Type C4-class ship
 The Type C4 class ship were the largest cargo ships built by the United States Maritime Commission (MARCOM) during World War II. The design was originally developed for the American-Hawaiian Lines in 1941 but in late 1941 the plans were taken over by the MARCOM. Seventy-five ships were built as cargo and troopships in three shipyards: Kaiser Richmond CA (35 ships) Kaiser Vancouver WA (20 ships) and Sun SB & DD in Chester PA (20 ships).
