Service history[edit]

L-class submarines USS L-3 (SS-42), USS L-11, USS L-10 (SS-50), USS L-4 (SS-43), and USS L-9 (SS-49) alongside their submarine tender in British waters in 1918. The "A" (for "American") was added to avoid confusion with British L-class submarines.

Assigned to the Atlantic Submarine Flotilla, L-11 operated along the East Coast developing new techniques of undersea warfare until April 1917. After the United States's entry into World War I, submarines were needed to protect Allied shipping lanes to Europe, and L-11 departed Boston, Massachusetts on 4 December to undertake the task. Following a period of patrol and repair in the Azores, the submarine arrived Ireland in mid-February 1918 to Join Submarine Division 5 (SubDiv 5) in anti-submarine patrol off the British Isles. For the next nine months, she ranged shipping lanes, sighting enemy U-boats on three occasions. On 11 May, she made a torpedo attack on an enemy submarine with inconclusive results.

After the Armistice with Germany, L-11 operated out of the Isle of Portland, England, until 3 January 1919 when she sailed for the United States. Arriving Philadelphia, Pennsylvania, on 1 February, she operated off the East Coast for the next four years developing submarine warfare tactics. L-11 decommissioned at Hampton Roads, Virginia, on 28 November 1923, and was scrapped on 28 November 1933.
