1798 – Congress established the Department of the Navy on this date in 1798, however, the United States Navy traces its origins to the Continental Navy, which the Continental Congress established on 13 October 1775 by authorizing the procurement, fitting out, manning, and dispatch of two armed vessels to cruise in search of munitions ships supplying the British Army in America. In 1972 Chief of Naval Operations Admiral Elmo R. Zumwalt authorized recognition of the 13 October 1775 date as the Navy’s “official” birthday.
