USS O'Brien (Destroyer No.
51/DD-51) was laid down by William Cramp & Sons of Philadelphia in September 1913 and launched in July 1914.
The ship was the second U.S. Navy vessel named in honor of Jeremiah O'Brien and his five brothers, Gideon, John, William, Dennis, and Joseph who, together on the sloop Unity, captured a British warship during the American Revolutionary War.

After O'Brien's May 1915 commissioning, she sailed off the east coast and in the Caribbean.
She was one of the U.S. destroyers sent out to rescue survivors from five victims of German submarine U-53 off the Lightship Nantucket in October 1916.
After the United States entered World War I in April 1917, O'Brien was sent overseas to patrol the Irish Sea out of Queenstown, Ireland.

After returning to the United States in January 1919, O'Brien returned to European waters in May to serve as one of the picket ships for the NC-type seaplanes in the first aerial crossing of the Atlantic.
O'Brien was decommissioned at Philadelphia in June 1922.
She was struck from the Naval Vessel Register in March 1935 sold for scrapping in April.
