Seven WWI era U.S. Navy transports had two smokestacks and four masts. Five were taken into service during the war. Three of these were former German passenger liners seized in 1917 and commissioned later in that year. One of them was torpedoed and sunk during the conflict. Two U.S. flag liners were placed in commission in 1918, after initially operating with civilian crews under U.S. Army charter. The remaining two ships, which had spent the war in Germany, were taken over early in 1919 to convey U.S. service personnel home from Europe.
These seven ships varied significantly in size, with the largest having nearly twice the tonnage as the smallest. They can be readily separated into three groups: three large ex-German ships of over 20,000 gross tons; two ex-German ships of about 16,000 gross tons; and two American liners of about 12,000 tons.
Two of the larger ships were somewhat similar in appearance, though stack spacing and other design elements were different. The third ship had an additional superstructure level. The middle group were also fairly close in appearance, while the smaller American liners were nearly identical. The ships commissioned in 1917-1918 wore Navy-type color schemes: grey overall, with most having pattern camouflage during much of 1918. The 1919 acquisitions were both painted in civilian colors during their Naval service.
