Following World War II most of the class had their AA and [[anti-submarine warfare]] (ASW) armament upgraded. The 40&nbsp;mm and 20&nbsp;mm guns were replaced by two to six [[3"/50 caliber gun|{{convert|3|in|0|adj=on}}/50 caliber guns]] in up to two twin and two single mountings. One depth charge rack was removed and two [[Hedgehog (weapon)|Hedgehog]] ASW mortar mounts added. The K-guns were retained. Nine additional (for a total of 35) ships were converted to radar picket destroyers (DDR) in the early 1950s; these typically received only one 3-inch twin mount to save weight for radar equipment, as did the wartime radar pickets. Nine ships were converted to escort destroyers (DDE), emphasizing ASW. {{USS|Carpenter|DD-825|2}} was the most thorough DDE conversion, with 4 [[3"/70 Mark 26 gun|3-inch/70 caliber]] guns in twin enclosed mounts, two [[Weapon Alpha]] launchers, four new 21-inch torpedo tubes for the [[Mark 37 torpedo|Mark 37 ASW torpedo]], and one depth charge rack.{{sfn|Friedman|2004|pp=510–513}}
