Auxiliary repair dock

The Auxiliary repair dock was a type Auxiliary floating drydock a type of floating drydock, which could, by design, provide drydock facility to damaged Navy vessels. Floating drydocks of this type were approximately 500-foot (150 m) long and weighted about 5,000 tons. The first Auxiliary repair dock was the USS ARD-1 built by the Pacific Bridge Company and completed in September 1934. ARD-1 was 2200 tons, 393 ft 6 in (119.94 m) long and could lift 2200 tons. ARD-1 was so successful that 30 ARDs docks were built, most completed between 1942 and 1944. ARD-2 and the next five ARD docks were larger at 3500 tons. and 485'8" (148.0m) long. ARD-1 was taken to a forward Naval base at Kerama Retto, Okinawa Island, to repair the many ships damaged by kamikaze attacks. ARD-1 made many temporary repairs to get ships back into action. Many other ARDs joined ARD-1 in this important task. This minimized the time ships were out of action for repairs.[1][2][3][4][5][6]

Floating drydocks, of this and other types, were capable of flooding themselves, opening up a bow door to permit a damaged vessel to enter. Once the damaged vessel was within the bounds of the floating drydock, and the door was closed, the water was pumped out of the floating drydock, permitting repair work to be performed on the damaged vessel. Such work in battle areas was often of a temporary nature, primarily to return the damaged vessel to seaworthy condition.

Once the damaged vessel was sufficiently repaired, the floating drydock was flooded, the door opened, and the repaired vessel allowed to depart for further duty or assignment.

While the damaged vessel was being repaired, the drydock was capable of providing the crew of the damaged ship with temporary necessities, such as meals, laundry, some supplies, and, in a limited number of cases, berthing for crew members. (When possible, the crew of the damaged ship remained on their ship while structural repair was being accomplished.)
