification of the United States Constitution, the Naval Act of 1794 authorized the construction of the first frigates, leading to the formal establishment of the department by President John Adams. Key historical milestones include its role in the War of 1812, the American Civil War under Secretary Gideon Welles, and its massive expansion during World War II under Secretary Frank Knox and James Forrestal. The National Security Act of 1947 subsequently placed it within the newly created United States Department of Defense, a reorganization further cemented by the Goldwater–Nichols Act in 1986.

Organization

The department is structured under the civilian leadership of the United States Secretary of the Navy, who reports directly to the United States Secretary of Defense and the President of the United States. Its principal military advisors are the Chief of Naval Operations and the Commandant of the Marine Corps, who serve as members of the Joint Chiefs of Staff. Major subordinate commands include United States Fleet Forces Command, United States Pacific Fleet, and United States Naval Forces Europe-Africa. The department also maintains a vast support apparatus including the Office of Naval Research, the Naval Criminal Investigative Service, and the United States Naval Academy.

Leadership

Civilian leadership is headed by the United States Secretary of the Navy, currently Carlos Del Toro, and the United States Under Secretary of the Navy, Erik Raven. Senior uniformed leadership consists of the Chief of Naval Operations, Admiral Lisa Franchetti, and the Commandant of the Marine Corps, General David H. Berger. These leaders are supported by other key officials such as the Assistant Secretary of the Navy for various portfolios and the Sergeant Major of the Marine Corps. The Vice Chairman of the Joint Chiefs of Staff, Admiral Christopher W. Grady, also hails from its ranks.

Components

Its two primary uniformed services are the United States Navy and the United States Marine Corps. The Navy's operating forces are organized into fleets like the United States Seventh Fleet and include assets such as aircraft carriers, submarines, and destroyers. The United States Marine Corps is organized into the Fleet Marine Forces under United States Marine Corps Forces Command and United States Marine Corps Forces Pacific. Other integral components include the United States Naval Reserve, the United States Navy Nurse Corps, the United States Marine Corps Reserve, and support establishments like Naval Air Systems Command and Space and Naval Warfare Systems Command.

Budget and funding

Funding is authorized annually through the National Defense Authorization Act and appropriated by Congress. The department's budget, one of the largest within the United States Department of Defense, finances personnel, operations and maintenance, research and development through agencies like the Defense Advanced Research Projects Agency, and procurement of major systems such as the Gerald R. Ford-class aircraft carrier and the Virginia-class submarine. Significant portions of the budget are also allocated to the Marine Corps Forces Special Operations Command and facilities worldwide, including Naval Station Norfolk and Marine Corps Base Camp Pendleton.

Responsibilities and functions

Its primary mission is to organize, train, and equip naval forces for the conduct of prompt and sustained combat operations at sea, including power projection and sea control. This encompasses a wide range of functions: maintaining nuclear deterrence via ballistic missile submarines, conducting amphibious warfare and expeditionary warfare, executing special operations through Naval Special Warfare Command, and ensuring freedom of navigation globally. The department also supports broader national objectives through humanitarian assistance, disaster relief operations, and scientific research conducted by the United States Naval Research Laboratory.
