    Dictionary of American Naval Fighting Ships History:


    Any of numerous large, vigorous, spiny-finned fishes including some highly esteemed for sport and food.

    The first Tuna (SP-664)—a motor yacht built in 1911 at Baltimore, Md., by the Neilson Yacht Building Co.—was acquired under free lease from Mr. Edward L. Welch of Philadelphia, Pa., on 11 June 1917 and was commissioned on 12 June 1917. During World War I, Tuna was assigned to the Block Island section base in the 2d Naval District and patrolled the coastline between Long Island and Martha's Vineyard. On 11 January 1919, she was returned to her owner, and her name was struck from the Navy list.
