The 'Landing Ship Dock' or LSD developed from a British staff requirement for a type of self-propelled drydock to transport beaching craft over long distances, that would in turn deliver trucks and supplies onto the beach.[1] A flooding deck aft capable of holding either two of the larger British Landing craft tanks (LCTs) or three of the new US LCTs was included in the designs.[1] With the option of fitting extra decks, large numbers of vehicles could be transported, and loaded into landing craft via ramps. Despite an initial specification for a speed of 17 knots (20 mph; 31 km/h), the LSDs were capable of only 15.6 knots (18.0 mph; 28.9 km/h).[1]
The British initially ordered seven of the class from US dockyards, numbered LSD-9 to 15.[1] Only four were delivered, numbers 9 to 12, while 13 to 15 were retained by the US Navy, which ordered another twelve to the design, but only built ten.[1][2] In total thirteen of the ships served with the US Navy, while four ships served with the Royal Navy.[1]
