which branch of the service was once known as the revenue marine
United States Revenue Cutter Service The United States Revenue Cutter Service was established by an act of Congress (1 Stat. 175) on 4 August 1790 as the Revenue-Marine upon the recommendation of Secretary of the Treasury Alexander Hamilton to serve as an armed customs enforcement service. As time passed, the service gradually gained missions either voluntarily or by legislation, including those of a military nature. It was generally referred to as the Revenue-Marine until July 1894, when it was officially renamed the Revenue Cutter Service.
United States Department of the Navy The United States Department of the Navy (DoN) was established by an Act of Congress on April 30, 1798 (initiated by the recommendation of James McHenry),[1] to provide a government organizational structure to the United States Navy, the United States Marine Corps (from 1834 onward) and, when directed by the President (or Congress during time of war), the United States Coast Guard, as a service within the Navy,[2] though each remain independent service branches. The Department of the Navy was an Executive Department and the Secretary of the Navy was a member of the President's cabinet until 1949, when amendments to the National Security Act of 1947 changed the name of the National Military Establishment to the Department of Defense and made it an Executive Department. The Department of the Navy then became, along with the Department of the Army and Department of the Air Force, a Military Department within the Department of Defense: subject to the authority, direction and control of the Secretary of Defense.
