''McDougal'' was laid down by Bath Iron Works of Bath, Maine, in July 1913 and launched in April 1914. The ship was a little more than in length, just over abeam, and had a standard displacement of . She was armed with four guns and had eight torpedo tubes. ''McDougal'' was powered by a pair of steam turbines that propelled her at up to . After her June 1914 commissioning, ''McDougal'' 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, and carried 6 crewmen from a sunken Dutch cargo ship to Newport, Rhode Island. After the United States entered World War I in April 1917, ''McDougal'' was part of the first U.S. destroyer squadron sent overseas. Patrolling the Irish Sea out of Queenstown, Ireland, ''McDougal'' made several unsuccessful attacks on U-boats, and rescued survivors of ships sunk by the German craft. After a collision with a British cargo ship in February 1918, ''McDougal'' was under repair until mid-July, and afterwards, operated out of Brest, France. Upon returning to the United States after the war, ''McDougal'' conducted operations with the destroyers of the Atlantic Fleet until August 1919, when she was placed in reserve, still in commission. After a brief stint of operations in mid 1921, she was placed in reserve until she was decommissioned at Philadelphia in May 1922. In June 1924, ''Ericsson'' was transferred to the United States Coast Guard to help enforce Prohibition as a part of the "Rum Patrol". She operated under the name USCGC ''McDougal'' (CG-6) until May 1933, when she was returned to the Navy. In November she dropped her name to free it for a new destroyer of the same name, becoming known only as ''DD-54''. She was struck for the Naval Vessel Register in July 1934 and sold for scrapping in August. == Design and construction == ''McDougal'' was authorized in March 1913 as the fourth of six ships of the , which was an improved version of the s authorized in 1911.
