The Somers were completed in 1938-39. Basically improved Porters, they were designed for the same role, as flotilla leaders. The ships were originally proposed to be repeats of the Porters, but there had been substantial improvements in machinery and the design was modified accordingly. Enough weight was saved by simplifying the superstructure to permit shipping a third torpedo bank, but no reloads were provided.

Like almost every other American destroyer class preceding Fletcher, they were top-heavy and close to their stability limit. This limited the amount of additional light antiaircraft that could be shipped during the war.
