Childs (AVD 1).
In 1938, the Navy
perceived a need for fast tenders that could be deployed as mobile bases for squadrons of PBY patrol bombers. On 1 July, it reclassified two Clemson
-class flush deckers, Childs
, and took them in hand for conversion, removing their two forward stacks and replacing their two forward boilers with fuel tanks which, together with voids, gave them a capacity approximately 50,000 gallons of fuel. Their torpedo tubes, waist guns and 3-inch anti-aircraft gun were also removed and the bridge superstructure was extended aft to where the forward stacks had been to provide quarters for the squadron. A light crane was stepped amidships and aircraft servicing boats were carried in davits.

Their conversion was regarded as a success, leading to five more conversions authorized in 1939 and seven more in 1940.
Concurrently, on 26 October 1939, the name ship of the 1,766-ton Barnegat (AVP 10) class was laid down. Initially, the first seven flush-deckers were also designated AVP, with hull numbers 14–20 in sequence after the first four Barnegats. The designation was later changed to AVD, encompassing all fourteen ships.
One AVD and two ex-AVDs were lost during or immediately after World War II:
wsa awarded the Presidential Unit Citation for service in the Southwest Pacific, 20 June–16 October 1942.
Five other ships received ten Presidential Unit Citations while attached to the USS Bogue (CVE 9) hunter-killer task group in the Atlantic in 1943: Belknap, Clemson (two awards), George E. Badger (three awards), Greene and Osmond Ingram (three awards).
Six AVDs were converted again as high-speed transports (APDs
