Modifications
24 were designated for conversion to Radar Picket Destroyers by removing 1x5 torpedo tubes and altering the internal arrangement to make space for SP radar, IFF, and ECM and the men to man them. Some of these were further modified by removing the remaining torpedo bank and replacing it with 1x4 40mm guns.


The Gearings, completed in 1944-45, were a development of the Allen M. Sumner class that added 14' to the length, which improved speed, range, and sea keeping and eliminated the major stress points in the hull. The larger hulls were able to support an ample battery of antiaircraft guns while retaining a powerful torpedo armament. 152 were ordered but many were later canceled. About 45 were completed before the Japanese surrender but only the six shown below arrived in time to see significant service. As the most advanced U.S. destroyer design built during the war, they saw long postwar service, some serving into the 1980s. In this respect they were the post-World War II equivalent of the "flush-deckers."
