The "Fletcher"-class was the first generation of destroyers designed after the series of Naval Treaties that had limited ship designs heretofore. The growth in the design was in part a response to the challenge that had dogged U.S. Navy designs in coping with long range operations in the Pacific Ocean. They were also to carry no fewer than five guns and ten deck-mounted torpedo tubes on the centerline, allowing them to meet any foreign design on equal terms. Compared to earlier designs, the "Fletcher"s were large, allowing them to adapt to evolving defensive priorities through the addition of two 40 mm Bofors quadruple mount anti-aircraft guns as well as six 20 mm Oerlikon dual AA gun positions. This addition to the AA suite required the deletion of the forward quintuple torpedo mount, a change done under the 4 April 1945 anti-"kamikaze" program.
