n 1877, the U.S. Navy purchased the fast steam yacht Stiletto from the Herreshoff Manufacturing Company of Bristol, Rhode Island, for "automobile" torpedo experiments in Narragansett Bay. The submarine service was in its infancy, and interest in the self-propelled torpedo as an undersea weapon flourished. Herreshoff's fast, steam-powered boats were the first of the delivery platforms accepted by the U.S. Navy Department for experiments at the Newport Naval Torpedo Station and service during the Spanish-American War.
