SS Clifford D. Mallory was a Liberty ship built in the United States during World War II. She was named after Clifford D. Mallory, a vice president of the Mallory and Clyde Lines, a Shipping Board Emergency Fleet Corporation officer, and founder of C.D. Mallory & Co.

Construction

Clifford D. Mallory was laid down on 30 January 1943, under a Maritime Commission (MARCOM) contract, MCE hull 952, by the Bethlehem-Fairfield Shipyard, Baltimore, Maryland; she was launched on 11 March 1943.^[1]^[2]

History

Conversion to minesweeper

On 1 June 1955, she was withdrawn from the reserve fleet and transported to the Mississippi Shipping Co., in Mobile, for conversion to a minesweeper. The conversion included installing equipment for remote control propulsion, adding a 1,000 U.S. gal/min (0.063 m³/s) ballesting pump, and changing buoyant material in all five holds. She had been assigned the new classification of YAG, Auxiliary Service Craft, Miscellaneous, and the hull number 49, but after conversion she was not acquired by the USN and was placed back into the Reserve Fleet, in Mobile, 17 January 1956.^[5]^[4]
