The Navy Birthday is on October 13 and celebrates the establishment of the US Navy in 1775.
On October 13, 1775, the United States Navy was established. The day is celebrated as the birthdate of the American Navy.
The United States Navy originated over 240 years ago as the Continental Navy. The then Continental Congress authorized 2 armed vessels to search for ships supplying the British army with weapons and ammunition during the American Revolutionary War (1775–1783).
When the war ended, the Continental Navy was dismantled, but pirate threats to American merchant shipping led President George Washington to establish the Naval Act of 1794, creating a permanent standing US Navy.
