The Benhams were completed during 1938-1940, making them among the most modern destroyers with which the U.S. Fleet started the war. They were heavily armed, had great hull strength, and were extremely fast. 

At the time their design was under development, in 1935, the Navy had become so concerned with the increasing difficulty of fitting the desired firepower on a treaty-limited 1500-ton displacement that serious consideration was given to abandoning the heavy dual-purpose gun mounts. However, the Fleet insisted on the dual-purpose armament, and the design chosen was essentially an improved Gridley. The ships used three higher-pressure boilers in place of the four boilers of the earlier class, as well as more powerful machinery, and their displacement ended up being well over the 1500-ton limit. This no longer mattered much, as the 1936 London Treaty substituted restrictions on total destroyer tonnage for restrictions on individual ship tonnage. 

They were expensive for destroyers, costing nearly $5 million dollars at the time.
