PROTOTYPE
Manley, ex-Destroyer No. 74 and DD 74, was the first Caldwell-class destroyer commissioned—the first flush-decker. Converted as the APDs prototype APD in 1938–39, she lost her two forward boilers in favor of quarters for troops. She also lost forward stacks, her 4-inch guns were replaced by 3-inch rapid-fire dual purpose guns and her four banks of torpedo tubes were replaced by davits for Higgins landing craft. She also stowed four machine guns on carts, one 75mm pack howitzer, ten boat guns and ammunition for a total gain of 33 tons.

FOLLOW-ON CONVERSIONS
Seventeen Wickes-class and fourteen Clemson-class destroyers were converted as APDs.
Of the latter, six had previously been converted as seaplane tenders (AVDs): George E. Badger, Clemson, Goldsborough, Belknap, Osmond Ingram and Greene.

DECORATIONS
Five of the six ex-AVDs received ten Presidential Unit Citations, all while attached to the USS Bogue (CVE 9) hunter-killer task group in the Atlantic in 1943 before their conversion as APDs: Belknap as AVD 8; Clemson, two awards as
