The ship was the second US 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. ''O'Brien'' was laid down by William Cramp and Sons of Philadelphia in September 1913 and launched in July 1914. After her May 1915 commissioning, ''O'Brien'' sailed off the east coast and in the Caribbean. She was one of seventeen destroyers sent out to rescue survivors from five victims of German submarine 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'' revisited 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 and sold for scrapping in April. ==Design and construction== ''O'Brien'' was authorized in March 1913 as the lead ship of the , which was an improved version of the s authorized in 1911.
