Ailanthus (YN-57) was laid down on 17 November 1942 at Everett, Washington, by the Everett-Pacific Shipbuilding & Dry Dock Company; launched on 20 May 1943; sponsored by Miss Billie Jean McNatt; and placed in commission at Seattle, Washington, on 2 December 1943.
The net tender completed fitting out and, during the second half of December, conducted shakedown training. On the last day of 1943, she reported for duty in the 13th Naval District. On 20 January 1944, she was reclassified a net laying ship and redesignated AN-38.
Early in February, Ailanthus moved north to Pleasant Island, Alaska, where she arrived on 4 February. Reassigned that same day to Service Squadron 6, U.S. Pacific Fleet, she began to carry out net laying duties.
However, her career proved very brief. Having delivered a cargo of perforated steel plating (Marston Mat) to a Navy Seabee contingent building an airfield on the westernmost island of Attu, Ailanthus was caught in a violent winter storm, and on 26 February 1944, slipped her anchorage and was driven hard aground, suffering extensive damage. While still stranded, Ailanthus was reassigned to the newly constituted 17th Naval District (the Alaskan portion of the old 13th Naval District to which she had originally been assigned). Finally, she was declared a total loss, and her name was struck from the Navy List on 9 June 1944.
