The Navy Birthday is one of the two Navy-wide dates celebrated annually – Navy Birthday and Navy Day.
The United States Navy was originally established as the Continental navy on 13 October 1775, when the Continental Congress authorized the procurement, fitting out, manning, and dispatch of two armed vessels to cruise in search of munitions ships supplying the British Army in America. The legislation also established a Naval Committee to supervise the work. All together, the Continental Navy numbered some fifty ships over the course of the war, with approximately twenty warships active at its maximum strength.
