The Allen M. Sumner class was a group of 58 destroyers built by the United States during World War II. Another twelve ships were completed as destroyer minelayers. Often referred to as simply the Sumner class, this class was characterized by their twin 5"/38cal-gun mounts, dual rudders, additional anti-aircraft weapons, and many other advancements over the previous Fletcher class. The Sumner design was extended 14 feet (4.3 m) amidships to become the Gearing class, which was produced in larger numbers.

Completed in 1943–45, four were lost in the war and one was damaged so badly it was scrapped, but the surviving ships served in the US Navy into the 1970s. After being retired from the US fleet, 29 of them were sold to other navies, where they served many more years. Two still exist as museum ships, one in South Carolina, and one in Taiwan.

Famous quotes containing the words sumner, class and/or destroyer:

    through the Sumner Tunnel,
    trunk by trunk through its sulphurous walls,
    tile by tile like a men’s urinal,
    slipping through
    like somebody else’s package.
    Anne Sexton (1928–1974)

    To avoid the consequences of posterity the mulattos give the blacks a first class letting alone. There is a frantic stampede white-ward to escape from Jamaica’s black mass.
    Zora Neale Hurston (1891–1960)

    The supreme, the merciless, the destroyer of opposition, the exalted King, the shepherd, the protector of the quarters of the world, the King the word of whose mouth destroys mountains and seas, who by his lordly attack has forced mighty and merciless Kings from the rising of the sun to the setting of the same to acknowledge one supremacy.
    Ashurnasirpal II (r. 883–59 B.C.)
