Construction West Madaket was built in 1918 as a commercial cargo ship at Seattle, Washington by the Skinner and Eddy Corporation. Launched on 5 October 1918, she was acquired by the U.S. Navy for World War I service upon completion on 31 October 1918, assigned naval registry Identification Number (Id.

Voyaging via the Panama Canal, she arrived at New York City on 16 December 1918 and departed on 22 December 1918, bound for Europe. She made port at Falmouth, England, on 5 January 1919 and pushed on, that same day, for Rotterdam, the Netherlands, where she discharged her cargo until 23 January 1919. Returning to New York on 9 February 1919, West Madaket loaded 6,841 tons of general cargo and made a voyage to Le Verdon-sur-Mer, France, returning to New York on 28 April 1919. West Madaket was decommissioned on 8 May 1919 at Newport News, Virginia, and was transferred to the United States Shipping Board on the same day.
