Three WWI era U.S. Navy transports had four smokestacks. All were originally German passenger liners completed in 1901-1906 and seized by the U.S. Government in 1917. They were similar in size and appearance, with long, low superstructures and stacks spaced amidships in groups of two, in the German style (British four-stack liners had their funnels evenly spaced). Two had three masts and one had two.
This page features a table (with links to individual ships) of World War I era U.S. Navy transports with four smokestacks, plus one photograph of every ship in this group.
