USS Aramis (SP-418/PY-7) was a converted yacht that served the United States Navy from 1917 to 1933, primarily as a patrol vessel and later as an auxiliary support craft. Built and acquired during World War I, she was commissioned at the New York Navy Yard on 2 November 1917, designated SP-418. She measured a length typical of yachts of her era, with a hull modified for patrol and experimental purposes. Initially stationed at the mouth of New York Harbor, Aramis performed patrol duties, monitoring net defenses and engaging in anti-intrusion activities. Notably, she intercepted private craft that crossed restricted areas, arresting intruders and maintaining security during wartime. In November 1917, she was assigned to patrol operations near Sandy Hook and later took part in experimental anti-submarine efforts, including the installation of primitive underwater detection systems and the deployment of early depth charges. Throughout her service, Aramis was involved in various patrols, convoy escort missions, and anti-submarine operations. She played a role in rescuing survivors from torpedoed vessels, such as the Norwegian steamer Sommerstad, and participated in experiments with listening gear, including testing with Lt. Comdr. Chester W. Nimitz aboard in early 1918. Her operational duties extended to escorting submarines and engaging in patrols along the U.S. East Coast. In 1918, she briefly served as a flagship of a battleship division, but engine troubles limited her effectiveness. After the war, she was used as a tender and houseboat off Cuba, supporting survey operations conducted by Nokomis. She was reclassified as PY-7 in 1920 and remained in reserve until her decommissioning on 6 October 1921. Subsequently, she served as a district craft and was stationed at Key West, Florida, until 1933. Stripped of useful equipment and sold in 1933, USS Aramis’s career highlights include her role in anti-submarine experimentation, patrol security during WWI, and support for naval survey operations. Her service exemplifies the versatility and adaptation of yachts converted for wartime naval use.
