Many "Wickes"-class destroyers were converted to other uses, starting as early as 1920, when 14 were converted to light minelayers (hull classification symbol DM). Six of these were scrapped in 1932, and replaced by five additional conversions. Another four were converted to auxiliaries or transports at that time. Four "Wickes"-class DM conversions and four "Clemson"-class DM conversions survived to serve in World War II. During the 1930s, 23 more were scrapped, sold off, or sunk as targets. This was mostly due to a blanket replacement of 61 Yarrow-boilered destroyers 1930-31, as these boilers wore out quickly in service. Flush-deckers in reserve were commissioned as replacements.
