Alcoa Steamship Company, Inc.

Alcoa Steamship Company, Inc. (ALCOA is an acronym for "Aluminum Company of America") started in 1917 due to the shortage of ships during the World War I. At the start foreign flag ships (non US Flagged) were used until just before WWII. From 1940 till 1969 Alcoa operated US flag vessels before returning to operate foreign flag vessels again. The company is still in operation but they are using chartered vessels at the present time. They are located in Pittsburgh PA.
