An Auxiliary repair dock is a type of vessel employed by the U.S. Navy, especially during World War II, when it commissioned 33 such vessels. == Primary use == The ''Auxiliary repair dock'' was actually a floating drydock, which could, by design, provide drydock facility to damaged Navy vessels. Floating drydocks of this type were approximately long and weighted about 5,000 tons. Several floating drydocks of this type have been given names, such as USS West Milton (ARD-7), but most of them have no name, only class designations, such as USS ARD-1. == Drydock facility == 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「auxiliary repair dock」の詳細全文を読む スポンサード リンク
