New Orleans Navy Yard

YFD-2 was towed to her station in the Navy Yard near New Orleans at Algiers, New Orleans, Louisiana on 6 November 1901. It took four steam tugboats: the Orion, Taurus, Peerless, and Volunteer to tow YFD-2 from Maryland to New Orleans. YFD-2 was a new state of the art machine for its time. USS Stranger with the Louisiana governor, William Wright Heard and the New Orleans mayor, Paul Capdevielle where there to greet the arrival. A New Orleans parade was held to celebrate the arrival. The first United States Navy ship repaired was the 11,565-ton battleship USS Illinois, a pre-dreadnought battleship in January 1902. Next YFD-2 repaired the 300-foot (91 m) long transfer boat Carrier. In 1903 she repaired the Norwegian cargo ship Telefon. YFD-2 remained in New Orleans until towed to Pearl Harbor, Territory of Hawaii. The dock arrived in Pearl Harbor on 23 August 1940, before World War II. She departed New Orleans on 19 March 1940 after modification to make her sea worthy for the 6,000-mile (9,700 km) travel. To go through the Panama Canal she was taken apart at Cristóbal, Colón, the Canal was only 100 feet (30 m) wide at that time and the 128-foot (39 m) wide drydock would not pass. The sections were towed through the Canal and reassembled at Balboa, Panama.^[2][3]

Attack on Pearl Harbor

YFD-2 was repairing the destroyer USS Shaw on 7 December 1941 during the attack on the harbor. YFD-2 and Shaw were hit and damaged in the attack by Japanese dive bombers. Shaw also damaged YFD-2 with the explosion of her forward ammunition magazines stores. Both ships were repaired and put back in service. On 9 January 1942 YFD-2 had the water pumped out of her pontoon tanks and was raised for repair. When the repairs were completed she was put back in service in May 1942. The Pacific Bridge Company was give charge for the repairs of YFD-2. Divers had to repair more than 200 holes in YFD-2 to float her again. Repaired, the YFD-2 raised the USS Shaw for 10 days of repairs to install a new temporary bow so Shaw could return to the naval shipyard at Mare Island at Vallejo, California for final repairs. YFD-2 was used for salvaging and repairing many of ships damaged on 7 December 1941, as she could raise any ship here, other than the large new battleships.

She continued repair work throughout World War II at Pearl Harbor. After the war YFD-2 was struck from the Naval Register on 28 January 1947. She was sold on 30 March 1948 for private use.^[4][5][6][7]
