She was commissioned on 26 November 1917. Service history United States Navy Stockton spent the last year of World War I assigned to convoy escort and antisubmarine warfare duty, operating from Queenstown (now Cobh), Ireland. During that time, she engaged an Imperial German Navy U-boat on at least one occasion. On 30 March 1918, she and the destroyer were escorting the troopship St. Paul on the Queenstown-Liverpool circuit, when Ericsson opened fire on a German submarine. The submerged submarine launched a torpedo at Stockton almost immediately thereafter, and the destroyer narrowly evaded it. The two destroyers dropped patterns of depth charges, but the U-boat managed to evade their attack and escaped. Later that night, Stockton collided with the ferry near South Stack Light.
