The Eries were gunboats built in 1936 in Navy yards for the purpose of "showing the flag" at distant stations in peacetime ("peace cruisers") and for escort or antiaircraft duty in wartime. They were a tight design meant to exploit a loophole in the naval disarmament treaties, which exempted unarmored gunboats of 2000 tons or less, speed of 20 knots or less, and armament under 6.1" from restrictions. They were rather odd ducks, with the armament of a small light cruiser and the antisubmarine gear of a destroyer. They were designed to be fitted with a 3" (76mm) armor belt on commencement of hostilities, which apparently took place early in the war. However, their speed was much too slow for most of the roles envisioned for them.
