The Treasuries were all named after former U.S. Secretaries of the Treasury (the Coast Guard falling under the Department of the Treasure in peacetime) and were completed in 1936-1937. Based on the hulls and machinery of the Erie class, their design emphasized long range rather than speed. They were originally constructed to carry a single seaplane, but the seaplane facilities had been replaced with depth charge tracks and throwers by the time war broke out in the Pacific. At $2.5 million apiece, the ships were regarded as highly cost-effective.

They were considered highly successful, particularly in the antisubmarine role. Though they served primarily in the Atlantic as convoy flagships, they were eventually transferred to the Pacific to serve as amphibious command ships.
