Seal of the United States Department of the Navy
The 'United States Department of the Navy' was established by an
Act of Congress on
April 30,
1798, to provide administrative and technical support, and civilian leadership to the
United States Navy and the
United States Marine Corps (and when directed by the Congress or President, the
United States Coast Guard). It is headed by the
Secretary of the Navy, also known as the SECNAV in naval jargon. He is assisted by an
Undersecretary of the Navy. The Department was a
cabinet position, along with the
War Department which contained the
US Army until
1947 when the
National Military Establishment was formed. The National Military Establishment was later renamed
Department of Defense (DOD) in
1949. The Department of the Navy then became a component of the DOD.
The Department of the Navy consists of
Executive offices, mostly located within
Washington, DC and is responsible for the
recruiting of military and civilian personnel, organizing, supplying, equipping, training, and the mobilization and demobilization of the navy and its personnel and assets. The Department also oversees the construction, outfitting and repair of naval ships, aircraft, equipment and facilities.
The Department comprises two
uniformed services, also called the
sea services, the
United States Navy and the
United States Marine Corps.
