Service history

Cebu's special mission was providing shops and trained men for the repair of internal combustion engines, but through the course of the war, her men performed a variety of tasks, ranging from the repairing of ship's clocks to major work on battleships. She arrived at Manus in the Admiralty Islands 10 September 1944. At this fleet base, she prepared small craft and larger ships for their role in the Philippine operations, working many times around the clock in order to insure the readiness of ships vital to the invasion assaults.[3]

Mount Hood explosion

At Manus on 10 November 1944, Cebu was anchored only 800 yd (730 m) from Mount Hood when the ammunition ship exploded, showering Cebu's decks with bomb fragments and heavy projectiles. Five of her men were killed and six wounded, but quick work prevented serious damage to the ship itself. She was able to continue her work without interruption, preparing ships for the Lingayen and Iwo Jima assaults.[3]

Philippines and occupation duty

Cebu was stationed at Ulithi from 22 January to 12 February 1945, when she sailed for San Pedro Bay. Her work continued at a furious rate as victims of suicide attacks required immediate repairs. Her services to small craft at Leyte continued until 21 September, when she sailed for occupation duties at Okinawa and Japan until 11 March 1946.[3]

Operation "Crossroads"

Cebu prepared at Pearl Harbor from 29 March to 11 May 1945, for her role supporting the atomic tests of Operation Crossroads at Bikini and Kwajalein in the summer of 1946.[3]


She arrived at San Diego, California, 28 September, and was placed out of commission in the Pacific Reserve Fleet at Stockton, California, 30 June 1947.[3]

On 4 August 1961, Cebu was transferred to the National Defense Reserve Fleet at Suisun Bay, California. Her name reverted to Francis P. Duffy and she was struck from the Naval Register on 1 September 1962.[2]


On 18 October 1973, Francis P. Duffy was sold to Zidell Explorations Inc., for $151,899.99 to be scrapped. She was withdrawn from on 14 November 1973.[2]


Cebu received one battle star for World War II service.[3]
