Neponset made one voyage across the Atlantic carrying general cargo, horses, and veterinary replacement personnel. She cleared New York for France on 13 November 1918, arriving at Bordeaux on the 30th. She returned to the US, was decommissioned on 4 February 1919, and was returned to the United States Shipping Board. Later renamed again to Shawmut and Susan V. Luckenbach.
