The Gearing class was a series of 98 destroyers built for the U.S. Navy during and shortly after World War II. The Gearing design was a minor modification of the Allen M. Sumner class, whereby the hull was lengthened by 14 ft (4.3 m) at amidships, which resulted in more fuel storage space and increased the operating range.

The first Gearings were not ready for service until mid-1945 and saw little service in World War II. They continued serving, with a series of upgrades, until the 1970s. At that time many were sold to other nations, where they served many more years.
