From the spring of 1942, the General Board of the US Navy brought up a new fleet destroyer design for consideration. The design was expected to improve on the existing 2,200-ton Sumner class by raising the top speed from 36.5 to 38 knots with a moderate increase of 300 tons in displacement. This began a series of design studies that evaluated the potential characteristics of an improved Sumner/Gearing class. By the end of 1948, the design was drastically different from the destroyer envisioned 6 years before and formed the basis for the Mitscher class destroyer leaders.
