The Gridley-class destroyers were a class of four 1500-ton destroyers in the United States Navy. The initial two ships were laid down on June 3, 1935 and commissioned in 1937. The second two were laid down in March 1936 and commissioned in 1938. Based on the Mahan-class destroyer, they had the same hull but had only a single stack and mounted sixteen torpedo tubes. Their powerplants were also a significant upgrade from the Mahan class and made the highest speed ever recorded for a United States Navy destroyer.
