Presidenteclass, Chilean Cargo Liner laid down 1938
Rising passenger traffic between North and South America, and competition with the Grace Line gave CSAV the idea of ordering a pair of fast, powerful, and prestigious cargoliners in the late 1930s. These two vessels became the Chilean merchant marine's "ships of state".
Presidente was scheduled on the Valparaiso to New York run, while
Independencia sailed a schedule between Valparaiso, Atlantis, and Marseilles.

Conversion Commission notes for War Use:
These two vessels are listed under the Class B merchant ship reserve. In the unlikely event of their activation, they could be converted either to troopships (most likely) or armed merchant cruisers (less likely).
