USS Aramis (SP-418/PY-7) was a yacht acquired by the United States Navy during World War I which served as a patrol boat off New York City, was then fitted with an experimental "underwater detection system" and depth charges as an anti-submarine vessel, and was briefly the flagship of a battleship squadron. She ended her career as a tender and houseboat to a survey vessel off the coast of Cuba, until disposed of in 1933.
