Mopang was a Sub Boats type (EFC Design 1023) cargo steamship built in 1920 by the Submarine Boat Co shipyard in Newark, New Jersey owned by Electric Boat Company /later General Dynamics/. The ship was produced as part of a special program of the US Shipping Board that provisioned 150 identical ships to compensate for the losses from the war. The vessel sank on July 1, 1921^[2] after hitting a mine near the port of Burgas.
