The ships were built on a "cost-plus" basis, and Jahncke contracted to build 12 of the 3,500 ton ships, as well as 12 steel ships of 5,000 tons each. As many as 2,000 men were employed in Madisonville shipyards between 1917 and 1918, with a weekly payroll of $80,000. The picture came from a 75th anniversary yearbook put out by Jahncke Services in 1950.
