Manta (No. 2036), originally built for the Clyde Steamship Co., was launched in 1916 by the Chicago Ship Building Co., South Chicago, III.; and acquired and commissioned by the Navy 8 December 1917.
Manta, a NOTS cargo ship, plied the waters of the eastern Atlantic and the Caribbean until mid‑July 1918. She then conducted two round‑trip voyages to Europe as a mine carrier. On 30 October 1918 during the second return voyage, she was damaged in a storm and was towed to Norfolk. After extensive repairs she was decommissioned 13 March 1919 and returned to her owner.
