The USS Dreadnought (SP-584), later known as USS SP-584, was a United States Navy patrol vessel in service from 1917 to 1919. Originally constructed as a private fast "runabout" motorboat, she was built by R. Bigelow at Monument Beach, Massachusetts, in either 1916 or 1917. The vessel's design emphasized speed and agility, suitable for patrol duties, though specific dimensions are not detailed on the Wikipedia page. In May 1917, the U.S. Navy acquired her from her owner, Eldon B. Keith of Brockton, Massachusetts, to support wartime naval operations. She was officially commissioned into Navy service on 20 October 1917 as USS Dreadnought (SP-584). During her naval career, she was assigned to the 5th Naval District, where she performed patrol duties along the U.S. coastline, primarily tasked with harbor security and coastal patrols during World War I. In 1918, the vessel was renamed USS SP-584, reflecting her identification number and to avoid confusion with other ships. Her service in the Navy was relatively brief, ending in June 1919, when she was returned to her owner on June 6 of that year. The vessel's primary significance lies in her role as a patrol craft during a critical period of American maritime security efforts in World War I. It is noteworthy that USS Dreadnought (SP-584) should not be confused with the similarly named tug USS Dreadnaught (ID-1951), which was in commission at the same time. This vessel exemplifies the small, privately built motorboats that the U.S. Navy adapted for patrol service during wartime, contributing to coastal defense and maritime security during a pivotal era.
