The Patokas were ordered for the Navy by the U.S. Shipping Board in the fall of 1918, when it was thought the First World War would continue for another year. They were completed in 1919-1922. In some ways they were a step backwards from the Kanawhas, being built to roughly the same standards as the best commercial tankers of the time.

They were quite elderly by the start of the war, and were usually not equipped for underway replenishment, since their low speed made it impossible for them to keep up with a task force.
