The SS Faith was the first concrete ship built in the United States.

It was constructed by the San Francisco Shipbuilding Company in 1918 owned by William Leslie Comyn.

[1] The Steam Ship (SS) Faith launched on March 14, 1918,[2] from Redwood City, California.

[1] "[...] said William Leslie Comyn [...] he likewise pointed out the lack of steel-making plants and shipyards on the West Coast.

[...] He was convinced that a 5,000-ton concrete freighter could be operated at a profit and on 3 September 1917 he solicited contractual support from USSB to build "five reinforced concrete steamers" [...] On speculation, then, his firm began to build the Faith at Redwood City, California"[5] The first journeys were to Honolulu, Balboa, Callao, Valparaíso and New York.
