The Casa Grande class was a class of dock landing ships used by the Royal Navy and the United States Navy during the Second World War. Nineteen ships were planned, but two, and were cancelled before being completed.
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 17kn, the LSDs were capable of only 15.6kn.[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]
